Microsoft SQL Server Express是微软公司的关系数据库產品SQL Server的免費下載版本，可自由下載、分發及使用。這個版本的設計是專門為嵌入式系统或較小型的程式而設計。本產品可遡源至過往隨同SQL Server 2000軟件分發的Microsoft Database Engine (MSDE)，用以讓程式開發者在其測試其程式時建立一個系統需求較低的測試環境。自SQL Server 2005開始，本產品改用現時的名稱。

Capabilities

SQL Server Express provides many of the features of the paid, full versions of Microsoft SQL Server database management system.[3] However it has technical restrictions that make it unsuitable for some large-scale deployments. Differences in the Express product include:

  • Maximum database size of 10 GB per database in SQL Server 2016, SQL Server 2014, SQL Server 2012, and 2008 R2 Express[4] (4 GB for SQL Server 2008 Express and earlier; compared to 2 GB in the former MSDE). The limit applies per database (log files excluded); but in some scenarios users can access more data through the use of multiple interconnected databases.
  • No SQL Server Agent service[5][6]
  • Artificial hardware usage limits:
    • Single physical CPU, but multiple cores allowable[7]
    • 1 GB of RAM (runs on a system with higher RAM amount, but uses only at most 1 GB per instance of SQL Server Database Engine. "Recommended: Express Editions: 1 GB All other editions: At least 4 GB and should be increased as database size increases to ensure optimal performance."[8]).[9] Express with Advanced Services has a limit of 4 GB per instance of Reporting Services (not available on other Express variants). Analysis Services is not available for any Express variant.

Unlike the predecessor product, MSDE, the Express product does not include a concurrent workload-governor to "limit performance if the database engine receives more work than is typical of a small number of users."[10]

SQL Server Express includes several GUI tools for database management. These include:

The predecessor product MSDE generally lacked basic GUI management tools,[12]

Features available in SQL Server "Standard" and better editions but absent from SQL Server Express include:

Variants

Microsoft makes SQL Server Express available as:

  • An integrated edition with management tools
  • Core database-engine only
  • A SQL Server Express with Advanced Services edition (first introduced relatively late in Q2 2006 compared to the original release) with a reduced-functionality version of SQL Server Reporting Services and with full-text search capabilities

In the Free 2005 Express version, for example, a standard approach to installation options was provided, as follows. Generally, the SQL 2005 Express installers are packaged with the following consistent naming convention:

SQLEXPR.EXE
Has installers for BOTH 32-bit and 64-bit processors, but is a basic install
SQLEXPR32.EXE
Has ONLY the installer for 32-bit processors (still the basic install)
SQLEXPRWT.EXE
Has installers for BOTH 32-bit and 64-bit processors and SQL Server Management Studio Express (SSMSE) (2008 R2)
SQLEXPR_ADV.EXE
Has the basics and SQL Server Management Studio Express (SSMSE) + Reporting and Full Text Queries
SQLEXPR_TOOLKIT.EXE
Has the basics and SSMSE and Business Intelligence Development Studio (BIDS)

These optional variants have gone through several service packs (SP), and each SP installer can be used without using the older ones first:

  • Originals of the above files all carry the version number 9.0.1399.6
  • Service Pack 2 (SP2) versions all carry the version number 9.0.3042
  • Service Pack 3 (SP3) versions all carry the version number 9.00.4035
  • Service Pack 4 (SP4) versions all carry the version number 9.00.5000
