Restrict Inserted Record values on Table-Level

[Ronan]

Hi, is it possible to restrict data input values on table level?

I have two fields in my table, say: Date1 and Date2. I wanted to make the data entries where Date2 is always greater than Date1. Would this be possible.

 

Thanks in advance

Hello @Ronan,

 

Yes. This is possible. The only pre-requisites are:

1.) You must have an auto-number field in your table.

2.) Date1 and Date2 should have a DataType of Date/Time.

 

Once these requirements are met, you just need to add a formula field to your table.

The syntax would be as follows:

CASE WHEN

[@field:Date2] < [@field:Date1]
THEN CAST( 'a' + 1 as INT)

END

 

Works for me.

 

Hope this helps.

Hello guys,

 

Do note that you will only be able to create this formula field IF YOUR TABLE IS STILL CLEAN. **No invalid/restricted record exists on your table yet.

 

The line CAST( 'a' + 1 as INT) will definitely cause an error therefore preventing invalid data input.

This means that if you already have data that will cause this error, the database will just NOT let you create this formula field.
