Hello all, I have an Access 2003 database . That database contains around 60,000 rows of data dealing with their vendor data such as total TargetWeight, ActualWeight , etc... I'm collecting data from this database to populate mt gridview in c#which I can later develope a Summary report of sorts showing average TargetWeight, AVG(ActualWeight)and other info grouped by the ID . Easy enough right?
Query works fine in Access ,but in c# I keep getting error like am using a reserved word, And in fact I have tried all the Aggregate Function in my query from c# to Access DB ,but failed up to this point, help me if am missing something thanks.

command.CommandText = " SELECT t1.IngredientLotId1, t1.IngredientName, t1.ActualWeight, t1.TargetWeight, ROUND((t1.ActualWeight- t1.TargetWeight ),0)AS VARIANCE,ROUND( (0.04* t1.TargetWeight ),0)AS TOLERANCE,ROUND(([t1].[TargetWeight]),0),AVG(t1.TargetWeight) AS AvgTargetWeight FROM CompletedIngredients As t1 INNER JOIN CompletedFormulas As t2 ON t1.RecordNumber=t2.RecordNumber ORDER BY t2.StartTime ASC;

Check the list of reserved words: http://support.microsoft.com/en-us/kb/286335
Note, when you're using aggregate function (such as AVG), you need to group data: http://www.blueclaw-db.com/accessquerysql/sql_aggregate_function.htm

There is a comma that should not be here just before your FROM statement.

As i mentioned in comment to the question, one possible reason that your query does not work is that you forgot to add GROUP BY clause together with AVG() function. Finall query should look like:

SQL

SELECT t1.IngredientLotId1, t1.IngredientName, t1.ActualWeight, t1.TargetWeight, ROUND((t1.ActualWeight- t1.TargetWeight ),0) AS VARIANCE,
    ROUND( (0.04* t1.TargetWeight ),0) AS TOLERANCE, ROUND(([t1].[TargetWeight]),0) AS TargetWeight, AVG(t1.TargetWeight) AS AvgTargetWeight
FROM CompletedIngredients As t1 INNER JOIN CompletedFormulas As t2 ON t1.RecordNumber=t2.RecordNumber
GROUP BY t1.IngredientLotId1, t1.IngredientName, t1.ActualWeight
-- ORDER  BY t2.StartTime ASC;
