update()

Signature

builder.update(values: Partial<T>): this

Always chain .eq() or another filter — without a filter, update() will attempt to update every row in the table.

Examples

// Update a single row by ID
const { data, error } = await massi
  .from('posts')
  .update({ title: 'Updated title' })
  .eq('id', postId)
  .single()

// Update multiple rows
const { data } = await massi
  .from('posts')
  .update({ published: true })
  .eq('draft', false)

RLS

The update must satisfy:

• USING — the row must match the policy for the current user to see it
• WITH CHECK — the updated row must still satisfy the policy

Response

{
  data:  T[] | null,    // The updated rows
  error: MassiError | null,
}
