Question

I’m dealing with chunks of data that are 50k rows each.
I’m inserting them into an SQL database using LINQ:

for(int i=0;i<50000;i++)
{
    DB.TableName.InsertOnSubmit
    (
        new TableName
        {
            Value1 = Array[i,0],
            Value2 = Array[i,1]
        }
    );
}
DB.SubmitChanges();

This takes about 6 minutes, and I want it to take much less if possible. Any suggestions?

Answer 1

if you are reading in a file you’d be better off using BULK INSERT (Transact-SQL) and if you are writing that much (50K rows) at one time from memory, you might be better off writing to a flat file first and then using Bulk Insert on that file.
