来自主题: Database版 - question on SQL Server
I have several questions about the use of SQL Server. Hope
there is some guru
can give me a hand.
1. If I want to do jdbc connection. What type of jdbc do I
use? I know that jdbc-odbc
bridge is free. But seems it has many restrictions, like I
have to install ODBC and
client library on each client machine, and also some of the
untrusted applet can't
visit the DB.
But I heard that other 3 types jdbc connection's drivers are
all commercial and not
free for download. Is that true? I'd like to try if

我用ASP处理ACCESS数据库。

I have an SQL server database host on the server. And I have a tiny Access
application, which just includs some reports, base on those SQL server tables.
I used link table in the Access.
The problem is, to use link table, I need to set up ODBC for the SQL server. I
set it up on the computer that SQL db is hosted. Both Access application and
the SQL server are on network. I want to open the Access application from
another computer in the network, but I got error that says "ODBC - connection

来自主题: Database版 - DSN-less connection to SQL server
As what I know, ODBC is the only way for connection between SQL Server and
Access. Even you set up a connection string, Access still askes you for the
ODBC information including UID and PWD.
My suggestion is: set up a system DSN without login information, for all
users. When user uses access, it will ask user to input the login information.

报错说: Operation must use an updateable query
我上网查了查是说:
Operation must use an updateable query
具体错误如下:
Microsoft OLE DB Provider for ODBC Drivers error '80004005'
Database Error:[Microsoft] [ODBC Microsoft Access Driver] Operation must use a
n updateable query.
这是更新 Access 数据库常见的错误,大多是由权限的问题引起的。我们知道 Access 数
据库是基于文件的,也就是说,通过
ASP 对 Access 的任何修改必须在权限允许的情况下才能进行。
解决方法:
进入 Access 数据库所在的文件夹(目录),在文件夹的权限中,设置 IUSER_ComputerNam
e 的权限为 'Change' 。在数据库文件
的权限中,也要这样进行设置。
可是还是不会改,在那里改?用什么软件改?
第一次接触,不好意思:) 多谢多谢!

What JDBC driver did you use?
If JDBC-ODBC bridge, check if ODBC data source is setup properly.
If Type4 JDBC driver, check if the jar files for the driver are

来自主题: Database版 - 数据库问题一问
First, you need JDBC driver for MS Access or
ODBC driver combined with ODBC-JDBC bridge.
With JDBC, you can write a java program that
would extract data from Access files.
And then, you have two options:
1. Use Oracle JDBC driver to write a java
program that would dump the data into Oracle.
Use java.util.Timer to schedule to your two
java programs to run.
2. Load your previous extraction java program
into Oracle as stored procedure. Write a PL/SQL
store procedure inside Oracle that would dump

I think the easiest way is use access as you have ODBC
or .net, java, asp, coldfusion, php.
or informatic, pervasive.......
As you can connect through ODBC,
For oracle, you can install oracle client then use TOAD(not free) or SQL

For sql server, install one on your pc
For mysql, use TOAD(free)

use ODBC based tool or fast export to write data into file (named pipe under
unix) and import to Oracle using build loader such as SQLLoader.
The benefit of using ODBC tool is it is simple and easy to migrate. Fast
export for Teradata is very very fast.
SQLLoader for oracle need some tuning of the table and infrastructure

You can also use build insert (nolog no redo no undo) mode for oracle stack

Thanks. So this refers to a programming language.
I remembered, we used ODBC database, my boss used to design the query with
Access to perform the functions with excel, so he was using the SQL
programming language as well?
Also, linking with the ODBC, it manipulate data on what database? I saw "MySQL, SQL Server, Access, Oracle, Sybase, DB2, and other database systems", which one I should take a look?
