Try this --
SELECT *, "TodBefore10" AS qry_Source FROM [qryTodBefore10]
UNION
SELECT *, "Tod10To12" FROM [qryTod10To12]
UNION
SELECT *, "Tod12To2" FROM [qryTod12To2]
UNION
SELECT *, "TodAfter2" FROM [qryTodAfter2];

I have created a union query and now want to create a field alias to specify
which records come from which query.
The union query works as such:
SELECT * FROM [qryTodBefore10]
UNION
SELECT * FROM [qryTod10To12]
UNION
SELECT * FROM [qryTod12To2]
UNION
SELECT * FROM [qryTodAfter2];


But when I try to add the field alias I get the error: Syntax Error in From
clause. The error is not any more specific than that. I have tried so many
different statements I thought it may be better to just ask: What is the
correct syntax to add a field alias called [TimeOfDay]?

Thanks.
