Hi,

Here is a scenario to reproduce this bug :

Add a TmyQuery , name it master.
Fill the SQL property.
Add a Datasource and link it to the master query.
Left Click on the master Query , select field editor and retreive all fields (CTRL L)

Add a TmyQuery, name it Details
Fill the SQL property with a where clauses having 3 or 4 conditions
Add a Datasource and link it to the details query.
Left Click on the details Query , select field editor and retreive all fields (CTRL L)
Fill the MasterSource property
Fill the Master / Design key

That will works fine.

Now modify the SQL statement from the Details Query. Just remove the where clauses.
Try to activate the query : you will get an mysql error : #4200 you have an error in your SQL syntax... check you sql query near '?' at line xx

This error also happens when modifying an order by clause....

The solution to "bypass" this is to clear the Master/Detail key and then add the new persistent field...

Can anybody else test this ?
Thanks...
