Prisma - differences between id, unique, and index
Hey 👋,
Could someone explain the difference between
@id, @unique, and @index?15 Replies
Id is they way to say to prima that the field is the
table primary key
Unique is saying that the column value will be unique for the entire table
Index is saying to prisma to create a indexI see, so
@id will make it the field the primary key, @unique, will just mean that postgres won't create that new row unless that value is unique within that column, and @index just creates an index? 👀Unknown User•3y ago

Also that
Yes
You also have new variations of find unique, but it's more related to prisma
In general, adding index randomly isn't good

Adding indexes can make faster queries
But too much indexes can slow down overall the queries

Database indexes are a beast on its own
Uniques are fine
It's more of a constraint

Find unique searchs for index values, such as IDs and unique fields
As they are easily to index and such

Find first is just a general purpose single row search
Depends on the schema and such
Adding indexes without some info about the acess
It's no good

@index just creates a general index for faster lookups by that field.
@unique creates a unique index that not only does faster lookups, but also enforces that two rows cannot have the same value for that fieldUnknown User•3y ago
