Examples of java.sql.Connection.prepareCall()

java.sql.Connection.prepareCall()
A SQL stored procedure call statement is handled by creating a CallableStatement for it. The CallableStatement provides methods for setting up its IN and OUT parameters, and methods for executing it.
Note: This method is optimized for handling stored procedure call statements. Some drivers may send the call statement to the database when the prepareCall is done; others may wait until the CallableStatement is executed. This has no direct affect on users; however, it does affect which method throws certain SQLExceptions. @param sql a SQL statement that may contain one or more '?'parameter placeholders. Typically this statement is a JDBC function call escape string. @return a new CallableStatement object containing thepre-compiled SQL statement @exception SQLException if a database-access error occurs.
