SQL Server System stored procedures
1. Add descriptive information to the fields in the table
Copy Code code as follows:

Create table T2 (id int, name char (20))
Go
EXEC sp_addextendedproperty ' ms_description ', ' Employee id ', ' user ', dbo, ' table ', T2, ' column ', ID
EXEC sp_updateextendedproperty ' ms_description ', ' This is a test ', ' user ', dbo, ' table ', T2, ' column ', ID

2. Modify Database name
Copy Code code as follows:

EXEC sp_renamedb ' old_db_name ', ' new_db_name '

3. Modify the data table name and field name
Copy Code code as follows:

EXEC sp_rename ' old_table_name ', ' new_table_name '-modifying datasheet name
EXEC sp_rename ' table_name. [Old_column_name] ', ' new_column_name ', ' column '-Modify field name

4. Get stored procedure contents given the stored procedure name
Copy Code code as follows:

EXEC sp_helptext Sp_name

The following is about database control
* The following is a system stored procedure or SQL statement about security control, detailed syntax to refer to "Books Online" Related content * *
– Create a new SQL Server login that enables users to connect to SQL Server that uses SQL Server authentication.
EXEC sp_addlogin @loginame = ', @passwd = ', @defdb = ', @deflanguage = null, @sid = NULL, @encryptopt = NULL
– Enable Windows NT User or group accounts to connect to SQL Server using Windows authentication.
EXEC sp_grantlogin @loginame = '
– Remove the SQL Server login to prevent access to SQL Server using the login name.
EXEC sp_droplogin @loginame = '

Stored Procedures for database restore

Copy Code code as follows:

SQL Code
Create proc killspid (@dbname varchar (20))
As
Begin
declare @sql nvarchar (500)
DECLARE @spid int
Set @sql = ' Declare getspid cursor for
Select spid
From sysprocesses
where dbid=db_id (' + @dbname + ') '
EXEC (@sql)
Open Getspid
FETCH NEXT from Getspid
Into @spid
While @ @fetch_status <>-1
Begin
EXEC (' kill ' + @spid)
FETCH NEXT from Getspid
Into @spid
End
Close Getspid
Deallocate getspid
End
Go

Role: Kill the activities in the incoming database for exclusive operations such as backup restores

=================== Arabic numeral to Capital Chinese =============
Example: Input 12345, the program gives: one million thousand thousands of restaurants to collect Wu
Example: Enter 10023040, the program gives: one thousand Wan another to pick up
One of the solutions (tested in SqlServer2000):

Copy Code code as follows:

SQL Code
CREATE FUNCTION Fun_cgnum
(@num INT)
RETURNS VARCHAR (100)
As
BEGIN
DECLARE @temp INT, @res int,@i TINYINT
DECLARE @str VARCHAR (m), @no VARCHAR (a), @unit VARCHAR (16)
SELECT @str = ', @no = ' Another three Woolu qi Ba nine ', @unit = ' Collect bai thousand million '
SET @temp = @num
SELECT @i=0, @res = @temp%10, @temp = @temp/10
While @temp >0
BEGIN
IF @i=0
SET @str =substring (@no, @res +1,1)
ELSE
SET @str =substring (@no, @res +1,1) +substring (@unit, @i,1) + @str
SELECT @res = @temp%10, @temp = @temp/10
SET @i=@i+1
End
SET @str =substring (@no, @res +1,1) +substring (@unit, @i,1) + @str
SET @str =replace (@str, ' pick up ', ' another ')
SET @str =replace (@str, ' Bai ', ' another ')
SET @str =replace (@str, ' another ', ' another ')
SET @str =replace (@str, ' pick up ', ' another ')
SET @str =replace (@str, ' Another million ', ' million ')
While @i>0
BEGIN
SET @str =replace (@str, ' another ', ' another ')
SET @i=charindex (' other ', @str)
End
SET @str =replace (@str, ' Another million ', ' million ')
SET @str =replace (@str, ' billions ', ' billion ')
IF Right (@str, 1) = ' another '
SET @str =left (@str, LEN (@str)-1)
Return @str
End
Go

--Test: There are 0 and no 0 cases
SELECT Dbo.fun_cgnum (900000000), Dbo.fun_cgnum (903002051), Dbo.fun_cgnum (903002050)
PS: Interested friends can continue to consider the decimal point and add units (Yuan/PT/min) Situation
