QUESTION
I have been trying to solve this problem for some time now. I'm writing an application using Swift/SwiftUI and FMDB over SQlite3. When a delete is executed on a table where there are existing foreign keys I expect the delete to fail. It doesn't and there is no error thrown.
In XCode I'm linking with libsqlite3.tbd listed as date modified 03/16/2021. Inside the tbd file I find: install-name: '/usr/lib/libsqlite3.dylib' current-version: 321.3 compatibility-version: 9
I find the libsqlite3.dylib in: /System/Volumes/Data/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/usr/lib Info shows it was created 04/09/2021. No apparent version
What is happening is that I have foreign keys on a table named BudgetedExpense to a table named BudgetDescription.

QUESTION
I'm trying to retrieve the contents of an SQLite database using Dapper ORM and populate a list of objects using it. However, even though I have set the column type in the database to BLOB
, I am getting an error which seems to suggest Dapper ORM is interpreting the data as a string.
The database is being populated with a Python script which is configured with the column also set to BLOB
type. Within SQLiteStudio, I can view the data as an image preview, so the correct data is in the database.
The code to query the database:
...ANSWER
Answered 2021-May-14 at 20:56I've managed to fix this issue by moving from using Dapper to SQLite-Net.
https://github.com/praeclarum/sqlite-net/
Not sure what the issue with Dapper was; the data in my database was always showing correctly so I can only assume Dapper must've been doing something weird to the data when it pulled it from the database and populated the objects.
I've stuck with using Base64 encoding for the binary data, I've not tested SQLite-Net with raw binary data.
QUESTION
I am trying to make two database table and linked them together. Here is my code:
...ANSWER
Answered 2021-Apr-16 at 18:50From SQLite's ALTER TABLE:
The ALTER TABLE command in SQLite allows these alterations of an existing table: it can be renamed; a column can be added to it; or a column can be dropped from it.
This means that with SQLite you can't add a foreign key constraint to an existing table.
Also, there are no varchar
or money
data types (they are interpreted as TEXT
and NUMERIC
affinities respectively), but this is not the source of the error.
In Mysql there is no money
data type.
You can read this thread for an alternative: Best data type to store money values in MySQL
Your code, if you remove the backticks, is valid in SQL Server and Postgresql but not in MySql and SQLite.

I'm new to sql, and i ran the query to create a database
...ANSWER
Answered 2020-Jul-10 at 16:13Since SQLite is a file-level and not server-level DBMS, the command CREATE DATABASE ...
is not supported as there is no server instance to invoke the command.
To create SQLite databases, you would need to create the file beforehand (outside of SQL code) via the CLI executable, sqlite3
, or application layer code (Python, PHP, etc.).
