SQLSUM
The SQLSUM
function returns the sum of its arguments.
Description
The SQLSUM function is an AtScale extension to MDX. It is an alternative
to the +
operator, which requires special NULL-handling semantics in
the outbound queries generated by AtScale. This function can be used to
sum values and simplifies the syntax of outbound SQL queries, because
AtScale does not have to add syntax to check for NULLs when it converts
MDX to SQL.
You can use this function on place of the + operator when:
- All measure input values are from the same fact dataset
- You are sure your input expressions do not produce NULL values (or you have syntax to check for NULL values in your input expression)
Syntax
SQLSUM(numeric_expression,numeric_expression[,...])
Return Value
Returns the sum of its input arguments.
Input Parameters
numeric_expression

value.
