How to switch the unique constraint on the index when updating two items in Prisma?

edit

To switch the unique constraint on the index when updating two items in Prisma:

1. Update the first item and remove its unique constraint by setting the unique constraint value to null. For example, if the unique constraint is on a field named "name", the code would be:

await prisma.myModel.update({
    where: { id: firstItemId },
    data: { name: null },
})

1. Update the second item by setting its unique constraint to a different value. For example, if the unique constraint was on "name" and the new name is "newName", the code would be:

await prisma.myModel.update({
    where: { id: secondItemId },
    data: { name: "newName" },
})

1. Finally, update the first item again and set its unique constraint to the desired value. For example, if the new name for the first item is "newFirstItemName", the code would be:

await prisma.myModel.update({
    where: { id: firstItemId },
    data: { name: "newFirstItemName" },
})

By doing this, you are effectively switching the unique constraints of the two items.
