CoalesceEmpty

Converges an empty cell value to a number or string and returns the specified value instead of empty.

Syntax

CoalesceEmpty(String_Expression1 [, String_Expression2])
CoalesceEmpty(Numeric_Expression1 [, Numeric_Expression2])

Arguments

String_Expression1	A valid string expression. Usually an MDX expression of cell coordinates that returns a string.
String_Expression2	A valid string expression that will be substituted for a NULL returned by the first string expression.
Numeric_Expression1	A valid numeric expression. Usually an MDX expression of cell coordinates that returns a number.
Numeric_Expression2	A valid numeric expression that will be substituted for a NULL returned by the first numeric expression.

Examples

When some string members need to be compared, CoalesceEmpty can be used to avoid comparing with null cells that can result in null pointer exception error.
