I needed to find out types of columns in one sybase database. Usual SQL standard „describe table“ didn’t work. I google a bit and found this solution.
Single command list all db objects:
kfsql-1) sp_help;
Name Owner Object_type
------------------------------ ------------------------------ ----------------------
INSTANCES dbo view
myapp_Audit dbo user table
myapp_Bindings dbo user table
myapp_CPSInstances dbo user table
...
(48 rows affected)
User_type Storage_type Length Nulls Default_name Rule_name Access_Rule_name
--------------- --------------- ----------- ----- --------------- --------------- ----------------
Class_name Jar_name
------------------------------ ------------------------------
Jar_name
------------------------------
(return status = 0)
When you add table name, it gives you lot of details for that table, including types of columns:
kfsql-1) sp_help myapp_Instances;
Name Owner Object_type
------------------------------ ------------------------------ --------------------------------
myapp_Instances dbo user table
(1 row affected)
Data_located_on_segment When_created
------------------------------ ------------------------
