sql语句进行 like和in 参数化,按照正常的方式是无法实现的 我们一般的思维是: Like参数化查询:string sqlstmt = "select * from users where user_name like '%@word%' or mobile like '%@word%'";SqlParameter[] Parameters=new SqlParameter[1];Parameters[0] = new SqlParameter("@word"
本文只是写一些常用es命令,这里不用任何客户端,只用 9200/_plugin/head/ 那个端口网页就可以,然后是复合查询. 注意es其实一个idnex只能有一个type,如果一个index做了多个type,坑...太多了,首先 where不能用,然后 聚合也不能用.至少在es2.*是这样的,这个坑你可以搜索下"_type Field Not Available for Aggregation #5634" 1. 查询所有关键字:match_all等同SQL select * fr
一.SQL子查询语句 1.单行子查询 select ename,deptno,sal from emp where deptno=(select deptno from dept where loc='NEW YORK'): 2.多行子查询 SELECT ename,job,sal FROM EMP WHERE deptno in ( SELECT deptno FROM dept WHERE dnam
