Use cases

This library is particularly useful for:

Creating queries that can be used with different relational databases without the need of (bloated) ORM frameworks.
- Migration is usually achieved by changing a single line of code in your codebase.
Writing readable, typo-free SQL statements.
Building complex WHERE clauses (e.g. for filtering content) without the need of concatenating strings.
Migrating data from different relational databases.

Install

Requires PHP 8.1+

composer require phputil/sql

Note: Get updates via composer require phputil/sql since Composer is not able to get updates automatically via composer update for packages in version 0.x (pre-1.0).

Basic Usage

Queries

ℹ️ Use the function select() for creating a query and the method end() for finishing it.

require_once 'vendor/autoload.php';
use phputil\sql\{SQLType};
use function phputil\sql\{select};

// end() returns a Select object
$sql = select()->from( 'example' )->end();

// ... which is convertible to string
echo $sql; // SELECT * FROM example

// ... and it's convertible to specific databases via toString()
echo $sql->toString( SQLType::MYSQL );      // SELECT * FROM `example`
echo $sql->toString( SQLType::SQLSERVER );  // SELECT * FROM [example]

// Converting a query to a database-specific string
echo select()->from( 'example' )->end()->toString( SQLType::POSTGRESQL ); // SELECT * FROM "example"
echo select()->from( 'example' )->endAsString( SQLType::POSTGRESQL ); // SELECT * FROM "example"

// 👉 Setting the default SQL/database type globally with SQL::useXXX methods.
SQL::useSQLite();

echo $sql; // SELECT * FROM `example`

// But you can still convert it into another database
echo $sql->toString( SQLType::ORACLE ); // SELECT * FROM "example"

🆒 Okay, let's build a more complex query.

require_once 'vendor/autoload.php';
use phputil\sql\{SQL, SQLType};
use function phputil\sql\{select, col};

SQL::useMySQL();

// Say, all products with price between 100 and 999.999, quantity above 0,
// ordered by SKU and with a paginated result

$sql = select( 'p.sku', 'p.description', 'p.quantity', 'u.name AS unit', 'p.price' )
    ->from( 'product p' )
    ->leftJoin( 'unit u' )
        ->on( col( 'u.id' )->equalTo( col( 'p.unit_id' ) ) )
    ->where(
        col( 'p.price' )->between( 100.00, 999.99 )
        ->and( col( 'p.quantity' )->greaterThan( 0 ) )
    )
    ->orderBy( 'p.sku' )
    ->limit( 10 ) // limit to 10 rows
    ->offset( 20 ) // skip the first 20 rows (e.g., 3rd page in 10-row pagination)
    ->end();

echo $sql, PHP_EOL;

// It generates:
//
// SELECT `p`.`sku`, `p`.`description`, `p`.`quantity`, `u`.`name` AS `unit`, `p`.`price`
// FROM `product` `p`
// LEFT JOIN `unit` `u`
//   ON `u`.`id` = `p`.`unit_id`
// WHERE `p`.`price` BETWEEN 100 AND 999.99 AND `p`.`quantity` > 0
// ORDER BY `p`.`sku` ASC
// LIMIT 10
// OFFSET 20

echo $sql->toString( SQLType::ORACLE );

// Now it generates:
//
// SELECT "p"."sku", "p"."description", "p"."quantity", "u"."name" AS "unit", "p"."price"
// FROM "product" "p"
// LEFT JOIN "unit" "u"
//  ON "u"."id" = "p"."unit_id"
// WHERE "p"."price" BETWEEN 100 AND 999.99 AND "p"."quantity" > 0
// ORDER BY "p"."sku" ASC
// OFFSET 20 ROWS
// FETCH NEXT 10 ROWS ONLY

🤔 Right, but what about SQL Injection?

🆗 Just use parameters - with param() - for any input values.

👉 Your database must be able to handle parameters in SQL commands. Example with PDO:

// Getting an optional filter from the URL: /products?sku=123456
$sku = htmlspecialchars( $_GET[ 'sku' ] ?? '' );

// Example with named parameters using PDO
$sql = select( 'sku', 'description', 'price' )->from( 'product' );

if ( ! empty( $sku ) ) {
    $sql = $sql->where(
        col( 'sku' )->equal( param( 'sku' ) ) // 👈 Named parameter
    );
}

$pdo = new PDO( 'sqlite:example.db' );
$pdoStatement = $pdo->prepare( $sql );
$pdoStatement->execute( [ 'sku' => $sku ] ); // 👈 Value only here
// ...

➡️ See more examples in the API section or in the folder examples.

Data manipulation

ℹ️ Data manipulation functions do not require to use the end() method (it is optional).

1️⃣ Use deleteFrom() for creating a DELETE command. Example:

$command = deleteFrom( 'user' )->where( col( 'id' )->equalTo( param() ) )->end();
// DELETE FROM `user` WHERE `id` = ?

2️⃣ Use insertInto() for creating an INSERT command. Examples:

// Insert with field names and named parameters
$command = insertInto( 'user', [ 'name', 'username', 'password' ] )
    ->values(
        [ param( 'name' ), param( 'username' ), param( 'password' ) ]
    )->end();
// INSERT INTO `user` (`name`, `username`, `password`)
// VALUES (:name, :username, :password)


// Insert with values only
$command = insertInto( 'user' )->values(
    [ 1, 'Alice Foe', 'alice', 'aL1C3_passW0rD' ],
    [ 2, 'Bob Doe', 'bob', 'just_b0b' ],
)->end();
// INSERT INTO `user`
// VALUES
// (1, 'Alice Foe', 'alice', 'aL1C3_passW0rD'),
// (2, 'Bob Doe', 'bob', 'just_b0b')


// Insert from select
$command = insertInto( 'user', [ 'name', 'username', 'password' ],
    select( 'name', 'nickname', 'ssn' )->from( 'customer' )->end()
)->end();
// INSERT INTO `user` (`name`, `username`, `password`)
// SELECT `name`, `nickname`, `ssn` FROM `customer`

3️⃣ Use update() for creating an UPDATE command. Examples:

// Update with anonymous parameter and function
$command = update( 'user' )
    ->set( [ 'password' => param(), 'last_update' => now() ] )
    ->where( col( 'id' )->equalTo( 123 ) )
    ->endAsString( SQLType::MYSQL );
// UPDATE `user`
// SET `password` = ?, `last_update` = NOW()
// WHERE `id` = 123


$command = update( 'example' )
    ->set( [ 'a' => 10, 'b' => 'b + 1', 'c' => 'c + c * 50/100', 'd' => "'Hello'", 'e' => val( 'World' ) ] )
    ->where( col( 'id' )->equalTo( 1 ) )
    ->endAsString( SQLType::MYSQL );
// UPDATE `example`
// SET `a` = 10, `b` = `b` + 1, `c` = `c` + `c` * 50/100, `d` = 'Hello', `e` = 'World'
// WHERE `id` = 1

Types

`SQLType`

SQLType is an enum type with these values: NONE, MYSQL, POSTGRESQL, SQLITE, ORACLE, and SQLSERVER.

Example:

use phputil\sql\{SQLType};
use function phputil\sql\{select};

echo select()->from( 'example' )->endAsString( SQLType::NONE );
// SELECT * FROM example

`SQL`

SQL is a class with static attributes that keeps the default SQL type for queries.

use phputil\sql\{SQL};

echo SQL::$type; // Get the current database type - by default, it is SQLType::NONE

// The following methods change SQL::$type
SQL::useNone(); // No specific SQL type - that is, change to SQLType::NONE
SQL::useMySQL(); // Change to SQLType::MYSQL
SQL::usePostgreSQL(); // Change to SQLType::POSTGRESQL
SQL::useSQLite(); // Change to SQLType::SQLITE
SQL::useOracle(); // Change to SQLType::ORACLE
SQL::useSQLServer(); // Change to SQLType::SQLSERVER

Basic functions

// 👉 Make sure to declare their usage. Example:
use function phputil\sql\{select, col, val, param, wrap};

`select`

Create a selection. Examples:

$sql = select()->from( 'user' )->end();
// SELECT * FROM `user`

$sql = select( 'name', 'email' )
    ->from( 'user' )
    ->where( col( 'id' )->equalTo( 123 ) )
    ->end();
// SELECT `name`, `email` FROM `user` WHERE `id` = 123

👉 from() returns a From object with the following methods:

join( string $table ): Join
innerJoin( string $table ): Join
leftJoin( string $table ): Join
rightJoin( string $table ): Join
fullJoin( string $table ): Join
crossJoin( string $table ): From
naturalJoin( string $table ): From
where( Condition $condition ): From
whereExists( Select $select ): From
groupBy( string ...$columns ): From
having( Condition $condition ): From
orderBy( string ...$columns ): From
union( Select $select ): From
unionDistinct( Select $select ): From

Example with having:

echo select( count( 'id' ), 'country' )
    ->from( 'customer' )
    ->groupBy( 'country' )
    ->having( val( count( 'id' ) )->greaterThan( 5 ) )
    ->orderBy( desc( count( 'id' ) ) )
    ->endAsString( SQLType::MYSQL );

// SELECT COUNT(`id`), `country`
// FROM `customer`
// GROUP BY `country`
// HAVING COUNT(`id`) > 5
// ORDER BY COUNT(`id`) DESC

`selectDistinct`

Create a distinct selection. It can receive one or more columns. Examples:

$sql = selectDistinct( 'name' )
    ->from( 'customer' )
    ->where( col( 'name' )->like( 'John%' ) )
    ->end();
// SELECT DISTINCT `name` FROM `customer` WHERE `name` LIKE 'John%'

`insertInto`

insertInto( string $table, string[] $fields = [], ?Select $select = null ) creates an INSERT command.

// With no fields declared, but they are: id, name, email
$command = insertInto( 'contact' )
    ->values(
        [ 1, 'John Doe', 'john@doe.com' ],
        [ 2, 'Suzan Foe', 'suzan@foe.com' ],
    )->end();
// INSERT INTO `contact`
// VALUES
// (1, 'John Doe', 'john@doe.com'),
// (2, 'Suzan Foe', 'suzan@foe.com')


// With fields declared, considering an auto-incremental id
$command = insertInto( 'contact', [ 'name', 'email' ] )
    ->values(
        [ 'John Doe', 'john@doe.com' ],
        [ 'Suzan Foe', 'suzan@foe.com' ],
    )->end();
// INSERT INTO `contact` (`name`, `email`)
// VALUES
// ('John Doe', 'john@doe.com'),
// ('Suzan Foe', 'suzan@foe.com')


// With anonymous parameters
$command = insertInto( 'contact', [ 'name', 'email' ] )
    ->values(
        [ param(), param() ]
    )->end();
// INSERT INTO `contact` (`name`, `email`) VALUES (?, ?)


// With named parameters
$command = insertInto( 'contact', [ 'name', 'email' ] )
    ->values(
        [ param( 'name' ), param( 'email' ) ]
    )->end();
// INSERT INTO `contact` (`name`, `email`) VALUES (:name, :email)


// From selection
$command = insertInto( 'contact', [ 'name', 'email' ],
        select( 'name', 'email' )->from( 'customer' )
            ->where( col( 'email' )->endWith( '@acme.com' ) )
            ->end()
    )->end();
// INSERT INTO `contact` (`name`, `email`)
// SELECT `name`, `email` FROM `customer`
// WHERE `email` LIKE '%@acme.com'

`update`

update creates an UPDATE command. Example:

$command = update( 'user' )
    ->set(
        [ 'password' => val( '123456' ), 'last_update' => now() ]
    )->where(
        col( 'id' )->equalTo( 123 )
    )->end();
// UPDATE `user`
// SET `password` = '123456', `last_update` = NOW()
// WHERE `id` = 123

`deleteFrom`

deleteFrom creates a DELETE command. Example:

// With anonymous parameter
$command = deleteFrom( 'user' )
    ->where( col( 'id' )->equalTo( param() ) )
    ->end();
// DELETE FROM `user` WHERE `id` = ?


// With named parameter
$command = deleteFrom( 'user' )
    ->where( col( 'id' )->equalTo( param( 'id' ) ) )
    ->end();
// DELETE FROM `user` WHERE `id` = :id

`col`

col makes a column comparison and makes sure that the column is quoted appropriately. Examples:

$sql = select( 'total' )->from( 'sale' )->where( col( 'id' )->equalTo( 123 ) )->end();
// SELECT `total` FROM `sale` WHERE `id` = 123

$sql = select( 'id' )->from( 'product' )->where( col( 'qty' )->lessThan( col( 'min_qty' ) ) )->end();
// SELECT `id` FROM `product` WHERE `qty` < `min_qty`

$sql = select( 'name' )->from( 'product' )->where( col( 'special' )->isTrue() )->end();
// SELECT `name` FROM `product` WHERE `special` IS TRUE

$sql = select( 'id' )->from( 'sale' )->where( col( 'customer_id' )->in( [ 1234, 4567, 7890 ] ) )->end();
// SELECT `id` FROM `sale` WHERE `customer_id` IN (1234, 4567, 7890)

// Sub-select
$sql = select( 'id' )->from( 'sale' )->where( col( 'customer_id' )->in(
    select( 'id' )->from( 'customer' )->where( col( 'salary' )->greaterThan( 100_000 ) )
) )->end();
// SELECT `id` FROM `sale` WHERE `customer_id` IN (SELECT `id` FROM `customer` WHERE `salary` > 100000)

col returns the following comparison methods:

equalTo( $x ) for =
notEqualTo( $x ) or differentFrom( $x ) for <>
lessThan( $x ) for <
lessThanOrEqualTo( $x ) for <=
greaterThan( $x ) for >
greaterThanOrEqualTo( $x ) for >=
like( $value ) for LIKE
startWith( $value ) for LIKE with % at the beginning of the value
endWith( $value ) for LIKE with % at the end of the value
contain( $value ) for LIKE with % around the value
between( $min, $max ) for BETWEEN with a minimum and a maximum value
in( $selectionOrArray ) for a sub select statement or an array of values
isNull() for IS NULL
isNotNull() for IS NOT NULL
isTrue() for IS TRUE
isFalse() for IS FALSE

ℹ️ Notes:

Methods startWith, endWith, and contain produce a LIKE expression that adds % to the receive value. However, when an anonymous (?) or a named (:name) parameter is received by them, they will not add %, and you must add % manually to the parameter values.
In Oracle databases, the methods isTrue() and isFalse() are supported from Oracle version 23ai. In older versions, you can use equalTo(1) and equalTo(0) respectively, for the same results.

👉 col can also be used for creating aliases, with the as method. For instance, these three examples are equivalent:

$sql = select( col( 'long_name' )->as( 'l' ) );
$sql = select( col( 'long_name AS l' ) );
$sql = select( 'long_name AS l' );

`val`

val( $value ) allows a value to be in the left side of a comparison. Example:

$sql = select( 'total' )->from( 'sale' )->where( val( 123 )->equalTo( col( 'id' ) ) )->end();
// SELECT `total` FROM `sale` WHERE 123 = `id`

ℹ️ Note: val returns the same comparison operators as col.

val can also be used in a select statement for defining values or functions. Example:

$sql = select( val( 1 ) );
// SELECT 1

`param`

param establishes an anonymous or named parameter. Examples:

// Calling param() without an argument makes an anonymous parameter
$sql = select( 'total' )->from( 'sale' )->where( col( 'id' )->equalTo( param() ) )->end();
// SELECT `total` FROM `sale` WHERE `id` = ?

// Calling param() with an argument makes a named parameter
$sql = select( 'total' )->from( 'sale' )->where( col( 'id' )->equalTo( param( 'id' ) ) )->end();
// SELECT `total` FROM `sale` WHERE `id` = :id

`wrap`

wrap adds parenthesis around a condition. Example:

$sql = select( 'id' )->from( 'sale' )
    ->where(
        col( 'total' )->greaterThanOrEqualTo( 100 )
        ->and( wrap(
            col( 'customer_id' )->equalTo( 1234 )
            ->or( col( 'customer_id' )->equalTo( 4567 ) )
        ) )
    )->end();
// SELECT `id` FROM `sale`
// WHERE `total` >= 100 AND (`customer_id` = 1234 OR `customer_id` = 4567)

`not`

not negates a condition. Example:

$sql = select( 'name' )->from( 'customer' )
    ->where(
        not( col( 'name' )->like( '% % %' ) )
    )->end();
// SELECT `name` FROM `customer`
// WHERE NOT(`name` LIKE '% % %')

Logic utilities

These are especially useful for creating a WHERE condition that unites a bunch of other conditions with the same logic operator.

`andAll`

andAll() concatenates all the received conditions with the AND operator. Example:

$condition = andAll(
    col( 'description' )->startWith( 'Mouse' ),
    col( 'price' )->lessThanOrEqualTo( 300.00 )
);

$sql = select()->from( 'product' )->where( $condition )->end();
// SELECT * FROM `product`
// WHERE `description` LIKE 'Mouse%' AND `price` <= 300

ℹ️ Tip: You can use the spread operator (...) for passing an array of conditions to andAll(). Just make sure that your array is not empty, before doing that.

`orAll`

orAll() concatenates all the received conditions with the OR operator. Example:

$condition = orAll(
    col( 'description' )->startWith( 'Mouse' ),
    col( 'sku' )->contain( 'MZ' )
);

$sql = select()->from( 'product' )->where( $condition )->end();
// SELECT * FROM `product`
// WHERE `description` LIKE 'Mouse%' OR `sku` LIKE '%MZ%'

ℹ️ Tip: You can use the spread operator (...) for passing an array of conditions to orAll(). Just make sure that your array is not empty, before doing that.

Ordering utilities

`asc`

asc() indicates an ascending sort order. Its usage is optional. Example:

$sql = select()->from( 'example' )->orderBy( 'a', asc( 'b' ) )->end();
// SELECT * FROM `example` ORDER BY `a` ASC, `b` ASC

`desc`

desc() makes an descending sort. Example:

$sql = select()->from( 'example' )->orderBy( 'a', desc( 'b' ) )->end();
// SELECT * FROM `example` ORDER BY `a` ASC, `b` DESC

Aggregate functions

Aggregate functions can receive an alias as a second argument or use the method as to define an alias. For instance, these two commands are equivalent:

// Alias using the method as()
$sql = select(
        'date',
        sum( 'price * quantity' )->as( 'subtotal' ), // 👈
    )->from( 'sale' )
    ->groupBy( 'date' )
    ->end();

// Alias as the second argument
$sql = select(
        'date',
        sum( 'price * quantity', 'subtotal' ), // 👈
    )->from( 'sale' )
    ->groupBy( 'date' )
    ->end();

`count`

$sql = select( count( 'id' ) )->from( 'sale' )->end();

`countDistinct`

$sql = select( countDistinct( 'phone_number' ) )->from( 'contact' )->end();

`sum`

$sql = select( sum( 'total' ) )->from( 'order' )->end();

`sumDistinct`

$sql = select( sumDistinct( 'commission' ) )->from( 'sale' )->end();

`avg`

$sql = select( avg( 'price' ) )->from( 'product' )->end();

`avgDistinct`

$sql = select( avgDistinct( 'receive_qty' ) )->from( 'purchase' )->end();

`min`

$sql = select( min( 'price' ) )->from( 'product' )->end();

`max`

$sql = select( max( 'price' ) )->from( 'product' )->end();

Date and Time functions

`now`

now() returns the current date and time, in most databases. Example:

$sql = select( now() );
// MySQL        : SELECT NOW()
// PostgreSQL   : SELECT NOW()
// SQLite       : SELECT DATETIME('now')
// Oracle       : SELECT SYSDATE
// SQLServer    : SELECT CURRENT_TIMESTAMP

`date`

date() returns the current date. Example:

$sql = select( date() );
// MySQL        : SELECT CURRENT_DATE
// PostgreSQL   : SELECT CURRENT_DATE
// SQLite       : SELECT CURRENT_DATE
// Oracle       : SELECT SYSDATE
// SQLServer    : SELECT GETDATE()

`time`

time() returns the current time, in most databases. Example:

$sql = select( time() );
// MySQL        : SELECT CURRENT_TIME
// PostgreSQL   : SELECT CURRENT_TIME
// SQLite       : SELECT CURRENT_TIME
// Oracle       : SELECT CURRENT_TIMESTAMP
// SQLServer    : SELECT CURRENT_TIMESTAMP

`extract`

extract() can extract a piece of a column or a date/time/timestamp value. Examples:

use phputil\sql\{SQLType, Extract};
use function phputil\sql\{select, extract};

$sql = select( extract( Extract::DAY, 'col1' ) )
    ->from( 'example' )->endAsString( SQLType::MYSQL );
// SELECT EXTRACT(DAY FROM `col1`) FROM `example`

$sql = select( extract( Extract::DAY, val( '2025-12-31' ) ) )
    ->toString( SQLType::MYSQL );
// SELECT EXTRACT(DAY FROM '2025-12-31')

This is the Extract enum:

enum Extract {
    case YEAR;
    case MONTH;
    case DAY;

    case HOUR;
    case MINUTE;
    case SECOND;
    case MICROSECOND;

    case QUARTER;
    case WEEK;
    case WEEK_DAY;
}

`diffInDays`

diffInDays returns the difference in days from two dates/timestamps.

echo select( diffInDays( val( '31-12-2024' ), now() ) )
    ->toString( SQLType:MYSQL );
// SELECT DATEDIFF('31-12-2024', NOW())

echo select( diffInDays( 'birthdate', now() ) )->from( 'example' )
    ->toString( SQLType:MYSQL );
// SELECT DATEDIFF(`birthdate`, NOW()) FROM `example`

`addDays`

String functions

All string functions can have an alias, using as(). Example:

$sql = select(
    concat( 'first_name', 'last_name' )->as( 'full_name' )
)->from( 'customer' )->end();

// SELECT CONCAT(`first_name`, `last_name`) AS `full_name` FROM `customer`

`upper`

upper( $textOrColumn ) converts a text or column to uppercase. Example:

$sql = select( upper( 'name' ) )->from( 'customer' )->end();
//  SELECT UPPER(`name`) FROM `customer`

`lower`

lower( $textOrColumn ) converts a text or column to lowercase. Example:

$sql = select( lower( 'name' ) )->from( 'customer' )->end();
// SELECT LOWER(`name`) FROM `customer`

`substring`

substring( $textOrColumn, int $startingIndex, ?int $length = null ) gets a piece of a text or column.

$startingIndex starts at 1;
$length is optional.

Examples:

$sql = select( substring( 'name', 1, 5 ) ) )->from( 'customer' )->end();
// SELECT SUBSTRING(`name`, 1, 5) FROM `customer`

$sql = select( substring( val( 'Hello, world' ), 8 ) ) );
// SELECT SUBSTRING('Hello, world', 8)

`concat`

concat( $textOrColumn1, $textOrColumn2, ...$textOrColumnN ) concatenates strings or fields. Example:

$sql = select(
    concat( 'first_name', 'last_name' )->as( 'name' )
)->from( 'customer' )->end();

// SELECT CONCAT(`first_name`, `last_name`) AS `name` FROM `customer`

`length`

length( $textOrColumn ) returns the length of a text or a (string) column. Example:

$sql = select( length( 'name' ) )->from( 'customer' )->end();
// SELECT CHAR_LENGTH(`name`) FROM `customer`

`bytes`

bytes( $textOrColumn ) returns the size in bytes of a text or a (string) column. Example:

$sql = select( bytes( 'name' ) )->from( 'customer' )->end();
// SELECT LENGTH(`name`) FROM `customer`

Null handling function

`ifNull`

ifNull( $valueOrColumm, $valueOrColumnIfNull ) creates a fallback value for a column when it is null. Examples:

$sql = select( 'name', ifNull( 'nickname', val( 'anonymous' ) ) )
    ->from( 'user' )->end();
// SELECT `name`, COALESCE(`nickname`, 'anonymous') FROM `user`

$sql = select( 'name', ifNull( 'nickname', 'name' ) )
    ->from( 'user' )->end();
// SELECT `name`, COALESCE(`nickname`, `name`) FROM `user`

Math functions

Math functions can receive a field, a value or an expression.

All of them have a method as() to define an alias. Example:

$sql = select(
