Accessing MySQL From .NET
Jan 5, 2004
Hello all,
We are planning to migrate an application written in Perl + mySQL to .NET + MS-SQL Server. The test machine now has SQL Server running. During the development phase in .NET, we would want to access the mySQL database which is being updated at real time, from the Windows box. This is how I think it has to be done:
1. Use DTS to migrate data from mySQL. Does DTS take care of migrating schema and the difference in data types between the mySQL and MS-SQL? Is there any 3rd party software out there that takes care of the migration without any manual labor?
2. Synchronize the data between 2 DBs by creating some kind of a batch job? If so, whats the best way of doing this?
Instead, is it easier to access the live mySQL database on the Linux box from the .NET code and move the DB only after development in the new environment is completed?
Any help/ideas is greatly appreciated.
TIA

Good Morning
Has anyone successfully used cherry's oledb provider for MYSQL to create a linked server from MS SQLserver 2005 to a Linux red hat platform running MYSQL.
I can not get it to work.
I've created a UDL which tests fine. it looks like this
[oledb]
; Everything after this line is an OLE DB initstring
Provider=OleMySql.MySqlSource.1;Persist Security Info=False;User ID=testuser;
Data Source=databridge;Location="";Mode=Read;Trace="""""""""""""""""""""""""""""";
Initial Catalog=riverford_rhdx_20060822
Can any on help me convert this to corrrect syntax for sql stored procedure
sp_addlinkedserver
I've tried this below but it does not work I just get an error saying it can not create an instance of OleMySql.MySqlSource.
I used SQL server management studio to create the linked server then just scripted this out below.
I seem to be missing the user ID, but don't know where to put it in.
EXEC master.dbo.sp_addlinkedserver @server = N'DATABRIDGE_OLEDB', @srvproduct=N'mysql', @provider=N'OleMySql.MySqlSource', @datasrc=N'databridge', @catalog=N'riverford_rhdx_20060822'

Many Thanks

I have an internal Project Management and Scheduling app that I wrote internally for my company. It was written to use MySQL running on a Debian server, but I am going to move it to SQL Server 2000 and integrate it with our Accounting software. The part I am having trouble with is the user login portion. I previously used this:
PHP Code:
$sql = "SELECT * FROM users WHERE username = "$username" AND user_password = password("$password")";
Apparently the password() function is not available when accessing SQL Server via ODBC. Is there an equivalent function I could use isntead so the passwords arent plaintext in the database? I only have 15 people using the system so a blank pwd reset wouldn't be too much trouble.

Hello,I'd noticed when looking at the prices of hosting ASP websites that it was much cheaper if you useda mysql database instead of mssql so this is the way that I coded everything. I've been using the logincontrol too though so does this mean... 1) that I *need* a mssql database?2) that this database will take up my 1 allocated mssql database with the webhost?3) can I use mysql in the same website; it seems to be working ok with the developer server... Many thanks folks,Adam

Has anyone ever connected to a MySQL DB? If so, did you encounter difficulties? Did you do it through DTS? Can you give me some specifics?

Can anybody see what is wrong with this?
create table transaction
(txn_id int not null IDENTITY(1,1),
txn_date datetime not null,
account_id int not null,
/*txn_type_cd enum('DBT','CDT')*/check(txn_type_cd('DBT','CDT')),
amount double(10,2) not null,
teller_emp_id smallint ,
execution_branch_id smallint ,
funds_avail_date datetime,
constraint fk_t_account_id foreign key (account_id)
references account (account_id),
constraint fk_teller_emp_id foreign key (teller_emp_id)
references employee (emp_id),
constraint fk_exec_branch_id foreign key (execution_branch_id)
references branch (branch_id),
constraint pk_transaction primary key (txn_id)
I'm getting an error when I try and run in, but I can't see what it is!
Incorrect syntax near the keyword 'transaction'.
The code has been generated as mysql, and I am attempting to change it to SQL.
Thank you!

Hello all,
I spent the last two days trying to find an application that can export a mySQL database into msSQL syntax so that I can then use that to just create my msSQL database. I have had no such luck, though I could find a bunch to do msSQL to mySQL.
Please let me know if anyone has one or knows of one that works because I really do not want to hand port my 70 table database from mySQL to msSQL
Thanks in advance,
Anthony F Greco

Hi, I've been coding in C#/ASP.NET for a little while now, but I've only ever used MS SQL.I'm starting a new project at work soon, and our host provides free MySQL databases but charges for MS SQL databases.
What are the pros/cons for each of these databases, and how much conversion would be required in an existing C#/ASP.NET application if I wanted to change from MS SQL to MySQL? I assume the syntax/commands to operate a C# app with MS SQL are different to the ones required to communicate with a MySQL database?
I'll probably stick with MS SQL because it's what I know, but I'd like to get familiar with MySQL as it might come in handy one day.Thanks, any information is greatly appreciated.

Hi
I am a newbee to both php and MySQL.
I was wondering if I could get some assiatance on a matter:
I have a userdatabase in flatfile format. The user info is divided into many files:
First the main file where all the usernames are listed in one column. Then one separeate file for each user, named [username].dat containing their userinfo with encrypted password.
Is there a way I can import all these files (almost 300 of them) into a single MySQL table? If so, could someone please explain this to me in easy terms? Thanks.

I have been running Apache 2.2 and PHP 5.0 with MySQL 5.0 on my XP system. I installed MS SQL today, an I'm unable to connect to the MS SQL server through PHP. When I installed MS SQL I:
added extension=php_mssql.dll to php.ini, and I copied ntwdblib.dll into the windows/system32 directory. I still can't access the server.
The server is running, when I start Windows. I can open the SQL Server Service Manager, and it shows Server: XP-LINUX, Services: SQL Server. I can also open the Web Data Administrator tool at: http://localhost:8080/webadmin/default.aspx, and work with databases. I can open it on port 80, because Apache is using that port.
Anyone know what's up whit PHP?
Thanks in adavance...

My friend has a business website http://www.autonetworkinc.com he is concerned about his hosting. He's wonder if it would be a smart move to have his databases converted from FoxPro to something else. I'm wondering if it would be best to have that foxpro converted to mysql (or any other database program i.e. Cache, or something else) or is foxpro where he should stay?

I was asked to program a site in coldfusion using mssql, but i have only used mysql in the past. i heard mssql has all the functions mysql has, but mysql does not have everything mssql does.. so if i programmed it in mysql, it should work? right?

Hello
I am in the process of convering my code from using MySQL to MS SQL
I have queries of the form:
Code:
INSERT INTO <table> (params) VALUES (values)
ON DUPLICATE KEY UPDATE <param1>=<value1>, <param1>=<value1>... <param n>=<value n>
My question is:
Is there an equivalent syntax for such query in MS SQL?
I am looking for a syntax that does this in a single atomic query.
I can always break it down to 2 queries (select + insert/update), but I will do so only after I know there is no equivalent way for it in MS SQL
Also, is there an equivalent syntax for LIMIT X,Y in MS SQL
for quries in the form:
Code:
SELECT <params>
FROM <tables>
WHERE <conditions>
LIMIT X, Y
any help would be appreciated
Thanks

i have a database in MySQL with approximately 1600 records that must be converted into MSSQL. There are too many converters but they are not free to download. What would you recommend me to do among several solutions like first converting to access or excel and then importing them into MSSQL etc..?
Thanks all in advance.
