Dear All,

I have a Table named as T1 which has 50 columns.

I need to write a query to change the datas in the 50 columns to uppercase by using a single query.

with expectation,

推荐答案

类似的东西:

Something like:

UPDATE MyTable
   SET Col1 = UPPER(Col1),
       Col2 = UPPER(Col2), ....

SELECT 'UPDATE YOURTABLENAME SET ' + name + '=' + 'UPPER(' + name + ')'
FROM syscolumns
WHERE id = object_id('YOURTABLENAME')

这将创建一个查询，只需将其复制粘贴并运行即可.

注意:删除标识列(如果有).否则会引发错误.

希望对您有所帮助.

This will create a query just copy-paste it and run it.

NOTE : Remove identity column if any. Otherwise it will raise an error.

Hope it helps.

此查询可以做到.

This query will do it.

declare @sql        VARCHAR(8000)
declare @tableName  SYSNAME
set     @tableName  = ''yourTableNameGoesHere''

set     @sql = ''UPDATE '' + @tableName + '' SET '' + 
        (
        select  QUOTENAME(COLUMN_NAME) + '' = UPPER('' + QUOTENAME(COLUMN_NAME) + ''), ''
        from    INFORMATION_SCHEMA.COLUMNS
        where   TABLE_NAME = @tableName
                AND
                DATA_TYPE IN(''char'',''varchar'',''nchar'',''nvarchar'')
        order
        by      ORDINAL_POSITION
        for xml path('''')
        )
---- remove last ", "
set     @sql = LEFT( @sql, LEN(@SQL)-1)
print @sql
---- uncomment next line to execute the query
--exec (@sql)
