how to set default null to an int column

I want the parentId to have the default Null, how to do that

export const comments = mysqlTable(
  'comments',
  {
    id: serial('id').primaryKey(),
    authorId: int('author_Id').notNull(),
    parentId: int('parent_id'),
});

export const comments = mysqlTable(
  'comments',
  {
    id: serial('id').primaryKey(),
    authorId: int('author_Id').notNull(),
    parentId: int('parent_id'),
});

that's already the default isn't it? https://orm.drizzle.team/docs/column-types/pg#constraints--defaults

It seems like it's not

tacomanator•16mo ago

are you sure you're not passing a blank string value when inserting? what happens if you add

.default(sql`NULL`)

.default(sql`NULL`)

to the column def?

i added this .default(sqlNULL). no type error occurs, im pretty sure that im not passing a blank string value,

One more thing that, createAt has Null default where i shouldnt be. createdAt: timestamp('created_at').default(sqlCURRENT_TIMESTAMP),

Did you check the log to see the SQL being generated for insert? https://orm.drizzle.team/docs/goodies#logging

Two options:

parentId: int('parent_id').default(sql`NULL`)
// or
parentId: int('parent_id').$default(null)

parentId: int('parent_id').default(sql`NULL`)
// or
parentId: int('parent_id').$default(null)
