base.SqlHandle.fetchLast
Fetches the last row in a scrollable SQL result set.
Syntax
fetchLast()Usage
Call the fetchLast() method to fetch the last row in a scrollable SQL result
set.
The SQL statement must have been opened with an openScrollCursor()
call.
After performing the fetch call, you can query for column information
with the getResultCount(), getResultName(index), getResultType(index) and getResultValue(index) methods.
If no row is found (end of result set), sqlca.sqlcode is set to 100 (NOTFOUND).
If the result set is empty, sqlca.sqlcode is set to 100 (NOTFOUND).
As with standard Genero SQL instructions, SQL errors can be trapped
with WHENEVER ERROR or TRY / CATCH blocks and by testing
sqlca.sqlcode.
Example
DEFINE sh base.SqlHandle
...
CALL sh.fetchLast()For a complete example, see Example 4: SqlHandle with scroll cursor.
