在mysql for php中执行多个sql删除查询

Question

出于某种原因,我想使用php mysql查询功能删除我表中的一些记录.这是我写的

$sql = "delete from progress where first_date='2010-01-01' and last_date='2010-01-31';
delete from progress where first_date='2010-02-01' and last_date='2010-02-28';
delete from progress where first_date='2010-03-01' and last_date='2010-02-31';
delete from progress where first_date='2010-04-01' and last_date='2010-02-30';
delete from progress where first_date='2010-05-01' and last_date='2010-02-31';";

if(!mysql_query($sql)) echo "Error deleting records";

这正是我得到的,"错误删除记录".但是当使用mysql_error()进行它时,它毕竟没用.任何人都知道如何处理这个？谢谢之前

出于安全原因,mysql_query()无法执行多个语句.

使用mysqli_multi_query()或多次调用mysql_query().
