哪里是我的无效角色(ORA-00911)
我正在尝试将CLOB
s插入数据库(请参阅相关问题)。我无法弄清楚出了什么问题。我有一个大约85个clobs的列表,我想插入表中。即使只插入我得到的第一个clob ORA-00911: invalid character
。我无法弄清楚如何PreparedStatement
在执行之前获取声明,因此我无法100%确定它是正确的,但如果我做对了,那么它看起来应该是这样的:
insert all into domo_queries values ('select substr(to_char(max_data),1,4) as year, substr(to_char(max_data),5,6) as month, max_data from dss_fin_user.acq_dashboard_src_load_success where source = ''CHQ PeopleSoft FS''')select * from dual;
最终,这个insert all
陈述会有很多into
,这就是我不做常规insert
陈述的原因。我没有在那里看到无效的角色,对吗?(哦,当我在我的sql开发人员工具中运行它时,上面的代码运行正常。)如果我删除了分号PreparedStatement
,它会抛出ORA-00933: SQL command not properly ended
错误。
在任何情况下,这是我执行查询的代码(以及上面示例的变量值)。
public ResultSet executeQuery(String connection, String query, QueryParameter... params) throws DataException, SQLException { // query at this point = "insert all //into domo_queries values (?) //select * from dual;" Connection conn = ConnectionPool.getInstance().get(connection); PreparedStatement pstmt = conn.prepareStatement(query); for (int i = 1; i <= params.length; i++) { QueryParameter param = params[i - 1]; switch (param.getType()) { //The type in the example is QueryParameter.CLOB case QueryParameter.CLOB: Clob clob = CLOB.createTemporary(conn, false, oracle.sql.CLOB.DURATION_SESSION); clob.setString(i, "'" + param.getValue() + "'"); //the value of param.getValue() at this point is: /* * select * substr(to_char(max_data),1,4) as year, * substr(to_char(max_data),5,6) as month, * max_data * from dss_fin_user.acq_dashboard_src_load_success * where source = ''CHQ PeopleSoft FS'' */ pstmt.setClob(i, clob); break; case QueryParameter.STRING: pstmt.setString(i, "'" + param.getValue() + "'"); break; } }
有什么我只是错过了很多时间吗?
