Once you have found the file, you will understand where the default folder is. Just as a test, after your program which creates the table and puts a row into it is finished, write another to check that the table you created is still there. If it is, then the file definitely exists somewhere. Simon. ___ sqlite-users mailing list sqlite-users@mailinglists.sqlite.org http://mailinglists.sqlite.org/cgi-bin/mailman/listinfo/sqlite-users

Hi Simon, Thanks for your response. I'm using the node.js plugin. I've tried creating a table then closing the db, and the queries executed successfully, but I was not able to find the database file that it created. I searched the folder structure and was unable to find any .db file, even though the db was opened, a table was created, and the db was closed again.

If you write code to create a new database (open a filename, do at least a CREATE TABLE command, close the connection) what directory does it put the file in ?

[sqlite] Error when reading from pre-populated SQLite database in Ionic project
I'm receiving an error when I try to read from a pre-populated SQLite
database: `sqlite3_prepare_v2 failure: no such table 'plant'`
From what I understand SQLite looks for the mydb.db file in the /www folder
by default, then creates an empty database when it doesn't find the
pre-populated mydb.db file. This is why it can't find the 'plant' table,
because the newly created blank database obviously doesn't contain a
'plant' table. However I can confirm that the database *is* in the /www
folder, and that it contains the 'plant' table when I run `sqlite3 mydb.db`
then `.tables` in the terminal.
I can't figure out why it's not reading from the pre-populated mydb.db file.
Folder structure (from root):
/src
-/app
--/app.component.ts
/www
-/mydb.db
app.component.ts:
constructor(public platform: Platform, private sqlite: SQLite ) {
platform.ready().then(() => {
this.getData();
});
}
getData() {
this.sqlite.create({
name: 'mydb.db',
location: 'default'
}).then((db: SQLiteObject) => {
db.executeSql('SELECT * FROM plant ORDER BY id ASC', [])
.then(res => {
// Do Stuff
}).catch(e => console.log("FAIL executeSql:", e));
})
}
I've attempted many fixes that I've found on StackOverflow, like wiping the
app from my device, starting a new ionic project then copying app and
config files over, and setting a direct path in the database location, but
it still keeps trying to read from the empty database that it creates..
Thanks in advance for any help.

Re: [sqlite] Error when reading from pre-populated SQLite database in Ionic project
Check the results of cordova plugin ls
A common pitfall is that you have to use cordova-sqlite-ext plugin to get
pre-populated database functionality. Commonly used cordova-sqlite-storage
plugin does not support this feature. Second pitfall is if you have
multiple Cordova sqlite plugins installed.

Re: [sqlite] Error when reading from pre-populated SQLite database in Ionic project
When SQLite creates an empty .db file, which directory is it in? With all
your tweaking, etc, is the new database always in the same directory?
Thanks,
Chris
