SQL: Exclude record when certain field empty

[Patman]

I have probably a simple problem which is nevertheless a challenge for me:

 

The statement couloured in purple seems not to be correct. My intention is to exclude the records where Storniert_am = empty / no entry. In the report it shows null in this case. Storniert_am is a date field.

 

SELECT * from Belegung b left join Adresse a on b.Belegempfaenger = a.Nr

where Von > {d '2006-9-1'} and Storniert_am = null order by Objekt, Von

 

Thanks for your help!

 

By the way: Is there somewhere a repository of examples of SQL statements for iReport which I can use as templates?

You might want to try Storniert_am is null.

 

HTH,
