SqlDataTable.Open Exceptoin

[tharollas]

Hi,
I have below code that does select statement which works in Management Studio,
but when I try to call SqlDataTable.Open method I get an exception.
I'm using VS2012 Update 2, with dcsqlserver260pro build 719

//cmdSelectQAGenFims_Detail is SqlCommand
cmdSelectQAGenFims_Detail.CommandText = "select a.* from erms.vwqa_genfilm_eval a where ((a.chiefclassifier_personid in(" + _personID + ")) or (a.qa_evaluator_personid in(" + _personID + ")) or (a.classifier1_personid in(" + _personID + ")) or (a.classifier2_personid in(" + _personID + ")))";
tblQAAdultFilms_Detail.SelectCommand = cmdSelectQAGenFims_Detail;
tblQAGenFims_Detail.Open();//SqlDataTable

SQL PRODUCED Works in SQL Server Management Studio
select a.* from erms.vwqa_genfilm_eval a where ((a.chiefclassifier_personid in(1)) or (a.qa_evaluator_personid in(1)) or (a.classifier1_personid in(1)) or (a.classifier2_personid in(1)))

EXCETION is after tblQAGenFims_Detail.Open();

Resolved.

Connection was pointing to the wrong database that did not have changes.
