The syntax is “descr ‘tablename’”

Have fun,

If you simply type SP_HELP in a query window you will get a list of all db objects including views, table, stored procedures, etc.

If you type sp_help SomeTableName it will provide a lot of information regarding that table. Table columns, datatype, nullability, etc. It also shows constraints on your table, etc. It tells you if you have an Identity column defined and the parameters for the Identity column. There are number of other things it provides…great tool.

sp_index SomeTableName will provide detail index list and the index properties.

If you are doing database work much in SQL server it will save you a lot of time to read through Books Online or TSQL Help on the stored procedures starting with SP_ and XP_. There are lot that you can skip for scheduling and replication if you are not using those featuers. But, the others will provide a lot of information.

Cheers
