Update using Query Builder
You can create UPDATE queries using QueryBuilder.
Examples:
await dataSource
.createQueryBuilder()
.update(User)
.set({ firstName: "Timber", lastName: "Saw" })
.where("id = :id", { id: 1 })
.execute()This is the most efficient way in terms of performance to update entities in your database.
Raw SQL support
In some cases when you need to execute SQL queries you need to use function style value:
await dataSource
.createQueryBuilder()
.update(User)
.set({
firstName: "Timber",
lastName: "Saw",
age: () => "age + 1",
})
.where("id = :id", { id: 1 })
.execute()This syntax doesn't escape your values, you need to handle escape on your own.
