Add a stored procedure for SQL to view the table structure

There are too many tables in the database. It is difficult to view the structure of a table, so it is easier to use this stored procedure;

CRM
/* **************************************** ***
* Obtain table information based on the table name, including field descriptions.
**************************************** *** */
Create Proc [ DBO ] . [ Sp_help_table ]
( @ Tablename Varchar ( 200 ), @ Columnlike Varchar ( 200 ) = Null )
As
-- If the table name does not exist, select a similar table.
If Not Exists (
Select 1
From Sysobjects
Where ID = Object_id (@ Tablename )
And Type = ' U '
)
Begin
Select Name From Sysobjects
Where Name Like ' % ' + @ Tablename + ' % ' And Type = ' U '
Return
End


-- Filter similar column names
If ( @ Columnlike Is Null )
Set @ Columnlike = ''

Declare @ Columntable Table (Cname Varchar ( 200 ))
Insert @ Columntable
(
Cname
)
Select A. Name
From Syscolumns A, sysobjects d
Where A. ID = D. id
And D. Name = @ Tablename
And A. Name Like ' % ' + @ Columnlike + ' % '

When Columnproperty (A. ID, A. Name, ' Isidentity ' ) = 1 Then ' √ '
