The JDBC CallableStatement is used to execute the store procedure and functions. Let us study JDBC CallableStatement by batch update example. Example: insertEMPLOYEE Procedure JDBC CallableStatement Stored procedure IN parameter example. CREATE OR REPLACE PROCEDURE insertEMPLOYEE( e_id IN EMPLOYEE.EMPLOYEE_ID%TYPE, e_name IN EMPLOYEE.NAME%TYPE, e_salary IN EMPLOYEE.SALARY%TYPE) IS BEGIN   INSERT INTO EMPLOYEE ("EMPLOYEE_ID", "NAME", "SALARY") VALUES … Read more

The JDBC CallableStatement is used to execute the store procedure and functions. Let us study JDBC CallableStatement by OUT parameter example. Example: getEmpNameByEmpId Procedure JDBC CallableStatement Stored procedure IN parameter example. CREATE OR REPLACE PROCEDURE getEmpNameByEmpId( e_id IN EMPLOYEE.EMPLOYEE_ID%TYPE, e_NAME OUT EMPLOYEE.NAME%TYPE) IS BEGIN   SELECT NAME INTO e_NAME FROM EMPLOYEE WHERE EMPLOYEE_ID = e_id; … Read more

The JDBC CallableStatement is used to execute the store procedure and functions. CallableStatement interface provides the methods to execute the store procedure and functions. We can get a statement object by invoking the prepareCall() method of Connection interface. Syntax: CallableStatement callableStatement = conn.prepareCall(“{call procedurename(?,?…?)}”);  Note: A store procedure is used to perform business logic and … Read more

The JDBC PreparedStatement is used to execute parameterized queries against the database. Let us study JDBC PreparedStatement by batch update example. Example: JDBCTest.java import java.sql.Connection; import java.sql.PreparedStatement; import com.w3schools.util.JDBCUtil;   /** * This class is used to batch update in DB table * using PreparedStatement. * @author w3schools */ public class JDBCTest { public static … Read more
