lastInsertId
jump to class

lastInsertId(

              null
          )
        
        :
        string

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

As a convention, on RDBMS brands that support sequences (e.g. 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.

MySQL does not support sequences, so $tableName and $primaryKey are ignored.

Arguments

$tableName: string
OPTIONAL Name of table.
$primaryKey: string
OPTIONAL Name of primary key column.

Output

string

Details

visibility: public
final: false
static: false

        :
