ORACLE存储过程的创建

1.无返回值

CREATE OR REPLACE PROCEDURE TESTA(paramA IN VARCHAR2,paramB in VARCHAR2)AS
 BEGIN
 INSERT INTO TNAME (T_id,T_name)values(paramA,paramB);
 END TESTA;
 

java调用代码：

CallableStatement proc = null;
proc = conn.prepareCall("{ call TESTA(?,?) }");
proc.setString(1, "100");
proc.setString(2, "TestOne");
proc.execute();

2.有返回值

 CREATE OR REPLACE PROCEDURE TESTB(PARA1 IN VARCHAR2,PARA2 OUT VARCHAR2) AS
 BEGIN
 SELECT INTO PARA2 FROM TNAME WHERE I_ID= PARA1;
 END TESTB；
 

java调用代码：

CallableStatement proc = null;
proc = conn.prepareCall("{ call TESTB(?,?) }");
proc.setString(1, "100");
proc.registerOutParameter(2, Types.VARCHAR);
proc.execute();
String testPrint = proc.getString(2);

3.返回列表

 --建一个程序包
 CREATE OR REPLACE PACKAGE TESTPACKAGE AS
 TYPE Test_CURSOR IS REF CURSOR;
 end TESTPACKAGE;
 --建立存储过程，存储过程为：
 CREATE OR REPLACE PROCEDURE TESTC(p_CURSOR out TESTPACKAGE.Test_CURSOR) AS
 BEGIN
 OPEN p_CURSOR FOR SELECT * FROM TNAME;
 END TESTC;
 

java调用代码：

CallableStatement proc = null;
proc = conn.prepareCall("{ call testc(?) }");
proc.registerOutParameter(1,oracle.jdbc.OracleTypes.CURSOR);
proc.execute();
rs = (ResultSet)proc.getObject(1);
