Question

我有一个结论Dao.java类来运行sql查询

它有

private String getCriteria(GsSrvyRepConclusion Conclusion, boolean isUpdateStatement) {
        String criteriaStatement = "";
if(Conclusion.getRecommendation() != null){
            statement += getConnectorStatement(criteriaStatement, isUpdateStatement) " CONCLUSION.recommendation =:recommendation";
        }

recomandation被定义为数据库中的CLOB数据类型。我只知道CLOB数据类型不能与＆＃34; =＆＃34;登录查询。

但当我用＆＃34;＆＃34;替换等号时，ORA-00932错误变为ORA-00927，这是缺少eqaul符号错误。

你能告诉我这个问题吗？问题可以通过使用三元运算符来解决，但我无法解决。

声明已经定义。我只需要改变;

CONCLUSION.recommendation =:recommendation

Answer 1

if(Conclusion.getRecommendation() != null){
            statement += getConnectorStatement(criteriaStatement, isUpdateStatement) " CONCLUSION.recommendation =:recommendation";
        }

应该写成

 if(Conclusion.getRecommendation() != null){
            statement += getConnectorStatement(criteriaStatement, isUpdateStatement) + ((isUpdateStatement) ? " CONCLUSION.recommendation =:recommendation " : " CONCLUSION.recommendation like :recommendation ");
        }

Java上的ORA-00932错误
