SQL FETCH

SQL FETCH reads a row from the result set. The values of the
individual cells are stored by the control in the bound Q parameters.
The transaction is defined through the HANDLE to be specified, and
the row is defined by the INDEX.
SQL FETCH takes all of the columns into consideration that contain
the SELECT instruction (SQL command SQL EXECUTE).
