今天删除数据,写了这么条sql语句, DELETE from sys_menus s WHERE s.MENU_ID in (86,87,88); 结果报错.. [Err] 1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 's WHERE s.MENU_ID

在用DELETE删除mysql数据库数据时采取一下两种方式: 方式一:DELETE FROM B_PROSON WHERE ID = 1; 不使用别名 方式二:DELETE BP FROM B_PROSON BP WHERE BP.ID = 1;使用别名 而其他的操作(SELECT,UPDATE)都和其他数据库一样(别名直接跟在表名后面就可以了) SELECT BP.* FROM B_PROSON BP WHERE BP.ID=1;
delete from exam_paper_question_opt a WHERE a.OPTION_ID = 65630 and a.QUESTION_ID = 28656 AND a.EXAM_PAPER_ID = 1533 [Err] 1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right synta
今天碰到一个sql问题,就是在delete中加了别名,导致报错了:"[Err] 1064 - You have an error in your SQL syntax; ..." 简单说下过程,本来是一个简单的delete语句: : 后需要增加关联条件,所以在后边追加了where条件,为了关联写着方便为表添加了别名,变为: 就是这样报错了,提示语法错误,觉得挺纳闷,将delete 换成 select * (通常为了省事,验证sql的时候换成select),没有问题,执行正确. 百度很多
FROM : http://blog.csdn.net/hi_box/article/details/40820341 首先用最普通的建表语句建一个表: hive>create table test(id int,name string)row format delimited fields terminated by ','; 测试insert: insert into table test values (1,'row1'),(2,'row2'); 结果报错: java.io.FileNot
如果入参是简单的数据类型,直接继承UDF,实现一个或者多个evaluate 方法. 具体流程如下: 1,实现大写字符转换成小写字符的UDF package com.example.hive.udf; import org.apache.hadoop.hive.ql.exec.UDF; import org.apache.hadoop.io.Text; public class Lower extends UDF { public Text evaluate(final Text s) { if
