如何更改T-SQL中的SQL Server列名？

我有一个从CSV文件导入的600多个列的表，列名称中有特殊的字符%\。 有没有办法更改列名以删除这些特殊字符

代码可以是T-SQL。

您可以使用这个吗

sp_RENAME 'Table.ColumnName%', 'NewColumnName' , 'COLUMN'

?

工作示例不确定sp_重命名中的[]

CREATE TABLE foo ([Oh%Dear] int)

EXEC sp_rename 'foo.[Oh%Dear]', 'OhDear', 'COLUMN'

EXEC sys.sp_help 'foo'

---

您可以查询信息\u SCHEMA.COLUMNS并生成sp\u重命名脚本来重命名这些列

SELECT 'EXEC sp_rename ''' + TABLE_NAME + '.' + QUOTENAME(COLUMN_NAME) + ''', ''' + REPLACE(COLUMN_NAME, '%', '') + ''', ''COLUMN''; '
FROM INFORMATION_SCHEMA.COLUMNS
WHERE COLUMN_NAME LIKE '%[%]%'

---

这里有一个例子，它将在一个表上循环并更改下划线和百分号

create table Test ([col%1] varchar(50),[col_2] varchar(40))
go

select identity(int,1,1) as id ,column_name,table_name into #loop
 from information_schema.columns
where table_name = 'Test'
and column_name like '%[%]%'
or column_name like '%[_]%'


declare @maxID int, @loopid int
select @loopid =1
select @maxID = max(id) from #loop

declare  @columnName varchar(100), @tableName varchar(100)
declare  @TableColumnNAme varchar(100)
while @loopid <= @maxID
begin


select @tableName = table_name , @columnName = column_name
from #loop where id = @loopid

select @TableColumnNAme = @tableName + '.' + @columnName
select @columnName = replace(replace(@columnName,'%',''),'_','')
EXEC sp_rename @TableColumnNAme, @columnName, 'COLUMN';

set @loopid = @loopid + 1
end

drop table #loop

select * from Test

我不知道tsql，但我想我知道tsql的答案。

create table Test ([col%1] varchar(50),[col_2] varchar(40))
go

select identity(int,1,1) as id ,column_name,table_name into #loop
 from information_schema.columns
where table_name = 'Test'
and column_name like '%[%]%'
or column_name like '%[_]%'


declare @maxID int, @loopid int
select @loopid =1
select @maxID = max(id) from #loop

declare  @columnName varchar(100), @tableName varchar(100)
declare  @TableColumnNAme varchar(100)
while @loopid <= @maxID
begin


select @tableName = table_name , @columnName = column_name
from #loop where id = @loopid

select @TableColumnNAme = @tableName + '.' + @columnName
select @columnName = replace(replace(@columnName,'%',''),'_','')
EXEC sp_rename @TableColumnNAme, @columnName, 'COLUMN';

set @loopid = @loopid + 1
end

drop table #loop

select * from Test
