Solution 2

You have not given the alias name of "document" Table .
Modify the query by this way

Select documentid,title from document a inner join Company b on a.companyid = b.companyid where b.ParentCompanyId = 428

Thanks

Solution 3

You have missed the table alias 'a' in the joining.
Try this-

C#

DsLoginData = SqlHelper.SqlHelper.ExecuteDataset(conn, CommandType.Text, "Select documentid,title from document a inner join Company b on a.companyid = b.companyid where b.ParentCompanyId = 428  ");

Hope, it helps :)

Solution 1

You forgot to define a
Change

SQL

"Select documentid,title from document inner join Company b on a.companyid = b.companyid where b.ParentCompanyId = 428 "

To

SQL

"Select documentid,title from document a inner join Company b on a.companyid = b.companyid where b.ParentCompanyId = 428 "
