### Describe the Bug

```ts
import { integer, sqliteTable, text } from "drizzle-orm/sqlite-core";
import {drizzle} from "drizzle-orm/sqlite-proxy"

export const usersTable = sqliteTable("users_table", {
id: integer().primaryKey({ autoIncrement: true }),
name: text().notNull(),
createdAt: integer({mode:"timestamp"})
});

const db = drizzle(async (sql, params, method)=>{
console.log({
sql, params, method
});
return {
rows:[]
}
}, {
casing: "snake_case",
schema: {
usersTable
}
})

await db.query.usersTable.findMany()
```

When executing the code, the expected output case style is snake_case.

The actual output is:

```js
{
sql: "select \"id\", \"name\", \"createdAt\" from \"users_table\" \"usersTable\"",
params: [],
method: "all",
}
```

where "createdAt" was not converted to "created_at".
