Prisma client DartGrouping
Prisma client groupBy API allows you to group your data by a field or a combination of fields.
The following example groups all users by the country field and returns the total number of profile views for each country:
dart
final groupsUsers = await prisma.user.groupBy(
by: [UserScalarFieldEnum.country],
);
for (final group in groupsUsers) {
print('Country: ${group.country}');
}
Filter records with where
You can filter the records that are grouped by using the where argument:
dart
final groupsUsers = await prisma.user.groupBy(
by: [UserScalarFieldEnum.country],
where: UserWhereInput(
email: StringFilter( contains: 'prisma.pub' ),
),
);
Filter groups with having
You can filter the groups that are returned by using the having argument:
dart
final groupsUsers = await prisma.user.groupBy(
by: [UserScalarFieldEnum.country],
having: UserScalarWhereWithAggregatesInput(
count: IntFilter( gt: 10 ),
),
);
