SQLCA.SQL-CODE, you can know whether the last fetch statement was successful. Generally, when the sqlcode value is0 indicates that everything is normal, 100 indicates that the result set has been obtained at the end, and other values indicate that the operation is faulty, so we can write the following code:Lb_continue = trueLl_total = 0Do While lb_continueFetch customercur-sorInto: ls_acct_no,: Ls_name,: Ll_balance;If sqlca.

exception is the same as the built-in exception, then when you reference the exception, it will solve your exception instead of the built-in exception. Name the database incorrectly If you want to handle an exception, you must have a name for the exception. There are thousands of database errors, but less than 25 are built-in named exceptions. However, if you need to handle these unnamed exceptions, you can associate a name with an error code. To achieve this purpose, the Pragma exception_i
