Left join many to many not working as expected

Anonymous — Thu, 15 Jun 2017 21:17:42 GMT

Hi All,

Trying to join FROM a table where the join key is repeated to another table where the join key is repeated. I expect to have rows added to the target table for every matching row in the joining table. However, it seems that if there is only one distinct join key value in the joining table, it only joins once per line in the target table; no rows are added. Please help if you can!

Might be better explained with an example:

LOAD * INLINE [

Name, Value

John, .5

John, .2 ];

Left Join(A)

LOAD * INLINE [

Name, Value2

John,10

John,20 ];

Expected Output:

Name, Value, Value2

John, .5, 10

John, .5, 20

John, .2, 10

John, .2, 20

Actual Output:

John, .5, 10

John, .2, 20

You're doing it right. When I run your code, it gives me the expected output. I didn't change your code at all.

Strange! Could it be a version issue? I'm using v12 SR1.

I'll update to a newer SR and report back.

It was a bug in QV12 SR 1

Left join broken in QlikView 12 SR1?

YEP! Updated to SR5 and it's now working as expected.

Thanks, David
