MSSQL 經常使用操做

0.GUID去除橫線和變換爲小寫

SELECT  LOWER(REPLACE(LTRIM(NEWID()),'-',''))

1.IDENTITY 函數說明

IDENTITY ( data_type [ , seed , increment ] ) AS column_name
IDENTITY(numric,1,1)

2.將數據庫的日誌文件壓縮

ALTER DATABASE [DBName] SET RECOVERY SIMPLE  
ALTER DATABASE [DBName] SET RECOVERY FULL  
DBCC SHRINKDATABASE([DBName], 0)
