View 8 RepliesI have a multi- statement transcation in my stored procedure, that is either inserting or updating records in table1 and table2.
table1 has a check constraint. Will the check constraint be checked only after I call COMMIT in above transaction, OR will it be checked before I call COMMIT when using INSERT or UPDATE statement?
is there a SQL statment i could write that would sum each column and allow me to then access each sum individually
i.e
Dim objCmd As New OleDb.OleDbCommand("SELECT SUM(expression) FROM orderForm WHERE OrderDate=@OrderDate", objConn)
is there anything i can replace expression with such that all the columns in orderForm could be summed and returned as one record
or is there a way to replace expression with something that would allow me to just keep changing the paramater so i could continuously reexectute the same command w/o having to create a new command for each column

This question is for wrapping up work on a database driven AJAX AutoComplete Control that I am using to provide keyword hints to user on search pages. Each record has 6 columns for keywords where each column is for an advertiser to add a keyword. These are used in meta keywords tags, but I also want to use them for AutoComplete. The problem is that I don't know how to write a SELECT statement in Visual Studio that treats all 6 keyword columns as if they were all one column. I am looking for something like
SELECT (keyword1 + keyword2 + keyword3) AS Keywords
FROM (Merchandise)
WHERE Keywords LIKE @term
