On-premise SQL Server provides a maintenance plan to maintain SQL Server on a regular, scheduled basis. As a general rule, define SQL Server Agent jobs, and the maintenance plan helps us Execute SQL Server Agent jobs on a regular, scheduled basis. Unfortunately, SQL database

. The difference between it and a normal full backup is that the differential backup benchmark does not change after it is done, so it does not affect the differential backup sequence.2. Copy-only log backupsA copy-only log backup backs up only the existing content in the current log file, but does not truncate the log, so the next time you do a normal log backup, the content restore is backed up again, without affecting the sequence of regular log backups. This backup is mainly used on the data

, database verification, object permission ). For example, if we look at the SQL Server as a building, we must first have the right to enter the building, that is, pass the building's door (login verification ), then you have to have access to a room (Database permission), and the right to open the safe after entering the room (Operation permission on the table ). That is, we must first create a login account, and the login account is divided into two

try it out before I dared to start with the actual database. The specific operation process should be as follows: 1. Back up the database before you start. In the dark of night, the system is usually relatively idle, and it may be easy to handle, there is a database backup, in case of a problem found the next morning, at least can be restored to yesterday's work point, the risk is relatively small. 2.

Label:The more written the SQL script, the more often it feels that writing is too inefficient, regardless of the speed of the typing.

feature of SQL Server cannot be used for the memory occupied by multi-page. That is to say, in a 32-bit SQL Server, even if AWE is enabled for the database, you can only use 2 GB of memory (user mode ). It can be seen that AWE improves the memory space of the data page buffer pool. Note: In 32-bit SQL Server, the default size of multi-page is 256 MB + the maximu

instance after the instance is created. For example: SQLLOCALDB create "Mylocaldb" 11.0-s You can view the status information for the MYLOCALDB instance using the following command: SQLLOCALDB Info "Mylocaldb" The command returns the following information:Figure two: Sqllocaldb info mylocaldbTo start and stop an LOCALDB instance: Sqllocaldb start "Mylocaldb" Sqllocaldb Stop "Mylocaldb" To delete a LocalDB instance: SQLLOCALDB Delete "Myloca

Only Remote Assistance in the way. I made a special script to use the phone to instruct the client to execute a script in SSMs. The difference between a 1.0 database and a 1.1 database is that one of the [Ct_outercard] tables in the 1.1 database has 6 more fields than 1.0, and all other tables are the same. There are a lot of stored procedures, and nothing else has changed. First of all, in the company's server database to generate a stored procedu
