Generate insert SQL statements from a CSV file

It's a bit crude - but for one off jobs, I sometimes use Excel.

If you import the CSV file into Excel, you can create a formula which creates an INSERT statement by using string concatenation in the formula. So - if your CSV file has 3 columns that appear in columns A, B, and C in Excel, you could write a formula like...

="INSERT INTO MyTable (Col1, Col2, Col3) VALUES (" & A1 & ", " & B1 & ", " & C1 & ")"

Then you can replicate the formula down all of your rows, and copy, and paste the answer into a text file to run against your database.

Like I say - it's crude - but it can be quite a 'quick and dirty' way of getting a job done!

Well, if it's a CSV, and it this is a one time process, open up the file in Excel, and then write formulas to populate your data in any way you desire, and then write a simple Concat formula to construct your SQL, and then copy that formula for every row. You will get a large number of SQL statements which you can execute anywhere you want.

Fabio,

I've done what Vaibhav has done many times, and it's a good "quick and dirty" way to get data into a database.

If you need to do this a few times, or on some type of schedule, then a more reliable way is to load the CSV data "as-is" into a work table (i.e customer_dataload) and then use standard SQL statements to populate the missing fields.

(I don't know Firebird syntax - but something like...)

UPDATE personSET id = (SELECT newguid() FROM createguid)UPDATE personSET cityid = (SELECT cityid FROM cities WHERE person.cityname = cities.cityname)

etc.

Usually, it's much faster (and more reliable) to get the data INTO the database and then fix the data than to try to fix the data during the upload. You also get the benefit of transactions to allow you to ROLLBACK if it does not work!!
