Hi Mirco,

yes, there is! You're mixing SQL 89 and SQL 92 (I think), without
specifying JoinLinks. Change to

SQL.Strings = (
'SELECT *'
'FROM ASSAY'
'JOIN TEST ON'
'ASSAY.ASSAYID=TEST.ASSAYID'
'LEFT OUTER JOIN SAMPLETYPE'
'ON SAMPLETYPE.SAMPLETYPEID=TEST.SAMPLETYPEID)'

Don't know if this has anything to do with your problem though...
