存储过程项目实战

数据库脚本（注意if  end if 这种格式）

create or replace package body pmp_agnt_public_pkg as

   PROCEDURE fix_contract (p_agreement_no VARCHAR2,   -- 入参
                           p_error OUT VARCHAR2) AS   -- 出参
       v_agreement_id number; -- 声明变量
       .......
       BEGIN;
            SELECT COUNT(*) INTO v_cnt03 FROM TSE_AGREEMENT_INFO_NEW t WHERE t.bussiness_type = '422' AND t.agreemen_no = p_agreement_no;
            IF v_cnt03 = 0 THEN 
               p_error := '你所输的不是区域代理合同编号，请确认后再输';   -- 返回值
               RETURN;
            END IF;
            ...........
       END;
   END fix_contract;   

end pmp_agnt_public_pkg;

xml文件：注意jdbcType=VARCHAR，被狠狠坑了一嗲

<update id="fixContract" statementType="CALLABLE">
      {call pmp_agnt_public_pkg.fix_contract(#{p_agreement_no,mode=IN,jdbcType=VARCHAR},#{p_error,mode=OUT,jdbcType=VARCHAR})}
</update>

怎么调用xml：入参用map封装，出参用map.get("");

public String fixContract(String agreementNo) {
    Map<String, String> map = new HashMap<String, String>();
    map.put("p_agreement_no", agreementNo);    
    dao.update("fixContract", map);
    return map.get("p_error");   
}

END!
