Omg it’s sooo daammmn slooow it takes around 30 seconds to bulk - insert 15000 rows

Disabling indices doesn’t help. Database log is at SIMPLE. My table is 50 columns wide, and from what i understand the main reason is the stupid limit of 2100 parameters in query in ODBC driver. I am using the . NET SqlBulkCopy. I only open the connection + transaction once per ~15000 inserts

I have 50 millions rows to insert, it takes literally days, please send help, i can fucking write with a pen and paper faster than damned Microsoft driver inserts rows

    One thing to know about transactions is that they track data and then write it. It’s not the opening that slows it down. I have a question though, what is your source data? Do you have a big CSV for something? Can you do a db to db transfer instead? There’s another tool called the BCP utility.

    Edit: SQL server/ssms have tools for doing migrations and batch imports
