I am not so sure that query is returning anything.

You have to give a table.column on the select when two tables are being passed in on the FROM clause.

Try adding an alias and prefixing your columns.

For Example:

str1 = "SELECT DISTINCT ts.[Sched_Code] As [No], ts.[Course], ts.[Year]........ FROM tblSchedule ts, tblCurriculum tc WHERE ts.[Subject] = tc.[Subjects]"

In database make a view of two tables first then query the view. in crystal report


The alias should match the column name you are about to show in the report.

Ex. You want Sched_Code to show inthe report from your query of 2 tables.
First put Sched_Code in the Crystal Report then make your query. Your query
should be this.

Select [ts.Sched_Code] as [Sched_Code] From ts, tblSchedule

Note: If Sched_Code doesn't appear in other tables, don't use any alias.
Crystal Report is sensitive to Column Names based on my experience on
handling it.
