IBM Report Builder issue with enumeration list in DNG and LISTAGG

Krzysztof Koprowski (1017) | asked May 11 '20, 12:42 p.m.

I have issue with LISTAGG function in Report Builder when generating reports from DNG.

Requirements has enum list that can have values from 1 to 10, so one requirement can have for example 1,5 and 6.

When we will execute report with LISTAGG using this attribute we are getting 1,1,1,5,5,5,6,6,6.

Each selected value is displayed 3 times.

Can You help us to make each value to appear once like it should be 1,5,6.

 Hi Krzysztof,

If you want to get rid of duplicates, you should use distinct function other with listagg. I do not know what database are you using but for DB2 it should look like "LISTAGG(DISTINCT T4.LITERAL_NAME,',') AS LITERAL_NAME".

Additionally, if this query wont validate because it will be too complex for Report Builder to validate then You can turn off the validation.
