public array $typeMap = [\yii\db\pgsql\Schema::TYPE_PK => 'serial NOT NULL PRIMARY KEY', \yii\db\pgsql\Schema::TYPE_UPK => 'serial NOT NULL PRIMARY KEY', \yii\db\pgsql\Schema::TYPE_BIGPK => 'bigserial NOT NULL PRIMARY KEY', \yii\db\pgsql\Schema::TYPE_UBIGPK => 'bigserial NOT NULL PRIMARY KEY', \yii\db\pgsql\Schema::TYPE_CHAR => 'char(1)', \yii\db\pgsql\Schema::TYPE_STRING => 'varchar(255)', \yii\db\pgsql\Schema::TYPE_TEXT => 'text', \yii\db\pgsql\Schema::TYPE_TINYINT => 'smallint', \yii\db\pgsql\Schema::TYPE_SMALLINT => 'smallint', \yii\db\pgsql\Schema::TYPE_INTEGER => 'integer', \yii\db\pgsql\Schema::TYPE_BIGINT => 'bigint', \yii\db\pgsql\Schema::TYPE_FLOAT => 'double precision', \yii\db\pgsql\Schema::TYPE_DOUBLE => 'double precision', \yii\db\pgsql\Schema::TYPE_DECIMAL => 'numeric(10,0)', \yii\db\pgsql\Schema::TYPE_DATETIME => 'timestamp(0)', \yii\db\pgsql\Schema::TYPE_TIMESTAMP => 'timestamp(0)', \yii\db\pgsql\Schema::TYPE_TIME => 'time(0)', \yii\db\pgsql\Schema::TYPE_DATE => 'date', \yii\db\pgsql\Schema::TYPE_BINARY => 'bytea', \yii\db\pgsql\Schema::TYPE_BOOLEAN => 'boolean', \yii\db\pgsql\Schema::TYPE_MONEY => 'numeric(19,4)', \yii\db\pgsql\Schema::TYPE_JSON => 'jsonb']

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

{@inheritdoc}

public void batchInsert ( $table, $columns, $rows, &$params = [] )
$table
$columns
$rows
$params
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

$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.
