About OLAP DML Expressions

An OLAP DML expression has a data type and can also have dimensions. You can use expressions as arguments in statements. An expression often performs a mathematical or logical operation. It always evaluates to a result in one of the workspace data types.

An expression can be:

• A literal value. For example, 10 or 'East'

• An analytic workspace object that contains multiple values. For example, the variable sales

• A function that returns one or more values. For example, TOTAL or JOINLINES

• Another expression that combines literal values, dimensions, variables, formulas, and functions with operators. For example, inflation*1.02

You can save an expression as a formula as described in "OLAP DML Formulas"
