Question

I’m using Enterprise library, but the idea is the same. I have a SqlStringCommand and the sql

is constructed using StringBuilder in the forms of

"insert into table (column1, column2, column3) values (@param1-X, @param2-X, @parm3-X)"+" " 

where “X” represents a “for loop” about 700 rows

StringBuilder sb = new StringBuilder();
for(int i=0; i<700; i++)
{
   sb.Append("insert into table (column1, column2, column3) values (@param1-"+i+", @param2-"+i, +",@parm3-"+i+") " );
}

followed by constructing a command object injecting all the parameters w/ values into it.

Essentially, 700 rows with 3 parameters, I ended up with 2100 parameters for this “one sql” Statement.

It ran fine for about a few days and suddenly I got this error

===============================================================

A severe error occurred on the current command. The results, if any, should be discarded.

Any pointers are greatly appreciated.

Not sure, but check this out: Hitting the 2100 parameter limit (SQL Server) when using Contains()
