如何使用SQL获取Sybase ASE中的列类型

Question

我可以使用什么SQL来获取Sybase ASE中列的类型？

Answer 1

给出一个名为“ fruit”的表和一个名为“ color”的列：

select obj.name as "table", col.name as "column", type.name as "type"
  from sysobjects obj
  join syscolumns col on obj.id=col.id
  join systypes type on col.type=type.type and col.usertype = type.usertype
 where obj.type = "U"               -- means 'U'ser table
   and user_name(obj.uid) = 'dbo'   -- or whatever the user is who owns/created the table
   and obj.name = 'fruit' 
   and col.name = 'color'
