Microsoft SQL Serverでは、これを使用できます。
declare @sql2 nvarchar(2000)
set @sql2 ='
use ?
if ( db_name(db_id()) not in (''master'',''tempdb'',''model'',''msdb'',''SSISDB'') )
begin

SO.name tablename,
SC.name columnname,
ST.name type,
case when ST.name in (''nvarchar'', ''nchar'')
then convert(varchar(10), ( SC.max_length / 2 ))
when ST.name in (''char'', ''varchar'')
then convert(varchar(10), SC.max_length)
else null
end as length,
case when SC.is_nullable = 0 then ''No'' when SC.is_nullable = 1 then ''Yes'' else null end as nullable,
isnull(SC.column_id,0) as col_number
