Method Details

alterColumn() public method

Builds a SQL statement for changing the definition of a column.

public string alterColumn ( $table, $column, $type )
$table	string	The table whose column is to be changed. The table name will be properly quoted by the method.
$column	string	The name of the column to be changed. The name will be properly quoted by the method.
$type	string	The new column type. The getColumnType() method will be invoked to convert abstract column type (if any) into the physical one. Anything that is not recognized as abstract type will be kept in the generated SQL. For example, 'string' will be turned into 'varchar(255)', while 'string not null' will become 'varchar(255) not null'. You can also use PostgreSQL-specific syntax such as `SET NOT NULL`.
return	string	The SQL statement for changing the definition of a column.

batchInsert() public method

Generates a batch INSERT SQL statement.

For example,

$sql = $queryBuilder->batchInsert('user', ['name', 'age'], [
    ['Tom', 30],
    ['Jane', 20],
    ['Linda', 25],
]);

Note that the values in each row must match the corresponding column names.

The method will properly escape the column names, and quote the values to be inserted.

$columns	array	The column names
$rows	array	The rows to be batch inserted into the table
return	string	The batch INSERT SQL statement

checkIntegrity() public method

Builds a SQL statement for enabling or disabling integrity check.

public string checkIntegrity ( $check = true, $schema = '', $table = '' )
$check	boolean	Whether to turn on or off the integrity check.
$schema	string	The schema of the tables.
$table	string	The table name.
return	string	The SQL statement for checking integrity

createIndex() public method

Builds a SQL statement for creating a new index.

public string createIndex ( $name, $table, $columns, $unique = false )
$name	string	The name of the index. The name will be properly quoted by the method.
$table	string	The table that the new index will be created for. The table name will be properly quoted by the method.
$columns	string\|array	The column(s) that should be included in the index. If there are multiple columns, separate them with commas or use an array to represent them. Each column name will be properly quoted by the method, unless a parenthesis is found in the name.
$unique	boolean\|string	Whether to make this a UNIQUE index constraint. You can pass `true` or INDEX_UNIQUE to create a unique index, `false` to make a non-unique index using the default index type, or one of the following constants to specify the index method to use: INDEX_B_TREE, INDEX_HASH, INDEX_GIST, INDEX_GIN.
return	string	The SQL statement for creating a new index.

dropIndex() public method

Builds a SQL statement for dropping an index.

public string dropIndex ( $name, $table )
$name	string	The name of the index to be dropped. The name will be properly quoted by the method.
$table	string	The table whose index is to be dropped. The name will be properly quoted by the method.
return	string	The SQL statement for dropping an index.

insert() public method

Creates an INSERT SQL statement.

For example,

$sql = $queryBuilder->insert('user', [
