[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。

Explain the InnoDB Buffer Pool and its importance for performance.Explain the InnoDB Buffer Pool and its importance for performance.Apr 19, 2025 am 12:24 AM

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.
