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™.
SET Database Object Mode statementUse the SET Database Object Mode statement to change the filtering mode of constraints and of unique indexes, or to enable or disable constraints, indexes, and triggers, or to bypass referential-integrity checking of constraints while this statement is resetting the constraint mode.
Definitions of Database Object Modes
Filtering ModesA constraint or unique index in a filtering mode can insert into an associated violations table any rows that fail to comply with the constraint or index during DML operation. This mode also supports WITH ERROR and WITHOUT ERROR options for processing referential-integrity violations from INSERT, DELETE, MERGE, and UPDATE statements.
Starting and Stopping the Violations and Diagnostics Tables

Starting and Stopping the Violations and Diagnostics Tables

About this task

You must use the START VIOLATIONS TABLE statement to start the violations and diagnostics tables for the target table on which the database objects are defined, either before you set any database objects that are defined on the table to the filtering mode, or after you set database objects to filtering, but before any users issue INSERT, DELETE, or UPDATE statements.

If you want to stop the database server from filtering bad records to the violations table and sending diagnostic information about each bad record to the diagnostics table, you must issue a STOP VIOLATIONS TABLE statement.

For further information on these statements, see START VIOLATIONS TABLE statement and STOP VIOLATIONS TABLE statement.
