----------------------------------------------------------- From: Iamtheoneurwarnedabout Message 1 in Discussion Hi All, Iam working on a tool in C#. This tool imports the data(.csv, .txt, .xls, .dmp) from third party sources, and stores in appropriate table schemas based on whether the data/record is unique or not. For that Iam implementing following logic: (correct me if Iam wrong) Iam reading record by record from a file (say .csv) and comparing with existing table (say tableA), if the record is found to be existing I need to insert the whole record in another tableB (where all duplicate records are maintained) if not I need to insert in tableA. Note: The files(.csv or .txt or .xls) which Iam reading does not have any unique field/column. So, Iam comparing the record in a file with that of tableA on Firstname, Lastname and Address. Iam writing a stored proc and cursor for this to enhance performance. Stored Procedures consists of 3 SQL statements (One SELECT and Two INSERT statements). Cursor for SELECT statement (Iam using indexes for FirstName, Lastname and Address) Is there any better alternative to this? Please suggest/advice me whether the above logic is good enough keeping in mind the performance issue (Remember the Data importing will be in a tune of MB's ) Awaiting for your suggestions.
