How to merge 2 condition into 1 line of SQLite? - sqlite

Question

I tried using AND but it didn't work
This is the original code
getAllFeeds(user_id_fk, start) {
let data = [user_id_fk, start]
// ---------this part here ------------------------------------------------------------
return this.database.executeSql("SELECT * FROM feed WHERE (user_id_fk) = (?) ORDER BY feed_id DESC LIMIT ?, 5", data).then((data) => {
// ------------------------------------------------------------------------------------
let feeds = [];
if (data.rows.length > 0) {
for (var i = 0; i < data.rows.length; i++) {
feeds.push({ feed_id: data.rows.item(i).feed_id, feed: data.rows.item(i).feed, user_id_fk: data.rows.item(i).user_id_fk, created: data.rows.item(i).created });
}
}
return feeds;
}, err => {
console.log('Error: ', err);
return [];
});
}
How do I add this?
SELECT DATETIME(created, '+8 hours') as `add8hours` FROM feed WHERE (user_id_fk) = (?) ORDER BY feed_id DESC;
When I use this last line the result will only show the date time and not the other columns
This is the table BTW
CREATE TABLE IF NOT EXISTS feed (
feed_id INTEGER PRIMARY KEY AUTOINCREMENT,
feed TEXT,
user_id_fk INTEGER,
created DATETIME DEFAULT CURRENT_TIMESTAMP
);

If you want to show some specific columns from a table, you need to separate them by a comma.
Eg (using aliases): SELECT COLUMN_1_NAME as ALIAS_COLUMN_1, COLUMN_2_NAME as ALIAS_COLUMN_2 FROM TABLE_NAME;
So in your case it should be something like:
SELECT DATETIME(created, '+8 hours') as add8hours, feed FROM feed WHERE (user_id_fk) = (?) ORDER BY feed_id DESC LIMIT ?, 5
