二>。常用的四种SQL命令:
1.查询数据记录(Select) 语法:Select 字段串行 From table Where 字段=内容 例子:想从book表中找出作者为"cancer"的所有记录,SQL语句便如下: select * from book where author='cancer' "*"是取出book表所有的字段,如查询的字段值为数字,则其后的"内容"便无须加上单引号,
如是日期,则在Access中用(#)包括,而在SQL server中则用(')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)
