Php Mssql操作简单封装支持存储过程

核心代码：

host = $host;
    $this->user = $user;
    $this->keys = $keys;
    $this->base = $base;
  }
  
  function connect() {
    $this->link = mssql_connect($this->host, $this->user, $this->keys);
    if (!$this->link) {
      die('connecting failed...check the module and setting...');
    }
    $select = mssql_select_db($this->base, $this->link);
    if (!$select) {
      die('data base is not exist...,please checke it ...');
    }
  }
  
  function executeProcedur($pName, $parName, $sqlTyle) {
    $this->connect();
    $stmt = mssql_init($pName, $this->link);
    if (isset($parName)) {
      $i = 0;
      foreach ($parName as $par => $value) {
 mssql_bind($stmt, $par, $value, $sqlTyle[$i]);
 ++$i;
      }
      $res = mssql_execute($stmt);
      $this->close();
      while ($row = mssql_fetch_assoc($res)) {
 $r[] = $row;
      }
      unset($i);
      mssql_free_result($res);
      mssql_free_statement($stmt);
      return $r;
    }
  }
  
  function executeProcedurNoPar($pName) {
    $this->connect();
    $stmt = mssql_init($pName, $this->link);
    $res = mssql_execute($stmt);
    $this->close();
    while ($row = mssql_fetch_assoc($res)) {
      $r[] = $row;
    }
    mssql_free_result($res);
    mssql_free_statement($stmt);
    return $r;
  }
  
  function getRowArray($sql) {
    $res = $this->query($sql);
    $r = mssql_fetch_row($res);
    mssql_free_result($res);
    return $r;
  }
  
  function getRowObject($sql) {
    $res = $this->query($sql);
    $r = mssql_fetch_assoc($res);
    return $r;
  }
  
  function query($sql) {
    $this->connect();
    $res = mssql_query($sql, $this->link);
    $this->close();
    return $res;
  }
  
  function getResult($sql) {
    $res = $this->query($sql);
    while ($row = mssql_fetch_assoc($res)) {
      $r[] = $row;
    }
    unset($row);
    mssql_free_result($res);
    return $r;
  }
  
  function executeSql($sql) {
    return $this->query($sql);
  }
  
  function querySql($sql) {
    $this->connect();
    mssql_query($sql, $this->link);
    $affected = mssql_rows_affected($this->link);
    $this->close();
    return $affected;
  }
  
  function close() {
    mssql_close();
  }
}
?> 

下面说下调用

function __autoload($MssqlUtil) { 
require $MssqlUtil.'.php'; 
} 
$db = new MssqlUtil($config['host'],$config['user'],$config['keys'],$config['base']); 

主要说下带参数的存储过程调用

$pName 存储过程名字 
$parName 参数，参数形式很重要，是数组类型，对应关系为 
array('@a'=>'a') @a 为存储过程里面的参数，a为要传递的值 
$sqlTyle 是存储过程参数的数据类型，是数组形式，也很重要 
array(SQLCHAR,SQLVARCHAR),注意不要加单引号等，因为SQLVARCHAR是SQL的一些常量 

带参数存储过程 
$db->executeProcedur($pName,$parName,$sqlTyle); 
无参数存储过程 
$db->executeProcedurNoPar($pName); 

select * from t2 where t2.id in(select max(t2.id) from t1 join t2 on t1.id = t2.pid group by t1.id);
取每个分类的最新一条数据。此处做个记录。
t1为类别表，t2为主表
