        I'm so used to writing:

        SELECT * FROM [table name]

        That you can bet when it's time to delete I'll write:

        DELETE * FROM [table name]

        I no longer blame myself. I consider it a language design bug thingy.

        Personally I use extension methods when writing LINQ, not the SQL like syntax. Anytime I see the SQL syntax my mind goes blank.

          But it's not really a 'bug thingy': You can select * (meaning all) or columns you name when selecting. When you Delete, it's the whole ROW, not columns, hence the */Column names aren't required. :-)

              Which is why I have replaced that with

              SELECT COUNT(ROWID) FROM [table_name]

              Sometimes that by itself will tell me all I need to know. :)

                        If get in the habit of putting all your statements inside a transaction, then if you realize you made a mistake you can roll it back without affecting the table. Of course, you have to remember to commit the transaction in a timely manner, otherwise the table remains locked.

                          I've found a very easy way to completely avoid making any mistakes in SQL: I don't use SQL.

                          You're lucky man.  I often wake up in a cold sweat in the middle of the night wondering if I left out the WHERE clause when executing a DELETE. :sigh: /ravi

                            Solid advice but the ONLY time I ever use the delete command is to clear test database tables. I never use delete in production - everything is a log and if the user doesn't want to see it anymore a flag is set on the record. I was getting burned too often by people who would blame me for bad data. Every item and every change is logged and nothing is ever deleted. :^)

                            Agreed, solid advice, but cloud storage (my company is in Azure now) makes soft deletes expensive. What we've started doing is setting soft deletes on large blobs, then purging those older than 90 days every month or so; if they don't notice it in 90 days, then YAGNI :)

                                I like doing SELECT COUNT(*) or just SELECT *, making sure my results are valid, then changing it to DELETE. Seems to work for me.

                                      I also do that. I think it's a bad habit I picked up with Access, because if I recall correctly, you had to say it like that in Access SQL.

                                        Having written code for databases that didn't have it I would certainly call it advanced.

                                          Personally I use extension methods when writing LINQ, not the SQL like syntax. Anytime I see the SQL syntax my mind goes blank.

                                          I am just the opposite, being new to LINQ...putting the from before the select just seems weird...and I still can't get it to accept more than one orderby param! :confused:
