   最近在研究在数据库中存储大数据文件,看到了FileStream 这个功能,,记录下来以备后用

  FileStream 一般在安装的时候默认是不启用的,如果你留意的话,在选择数据库文件路径那个窗口,有一个标签是"FileStream".

  如果在安装的时候你没有启用,安装后可以通过以下设置来开启FileStream 功能。

  1. 打开 SQL Server 配置管理器, 在SQL server 服务下找到你要启用的SQL Server服务(默认实例一般是 MSSQLServer),右击该服务,选择属性,在属性窗口你可以看到FileStream 标签,选中" 针对 Transact-SQL 访问启用 FILESTREAM"

  2.执行以下命令在ssms

  EXEC sp_configure filestream_access_level, 2

  RECONFIGURE

  3.创建支持FileStream 的数据库,

  [sql]

  CREATE DATABASE test

  ON

  ( NAME = test_dat,

  FILENAME = 'C:Program FilesMicrosoft SQL ServerMSSQL11.MSSQLSERVERMSSQLDATAtestdat.mdf' ),

  FILEGROUP testGroup1 CONTAINS FILESTREAM

  ( NAME = testgroup_dat ,

  FILENAME = 'C:Program FilesMicrosoft SQL ServerMSSQL11.MSSQLSERVERMSSQLDATAtestGroup1.ndf')

  LOG ON

  ( NAME = Sales_log,

  FILENAME = 'C:Program FilesMicrosoft SQL ServerMSSQL11.MSSQLSERVERMSSQLDATAtestlog.ldf' ) ;

  当然你也可以用以下脚本,在已存在的数据库添加一个文件组用于支持FileStream.

  [sql]

  ALTER database test

  ADD FILEGROUP FileStreamRecord

  CONTAINS FILESTREAM

  GO

  --Add a file for storing database photos to FILEGROUP

  ALTER database test

  ADD FILE

  (

  NAME= 'FileStreamRecord',

  FILENAME = 'D:Program FilesMicrosoft SQL ServerMSSQL11.MSSQLSERVERMSSQLDATATestFileStreamRecord.ndf'

  )

  TO FILEGROUP FileStreamRecord

  GO

  4. 创建可以存储FileStream 的数据表

  CREATE TABLE FileStreamRecording

  [sql]

  (

  ID int,

  RowGuidColumn UNIQUEIDENTIFIER

  NOT NULL UNIQUE ROWGUIDCOL,

  FILESTREAMColumn varbinary(MAX) FILESTREAM

  );

  [sql]

  [sql]

  5.使用

  [sql]

  INSERT INTO FileStreamRecording VALUES(1, NEWID(), 0x00);

  INSERT INTO FileStreamRecording VALUES(2, NEWID(), 0x00);

  INSERT INTO FileStreamRecording VALUES(3, NEWID(), 0x00);

  GO

  SELECT FILESTREAMColumn.PathName() AS 'PathName' FROM FileStreamRecording;

What are stored procedures in MySQL?What are stored procedures in MySQL?May 01, 2025 am 12:27 AM

Stored procedures are precompiled SQL statements in MySQL for improving performance and simplifying complex operations. 1. Improve performance: After the first compilation, subsequent calls do not need to be recompiled. 2. Improve security: Restrict data table access through permission control. 3. Simplify complex operations: combine multiple SQL statements to simplify application layer logic.

How does query caching work in MySQL?How does query caching work in MySQL?May 01, 2025 am 12:26 AM

The working principle of MySQL query cache is to store the results of SELECT query, and when the same query is executed again, the cached results are directly returned. 1) Query cache improves database reading performance and finds cached results through hash values. 2) Simple configuration, set query_cache_type and query_cache_size in MySQL configuration file. 3) Use the SQL_NO_CACHE keyword to disable the cache of specific queries. 4) In high-frequency update environments, query cache may cause performance bottlenecks and needs to be optimized for use through monitoring and adjustment of parameters.

What are the advantages of using MySQL over other relational databases?What are the advantages of using MySQL over other relational databases?May 01, 2025 am 12:18 AM

The reasons why MySQL is widely used in various projects include: 1. High performance and scalability, supporting multiple storage engines; 2. Easy to use and maintain, simple configuration and rich tools; 3. Rich ecosystem, attracting a large number of community and third-party tool support; 4. Cross-platform support, suitable for multiple operating systems.

How do you handle database upgrades in MySQL?How do you handle database upgrades in MySQL?Apr 30, 2025 am 12:28 AM

The steps for upgrading MySQL database include: 1. Backup the database, 2. Stop the current MySQL service, 3. Install the new version of MySQL, 4. Start the new version of MySQL service, 5. Recover the database. Compatibility issues are required during the upgrade process, and advanced tools such as PerconaToolkit can be used for testing and optimization.

What are the different backup strategies you can use for MySQL?What are the different backup strategies you can use for MySQL?Apr 30, 2025 am 12:28 AM

MySQL backup policies include logical backup, physical backup, incremental backup, replication-based backup, and cloud backup. 1. Logical backup uses mysqldump to export database structure and data, which is suitable for small databases and version migrations. 2. Physical backups are fast and comprehensive by copying data files, but require database consistency. 3. Incremental backup uses binary logging to record changes, which is suitable for large databases. 4. Replication-based backup reduces the impact on the production system by backing up from the server. 5. Cloud backups such as AmazonRDS provide automation solutions, but costs and control need to be considered. When selecting a policy, database size, downtime tolerance, recovery time, and recovery point goals should be considered.

How do you optimize database schema design for performance in MySQL?How do you optimize database schema design for performance in MySQL?Apr 30, 2025 am 12:27 AM

Optimizing database schema design in MySQL can improve performance through the following steps: 1. Index optimization: Create indexes on common query columns, balancing the overhead of query and inserting updates. 2. Table structure optimization: Reduce data redundancy through normalization or anti-normalization and improve access efficiency. 3. Data type selection: Use appropriate data types, such as INT instead of VARCHAR, to reduce storage space. 4. Partitioning and sub-table: For large data volumes, use partitioning and sub-table to disperse data to improve query and maintenance efficiency.
