PHP MSSQL 存储过程的方法

function generatedoccode() {
$wf_id = self::workflow_id;
$doc_code = "";
$link = mssql_connect($this->cfg->db->params->host, $this->cfg->db->params->username, $this->cfg->db->params->password) or die("can't connect sql server");
mssql_select_db($this->cfg->db->params->dbname, $link) or die("select database failure");
$stmt = mssql_init("generatedoccode", $link) or die("initialize stored procedure failure");
mssql_bind($stmt, "@wf_id", $wf_id, sqlint4);
mssql_bind($stmt, "@doc_code", $doc_code, sqlvarchar, true);
mssql_execute($stmt, false);
//print "doc code is: ".$doc_code;
return $doc_code;
}

先调用mssql_init语句用于初始化存储过程，而后调用mssql_bind语句指定存储过程参数，最后调用mssql_execute执行存储过程。
