SQL UPDATE
SQL UPDATE transfers the data prepared in the Q parameters into the
row of the result set addressed with INDEX. The existing row in the
result set is completely overwritten.
SQL UPDATE takes into account all columns entered in the "Select"
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).
Either enter the row number directly or program the
Q parameter containing the index
Row number is programmed directly
