Thank you really.
In my case, I have to insert the rows to table one by one.
For the connection pooling, I got the information from the User Guide.
The FreeTDS connection pool currently only supports TDS version 4.2.
If FreeTDS 1.0 supports protocol 7.2 with some limitations, where can I find the
limitation's description, so that I can identify if it will affect my case.
BTW, is there any sample code for connection pooling?
Thanks in advance

It's not clear if the problem is application or connections.
If you have one application that needs to insert rows into a table
it's better to batch the inserts instead of using a query for each
If you have multiple process each needing to connect to database and
insert a row then would be better to use a connection pooling. The
connection pooling included in FreeTDS 1.0 supports protocol 7.2 with
