I have a table called table1
with two coloumns "id" and "name". The values are :
我有一个名为table1的表,有两个coloumns“id”和“name”。价值观是:
id name
----------------
(A1001 abc)
(A1002 bcd)
(A1003 cde)
(A1004 def)
I'm trying this query:
我正在尝试这个查询:
select distinct id,name
from table1
where id like '%1%' or name like '%c%' and id <> 'A1002'
It is not working. I want to get all the id and names that are like '1' or 'c' but want to exclude the row whose id is 'A1002'.
它不起作用。我想得到所有的id和名称,如'1'或'c',但想要排除id为'A1002'的行。
