Nova Campo No Db


Guest Bondezan

Question

Guest Bondezan

Pessoal,

Tenho uma tabela Cliente no meu BD e preciso acrescentar mais um novo campo

chamado Desconto no qual apenas 20% dos clientes cadastrados possuirao algum valor.

Eu teria algum ganho de performance se eu criasse outra tabela só para guardar esses descontos? Ou seja 80% dos registros estarão com o desconto zerado ocupando espaço.

T+
