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

Question

我试图通过 JDBC 在 Oracle DB 中执行以下查询，但它抛出异常。异常(exception)是:

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

请建议需要更改哪些内容？

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

更正 WHERE 子句中的条件并正确检查引号 (") 的起始位置和结束位置。

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