⑷ SQL计算行内有多少个相同的关键字
select TD,len(AAA)-len(replace(AAA,'0','')) from 表
⑸ SQL语法关键字有多少
统计这东西基本没什么意义，这么多，基本上也记不住，经验丰富的人，在用到基穗疑似关键字的词语时，查一下帮助就知道了，或者有些工具像你说的，用颜搏搜卜色标识出来，一眼就看到了
数据库漏滑版本不断升级，关键字也在不断扩充。
⑹ sql如何查询整个数据库包含abc关键字的数据
先把数据库中所扰尺有表名称找知察到 ,然后缓猛高逐个表查询
declare @name varchar（50）,@tt varchar(10)
set @tt = '%abc%'
declare cc cursor for
select name from sysobjects where xtype='U'
open cc
fetch cc into @name

比如我有一个aaa 表，字段为哗带payed ，其中有两个关键字 ‘1’ 和 ‘2’
查出数据为2列没芦喊的话：
select (select COUNT(payed) from aaa where payed like '%1%') as a,(select COUNT(payed) from aaa where payed like '枯野%0%') as b
查出数据为1列的话：
select COUNT(*) from aaa group by payed having payed like '%1%' or payed like '%0%' order by payed desc
⑼ sql如何查询整个数据库包含abc关键字的数据
select count(*) from (select * from mysql where mysql.sqlbt like '%a05783%')
再试试update tab set 字段名 = replace(字段名,'a','b');
declare @name varchar（50）,@tt varchar(10)
set @tt = '%abc%'
