我的无效字符在哪里 (ORA-00911)
2022-08-31 14:17:12
我正在尝试将 s 插入到数据库中(请参阅相关问题)。我不太清楚出了什么问题。我有一个列表,其中包含要插入到表中的大约85个clob。即使只插入第一个 clob,我也会得到 .我无法弄清楚如何在语句执行之前将其取出,因此我无法100%确定它是正确的,但是如果我做对了,那么它应该看起来像这样:CLOB
ORA-00911: invalid character
PreparedStatement
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,这个插入所有
语句会有很多's,这就是为什么我只是不做一个常规语句。我没有看到一个无效的字符,对吧?(哦,当我在我的sql开发人员工具中运行它时,上面的代码运行良好。如果我去掉中的分号,就会抛出一个错误。into
insert
PreparedStatement
ORA-00933: SQL command not properly ended
无论如何,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;
}
}
ResultSet rs = pstmt.executeQuery(); //Obviously, this is where the error is thrown
conn.commit();
ConnectionPool.getInstance().release(conn);
return rs;
}
有什么是我刚刚错过了很多时间吗?
