Is there a way to turn off query parametrization in TypeORM?

Question

I'm using TypeORM with MS SQL Server.

In TypeORM default set up SQL queries, generated by .insert and .update methods are compiling in parametrized queries in SQL.

Is there a way to switch to inlining of data instead of parametrization?

PS I know about possibility of SQL injections in this case, but:

1. my data is validated before being persisted in my code and
2. from tests (we operate with big data sets (5m record with 1 column - integer, 10K records with 30 columns of different data types) that needs to be inserted or based on them, existing rows should be updated) - insert without parametrization works much faster.

Answer 1

You can use this style of inserts:

await getConnection()
  .createQueryBuilder()
  .insert()
  .into(User)
  .values({ 
      firstName: "Timber", 
      lastName: () => "CONCAT('S', 'A', 'W')"
  })
.execute();

And as you are aware, you need to escape anything inserted that way to protect against SQL injection.
