AlwaysOn versus Active Data Guard—A Value Proposition
TRANSFER SQL SERVER LOGINS BETWEEN 2 DIFFERENT SERVERS
1. RUN BELOW SCRIPT ON SOURCE SERVER 2. RUN BELOW COMMAN ON SOURCE SERVER TO CREATE LOGIN SCRIPTS 3. APPLY THE LOGIN SCRIPTS ON DESTINATION DATABASE FOR EG:
Execute Job from Stored Procedure
To Execute a job from inside a stored procedure. Normally if the above statement is not used you will get an error like "The module depends on the missing object 'sp_start_job'."
Delete Large Number of Rows SQL Server
To delete rows without locking a table which has say more than 100 million rows to be deleted. Or a large table with archived data has to be deleted. You can use the below function to do this deletion.
Select Random Rows from Table in SQL Server
To Select 1 Random Records from a table in SQL Server SELECT TOP 1 * FROM Table_Name ORDER BY NEWID() ; To Select 10 Random Records from a table in SQL Server SELECT TOP 10 * FROM tAudit ORDER BY NEWID()
Remove Null Rows SQL Server
DELETE FROM TABLENAME WHERE (COLUMN_NAME IS NULL OR COLUMN_NAME = 0); If you have additional columns containing NULL values and you want to refine your delete criteria DELETE FROM TABLENAME WHERE (COLUMN_NAME IS NULL OR COLUMN_NAME = 0) AND (COLUMN_NAME_1 IS NULL OR COLUMN_NAME_1 = 0) AND (COLUMN_NAME_2 IS NULL OR COLUMN_NAME_2 = 0) ;
Check for Listening Port SQL Server
DECLARE @tcp_port nvarchar(5) EXEC xp_regread @rootkey = 'HKEY_LOCAL_MACHINE', @key = 'SOFTWARE\MICROSOFT\MSSQLSERVER\MSSQLSERVER\SUPERSOCKETNETLIB\TCP', @value_name = 'TcpPort', @value = @tcp_port OUTPUT select @tcp_port
Create login SQL Server 2008
1. Go to Login > Properties > Create New Login
Attach Deattach Database T-SQL SQL Server 2005 2008
-- Attach a database USE master; GO CREATE DATABASE ON (FILENAME = 'd:\sql data\dbname.mdf'), (FILENAME = 'd:\sql data\dbname_Log.ldf') FOR ATTACH; GO -- Dettach database and take offline -- USE master; GO ALTER DATABASE SET OFFLINE WITH ROLLBACK IMMEDIATE go EXEC sp_detach_db @dbname = N'dbname'; GO
