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

Hobbyist here, Is it normal for businesses to be having 50 mil rows to insert into a 50 columns wide database via a 2100+ parameters query, 15000 inserts at a time to a single DB?

Inserting 15k rows of 50 columns into a 50M table is something we do every day.

2100 params on a query sounds like spaghetti code.

I suspect OP is using single row insert statements when they need a bulk insert to be performant.

I am using SqlBulkInsert, given how bad MS is with naming things, that might as well be row inserts instead of bulks
