=Object_Id('表名') and colid=(select top 1 keyno from sysindexkeys where id=Object_Id('表名'))


[综合网络资料整理]

1.获取所有数据库名: 
   (1)
、Select Name FROM Master..SysDatabases order by Name 
2.
获取所有表名: 
   (1)、Select Name FROM SysObjects Where XType='U' orDER BY Name 
           XType='U':表示所有用户表; 
           XType='S':表示所有系统表;

   (2)、SELECT name FROM sysobjects WHERE type = 'U' AND sysstat = '83'

           注意:一般情况只需要type = 'U',但有时候会有系统表混在其中(不知道什么原因),加上后面一句后就能删除这些系统表了


3.
获取所有字段名: 
(1)
、Select Name FROM SysColumns Where id=Object_Id('TableName')

(2)、SELECT syscolumns.name,systypes.name,syscolumns.isnullable,syscolumns.length FROM syscolumns, systypes WHERE syscolumns.xusertype = systypes.xusertype AND "syscolumns.id = object_id('tableName')

       注意点:
     (a)这里为了重点突出某些重要内容,选取了其中几项信息输出。
     (b)syscolumns表中只含有数据类型编号,要获取完整的名字需要从systypes表中找,一般用户使用的数据类型用xusertype对应比较好,不会出现一对多的情况。
     (c)syscolumns.length得到的是物理内存的长度,所以nvarchar和varchar等类型在数据库中的显示是这个的一半。

4、得到表中主键所包含的列名:

    SELECT syscolumns.name FROM syscolumns,sysobjects,sysindexes,sysindexkeys WHERE syscolumns.id = object_id('tablename') AND sysobjects.xtype = 'PK' AND sysobjects.parent_obj = syscolumns.id AND sysindexes.id = syscolumns.id AND sysobjects.name = sysindexes.name AND sysindexkeys.id = syscolumns.id AND sysindexkeys.indid = sysindexes.indid AND syscolumns.colid = sysindexkeys.colid

注意:这是在4张系统表中寻找的,关系比较复杂,大致可以表示为:
syscolumns中存有表中的列信息和表id,sysobjects表中存有主键名字(即PK_Table类似)和表id,sysindexes中存 有主键名字和表id和index编号,sysindexkeys中存有表id和index编号和列编号,一项一项对应起来后就能找到列名了。

What is the difference between mysql and sqlserver syntax What is the difference between mysql and sqlserver syntax Apr 22, 2024 pm 06:33 PM

The syntax differences between MySQL and SQL Server are mainly reflected in database objects, data types, SQL statements and other aspects. Database object differences include the storage engine and how filegroups are specified, and the creation of indexes and constraints. Data type differences involve differences in numeric types, character types, and date and time types. SQL statement differences are reflected in result set limitations, data insertion, update and delete operations, etc. Other differences include how identity columns, views, and stored procedures are created. Understanding these differences is important to avoid errors when using different database systems.

iOS 18 adds a new 'Recovered' album function to retrieve lost or damaged photos iOS 18 adds a new 'Recovered' album function to retrieve lost or damaged photos Jul 18, 2024 am 05:48 AM

Apple's latest releases of iOS18, iPadOS18 and macOS Sequoia systems have added an important feature to the Photos application, designed to help users easily recover photos and videos lost or damaged due to various reasons.
