Conditions

A condition is a combination of expressions and operators that evaluate to TRUE or FALSE.

You can use conditions to search, filter, and test rows in:

Restriction filters
The WHERE clause of the SELECT, UPDATE, and DELETE commands
The HAVING clause of the SELECT GROUP BY command
The WHEN clause in triggers
The IF THEN ELSE, CASE WHEN, and FOR EACH ROW statements in procedures and triggers

Conditions can contain comparison operators (Severity < 3), logical operators (NOT(Is_Enabled)), and list comparison operators (Severity IN ANY(0,5)).

Valid conditions are shown in the following list:

TRUE | FALSE
( condition )
NOT condition
condition AND condition
condition OR condition
expression operator expression
expression operator ANY ( expression, ... )
expression operator ALL ( expression, ... )
expression[ NOT ] IN( subquery )
expression operator ANY ( subquery )
expression [ NOT ] IN ( expression, ... )
expression [ NOT ] LIKE regexp_pattern
expression [ NOT ] LIKE ANY ( regexp_pattern, ... )
expression [ NOT ] LIKE ALL ( regexp_pattern, ... )

Note: The ANY and ALL operators are not supported in subqueries.

You can combine conditions into increasingly complex conditions.

Example

(Severity > 4) AND (Node = 'node%')

The following example shows the use of a condition in a subquery:

select * from alerts.status where Serial in (select Serial from alerts.journal);
