What is TDS Protocol Version 8.0 and why should I use it?

阅读更多关于 What is TDS Protocol Version 8.0 and why should I use it?

问题 I've been using FreeTDS with 8.0 protocol for some time to connect to a MSSQL Database, and things have worked great. But, recently, things started to not work so great. I'll spare the details. So we decided we needed to know a bit more, and I am a bit confused by the following: Does FreeTDS support Microsoft servers? Yes. Microsoft servers don't usually accept TDS 5.0 connections. Use one of versions 4.2, 7.0 or 8.0 of the protocol. See the User Guide for details. User Guide [No mention of 8

阅读更多关于 linux环境php调用sqlServer2000存储过程遇到的问题

　　在linux环境中用php查询sql server并不是很常见的需求.一般来说如果一定要用sql server,编程语言我会先c#;如果一定要用php,数据库我就选mysql. 　　这几天的开发中,需要从一个非开源的erp系统中获取数据,它使用的数据库是sql server 2000,并使用了很多存储过程.我们要基于这个系统做一些报表类的功能,并把这些功能集成到一个原有的PHP开发的crm系统中.需求来了~ 　　在linux环境中用php查询sql server可以用php自带的 mssql 扩展或 pdo_dblib 扩展,这两个扩展都需要freetds类库的支持. 　　在程序调试过程中我绕了很多弯,把里面几个重点记录一下. 1.tds版本设置参考自: http://cubist.cs.washington.edu/doc/FreeTDS/userguide/x574.htm 我用的是sql server 2000,tds版本应该设置成8.0 ,修改 freetds.conf [global] # TDS protocol version # 前面不要带分号 tds version = 8.0 调试中发现,如果使用 pdo_dblib 扩展,这个版本设置没有什么影响,设置成几都能运行;如果使用 mssql 扩展,这个版本一定要设置成8.0,否则会报错. 2

After adding a computed column to a table in SQL Server 2005 I am getting the following message on INSERT , only via PHP (using PDO) it's working fine in SQL Server Managment Studio. To ensure I had everything correct I setup a trace with SQL Server Profiler and copy/pasted the INSERT statement into SQL Server Managment Studio. It ran just fine in SSMS, but continues to fail in PHP. Error adding contact: SQLSTATE[HY000]: General error: 1934 General SQL Server error: Check messages from the SQL Server [1934] (severity 16) [(null)] Turns out the problem had to do with the SET parameters.

I've decided to use FreeTDS driver and unixODBC to manage the PDO connection between my LAMP-based app with a remote MsSQL database. unfortunately it appears that the driver doesn't read the freetds.conf file, nor the environmental variables set either directly via server's CLI or specified in php file by putenv() function. now some data: as I ping the server - no packets are lost. as I telnet the server on 1433 port - the connection is established as I use the command TDSVER=7.0 tsql -H >IP< -p 1433 -U username I am prompted to enter password and connection is established. without the TDSVER
