README

This library provides a fluent interface for generating SQL statement strings.

The DBAL library extends this library with a wrapper for PDO.

Installation

composer require wtframework/sql

Documentation

Supported grammars

  • MariaDB
  • MySQL
  • PostgreSQL
  • SQLite
  • TSQL

Supported statements

Example

use WTFramework\SQL\SQL;

echo $stmt = SQL::select()
->from('users')
->where('email_address', 'admin@example.net');
SELECT * FROM users WHERE email_address = ?


After casting the object to a string, like above, the bindings method will return an array of bound parameters.

print_r($stmt->bindings());
Array
(
    [0] => admin@example.net
)

Grammars

The default global grammar is MySQL. Use the static SQL::use method to change this. This will not apply to any existing statements.

use WTFramework\SQL\Grammar;

$stmt1 = SQL::select();

SQL::use(Grammar::TSQL);

$stmt2 = SQL::select();

// $stmt1 will use MySQL, $stmt2 will use TSQL.


The use method can also be used to override the grammar of an individual statement.

$stmt1->use(Grammar::PostgreSQL);

Simple SQL

A simple implementation of the library is also provided, using a subset of the statements, clauses, and services.

Supported statements

use WTFramework\SQL\Simple\SQL;

$stmt = SQL::delete();
$stmt = SQL::insert();
$stmt = SQL::replace();
$stmt = SQL::select();
$stmt = SQL::truncate();
$stmt = SQL::update();

Delete

Supported clauses:

$stmt->ignore();
$stmt->top($row_count);
$stmt->table($table);
$stmt->from($table);
$stmt->join($table);
$stmt->using($table);
$stmt->where($column, $value);
$stmt->orderBy($column);
$stmt->limit($row_count);
$stmt->offset($offset);

Insert

Supported clauses:

$stmt->ignore();
$stmt->top($row_count);
$stmt->into($table);
$stmt->column($column);
$stmt->values($values);
$stmt->set($column, $value);
$stmt->select($stmt);
$stmt->onDuplicateKeyUpdate($column, $value);
$stmt->onConflict($upsert);

Replace

Supported clauses:

$stmt->into($table);
$stmt->column($column);
$stmt->values($values);
$stmt->set($column, $value);
$stmt->select($stmt);

Select

Supported clauses:

$stmt->distinct();
$stmt->top($row_count);
$stmt->column($column);
$stmt->from($table);
$stmt->join($table);
$stmt->where($column, $value);
$stmt->groupBy($column);
$stmt->having($column, $value);
$stmt->union($stmt);
$stmt->orderBy($column);
$stmt->limit($row_count);
$stmt->offset($offset);
$stmt->offsetRows($offset);
$stmt->fetchRows($row_count);

Truncate

Supported clauses:

$stmt->table($table);

Update

Supported clauses:

$stmt->ignore();
$stmt->top($row_count);
$stmt->table($table);
$stmt->from($table);
$stmt->join($table);
$stmt->set($column, $value);
$stmt->where($column, $value);
$stmt->orderBy($column);
$stmt->limit($row_count);
$stmt->offset($offset);

Supported services

use WTFramework\SQL\Simple\SQL;

SQL::bind($value);
SQL::raw($string);
SQL::subquery($stmt);
SQL::table($name);
SQL::upsert();

Extending the library

To extend the library you can use the static macro method, passing the new method name and a closure to call. This works for both static and non-static methods. This is available on the SQL class as well as all statement and service classes.

use WTFramework\SQL\SQL;

SQL::macro('count', function (string $table)
{

  return static::select()
  ->column('COUNT(*) AS counter')
  ->from($table);

});
SQL::count('users');
