<二>。常用的四種SQL命令：
1.查詢數據記錄(Select) 語法：Select 字段串行 From table Where 字段=內容 例子：想從book表中找出作者為"cancer"的所有記錄，SQL語句便如下： select * from book where author='cancer' "*"是取出book表所有的字段，如查詢的字段值為數字，則其后的"內容"便無須加上單引號，
如是日期，則在Access中用(#)包括，而在SQL server中則用(')包括， 如:
select * from book where id=1 select * from book where pub_date=#2002-1-7# (Access) select * from book where pub_date='2002-1-7' (SQL Server)
