Hi,
I was hoping fConcatChild would be the answer to my concatenation problem I
am receiving really strange results.
Here's my 1:M data (Directive-Number is in tblMaxDirective and GSWT# is in
tblGSWT):
DIRECTIVE-NUMBER GSWT#
115451 34
125061 90
125061 3
125143 51
125253 36
129069 12
129161 90
129161 37
136147 30
154981 30
166259 90
166259 31
Here's my query to concatenate:
SELECT tblMaxDirective.[DIRECTIVE-NUMBER], fConcatChild("tblGSWT","Directive-
Number","GSWT#","string",[Directive-Number]) AS GNums
FROM tblMaxDirective;
Here's the weird results I get:
DIRECTIVE-NUMBER GNums
115451 34
125061 3;90;3;90;3;90
125143 51
125253 36;36;36
129069 12
129161 37;90
136147 30
154981 30
166259 31;90;31;90;31;90;31;90
Any ideas why I am getting repeated instances of the GSWT# for Directive-
Numbers = 125061, 125253, and 166259?
I am totally stumped.
Here's my standard module code for fConcatChild:
