Prisma, How to query if string exist in another string

Question

I am writing a prisma query but I need to know if a string exist in another string.

In prisma we can do this

  where: {
    id: { in: [22, 91, 14, 2, 5] },
  },

for arrays. but I want to be able to check if the property value exist in a string. Some thing like this

  where: {
    comment: { in: "some random string containing the value in comment" },
  },

So if comment: 'the value' it should match the query above. I can not find a sample of this kind of operation in the prisma doc.

I am looking for inverse of the string_contains function. basically the equivalent of this SELECT * FROM table WHERE POSITION(comment IN "some random string containing the value in comment") > -1

Answer 1

You should be able to use something like string_contains , which works like this:

const getUsers = await prisma.user.findMany({
  where: {
    pets: {
      path: ['favorites', 'catBreed'],
      string_contains: 'Van',
    },
  },
})

I think what you are trying to do can be done by using prisma filtering and sorting function contains .

In your case, it should be looks like:

where: {
    comment: { contains: "the value" },
},

The above query will return you the records that contains the value on comment column.
