import { type QueryParameter } from "https://deno.land/x/sqlite@v3.9.0/mod.ts";
Possible parameter values to be bound to a query.
When values are bound to a query, they are converted between JavaScript and SQLite types in the following way:
JS type in | SQL type | JS type out |
---|---|---|
number | INTEGER or REAL | number |
bigint | INTEGER | number or bigint |
boolean | INTEGER | number |
string | TEXT | string |
Date | TEXT | string |
Uint8Array | BLOB | Uint8Array |
null | NULL | null |
undefined | NULL | null |
If no value is provided for a given parameter, SQLite will default to NULL.
If a bigint
is bound, it is converted to a
signed 64 bit integer, which may overflow.
If an integer value is read from the database, which
is too big to safely be contained in a number
, it
is automatically returned as a bigint
.
If a Date
is bound, it will be converted to
an ISO 8601 string: YYYY-MM-DDTHH:MM:SS.SSSZ
.
This format is understood by built-in SQLite
date-time functions. Also see https://sqlite.org/lang_datefunc.html.
