I have a MSSQL Database, and I have a stored procedure for any possible query, most of them just return a row of data with 3 columns or just execute an INSERT
How in java to connect to the DB and execute a stored procedure, and retrieve some data ?
A connection pool like DBCP makes a big difference. The connection time can be save this way.
Prepared statements can help the database to skip query parsing. The parsed statements will be cached.
Batch updates help when you’re executing a statement repeatedly.
Setting the right fetch size is another optimization for queries.
