Exception classes

Exception classes indirectly define the exception type.

The default action can be changed by specifying the exception class in the WHENEVER instruction.

Table 1. Exception classes
Class	Error reason	Default Action
`ERROR (or SQLERROR)`	Language or SQL statement error.	`STOP`
`ANY ERROR (or ANY SQLERROR)`	Language, SQL statement and expression error.	`CONTINUE` (1)
`NOT FOUND`	SQL statements returning status `NOTFOUND`.	`CONTINUE`
`WARNING`	SQL statements setting `sqlca.sqlawarn` flags.	`CONTINUE`

For example, the following WHENEVER instruction defines the behavior for the ANY ERROR exception class:

WHENEVER ANY ERROR CONTINUE
