為了能讓PHP連接MSSQL,系統(tǒng)需要安裝MSSQL,PHP,且在PHP.ini中的配置中,將 ;extension=php_mssql.dll前面的;去掉
1.連接MSSQL
$conn=mssql_connect("實(shí)例名或者服務(wù)器IP","用戶名","密碼"); //測試連接 if($conn) { echo "連接成功"; } 2.選擇要連接的數(shù)據(jù)庫
mssql_select_db("dbname"); 3.執(zhí)行查詢
$rs = mssql_query("select top 1 id,username from tbname",$conn);// 或者直接執(zhí)行update,insert等語句,可以不用為返回結(jié)果賦值mssql_query("update tbname set username='niunv' where id=1"); 4.獲取記錄集行數(shù)
echo mssql_num_rows($rs);
5.獲取記錄集
if($row=mssql_fetch_array($rs)) { $id = $row[0];//獲取ID字段值 $username = $row[1];//獲取username字段值 } 6.獲取新增記錄的ID
將id字段設(shè)置為IDENTITY字段,執(zhí)行insert語句以后,就會產(chǎn)生一個 @@IDENTITY 全局變量值,查詢出來就是最后一條新增記錄的ID了.
mssql_query("insert into tbname(username) values ('nv')",$conn); $rs = mssql_query("select @@IDENTITY as id",$conn); if($row=mssql_fetch_array($rs)) { echo $row[0]; } 7.釋放記錄集
mssql_free_result($rs);
8.關(guān)閉連接
mssql_close($conn);
注:用PHP操作MSSQL比在ASP連接MYSQL要簡單,所以,當(dāng)需要MSSQL與MYSQL并存時,用PHP連接MSSQL來操作MYSQL與MSSQL并存比較簡單好用.如果是ASP連接MYSQL,需要安裝一個MYSQL驅(qū)動,默認(rèn)windows的ODBC沒有安裝,很遺憾...
- 在web服務(wù)器上至少安裝了mssql的客戶端
- 打開php.ini把;extension=php_mssql.dll 前面的分號去掉
- 有必要話：需要制定extension_dir
- 推薦使用 php<=4.0.9 <=5.0.3目前 我還沒有連接成功過4.010和 5.0.3
- 數(shù)據(jù)庫的 連接分頁可以到phpe.net上獲取到相應(yīng)的class
下面是我修改的 一個class
<?php /** *mssql 數(shù)據(jù)庫連接類 **/ class SQL{ var $server; var $userName; var $passWord; var $dataBase; var $linkID = 0; var $queryResult; var $lastInsertID; var $pageNum = 0;//分頁用---共有幾條數(shù)據(jù) var $ER; /** *構(gòu)造函數(shù) **/ function SQL($Server='',$UserName='',$PassWord='',$DataBase=''){ $this->server = $Server; $this->userName = $UserName; $this->passWord = $PassWord; $this->dataBase = $DataBase; } /** *數(shù)據(jù)庫連接 **/ function db_connect(){ $this->linkID = mssql_pconnect($this->server,$this->userName,$this->passWord); if(!$this->linkID){ $this->ER = "db_connect($this->server,$this->userName,$this->passWord) error"; return 0; } if (!mssql_select_db($this->dataBase,$this->linkID)) { $this->ER = "mssql_select_db($this->dataBase,$this->lastInsertID) error"; return 0; } return $this->linkID; } /**public * function: Check the database, if exist then select * exist: return 1 * not exist: return 0 */ function selectDatabase(){ if(mssql_select_db($this->dataBase)) return 1; else return 0; } /** *數(shù)據(jù)操作 **/ function query($Str){ if ($this->linkID == 0) { $this->ER = "數(shù)據(jù)庫還沒有連接??！"; } $this->queryResult = mssql_query($Str); //$this->queryResult = mssql_query($Str,$this->linkID); if (!$this->queryResult) { $this->ER = "$Str.沒有操作成功,query error?。?quot;; return 0;//****************對于php 4.3.9以上版本的錯誤用1 } return $this->queryResult; } /** *數(shù)據(jù)獲取 **/ function fetch_array($result){ if($result != "") $this->queryResult = $result; $rec =mssql_fetch_array($this->queryResult); if(is_array($rec)){ return $rec; } //$this->ER = "沒有獲取數(shù)據(jù)！"; return 0; } /**public * function: Free the Query Result * success return 1 * failed: return 0 */ function freeResult($result=""){ if($result != "") $this->queryResult = $result; return mssql_free_result($this->queryResult); } /** *獲取影響的的行數(shù) *獲取操作過的行數(shù) **/ function num_rows($result=""){ if ($result != "") { $this->queryResult = $result; $row = mssql_num_rows($this->queryResult); return $row; } } /** *獲取查詢結(jié)果---多個 **/ function result_ar($str=''){ if (empty($str)) { return 0; } $back = array(); $this->queryResult = $this->query($str); while ($row = $this->fetch_array($this->queryResult)) { $back[] = $row; } return $back; } /** *數(shù)據(jù)庫信息分頁 *$Result 數(shù)據(jù)庫操作 *str ==sql語句 *page ==第幾頁 *showNum ==顯示幾頁 */ function page($Str,$Page=0,$ShowNum=5){ $back = array();//返回?cái)?shù)據(jù) $maxNum = 0; if ($Str == "") { $this->ER = "沒有數(shù)據(jù)"; return 0; } $this->queryResult = $this->query($Str); if($this->queryResult){ if($Page==""){ $nopa=0; }else{ $nopa = ($Page-1)*$ShowNum; if ($nopa<0) { $nopa = 0; } } $maxNum=$this->num_rows($this->queryResult); $k=0; $i=0; $dd=$this->fetch_array($this->queryResult); while($dd&&$nopa<=$maxNum&&$i<$ShowNum){ if($nopa >= $maxNum) $nopa = $maxNum; mssql_data_seek($this->queryResult,$nopa); $row=$this->fetch_array($this->queryResult); $nopa++; $i++; $back[] = $row; if ($nopa >=$maxNum) { break; } } } $this->pageNum = $maxNum; return $back; } /** *分頁的html頁碼 */ function page_html($DataNum=0,$Page=1,$ShowNum=3,$web,$Post=''){ if ($DataNum == 0) { $back = "沒有要查詢的數(shù)據(jù)"; }else { if ($ShowNum<=0) { $ShowNum = 3; } if ($Page<=0) { $Page = 1; } if (empty($web)) { $web = "#"; } $pageNum = ceil($DataNum/$ShowNum); if ($Page <= 1) { $top = "首頁<<"; }else { $top = "<a href='".$web."?page=0&".$Post."' target='_self'>首頁<< </a>"; } if ($Page !==1) { $upPage = "<a href='".$web."?page=".($Page-1)."&".$Post."' target='_self'>上一頁</a>"; }else { $upPage = "上一頁"; } if ($Page < $pageNum) { $downPage = "<a href='".$web."?page=".($Page+1)."&".$Post."' target='_self'>下一頁</a>"; }else { $downPage = "下一頁"; } if ($Page == $pageNum) { $foot = ">>尾頁"; }else { $foot = "<a href='".$web."?page=".$pageNum."&".$Post."' target='_self'> >>尾頁</a>"; } $back = <<<EOT 共 $pageNum 頁 第 $Page/$pageNum 頁 $top $upPage $downPage $foot EOT; } return $back; } }//end class ?> 以上就是PHP連接MSSQL方法的總結(jié)，希望對大家的學(xué)習(xí)有所幫助。
