base.SqlHandle.fetch

Syntax

fetch()

Usage

Call the fetch() method to fetch a new row from the SQL result set.

The SQL statement must have been opened with a open() 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).

As with standard Genero SQL instructions, SQL errors can be trapped with WHENEVER ERROR or TRY / CATCH blocks and by testing SQLCA.SQLCODE.
