Hi Mukesh,

you have posted your post in wrong category....

Mukesh can you upload your error log for better understanding and as per i understood your question you want to validate the database insertion at serverside and are you trying it for custom table or built-in table?

Hi Mukesh,

Write a Finder method By Name OR a Dynamic Query on your server side.

Check the name passed from the UI against those available in the Db.

Based on the data returned by your method, You can choose to Save the value in Db OR Skip saving.

Hope this helps.

The same way goes for the client side too..fetch the list and compare them with the inputted values...and based on this you can check duplicity..

Hi Mazhar Alam,

Thanks for suggestion. But how i can write the jdbc connection code in javascript . Because we have to compare the input data with data which is available in database.

I am not sure whether it is possible to write the jdbc connection code in javascript . Can you please answer me.

Hi,
I dont think you can write javascripts for jdbc conn..that wont work..instead
-create a class then fetch the database values and then call it in your jsp page...then compare

Hi Mazhar Alam

Ya you are right . creating a class then fetching the database values and then calling it in your jsp page...then comparing . then it will be server side .Am i right ?

Hi Mukesh,
You cannot achieve this in client side.Since client codes are executed by the Browser and not by the Server.You will have to make a call to DB, fetch the values, then compare and then perform your logic.

Hope this helps,
