oracle存储过程中简单地调用另一个有返回值的存储过程

先建一张测试表：

create table WWT_TABLE_TEST
(
  NAME     VARCHAR2(2000),
  AGE      NUMBER,
  SEX      VARCHAR2(20),
  BIRTHDAY DATE
)

 创建被调用的存储过程：

create or replace procedure wwt_test2(inchar in varchar2,outchar out varchar2) is
begin
outchar:=inchar||'hello procedure';
end;

 

创建调用被调用存储过程的存储过程：

create or replace procedure wwt_test1  is
myString varchar(1000);
tempString varchar(1000);
sqlText varchar(1000);
record_number number;
logId NUMBER;--记录log_pro的id
begin
--select cooper.SEQ_LOG_PRO.NEXTVAL into logId from dual;
begin

tempString:='already';
wwt_test2('wwt',tempString);
myString:=tempString;
sqlText:='insert into wwt_table_test  values('''||myString||''')';
dbms_output.put_line('==>'||sqlText);
execute immediate 'insert into wwt_table_test(name)  values('''||myString||''')';
execute immediate 'update wwt_table_test set name = name||''hello''';
commit;
end;
--以下为其它测试之用，可忽略
select count(*) into record_number from
 tbl_importdata_log t where t.STATE=1 and t.begintime like to_char(sysdate-2,'yyyy-mm-dd')||'%';
Dbms_Output.put_line('==>'||record_number);
if record_number<67 then
update wwt_table_test set name ='更新失败',age=23;
end if;
if record_number = 67 then
update wwt_table_test set name ='更新成功',age=24,birthday=sysdate;
end if;
commit;

end;

   

创建完后，在命令窗口中：call wwt_test1();执行完毕后，在表wwt_table_test中就会有一条记录了。

也可以在java类中调用，如：

package procudure;

import java.sql.CallableStatement;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

public class ProcedureTest {
	public static void main(String[] args) {
		try {
			Class.forName("oracle.jdbc.driver.OracleDriver");
			Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@127.0.0.1:1521:JULY", "scott","snaillocke");
			CallableStatement cs = conn.prepareCall("{call wwt_test1()}");
			/*
			 * 如果有参数可以在此设置
			 */
			//cs.setString(1, "SCOTT");
			//cs.setDouble(2, 666.66);//如果有是回值：call.registerOutParameter(2, java.sql.Types.VARCHAR);call.execute(); 
        			//String testPrint = call.getString(2);
			cs.execute();
			cs.close();
			conn.close();
		} catch (ClassNotFoundException e) {
			e.printStackTrace();
		} catch (SQLException e) {
			e.printStackTrace();
		}
		
	}
}
