Next I put a SQLDataset (same with SQLQuery) with the sentence select * from orders and another SQLDataset with select * from [order details] where OrderID=:OrderID then I put a Datasource referencing SQLDataset1, and select the datasource in SQLDataset2 (property Datasource). I thought that second dataset would take the parameter from the field with the same name in SQLDataset1. But I only get a message SQL Server error: SQL State: HY000, SQL Error Code: 0 (null) I can't get through that. As a result, I am unable to work with nested datasets... I guess this have to do with a problem with parameters i have posted before (no answers): sometimes, many times but not always, i am unable to open a query like select * from table where id=:aParam where Table is a valid table and id is the name of the primary key field. Does anybody have experienced the same problem? I can't believe i am the only one using parameters with sqlserver! P.S: both problems get away using Core Labs' driver (trial)... Thanks in advance Ernesto Cullen Back to top Jan Doggen Guest Posted: Mon Aug 30, 2004 8:57 am    Post subject: Re: I can't do nested datasets with sqlserver Hello Ernesto 1) Use the database form wizard in Delphi to set up a master/detail relationship, then compare your code with the code generated by the wizard (its under File/New/Other/Business) 2) Do you use the latest DBExpress MSSQL driver (there has been an update)? 3) What Delphi versions?

I have found an entry in QC (#3689) talking about the error with a single query (not nested), which I have found too. And a comment from Ramesh Theivendran says that it is a MS bug (case #SRX030738605044) and they are inventigating for a workaround. Later I found another Ramesh post where he says the error is addressed in D8 driver, and there are plans to port the fix back to D7... the question is 'when'. This error (mainly the one-table error) is causing me a lot of trouble, and I can't wait to Borland. I'll swith to CoreLabs driver Thanks for your attention Jan Ernesto Cullen Jan Doggen wrote: Quote: Hi Ernesto Additional: - The full error message you get (I think) adds "invalid input parameter message".
