我的查询
String sql = "SELECT COLUMN1 AS 'ALIAS1', COLUMN2 AS 'ALIAS2' FROM TABLE1 WHERE CONDITION1 = CONDITION";
or
String sql = "SELECT COLUMN1 AS " + "ALIAS1" + ", COLUMN2 AS " + "ALIAS2" + " FROM TABLE1 WHERE CONDITION1 = CONDITION";
有人可以帮助我.. 我用过＆＃34;＆＃39; ＆＃39;＆＃34;它显示了JAVA编制时间的错误..
我使用的是Eclipse IDE ..我的数据库是Oracle ..
答案 0 :(得分：2)
在没有单引号的情况下运行它：
String sql = "SELECT COLUMN1 AS ALIAS1, COLUMN2 AS ALIAS2 FROM TABLE1 WHERE CONDITION1 = CONDITION";
答案 1 :(得分：1)
尝试转义"：
String sql = "SELECT COLUMN1 as \"ALIAS1\", COLUMN2 as \"ALIAS2\" FROM TABLE1 WHERE CONDITION1 = CONDITION";
