Query parameters about sqlite3

[DjDeveloperr]

Found the problem. It was because the C string's null byte was being included in bind parameter. I'll land fix and make a patch release ASAP

It works! Thank you 🙏🏾

You can bind parameters to a query using the variadic arguments in queryArray/queryObject methods.
See: https://doc.deno.land/https://deno.land/x/[email protected]/mod.ts/~/Database#queryArray (the ...args parameter).
For example:

db.queryArray<[string]>("select name from users where id = ?", id);

I'll add some examples to docs and test cases for it 😄

Thanks for the new documentation!

I've attempted using .queryArray and .queryObject multiple times without and get empty results. My database is very simple and essentially lines up to the example you just added to the documentation for binding parameters. I've triple-checked my stuff and can't see what could be wrong. I've retried the same command in the CLI and do get results.

I ran deno test on your module and everything passes, including binding parameters. I don't know what the issue could be.

Deno version: 1.17.1 (release, x86_64-apple-darwin)
Module version: 0.2.3
macOS version: 12.1
SQLite version: 3.37.0

Could you provide a small reproduction for this case? I need something to look into to find out the issue.

It works fine for me:

I tried your the same code that for the users table and it worked fine. However, I'm still having issues with my database not showing any results. Here's the exact SQL and code I use.

import { Database } from "https://raw.githubusercontent.com/denodrivers/sqlite3/main/mod.ts";

const db = new Database("test");

db.execute("CREATE TABLE authors (author_name TEXT NOT NULL, author_username TEXT NOT NULL UNIQUE, author_bio TEXT, PRIMARY KEY (author_username));");
db.execute(`INSERT INTO authors(author_name, author_username, author_bio) VALUES ('John Doe', 'john_doe', "I'm John Doe.");`);

console.log(db.queryArray("SELECT * FROM authors"));
console.log(db.queryArray("SELECT * FROM authors WHERE author_username = ?", "john_doe"))

db.close();

Result:

> [ [ "John Doe", "john_doe", "I'm John Doe." ] ]
> []

Ah, it seems that string parameters are failing here. I will look into this right now.

Beautiful!
