/**
|
|
* Adds a 'where' clause to the query.
|
|
*
|
|
* Calling this method will update only those rows that fulfill a specified condition.
|
|
*
|
|
* See docs: {@link https://orm.drizzle.team/docs/update}
|
|
*
|
|
* @param where the 'where' clause.
|
|
*
|
|
* @example
|
|
* You can use conditional operators and `sql function` to filter the rows to be updated.
|
|
*
|
|
* ```ts
|
|
* // Update all cars with green color
|
|
* db.update(cars).set({ color: 'red' })
|
|
* .where(eq(cars.color, 'green'));
|
|
* // or
|
|
* db.update(cars).set({ color: 'red' })
|
|
* .where(sql`${cars.color} = 'green'`)
|
|
* ```
|
|
*
|
|
* You can logically combine conditional operators with `and()` and `or()` operators:
|
|
*
|
|
* ```ts
|
|
* // Update all BMW cars with a green color
|
|
* db.update(cars).set({ color: 'red' })
|
|
* .where(and(eq(cars.color, 'green'), eq(cars.brand, 'BMW')));
|
|
*
|
|
* // Update all cars with the green or blue color
|
|
* db.update(cars).set({ color: 'red' })
|
|
* .where(or(eq(cars.color, 'green'), eq(cars.color, 'blue')));
|
|
* ```
