Breaking changes

• selectNoFrom is removed from ExpressionBuilder due to severe typescript performance issues. selectNoFrom still exists in the Kysely instance, and in most cases, you can use that instead. See this example on how to migrate: https://kyse.link/?p=s\&i=sqAZIvTQktxgXYzHGkqX.
• Types are once again a little bit stricter in some places. You might get type errors from code like where('first_name', '=', sql`something`). You need to explicitly give a type for the sql expressions like this sql<string>`something`
• Deprecated functions eb.cmpr and eb.bxp have been removed. Use eb as a function instead.

v0.26.3

Compare Source

• Type performance improvements. We got ~30% speedup in our type test suite. Results will vary.
• Fix autocompletion issues select(eb => [autocompletion works here now]).

v0.26.2

Compare Source

• Added support for select statements without a from clause. The function is called selectNoFrom. The function name was selected after a lot of discussion. The most natural name would just be select, but new users would find that in a list of autocompletions before selectFrom and naturally use it when trying to create a select from query. This would be especially true for people coming from knex where a select from query is started using a select call. #​605
• Add object variants of and and or functions. Allows easy where(eb => eb.and(object)) filters. #​583
• Add support for tuples. See some examples here. #​611
• Add addPrimaryKeyConstraint for AlterTableBuilder. #​639 Thank you @​n7olkachev ❤️
• Add any function to function module. #​612
• Add between method to expression builder. #​602
• Add lit method to expression builder. #​600
• Add multi-column variant of orderBy. #​423 Thank you @​igalklebanov ❤️

An example of an object and call:

const persons = await db
  .selectFrom('person')
  .selectAll()
  .where((eb) => eb.and({
    first_name: 'Jennifer',
    last_name: eb.ref('first_name')
  }))
  .execute()

select * from "person"
where "first_name" = $1 and "last_name" = "first_name"
