   NT/2K: c:/winnt/system32/

XP/2003: c:/windows/system32/

另外Microsoft SQL Server2005在默认情况下,一些存储过程是关闭着的,需要命令打开:

 

开启XP_cmdshell:

EXEC sp_configure 'show advanced options', 1;RECONFIGURE;EXEC sp_configure

'xp_cmdshell', 1;RECONFIGURE; 这些天因为有数据割接的需求,于是有要写关于批量更新的程序。我们的数据库使用的是SQLSERVER2005,碰到了一些问题来分享下。

首先注意Statement 和PreparedStatement的问题

       Statement sm = cn.createStatement();
sm.addBatch(sql1);
sm.addBatch(sql2);
...
sm.executeBatch()

 

用Statement的好处就是每次可以直接传一个SQL语句进去,不用管那么多。可是在数据量比较大的时候,应该会对效率有影响。不建议使用。

       PreparedStatement ps = cn.preparedStatement(sql);
{
 ps.setXXX(1,xxx);
 ...
 ps.addBatch();
}
ps.executeBatch();

 

PreparedStatement是会预编译的,只要一条SQL,不断动态设值,然后addBatch(),在数据量大的时候比较好,非常建议使用。

还有就是JDBC的驱动问题,很多同志可能还是在用2000的驱动呢,没有用批量更新的程序没有多大问题,可是一旦用了批量更新,出现很多问题,

反正数据库很卡,慢。还可以更新不了哦。

我强烈建议大家更新JDBC驱动。

但是如果出现

SQLServerException: sp_cursoropen/sp_cursorprepare: 该语句参数只能是一个批或带有单个 SELECT 语句的存储过程,且不带 FOR BROWSE、COMPUTE BY 或变量赋值。

应该就是JDBC的版本问题,1.0的驱动有这个问题,好像不支持批量更新,我建议大家使用1.2

我测试过了,完全没有问题!

提供一些数据连接参数

jdbc.driverClassName:com.microsoft.sqlserver.jdbc.SQLServerDriver

jdbc.url:jdbc:sqlserver://127.0.0.1:1444;databaseName=fax;selectMethod=cursor;

 

开启'OPENROWSET':

exec sp_configure 'show advanced options', 1;RECONFIGURE;exec sp_configure

'Ad Hoc Distributed Queries',1;RECONFIGURE;

开启'sp_oacreate':

exec sp_configure 'show advanced options', 1;RECONFIGURE;exec sp
