result set is completely overwritten.

command.

Parameter no. for result: Q parameter, in which
the SQL server has reported the result:
0: No error occurred
1: Error occurred (incorrect handle, index too large,
value outside of value range or incorrect data
format)
Database: SQL access ID: Q parameter with the

handle

for identifying the result set (also see

SQL

SELECT).
Database: Index to SQL result: Line number within
the result set. The table entries prepared in the Q
parameters are written to this row. If you do not
enter an index, the first row is written to (n=0).
