Associative array of datatypes to values 0, 1, or 2.

Values are: 0 = 32-bit integer 1 = 64-bit integer 2 = float or decimal

Default valuearray( Zend_Db::INT_TYPE => Zend_Db::INT_TYPEDetails

methodpubliclastInsertId( string $tableName = null, string $primaryKey = null ) : string

Gets the last ID generated automatically by an IDENTITY/AUTOINCREMENT column.

As a convention, on RDBMS brands that support sequences (e.g. Firebird, Oracle, PostgreSQL, DB2), this method forms the name of a sequence from the arguments and returns the last id generated by that sequence. On RDBMS brands that support IDENTITY/AUTOINCREMENT columns, this method returns the last value generated for such a column, and the table name argument is disregarded.

Firebird does not support IDENTITY columns, so if the sequence is not specified, this method returns null.

Parameters
Name Type Description
$tableName string

OPTIONAL Name of table.

$primaryKey string

OPTIONAL Name of primary key column.

Returns
Type Description
string
Throws
Exception Description
\ZendX_Db_Adapter_Firebird_Exception
