RE: Data Type to store Leading Zero(0)

[Kanninen Anssi EXT <Anssi.Kanninen@xxxxxxxxx>]

Hi,

 

How about storing the actual number in TEXT column and adding a separate INT primary key column where you either copy the number or use it as a generated column?

 

Or, if you actually want to include the leading zeroes in the primary key, how about two-column primary key like this:

number_of_leading_zeroes  smallint,
the_number                                integer

 

So, the number "0005556879" would become a primary key (3, 5556879).

 

Sincerely,

Anssi Kanninen

Use datatype smallint(1) for storing zero or use Boolean datatype.

Hello Experts,

 

As per business needs we need to store Zero(0) in primary key column of table  with this kind of value à  07******** with applications written in Java microservices.

 

We are not able to use numeric data type as it trims the Zero value in leading, but it’s also a performance impact if we define varchar in the data type.

 

Please suggest.

 

Thanks
