SQL UPDATE changes a row in the result set (intermediate
memory). The new values of the individual cells are copied from
the bound Q parameters. The transaction is defined via the
HANDLE to be specified; the row is defined via the INDEX. The
existing row in the result set is completely overwritten.
SQL UPDATE takes all columns into consideration that were
specified with the SELECT instruction (SQL command SQL
EXECUTE).
Parameter No. for result (return value for the
control):
0 successful transaction
1 successful transaction
Database: SQL access ID: Define Q parameters
for the HANDLE (for identifying the transaction)
Database: Index for SQL result: Row number
within the result set
Program the row number directly
Program the Q parameter containing the
index
The row (n=0) is assigned a value if none is
specified
