%OPR_CONCAT%

Uses the CONCAT function and expands an expression in an expression macro to concatenate multiple fields. %OPR_CONCAT% converts all data to text, and then concatenates the fields.

Syntax

%OPR_CONCAT[ macro_input_field ]%

The following table describes the argument for this function:

Argument	Required/ Optional	Description
macro_input_field	Required	Any datatype except Binary. You can use a set of incoming fields or a set of constants. You can enter a macro input field or an expression that includes at least one macro input field.

Return Value

String.

NULL if all strings in the set of fields are NULL.

Returns NULL if all strings are null. Otherwise, ignores the null values and concatenates the strings that are not null.

Example

You have two legacy systems that have merged into one system. You need to concatenate the identification numbers from both systems into another system. The macro input field %ClientID% contains the following fields:
