我正在尝试将CLOB
s插入数据库(请参阅相关问题)。我不太清楚怎么了。我有大约85个要插入表中的块的列表。即使只插入第一个Clob,我也会得到ORA-00911: invalid character
。我无法弄清楚PreparedStatement
在执行之前如何从语句中删除该语句,因此我不能100%地确定它是正确的,但是如果我正确,那么它应该看起来像这样:
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,该insert all
语句将包含多个into
',这就是为什么我不执行常规insert
语句的原因。我没有看到无效字符,对吗?(哦,当我在sql开发人员工具中运行该代码时,上述代码运行良好。)而且,如果我删除了中的分号PreparedStatement
,则会引发ORA-00933: SQL command not properly ended
错误。
无论如何,这是我用于执行查询的代码(以及上面示例中变量的值)。
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;
}
我有什么想念的吗?
