When it comes to Drizzle โ weโre a thin TypeScript layer on top of SQL with
almost 0 overhead and to make it actual 0, you can utilise our prepared statements API.
When you run a query on the database, there are several things that happen:
all the configurations of the query builder got concatenated to the SQL string
that string and params are sent to the database driver
driver compiles SQL query to the binary SQL executable format and sends it to the database
With prepared statements you do SQL concatenation once on the Drizzle ORM side and then database
driver is able to reuse precompiled binary SQL instead of parsing query all the time.
It has extreme performance benefits on large SQL queries.
Different database drivers support prepared statements in different ways and sometimes
Drizzle ORM you can go faster than better-sqlite3 driver.

Whenever you need to embed a dynamic runtime value - you can use the sql.placeholder(...) api
