I apologize if this is a double-post; I just got approved for the mailing list, and I can't find the older message in the archives, so I'm reposting it.
I have a table with two columns, the first with a string and the second with an integer. Given a set of input strings, I want to perform this operation 50,000+ times preferably in a single transaction: "If the string doesn't exist in the table, create a new row with the string in the first column and 1 in the second column. If the string does exist in the table, increment the second column by 1" What I am doing now is using the UPDATE statement, and checking (via C#) the number of rows affected, and if this is zero, running an insert statement. Doing this 50,000 times, without an encapsulating transaction, is an expensive operation. Is there any way to encapsulate this into SQL so that no outside interaction in C# is needed to perform this operation, and so I can put 50,000 of these into a transaction and commit all at once?
