Below is my summary of some of the content, which biased the implementation of T-SQL statements, the SQL Server Management Studio in the object manager's operation does not have much to summarize, because these are some wizards, and most of them are in the corresponding node, right click to find the appropriate action , the corresponding object, and then the Basic Wizard to operate! The first is the summary of the approximate knowledge points: Below is a summary of some T-SQL statements, 1,

backing up these VMDK files (and, of course, related configuration files). But in most cases, that is not the case. Unless the virtual machine (VM) is turned off, the backup VM cannot overwrite all files in the running state. In other words, this type of backup does not guarantee data consistency, and therefore does not guarantee that the restored VM contains enough precise information to indicate that the server has recovered successfully. As for the problem of excessive resource consumption

SQL Server supports many different types of backups, but the most common are full, differential, and transaction log backups. In the final analysis of which backup to use also refer to the recovery model of the database, such as the simple recovery model does not support transaction log backups.Full backupBack up all the data in the specified database, the cost of backup and recovery is higher when the data

in SQL Server. As you can see, there is no active SQL Server connection, which does not necessarily mean that the process is in a static state. It may be busy executing one or more background tasks. If I/O activities are still in progress after all database activities are completed for a long time, you may also need to check whether the scheduled job is running. Q: I am a non-voluntary DBA and are trying different tasks to get familiar with my work as soon as possible. The former DBA sets up a

example, first let a machine execute choose, select a modification time, and put it into the buffer. The choose function returns the buffer, and then execute, its second parameter extra is the content in the buffer (that is, the modification time ). That is to say, for a request, first call choose to select the values that will cause divergence on a machine as the result to be returned, then the result is broadcast to other machines for execution as the execute parameter, so that consistency is

power outages, and the problem may be a server operating system crash. If an instance failure is found, Oracle automatically completes the instance fix. Instance repair restores the database to a transactionally consistent state before the failure, and Oracle automatically rolls back uncommitted data. 　　4. Media failure A media failure is a failure that occurs when a database file or disk is unreadable or cannot be written. Second, backup The backup is to create a copy of the database to disk

1, Xtrabackup principle 1 Xtrabackup can only back up the tables of InnoDB and xtradb two engines, but not the MyISAM engine's tables; The 2 Innobackupex is a xtrabackup perl script that supports simultaneous backup of both InnoDB and MyISAM, but requires a global read lock for MyISAM backups. And there's the MyISAM. Incremental backups are not supported. (1) Total preparation principle 1 will start a xt

is consistent with the transaction before the failure, and Oracle automatically rolls back uncommitted data.4. Media failureA media failure is a failure that occurs when a database file, a portion of a file, or a disk is unreadable or cannot be written. For example, damage to the hard disk head can result in a complete corruption of the database file. To fix database file corruption due to media failure, you need to use media recovery.Second, the classification of backup1, from the physical and

copying a database to a dump device. Where the dump device refers to a tape or disk that is used to place a copy of the database. The following are categorized from different angles: 1) Classification from physical and logical anglesFrom a physical and logical point of view, backups can be divided into physical and logical backups.① Physical Backup:A backup of physical files (such as data files, c

model, after the completion of data processing, the recovery mode is immediately changed back to the full database schema.Simple Recovery ModelIn the simple recovery model, the database automatically deletes inactive logs, thus simplifying the restore of the backup, but because there is no log backup, it cannot be recovered to a point in time of failure. Typically, this pattern is only used for databases that do not require a high level of database security. And the database can only make full
