SQL Server UPPERCASE for all data for all columns in the table

Question

I would like to know how to convert all data to UPPERCASE for all columns name and the values in them for a table. The data may contain int but it will ignore it. S

Answer 1

Unfortunately, you can't to that directly. You need to specify each column names that need to be updated. eg

UPDATE tablename
SET    col = UPPER(col)
       colN = UPPER(colN)

But, it's not the end of the world. You can still do that but with Dynamic SQL.

Answer 2

Dynamic SQL is probably your only option. Something like this should would using FOR XML querying INFORMATION_SCHEMA.COLUMNS:

declare @query varchar(max)
set @query = ''

select @query =
  STUFF((
    select ';UPDATE ' + table_name + ' SET ' + column_name + ' = UPPER(' + column_name + ')'
    from INFORMATION_SCHEMA.COLUMNS
    order by table_name, column_name
    for xml path('')
        ), 1, 1, '')

execute(@query);
