Method Detail

checkResultTypes   [line 140]

mixed checkResultTypes( array $types)

Define the list of types to be associated with the columns of a given result set.

This function may be called before invoking fetchRow(), fetchOne() fetchCole() and fetchAll() so that the necessary data type conversions are performed on the data to be retrieved by them. If this function is not called, the type of all result set columns is assumed to be text, thus leading to not perform any conversions.

  • Return: MDB2_OK on success, a MDB2 error on failure
  • Access: public

Parameters:

array   $types   —   array variable that lists the data types to be expected in the result set columns. If this array contains less types than the number of columns that are returned in the result set, the remaining columns are assumed to be of the type text. Currently, the types clob and blob are not fully supported.
