Syntax Elements

expression_1
An SQL scalar expression, including derived period expressions.
Comparison operators do not support BLOB or CLOB type expressions. You can explicitly cast BLOBs to BYTE or VARBYTE and cast CLOBs to CHARACTER or VARCHAR, and use the result with comparison operators.
operator
A comparison operator—see Supported Comparison Operators.
expression_2
An SQL scalar expression, including derived period expressions.
quantifier
One of the following quantifier keywords:
  • ANY
  • SOME
  • ALL
literal
Any of the following:
  • Defined value
  • Macro parameter
  • Built-in value such as TIME, DATE, or USER
The comparison operation may compare an expression against a list of explicit literals.
The data types of expression and literal must be compatible. If the data types of the operands differ, Vantage may perform an implicit conversion from one type to another.
subquery
An SQL SELECT statement.
Using a subquery in a condition is restricted in certain cases.
