I normally place all db related work in my databases in SQL Server Express 2005. But in tutorials I have seen, I heard that one needs to re-create referential integrity and relationships and constraints and checks and defaults anew in datasources mapped onto databases.

I have a program that goes through SQL statements, identifying component parts with a space. eg: -
SELECT * FROM tblSales WHERE CustomerID=10 AND Year=2011
Would produce the following as separate components: -
"SELECT","*","FROM","tblSales","WHERE","CustomerID=10","AND" and "Year=2011"
The problem I have however is the use of spaces within values eg.:-
SELECT * FROM tblSales WHERE CustomerNameID='Test Company' AND Year=2011
Using the same space-separating logic, this would produce components of:

continuing on from my original post about datagridview.... [URL]
is there any working examples of implementing add/update/delete using the binding source?
i have a datagridview that has a bindingsource as its datasource and i am wanting to provide Add/Update/Delete functionality on the grid itself. Each record has a delete button which when clicked will remove the row and then add/edit is performed in the grid itself
the user then clicks a save/commit button that will then perform the nessecary updates on all rows
my initial plan was to have a copy of the data (iList) and then compare this to the contents of the binding source data to confirm whether to add/update or delete the record
also upon clicking the delete button i cant get it to remove the row from the datagridview. it thought i could do something like this...
