OLAP_EXPRESSION_TEXT

OLAP_EXPRESSION_TEXT is a SQL function that dynamically executes an OLAP DML text expression within the context of an OLAP_TABLE function. In addition to returning a custom measure, you can use this function in the WHERE and ORDER BY clauses to modify the result set of the query of the analytic workspace.

OLAP_EXPRESSION_TEXT returns character data. To return numeric, boolean, or date data, use OLAP_EXPRESSION, OLAP_EXPRESSION_BOOL, or OLAP_EXPRESSION_DATE SQL functions.

Before you use this function, you must specify a ROW2CELL clause in the limit map used by OLAP_TABLE. ROW2CELL identifies a RAW column that OLAP_TABLE populates with information used by the OLAP single-row functions.

Note:

You cannot execute this function from within the OLAP Worksheet. You must execute if in a SQL tool such as SQL Worksheet.

Returns

An evaluation of text_expression for each row of the table object returned by the OLAP_TABLE function.

          r2c               IN   RAW(32),
