This is not a mandatory field and is only available when you are getting data from the table or when the select option is selected from dropdown].
5. Limit button.
This button helps you to limit the amount of data that you get from the BlupSheets database. For example-suppose, you have student data in your database and you only want to get data of any five students this can be done with this button. 
This button is also not mandatory to provide and is only present if you have selected the select value in the dropdown. Since you know all the functionality of the BlupSheets node. Now let see how to perform the different operation in database. For this, we are going to add some dummy data to the BlupSheets database. From the above picture, you can see we have added some students to the database.
Since you know all the functionality of the BlupSheets node. Now let see how to perform the different operation in database. For this, we are going to add some dummy data to the BlupSheets database.

Getting data from blupSheet
Suppose you want to get the list of students whose marks are greater than 65%. Let see step by step all things that you need to do to achieve this functionality.
Step 1. Get blup sheet node from the arsenal in blup lightning.
Step 2. Click on add/plus icon next to the table in node. This will open a dialog box that shows you all, the tables that are present in your database then select the table from the database from which you want to get data [Note multiple tables and also be selected].
Step 3. After that click on add/plus icon next to select [second button in node] and select the column which you want to get as output for example in our case student name and student roll number.
Step 4. Now it's time to apply our condition in your case it is students whose marks are greater than 65% for what click on plus/add icon next to where [third button in node]. A dialog box will open where you have to put information like column operator and argument
For example - In your case the value of the column will be student marks, an operator will be greater than and the argument will be 65.
Voila, we are done with all the steps. But if you want more control over the data that you are getting you can use the order by and limit field.
For example - if you want to get student data by their marks and order by department like engineering, you can use the order by button for that juts click on plus/add button next to order and then select the column.
Similarly, if you want to get the only top 5 students then you can use the limit, just click on add/plus icon next to the limit and enter the 5.
That’s it.
