Running a debug build rather than a release build would yield actual file name, class name AND line numbers for where the exception exactly gets thrown; from there it is a matter of seconds to pinpoint the problem.

Hi,
I have two MySQL servers.. one is sourceMySQL and targetMySQL.
I want to update all the tables but WITHOUT the data on the targetMySQL using sourceMySQL without having to do it one by one so it will only update the table structure...
Is there anyway to say:
UPDATE all table structure IN targetMySQL FROM

Your best bet would be to get a copy of MySql workbench MySQL Workbench Downloads[^], then under Server Administration -> Data Dump -> Advanced Export Options, you can select the No Data option, and this will give you a script which will contain all the Create Table statements for the selected database, without data. You can also select to include all stored procedures in the same script.
Hope this helps

Suppose in my SQL2005 database accounting is used in LAN, their copy two files: data1.mdf and data1_log.LDF another folder and renamed data2_log.LDF data2.mdf and, then, di transfer these 2 files into the same directory that contains the original accounting database when attach data2.mdf file into SQL2005 error: Can not attach a database with the same name as an existing database there. While I have renamed then why not attach files? want to attach the data file do?
|
|
|
|
|
let me guess, you rename it from windows explorer, am i right?
it's okay, before you're going to press ok (proceed attach), at top of the form, there's "Attach As" column, change your database name below, good luck!

Seriously you are going about this completely the wrong way, you are treating SQL Server like a single user database IT IS NOT. To transfer databases you need to use the database tools NOT the windows explorer copy/paste.
Stop, close down all your DB stuff and do some learning about SQL Server first, not by trying to use what little you know but by getting a book and studying it or work through some examples, try SQLServerCentral.com they are specialists in this area.

assuming you have 2 SQL2005 database: data1 and data2, I Copy stored procedures from data2 to data1 why not? I want to copy stored procedures through other databases you do?
|
|

I assume each database has the same table structure so the stored procedure will actually work!
You need to create a script of the stored proc and run the script in each database. Using SSMS right click on the procedure and script as create to a new query window. Then change databases and run the script.
Lean how to use the Management Studio!

Which just reinforces my comment on the above thread, you have no idea what you are doing, get a book and do some reading on how databases work.

Hello,
I have 2 SQL servers (MS SQL and ORACLE).
I an running an update openquery (from MS SQL) in order to update a table from Oracle.
My select from openquery is not based on a simple select from one table; it is using few inner joins among tables from both servers.
When I am runnig the update I receive the following error:
<b>ROW-00009: Cannot update row in a read-only rowset ]</b>
As far as i read on the net, I saw that there is not possible because of too complex code.
Does anyone have any idea if there exists any workaround for this?
Thanks a lot.

How about doing those inner joins, and put the result in a temporary table? That way you'd have a "simple" table to update.
That way you'd also see whether the error is in the query itself, or during the update.

Hello Eddy,
Thanks for reply me. In the end, my update should be in a final table and this means to have also a join between the final table and the temporary one but this makes me thinking to try using a view for entire join selection and use it into the openquery.
I will try this and let you know.
Cheers,
Mikcutu.

hi
i have a program with c# and sql server 2005.
i should install it on some stand_alone computers.
For reporting i need to integrate these DB's data into one DB. I need a simple solution for a simple user to do that. could you give me a solution???

No
There is no simple solution, either designed you application incorrectly or are in way over your head.
You need to look into Replication or data wharehousing (although I doubt this applies) and your data need to be structured to support integrating it into 1 DB.

Simple users aren't allowed near the database.
Your easiest way out is to include an extra field in each table, called "DatabaseName". Next, change every sql statement to only update the data where that field matches your current client. It's not optimal, but it would allow for multiple databases to be stored in a single database-file.

I have the same database on different computers, with different raw data of any department, but structures and tables are the same. i have no network, i wanna bring these data toghether for reporting. for example I have these DB's:
database 1 : person1 , persson2
database 2 : person3 , persson4
database 3 : person5 , persson6
and I need this for reporting:
General Database: person1 , persson2, person3 , persson4, person5 , persson6

Same applies; if you had a field called "database", you could drop them all in the same structure.
Small example;
EmplyeeTable
Id Name OtherStuff
1 John Bla
becomes;
EmplyeeTable
Id Name OtherStuff Database
1 John Bla Customer1
That way you could select everything from that customer, even if there's more than one customers data.

Hi,
Can the following be used in a stored procedure?
convert(float, (columnname))like @x
I've tried it. It works.
Wanted to know if it's a good way of programming?
Cheers
Berba

As you will be converting the value of each item in columnname to float, this is a more expensive operation than converting the value in @x into the appropriate type.
|
|
|
|
|
And then they're converted to string, which is worse. 
|

berba wrote: if it's a good
Most likely not; all those conversions will kill you. What are you trying to do? Perhaps you want BETWEEN?
As mentioned, converting the parameter value (once) is much better* than converting all the values in the column.
* Anecdote: I once inherited maintenance of a batch program that took forty minutes to run; after fixing the conversions it took only ten minutes.

Hi,
Can any one tell me how to run a job in oracle which take all the data from one table(for ex: name,address,lastlogintime,etc) and generate output in excel format and save in one common folder everyday.
If you have a sample code, could you share it please, it would be helpfull in understanding the concept better.
