LXXV. Microsoft SQL Server Functions

简介

These functions allow you to access MS SQL Server database.

需求

Requirements for Win32 platforms.

The extension requires the MS SQL Client Tools to be installed on the system where PHP is installed. The Client Tools can be installed from the MS SQL Server CD or by copying ntwdblib.dll from \winnt\system32 on the server to \winnt\system32 on the PHP box. Copying ntwdblib.dll will only provide access. Configuration of the client will require installation of all the tools.

Requirements for Unix/Linux platforms.

To use the MSSQL extension on Unix/Linux, you first need to build and install the FreeTDS library. Source code and installation instructions are available at the FreeTDS home page: http://www.freetds.org/

注: In Windows, the DBLIB from Microsoft is used. Functions that return a column name are based on the dbcolname() function in DBLIB. DBLIB was developed for SQL Server 6.x where the max identifier length is 30. For this reason, the maximum column length is 30 characters. On platforms where FreeTDS is used (Linux), this is not a problem.

安装

The MSSQL extension is enabled by adding extension=php_mssql.dll to php.ini.

To get these functions to work, you have to compile PHP with --with-mssql[=DIR], where DIR is the FreeTDS install prefix. And FreeTDS should be compiled using --enable-msdblib.

运行时配置

这些函数的行为受 php.ini 的影响。

The 3 major headaicks I had while setting up MS SQL 2005, php 5.1.6 (apache 2.2 server) on Vista RC1 and getting them to comunicate.



TCP/IP and "Named Pipes Protocol" had to be enabled in the MS SQL Server. You do this in the Surface Area Configuration tool.



MS SQL 2005 should be set to mix mode login. Unless you use NT authentication in php.ini.

You can do this in duing install if you select advanced options.

If it's already installed you will have to use the SQL management Studio (properties->securety).



At first the php_mssql.dll didn't load properly (wan't showing up under phpinfo()) and gave no error message at startup, the cause of this was the ntwdblib.dll that came with php (273KB) replacing it with the one that came with MS SQL 2005 (269KB) fixed the issuse, incase you haven't installed MS SQL on your machine you can also find it on the net.

With WinXP client, connecting to SQL Server 2005, via PHP on the command line (CLI).



If the serverr was installed with support for multiple instances, you can not connect to it, even when attempting to connect to the default instance.



Replace the ntwdblib.dll (7.00.839) provided by PHP with the one from SQL Server 2000 (8.00.194).



Otherwise you will see this message, which is not very helpful:

Warning: mssql_connect(): Unable to connect to server: ...

To connect to SQL Server 2005 you can download ntwdblib.dll from http://www.webzila.com/?wz=dll. Pick the smallest file there, the other one is French.

"if you are looking for the equivalent of  mysql_list_tables for mssql, try this..."



Please use the INFORMATION_SCHEMA views for this. Using the system tables for anything other than the occasional ad-hoc query is not recommended. See MSDN for more details.

Another helpful hint in regards to SQL Server 2005 Express:



Make sure your SQL Server is set to  "SQL Server and Windows Authentication mode". By default it is NOT.



1) Open "SQL Server Management Studio Express"

2) Right-click server ("machinename\sqlexpress") and select "Properties".

3) Select "Security"

4) Select "SQL Server and Windows Authentication mode"

5) Restart SQL Server.

mssql.datetimeconvert



using freebsd and freetds I ran into the dates month being rolled back

01 jan would be 00

12 dec would be 11 nov



removed

ini_set('mssql.datetimeconvert',false);

default setting is to 1 or true on the servers config

and the date issue I ran into was resolved



I don't know how the mssql.datetimeconvert setting works but if you're getting a roll back in dates might be worth making sure its on.



using ini_get when dealing with scripts that like to modify ini settings will save a headache if you use phpinfo() like me



*side note with the same settings in freetds php apache etc on a debian load I didn't have this issue even with mssql.datetimeconvert off

I had major latency problems with DB connections using php_mssql.dll without the client tools.  I found that by default it was using TCP/IP as the default connection method.   Installing the SQL Server client tools and using the Client Network Utility to change my settings to use named pipes resolved this issue.  You can use the Client Utility to set up a named pipes server alias and reference that in your connect string.

"Note: DBLib is obsolete and only supports SQL Server 4.x, 6.5, 7.0 and 8.x. "



Well, ntwdblib.dll is not distributed with SQL Native Client 2005 versions anymore, but it is what you need to use the mssql family functions with php. The distributed 7.x version with php does not work, but if you download the 8.x version distributed with SQL 2000 versions and replace it in your php directory, you can suddenly use mssql functions with no problems.

Actually, it's xtype, not type. So the the correct query would be something like:



SELECT name FROM sysobjects WHERE xtype = 'u' [ORDER BY whatever]

php5isapi / w2000 / ISS5



If you use the above configuration (isapi) and follow the suggestion to deselect 'cache isapi application' to avoid 100% processor usage, you might end up with an oocasional error:



The remote procedure call failed and did not execute. 



It happened to me every third visit to the same page.

RE-enabling caching resolved the issue.



M$ has an article about this in their knowledgebase, stating that this option should always be selected and is only there for developmentpurposes. (undocumented feature. :P)



Deselecting this option forces IIS to reload ALL relevant dll's every time a request is received in memory, also VB/ASP.

Some helpful functions.  Pretty simple, but very useful.



function mssql_begin_transaction() {

  mssql_query("BEGIN TRANSACTION");

}



function mssql_commit() {

  mssql_query("COMMIT");

}



function mssql_rollback() {

  mssql_query("ROLLBACK");

}



function mssql_insert_id() {

  $id = "";



  $rs = mssql_query("SELECT @@identity AS id");

  if ($row = mssql_fetch_row($rs)) {

  }

  mssql_free_result($rs);



  return $id;

I had problems related to VARCHAR limitation to 255 characters (INSERT/UPDATE works, SELECT was truncated) using freetds driver (Linux platform).



By upgrading the TDS protocol to 8.0 (see freetds config file), I fixed the problem.

I am trying to connect to SQL Server 2000 from PHP

I bumped to following warning:

Warning: mssql_connect(): Unable to connect to server: SERVER\Portal

....... on line 5



on line 5 there is:

$db_connect = mssql_connect('SERVER\Portal', 'sa', 'my_passwd');



I did the following

1.enabled php_mssql.dll extension in PHP.ini

2.every dll is in proper place(System32 or PHP folder),including ntwdblib.dll



I search lots of profile throught web ,but no one give me proper answer to resolve it.



after a few hour ,I found the problem was caused by

ntwdblib.dll ,which version is 7.00.839 ,when I replaced old ntwdblib.dll with the new ntwdblib.dll ,which version is 8.00.194 ,all problem are solved.

We had some, read A LOT, of problems with MSSQL under Windows 2003. 

We had 2 the same windows, php, php-ini, everything machines but only one could connect. Unable to connect was the error message.



Finnaly we checked the version of ntwdblib.dll and the one distributed with PHP was 7.00.... and the version of the one on the SQL Server install was 8.00.... so we copied this one in the php and apache dir and it worked.

With PHP 5 on a Windows 2000/IIS platform:



I have integrated authentication enabled in IIS.  I kept getting CGI timeouts on PHP pages for everyone but local administrators of the box.  The event log showed that PHP could not load php_mssql.dll, php_oci8.dll, and php_oracle.dll - 'Access Denied.'  



These extensions were executable by everyone, but the DLLs they depend on were not.  Had to add exec permissions for everyone to c:\winnt\system32\ntwdblib.dll as well as the oracle bin directory.

I've spent the last three days wild guessing why I could not connect to MS SQLServer 2000 and so I hope this might help someone else. Microsoft has purposefully closed the 1433 tcp port and others (maybe only to external ips) of the server. You can easily check if this is the case by looking at the Event Monitor. You should see an error produced by MSSQL SERVER/MSDE that basically says what I said. It suggests downloading and installing a security patch to open up the ports (but doesn't even say which update - remember this is Microsoft). 



Do download Service Pack 3a (SP3a). It does indeed fix the problem.

I was having problem in connecting Ms-SQL server with mssql_connect(srvr,uid,pwd). I simply created a DSN to my Database and replaced it with "server_name". i.e. 



mssql_connect(dsn,uid,pwd);



it worked well

Just a quick note pertaining marcos1979ar (10/06/04) definitive installation of FreeTDS above.



When you run the following to test the installation:

===============================================================

/usr/local/freetds/bin/tsql -S <ip of the server> -U <User SQL>

===============================================================



And it results in the following error:

=================================================================

locale is "C"

locale charset is "ANSI_X3.4-1968"

Password:

src/tds/login.c: tds_connect: xx.xx.x.xx:1443: Connection refused

Msg 20009, Level 9, State 0, Server OpenClient, Line 0

Server is unavailable or does not exist.

There was a problem connecting to the server

=================================================================



All I found that needed to be changed was for the configure --prefix from:



=======================================

./configure --prefix=/usr/local/freetds 

=======================================

         to

=======================================

./configure --prefix=/usr/local 

=======================================



Small but worth noting.

Buried away in the mssql_field_length documentation is an important limitation that it is certainly worth knowing about *BEFORE* you do any database design:



Note to Win32 Users: Due to a limitation in the underlying API used by PHP (MS DbLib C API), the length of VARCHAR fields is limited to 255. If you need to store more data, use a TEXT field instead. 



SQL Server natively supports VARCHAR up to 8000 characters.  Note that TEXT fields have substantially poorer performance (and are much more limited) than VARCHAR so you may want to design your databases accordingly...



You can also work around this limitation with the following:



   -- for example, with MyVarCharField VARCHAR(1000)

   SELECT CAST(MyVarCharField AS TEXT) FROM MyTable

This note is for mssql under a Windows environment.



If you are having problems connecting to MS SQL using the mssql PHP extension then I would suggest that you get a copy of the latest NTWDBLIB.DLL. Copy it to the directory where PHP expects to find it's dll files.



I had an issuse whereby I was unable to connect to a MS SQL Cluster and this resolved my problem.

in relation to the "unicode problem" mentioned by andrej at dairyweb dot com dot au I suggest use andrew at power-grid dot com's solution:



if you get a "Unicode data in Unicode-only collation or ntext data cannot be sent to clients using DB-Library (such as ISQL) or ODBC version 3.7 or earlier" error you can use this kind of code (in an MS environment, of course):

<?

$db = new COM("ADODB.Connection");

$dsn = "DRIVER={SQL Server}; SERVER={SERVER};UID={USER};PWD={PASS}; DATABASE={DB}";

$db->Open($dsn);

$rs = $db->Execute("SELECT * FROM table");



while (!$rs->EOF)

{

   echo $rs->Fields['column']->Value."<BR>";

   $rs->MoveNext();

}

?>



hope it helps.

I took the following steps to make PHP talk to SQL2000:



- Copy ntwdblib.dll file from your SQL server's  \winnt\system32 folder to the \winnt\system32 folder on the PHP box.



- Copy the php_mssql.dll from the 'dlls/' directory in distribution package to your windows/system (Win9.x) or winnt/system32 (WinNT, Win2000, XP) directory.



- Add or uncomment the following line under Windows Extentions in your php.ini file (\winnt\php.ini): extension=php_mssql.dll



Hope that helps.

Ok, this took me a few days to get right but for those of you out there having a hard time with getting PHP to talk to SQL 2000 this is for you!  Personally for me the mssql plugin barely worked with sql 2000 and was VERY slow, here's your solution and also some good code to connect securely and quickly through ADO. I was having the worst time getting ADO to work as well, most sites do the driver part a different way.. for me the code below is the only thing that worked.

<?

$db = new COM("ADODB.Connection"); 

$dsn = "DRIVER={SQL Server}; SERVER={SERVER};UID={USER};PWD={PASS}; DATABASE={DB}"; 

$db->Open($dsn);

$rs = $db->Execute("SELECT * FROM table");



while (!$rs->EOF)

{

    echo $rs->Fields['column']->Value."<BR>"; 

    $rs->MoveNext(); 

}

I'm running apache 1.3.26 and php 4.3.6 on a linux server (debian), and connecting to SQL Server 2000 via php4-mssql and Freetds.



I managed to get a connection to the SQL server, but found that when I used the function mssql_query() to pass in a Select statement containing datetime columns, I would get the following message in Internet Explorer - "The page cannot be displayed".  When I removed the datetime column from the query, it worked fine, and returned a resultset.

Looked in the apache error.log file, and found the error "child pid xxxxxx exit signal segmentation fault".



After a lot of searching on the internet I stumbled upon an entry which was missing from my php.ini.  I added the line "mssql.datetimeconvert = Off" to the MSSQL section of pphp.ini, restarted Apache, and the problem went away.  Now I can select dates in SQL queries

if you are having problems with freeTDS, or like me you are trying to get access to unicode data from mssql.



try http://odbtp.sourceforge.net it is cross platform and (reportedly) faster than freeTDS. it is very stable and easy to configure.



i was originally trying to solve an error message of "Unicode data in Unicode-only collation or ntext data cannot be sent to clients using DB-Library (such as ISQL) or ODBC version 3.7 or earlier" and found this solution.



hope it helps someone.

Here's something that could save you 2-3 days research trying to figure out:



<?php

putenv('TDSDUMP=/tmp/tds.log');

putenv('SYBASE=/usr/lib/freetds');

putenv('TDSVER=70');

?>



If you have problems getting the mssql functions to work try these varibles. MSSQL/PHP has problems dealing with different tds versions. 7.0 seems to work well with our server version, maybe a different version would work better with yours.

pmfa at versenet dot com
28-Apr-2004 12:26


If you're going to use freeTDS just to access mssql databases, supply the "--enable-msdblib" switch to the freeTDS configure script when building the library. This will fix some obscure problems, like the month in a date not being displayed correctly, more information in http://www.freetds.org/userguide/config.htm.

there's no documentation of the php.ini option mssql.secure_connection.



so i have here a MS SQL 2000 Server with Windows Authentication and a Windows 2003 Server with IIS 6. So it is clear that i cannot use the usual handling of a mssql_connect. 

I turned the mssql.secure_connection on.

I let the Windows IIS to run under an Service Account(normal user account without any special rights) in a Windows Domain, so i do have a authenticated connection to the SQL Server...



Everything works fine without any rewrite of the code...
