END
ELSE
  EXEC @err=sp_oamethod @srvid,'connect',NULL,@ServerName,@UserName,@pwd

IF @err0 GOTO lb_Err

--删除数据库
--这两个都可以删除
EXEC @err = sp_OAMethod @srvid,'KillDatabase',null,@Des_DB
IF @err0 GOTO lb_Err
/*
--
EXEC @err = sp_OAMethod @srvid,'Databases.Remove',null,@Des_DB

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.
