# Raw SQL comparisons (Prisma ORM v7) (/docs/orm/v7/more/troubleshooting/raw-sql-comparisons)

Compare columns of the same table with raw queries in Prisma ORM

Location: ORM > v7 > More > Troubleshooting > Raw SQL comparisons

Comparing different columns from the same table is a common scenario. This page shows how to achieve this using raw queries for Prisma ORM versions prior to 4.3.0.

> \[!WARNING]
> From version 4.3.0, you do not need to use raw queries to compare columns in the same table. You can use the `<model>.fields` property to [compare the columns](/guides/reference-6-v7-reference-prisma-client-reference#compare-columns-in-the-same-table).

## Comparing numeric values

Example: retrieving posts that have more comments than likes.

```prisma
model Post {
  id            Int      @id @default(autoincrement())
  createdAt     DateTime @default(now())
  updatedAt     DateTime @updatedAt
  title         String
  content       String?
  published     Boolean  @default(false)
  author        User     @relation(fields: [authorId], references: [id])
  authorId      Int
  likesCount    Int
  commentsCount Int
}
```

### PostgreSQL / CockroachDB

```js
const response =
  await prisma.$queryRaw`SELECT * FROM "public"."Post" WHERE "likesCount" < "commentsCount";`;
```

### MySQL

```js
const response =
  await prisma.$queryRaw`SELECT * FROM \`public\`.\`Post\` WHERE \`likesCount\` < \`commentsCount\`;`;
```

### SQLite

```js
const response =
  await prisma.$queryRaw`SELECT * FROM "Post" WHERE "likesCount" < "commentsCount";`;
```

## Comparing date values

Example: get all projects completed after the due date.

```prisma
model Project {
  id            Int      @id @default(autoincrement())
  title         String
  author        User     @relation(fields: [authorId], references: [id])
  authorId      Int
  dueDate       DateTime
  completedDate DateTime
  createdAt     DateTime @default(now())
}
```

### PostgreSQL / CockroachDB

```js
const response =
  await prisma.$queryRaw`SELECT * FROM "public"."Project" WHERE "completedDate" > "dueDate";`;
```

### MySQL

```js
const response =
  await prisma.$queryRaw`SELECT * FROM \`public\`.\`Project\` WHERE \`completedDate\` > \`dueDate\`;`;
```

### SQLite

```js
const response =
  await prisma.$queryRaw`SELECT * FROM "Project" WHERE "completedDate" > "dueDate";`;
```
