触发器在执行过程中遇到错误

Question

我的更新功能之一无法执行，因为下面的触发器抛出异常 ORA-2001、ORA-06512 和 ORA-04088

create or replace TRIGGER "UAM_USER"."BEFORE_UPDATE_VILLAGE" BEFORE UPDATE ON village
FOR EACH ROW
DECLARE  
    v_tbl_id  NUMBER(2);

   THEN
   RAISE user_xcep;
   END IF;

        v_tbl_id := 14;

    IF :OLD.name != :NEW.name
    THEN

END;

控制台日志：

org.springframework.jdbc.UncategorizedSQLException: PreparedStatementCallback; uncategorized SQLException for SQL [ UPDATE village   SET  name = ?       ,panchayat_id = ?       ,name_hindi = ?       ,status = ?       ,update_date = ?       ,update_by = ?       ,update_by_name = ?       ,dc_id = ?       ,loksabha_id = ?       ,census_code = ?       ,pincode = ?       ,area_type = ?

我想不通，我检查了我控制器中的所有参数，所有参数都很好，我的控制器和服务没有问题，问题在触发器之上，根据我的研发错误代码ORA-20001和ORA-06512表示列宽错误，ORA-4088表示递归更新。

更新代码：

  @Override
    public void update(Village village) {
        String q = " UPDATE village "
                + "  SET  name = :name "
//                + "      ,panchayat_id = :panchayat_id "
                + "      ,name_hindi = :name_hindi "
                + "      ,status = :status "
                + "      ,update_date = :update_date "
                + "      ,update_by = :update_by "
                + "      ,update_by_name = :update_by_name "
                + "      ,dc_id = :dc_id "
                + "      ,loksabha_id = :loksabha_id "
                + "      ,census_code = :census_code "
                + "      ,pincode = :pincode "
                + "      ,area_type = :area_type "
                + "  WHERE village_id = :village_id ";
        MapSqlParameterSource param = new MapSqlParameterSource();
        param.addValue("village_id", village.getVillageId());
        param.addValue("panchayat_id", village.getPanchayat() != null ? village.getPanchayat().getPanchayatId() : null);
        param.addValue("name", village.getName());
        param.addValue("name_hindi", village.getNameHindi());
        param.addValue("status", village.getStatus());
        param.addValue("update_date", village.getUpdateDate());
        param.addValue("update_by", village.getUserdetail() != null ? village.getUserdetail().getUserId() : null);
        param.addValue("update_by_name", village.getUserdetail().getName());
        param.addValue("dc_id", village.getDc() != null ? village.getDc().getDcId() : null);
        param.addValue("loksabha_id", village.getLoksabha() != null ? village.getLoksabha().getLoksabhaId() : null);
        param.addValue("census_code", village.getCensusCode());
        param.addValue("pincode", village.getPincode());
        param.addValue("area_type", village.getAreaType());
        getNamedParameterJdbcTemplate().update(q, param);
    }

我验证了我的列，一切正常，所以剩下的都是 ORA-04088，我无法弄清楚它在哪里以及如何递归地尝试更新表。

请帮忙

Answer 1

尝试通过包含 REFERENCING OLD AS OLD NEW AS NEW 来更改触发器声明

create or replace TRIGGER "UAM_USER"."BEFORE_UPDATE_VILLAGE" BEFORE UPDATE ON village
 REFERENCING OLD AS OLD NEW AS NEW

FOR EACH ROW

Answer 2

ORA-06512 是标准的 PL/SQL 错误，当被调用的过程（或触发器）失败时。

Ora-04088 是 Oracle 在执行触发器出现运行时错误时抛出的标准错误。

根本原因是ORA-20001错误。这在用户定义的异常范围内，瞧！您的触发器定义了一个：

PRAGMA EXCEPTION_INIT( user_xcep, -20001 );

触发器在此处引发此异常：

   IF :OLD.panchayat_id != :NEW.panchayat_id
   THEN
   RAISE user_xcep;
   END IF;

看来您的更新语句试图更改 panchayat_id 的值。最好的解决方案是从 SET 子句中删除该列：

SET  name = ?       ,panchayat_id = ?

查看您的 SpringBatch（或其他）代码，也许您应该做的是更改验证检查。也许是这样的：

   IF :OLD.panchayat_id  is null then
       null; -- allow update
   ELSIF  :NEW.panchayat_id  is null then
      :NEW.panchayat_id := :OLD.panchayat_id; -- don't wipe existing value
   ELSIF :OLD.panchayat_id != :NEW.panchayat_id
   THEN
       RAISE user_xcep;
   END IF;
