为什么sql命令没有正确结束被抛出？

Question

我正在使用嵌入在Java中的SQL运行查询。我的数据库中有三个表格，QUERY，G1和G2。它们都具有相同的（SETID，GENEID）模式。

我运行的查询如下：

SELECT q.SETID, COUNT(q.SETID), g1.SETID, COUNT(g1.SETID) 
FROM QUERY AS q 
INNER JOIN G1 AS g1 ON q.GENEID = g1.GENEID 
GROUP BY q.SETID, g1.SETID 

执行的部分代码：

DriverManager.registerDriver(new oracle.jdbc.OracleDriver()); 
con = DriverManager.getConnection(url, user, password); 
stmt = con.createStatement(); 
String sql = "SELECT q.SETID, COUNT(q.SETID) AS QSIZE, g1.SETID, COUNT(g1.SETID) AS GSIZE FROM QUERY AS q INNER JOIN G1 AS g1 ON q.GENEID = g1.GENEID GROUP BY q.SETID, g1.SETID"; 
rs = stmt.executeQuery(sql); 
rsmd = rs.getMetaData(); 

当我运行它，它会引发以下错误： ORA-00933：SQL命令没有妥善结束。任何人都可以请帮我解决这个错误？

谢谢！

Answer 1

尝试：

1. 逃生表名QUERY - 它看起来像保留字
2. 添加别名COUNT（）列 - 例如COUNT(q.SETID) as Q_CNT
3. 末
4. 添加分号删除表格别名，如@harvey建议

SELECT q.SETID, COUNT(q.SETID) as Q_CNT, g1.SETID, COUNT(g1.SETID) as G1_CNT 
FROM `QUERY` AS q 
INNER JOIN G1 AS g1 ON q.GENEID = g1.GENEID 
GROUP BY q.SETID, g1.SETID; 

---

SELECT QUERY.SETID, COUNT(QUERY.SETID) as Q_CNT, G1.SETID, COUNT(G1.SETID) as G1_CNT 
FROM QUERY 
INNER JOIN G1 ON QUERY.GENEID = G1.GENEID 
GROUP BY QUERY.SETID, G1.SETID;
