Name

AgConcat

Purpose

Concatenate values, with aggregation.

Description

Returns the concatenation of each of the argument values.

To separate each element in the concatenation with a delimiter, double-click the AgConcat function in the Value tab and specify the delimiter to use.

Since this is an aggregate function, each argument is subject to different looping than that of the enclosing expression. See Aggregate Looping for details on how this looping works.

If you wish to perform additional computation in conjunction with this aggregate function (a sum for example), then do that in an enclosing expression that uses this aggregate function as an argument.
