好在係網上搵到以下呢個 procedure:
  1. Click “All Programs”, select “Accessories”, right click the Command Prompt shortcut and select “Run as Administrator”.
  2. Click “Yes” to accept the warning
  3. Use command “cd” to navigate to the installation directory.
  4. Type the installation file to execute file. (e.g. SQLServer2005_SSMSEE_x64.msi) and complete the installation.

經過我 rebuild 過接近 10 個已有既 index 之後 (等了好幾分鐘), 搜尋時間減少至只需 5 秒…

以下係 mssql 2005 下 rebuild index 既一個 statement 既例子

ALTER INDEX IX_tblMaster ON tblMaster REBUILD;

IX_tblMaster 係 index 名
tblMaster 係 table 名
