Question

我试图通过JDBC在Oracle DB中执行以下查询，但它抛出异常。例外是：

java.sql.SQLException: ORA-00933: SQL command not properly ended

请建议需要更改的内容？

String questionQuery = "SELECT PCN_SURVEY_DEFINITION.ID, PCN_SURVEY_DEFINITION.NAME, PCN_QUESTIONS.ID, PCN_QUESTIONS.SURVEY_ID, PCN_QUESTIONS.LABEL, "
                + "PCN_QUESTIONS.TYPE, PCN_QUESTIONS.REQUIRED, PCN_QUESTIONS.COMMENTS, PCN_QUESTIONS.DISPLAY_ORDER "
                + "FROM PCN_SURVEY_DEFINITION, PCN_QUESTIONS "
                + "WHERE PCN_SURVEY_DEFINITION.ID = PCN_QUESTIONS.SURVEY_ID "
                + "AND PCN_SURVEY_DEFINITION.NAME=? "
                + "ORDER BY PCN_QUESTIONS.DISPLAY_ORDER ASC";

Answer 1

What do you do with the question mark? Maybe you meant to put a column name here of the other table? The one before the ORDER BY? Or are you using a prepared statement afterwards? Try removing this condition temporarily for testing purposes: "AND PCN_SURVEY_DEFINITION.NAME=? "

 "WHERE PCN_SURVEY_DEFINITION.ID = PCN_QUESTIONS.SURVEY_ID " + "AND PCN_SURVEY_DEFINITION.NAME=? " + "ORDER BY

Answer 2

更正WHERE子句中的条件并正确检查引号（“）从哪里开始以及在哪里结束。

"WHERE PCN_SURVEY_DEFINITION.ID = " + PCN_QUESTIONS.SURVEY_ID + " AND PCN_SURVEY_DEFINITION.NAME=? " + "ORDER BY PCN_QUESTIONS.DISPLAY_ORDER ASC";

Answer 3

Oracle不支持问号＆＃34;？＆＃34;。对于变量绑定oracle使用＆＃34;：name＆＃34;或＆＃34;：1＆＃34;

Answer 4

我有类似的东西，不得不在我的application.properties文件中添加以下属性（因为我使用的是Spring Boot），这解决了我的问题而无需更改任何SQL

spring.jpa.database=oracle

JDBC - java.sql.SQLException：ORA-00933：SQL命令未正确结束
