SQL programmingYou can use the HCL OneDB™ implementation of the SQL language to develop applications for HCL OneDB™ database servers.
Guide to SQL: SyntaxThe HCL OneDB™ Guide to SQL: Syntax describes the syntax of the statements, data types, expressions, operators, and built-in functions of the HCL OneDB™ dialect of the SQL language.
SQL statementsThis chapter describes the syntax and semantics of SQL statements that are recognized by HCL OneDB™.
WHENEVER statementUse the WHENEVER statement to trap exceptions that occur during the execution of SQL statements. The WHENEVER statement is equivalent to placing an exception-checking routine after every SQL statement.
SQLERROR Keyword

SQLERROR Keyword

If you use the SQLERROR keyword, any SQL statement that encounters an error is handled as the WHENEVER SQLERROR statement directs. If an error occurs, the sqlcode variable (sqlca.sqlcode, SQLCODE) is set to a value less than zero (0) and the SQLSTATE variable is set to a class code with a value greater than 02.

The next example terminates program execution if an SQL error is detected:

WHENEVER SQLERROR STOP

If you do not include any WHENEVER SQLERROR statements in a program, the default action for WHENEVER SQLERROR is CONTINUE.
