Complete mySQL Database Backup!!!

I guess I still don't understand your use of the word schema: Do you want a SQL Script or a diagram?

Expand the node for the database, click Database Diagrams. If you haven't created one before, Management Studio will prompt you to to create the support objects required for diagramming. Right-click Database Diagrams and choose New Database Diagram. From here, select the tables you want in the diagram and click Add. Click Close when you've finished adding tables to the diagram.

Management Studio now arranges the tables so that the key relationships don't cross each other.

Note that key relationships are only shown where you've actually defined a FOREIGN KEY relation between tables. They're normally shown as one-to-many, unless the relationship is between the primary keys at both ends, in which case they're shown as one-to-one.

Stability. What an interesting concept. -- Chris Maunder

Hello,

Do any body have idea of getting complete database backup of mySQL database except this?
SELECT * INTO OUTFILE Path FROM Table

I want just there should be only one backup file of All tables and how to restore that. I am using:

you must use it with SHELL commands
i don't know what is this command in VB exactly.but you can search in MSDN for shell.

shell commands are Command Prompt console for executing commands.

i searched for you and i found these:

Why dont you try using MySQL Administrator utility? Its a a free utility available on www.mysql.com. It can perform backups and restores from a graphical interface, and also schedule backups.
"MySQL Administrator is a program for performing administrative operations, such as configuring, monitoring and starting and stopping a MySQL server, managing users and connections, performing backups, and a number of other administrative tasks."

Thanks for your suggestion, actually as i mentioned i am using VB 6.0 as front end and mySQL 4.1 as back end. i want there should be an option for taking the backup of complete database from VB form:
user just tell the path where he wants to take backup of database.
any suggestions?
Thanks and Regards,
Javed

Re: Java function code to SQL Server function

I can see you've just not translated some Java properly. You should also be aware that Java and SQL are different language types. Java is procedural (i.e. you specify the procedure you want it to take) where as SQL is, for the most part, declarative (i.e. you specify what you want and it figures out the details) - but SQL can also operate in a procedural way also but that is often very inefficient. The procedural elements exist only to suppliment the declarative (set based) elements. If you can use a set based operation then SQL is very efficient.

What you are doing here is imposing a procedural model.

Should be

Hi Colin,,Thanks for ur reply..i was changed that function..But here im getting another java code function and i need to translate it into SQL server again..im confused with the for loop in the below code..pls help me..

/* Function will take grid numbers and use lookup array to match the correct OS grid letters */

CREATE FUNCTION searchLetters (let1 bigint,let2 bigint)

Slightly off topic - you don't need bigints because the OS Grid extends only 1.3million metres north to south. (Even if you are using a milimetre scale a regular int would be sufficient)

I don't understand your variable names - what is the input to this function let1 and let2 suggest they are letters, but with a bigint type tells me they are numeric.

What is OSgrid? It looks like a candidate for being a lookup table.

SQL Script

I have written a SQL script to run from my code using executesql command..meaning that i have framed the sql script and have it in a string and i pass the string to the ExecuteSQL funtion which executes my sql script..my scripts functionality is to insert some 1000 rows into a table..when my code executes the script runs(which i came to know from profiler) but the rows are not inserting..

can anyone tell me as wat could be the reason??
NOTE: there are no conditions in the script that ll prevent the insertion happenning

its a bit urgent..

thanks in advance..

Without the script (which will be a bit long) or an error message there isn't much more that we can help with.

If it works in Query Analyser but not through ExecuteSql then the immediate thought that springs to mind is: Do you have any "GO" statements?

GO statements are not part of SQL but a preprocessing instruction to Query Analyser to tell it where to split long scripts up into individual batches - it then sends the smaller chunks of SQL to the server.

On my blog is a demonstration of running SQL via SqlCommand with GO delimiters[^]. If I've guessed your problem correctly it might help.

the script doesnt have any error..

My script is running fine in Query Analyzer and it doesnt have any GO statements..so is GO statement required for my script?? My script will be a maximum of 70 lines thats it..kindly suggest..

any other clues pls let me know..

No. To repeat in brief: GO statements are NOT part of SQL.

Just for another thought, if you are using MSSQL 2000 there is a limit of 4000 characters for nvarchar (unicode 'wide' varchar) and 8000 for regular varchar.
Your string may be longer than that and as a result it gets truncated when passed to a stored procedure.

Re: Need a way to jump to record. [modified]

27-Jun-06 10:29

I'm trying to force a window to jump to a specific row in my database when I click a button. I'm using a "details" display of the table, and there is a binding navigator(supplied with the drag and drop creation of the form).

An example would be (I'm using c# btw)
[Parts list]
1.
2.
3.
...

Select Part [2.]
New Form with more details on part 2.
Edit/Delete/New part

I can use a modified SQL query to return just the one row, but then the add/delete/new buttons dont work because the mapping is lost to the original data. I can't imagine this is something hard to do, but I've been all over the net posting for an answer and nobody has even attempted. Any help is appreciated.

Re: Need a way to jump to record.

27-Jun-06 10:41

I found this article here[^]

I've tried to follow because that sounds like my problem, so my code looks like this.

this.tbAdapter.fill(dataSet.tb);
this.dataSet.tb.select();

that still gives me record 1, instead of the one I want. What am I doing wrong?

Hello again PyroManiak,

I took a quick look at the code in the link you gave, and I noticed that the poster in that message was using the IndexOf function, which he said was returning -1. The way I understood his reply post with the answer was that he called select but then called IndexOf after that. This is just speculation, since I haven't tested it yet, but I wanted to ask you if you were calling IndexOf?

If you are and it still doesn't work, could you post the rest of your code to do with loading the "edit" form?

Hope that helps.

Sincerely,
Alexander Wiseman

I'm trying things like datagridview.rows.indexof();

but it says I must give it a variable, well, if I had the variable I wouldn't need it to tell me! =P

I wasn't being rude. I mistook that initial vagueness of your initial post as betraying a level of understanding below that which you had. If you thought it rude of me to suggest buying a book on that assumption then there isn't much more I can do.
