Must be some directory thing. I've never used it in Java myself. A quick check here shows that you have it right for running from mysql prompt. Java looks for the file starting in the current directory where your code is but mysql looks for the file from the database directory... Still trying to fihure out what would work there if you get it please post and tell us as well.

Hey another one things...

But when i tried the filename = "C:/test.txt"

itz import the data from the database and load it to the text file perfectly..

but whatz special in this is.... there is no test.txt file in the C:/

Actually test.txt file is a created file by using Query

SELECT * INTO OUTFILE in the java program for export data to a file(C:/test.txt)..

When i run the above program...

there is no test.txt file in the C:/....

But when i tried to run the program again... its throwing exception

that C:/test.txt file is already exist... But there is no test.txt file..

i dont know what is happening here...

What to do for it...

plzz explain me....

When you run it first time it creates the file right?
When you run it second time, do you delete that file first?

Ya it is creating a file..... But it is not storing in c:/

i dont know where it is storing......

the file is storing in some other location...

the file is in invisible mode....

the file is in invisible mode....

Let us eliminate all the other possibilities first.

 } catch (Exception e) {
}

is not handling any exception. Change it to

 } catch (Exception e) { 
 
e.printStackTace();
 
 
}
 
 

and run it to make sure the program is not throwing any exceptions

Now also the same result....

i will explain u clearly..

When i want a export data from a database into a text file..

i used the query, SELECT * INTO OUTFILE 'C:/test.txt' FROM TABLE....

there is no test.txt file in C:/..i cant see it...

But when i run the program again, it throwing an exception that
C:/test.txt already exists....

thats what, i came to the conclusion that, the above query creating a file

and exporting the data into that file... but i think that created file is in

invisible mode...

Now i'm trying to importing data from database from a file...

in this i had used the following query...

stmt.executeUpdate("LOAD DATA INFILE \"" + 'C:/test.txt' + "\" INTO TABLE " + tablename + " FIELDS TERMINATED BY ','");

its working perfectly running.... and importing the data from the test.txt file into

the database...

But whats special in this is.... there is no test.txt file in C:/


Can u understand what i'm saying?

Plzz tell me a solution for this....

thanks for replying...

Maybe some blocking as explained here..Wait a minute. I think this is taking the shape of a mysql problem so let me copy your post there as well so you can be able to view replies posted from there and here as well.

yeaaaaahhhhhhhhhhhhhh........

Hai r035198x....

i found the solution for that....

just we have add a LOCAL keyword in the query like this

stmt.executeUpdate("LOAD DATA LOCAL INFILE \"" + filename + "\" INTO TABLE " + tablename + " FIELDS TERMINATED BY ','");

Now itz perfectly working...
