Question

I have a table

DECLARE @Results TABLE(QueryIndex smallint, FieldValue nvarchar(50))

QueryIndex is a loop counter, it will get value from @QueryIndex.
FieldValue will get value from another SQL String. For some reason, I need to execute SQL string dynamically.

SET @SQL = "SELECT " + @FieldName + " FROM MyView"
            + " WHERE Condition1='" + @Value1 + "'"
            + " AND Condition2=" + CONVERT(nvarchar(12),@Value2)

Now I try to insert data into @Results

NSERT INTO @Results(QueryIndex, FieldValue)
SELECT @QueryIndex, EXEC (@SQL)

No surprise, this code won’t work. Please provide me solution to insert data into my table. Any methods will be worth trying.
The result in table should like this:

QueryIndex   FieldName
  1            First
  2            Second
  3            Third

Thanks.

You need to combine the retrieval of @QueryIndex with the select then you can simply

SET @SQL = 'SELECT ' + cast(@QueryIndex as varchar(16)) + ',' + @FieldName + ...
INSERT INTO @Results(QueryIndex, FieldValue)
   EXEC (@SQL)
