found_rows():select row_count(): update delete insert
注:需要配合相应的操作一起使用,否则返回的值只是1和-1(都是不正确的值)
php示例代码如下:
drop database if exists `mytest`; create database `mytest`; use `mytest`; drop table if exists `MyTestTable`; create table `MyTestTable`(`ID` int ,`Name` varchar(10)); insert into `MyTestTable`(`ID`,`Name`) select '1','role1' union all select '2','role2' union all select '3','role3'; select row_count(); -- 输出3(返回新添加的记录数),[注:如果使用insert into...values只返回1] select * from `MyTestTable`;select found_rows(); -- 输出3(返回选择的行数) update `MyTestTable` set `Name`='people';select row_count(); -- 输出3(返回修改的行数) delete from `MyTestTable`;select row_count(); -- 输出3(返回删除的行数)
function mysql_modified_rows () { $info_str = mysql_info(); $a_rows = mysql_affected_rows(); ereg("Rows matched: ([0-9]*)", $info_str, $r_matched); return ($a_rows < 1)?($r_matched[1]?$r_matched[1]:0):$a_rows; }
希望本文所述对大家的php程序设计有所帮助。
