用PHP语句实现查询多张表 表的字段是相同的、表名不同。例如：
abc201202,abc201203,abc201204...表名按月建的表
我新手不知道怎么一次遍历多张表，提取MYSQL中的数据。
------解决方案--------------------
- PHP code
$table = array("abc201202","abc201203","abc201204");$result =array();foreach($table as $table_name) { $sql = "select * from ".$table_name; $rec =mysql_query($sql); while($row=mysql_fetch_row($rec)) { $result[] = $row; }}
------解决方案--------------------
- PHP code
$select = array();$table = array("abc201202","abc201203","abc201204");foreach($table as $v) { $select[] = "(select * from $v)";}$sql = join(' UNION ', $select);$res = mysql_query($sql);
------解决方案--------------------
- PHP code
$table = array("abc201202","abc201203","abc201204");$result=array();$count = count($table)-1;//减去一个数组下标for ($i=0;$i<$count;$i++){ $sql = $sql." select * from '".$table[$i]."' union all";}$sql=$sql." select * from '".$table[$count]."'";$rec =mysql_query($sql); while($row=mysql_fetch_row($rec)) { $result[] = $row; }
