multiple update using prisma client (feat. mongodb)

When updating multiple entities in a row using Prisma ORM with a MongoDB connection, you have a few options depending on your requirements:

  1. Using updateMany for Bulk Updates
    If you want to update multiple documents that match a specific condition, you can use updateMany.

    const updatedUsers = await prisma.user.updateMany({
      where: { isActive: false },
      data: { isActive: true }
    });
    
    console.log(updatedUsers);
    

    This updates all users who have isActive: false and sets them to true.

  2. Using update in a Loop for Different Data
    If you need to update multiple entities with different data values, you can use a loop:

    const usersToUpdate = [
      { id: "user1", name: "Alice Updated" },
      { id: "user2", name: "Bob Updated" }
    ];
    
    for (const user of usersToUpdate) {
      await prisma.user.update({
        where: { id: user.id },
        data: { name: user.name }
      });
    }
    

    This performs multiple individual updates, but they are not batched.

  3. Using prisma.$transaction for Bulk Updates
    If you need to update multiple records in a single transaction (to ensure consistency), you can use prisma.$transaction:

    const updates = usersToUpdate.map(user =>
      prisma.user.update({
        where: { id: user.id },
        data: { name: user.name }
      })
    );
    
    await prisma.$transaction(updates);
    

    This ensures that all updates succeed together or fail together.

  4. Using prisma.$runCommandRaw for MongoDB-Specific Bulk Updates
    Since Prisma supports MongoDB natively but doesn’t have full batch update capabilities like SQL-based databases, you can use prisma.$runCommandRaw for MongoDB's native bulk update operations:

    await prisma.$runCommandRaw({
      update: "User",
      updates: [
        { q: { _id: "user1" }, u: { $set: { name: "Alice Updated" } } },
        { q: { _id: "user2" }, u: { $set: { name: "Bob Updated" } } }
      ]
    });
    

    This is a lower-level approach but more efficient for batch updates in MongoDB.
