Database Help

Hey,
how to compare a column data value with another variable using javascript? It would be appreciated with an example.
Regards,

You need to retrieve data from the database first. Have you done that already?

I have already a tables and columns, so I want to update one column in one row (last row added), so how can I put value for this column only?

This is a different question than the original one:

So which one are we discussing here?

The second one cause it is more clear.

In order to compare a column data with a variable, you need to load the data from the database into your JavaScript application. Have you already done that?

I didn’t do that yet, how?

Documentation is the best place to start from:
https://backendless.com/docs/js/data_basic_search.html

This didn’t help me a lot to be honest. I want to set a value to a column in the last row added in the database.

You said you wanted to focus on this question:

The very first step to get this done is to retrieve data from the database. We responded with a link to instructions. And now you’re jumping to a completely separate question.

Please stay on topic so we can resolve at least one of the items.

Regards,
Mark

Okay sorry for changing questions. For example how to use this?
Backendless.Data.of( “TABLE-NAME” ).findFirst()
.then( function( result ) {
})
.catch( function( error ) {
});

I want to get a value from the database in the last row added then compare it with my vatiable defined in the code.

Are you new to programming?
Are you familiar with JavaScript?
