|
|
- The CallableStatement extends the PreparedStatement interface.
- The CallableStatement provides an interface for calling database stored procedures.
|
the simplest form of this syntax would be: |
|
|
which represents a call to a stored procedure with no parameters.
A call to a stored procedure accepting two input parameters: |
|
{call procedure-name (?, ?)}
CallableStatement callproc = connection.prepareCall("{call updateLast (?, ?)}");
callproc.setInt (1, 5); // 1 specifies the first parameter
callproc.setString (2, "J"); // 2 specifies the second parameter
|
|
To now execute the stored procedure, we use the following statement: |
|
callproc.executeUpdate();
