The reason you will use SQLite is that it is a file-based database system that is included with Python. For the purposes of this article, you will focus on a very simple one known as SQLite.
SQLITE DATABASE BROWSER FILTER SOFTWARE
Popular database software includes Microsoft SQL Server, PostgreSQL, and MySQL, among others.
SQLITE DATABASE BROWSER FILTER INSTALL
Most database software require you to install complex software on your local machine or on a server you have access to. Databases hold data in a tabular format, which means that they have labeled columns and rows of data. The typical solution for this type of situation is to use a database. More often than not, the data that you work with will need to be available to multiple developers as well as multiple users at once. Note that the date column Zeit must have the format: YYYY-MM-DD HH:mm:ss, otherwise it is not comparable.Software developers have to work with data. | Killergondel | gondolator | TEST | 15:22:58 | | gondolator | TestUser | verdammt? | 15:41:36 | Results: | Sender | Empfaenger | Inhalt | Zeit | ON l.other in (c.Empfaenger, c.Sender) AND l.maxdate = c.Zeit WHEN 'gondolator' = c.Sender THEN c.Empfaenger WHEN 'gondolator' = c.Empfaenger THEN c.Sender WHERE 'gondolator' IN (s.Benutzername, r.Benutzername) LEFT JOIN Accounts r ON n.Empfaenger = r.ID If your SQLite version supports CTEs, you can do it like this: WITH
I used datetime('now') because i actually failed setting it with costum times. INSERT INTO Nachrichten(Sender, Empfaenger, Zeit, Inhalt) Values(4, 1, INSERT INTO Nachrichten(Sender, Empfaenger, Zeit, Inhalt) Values(3, 1, INSERT INTO Nachrichten(Sender, Empfaenger, Zeit, Inhalt) Values(2, 1, INSERT INTO Nachrichten(Sender, Empfaenger, Zeit, Inhalt) Values(1, 4, INSERT INTO Nachrichten(Sender, Empfaenger, Zeit, Inhalt) Values(1, 3, INSERT INTO Nachrichten(Sender, Empfaenger, Zeit, Inhalt) Values(1, 2, INSERT INTO Accounts(Benutzername) Values('TestUser') INSERT INTO Accounts(Benutzername) Values('Jan') INSERT INTO Accounts(Benutzername) Values('Killergondel') INSERT INTO Accounts(Benutzername) Values('gondolator')
Not both.Ĭan someone help me with the correct SQL Statement?ĬODE to Rebuild Tables: CREATE Table Accounts(įOREIGN KEY(Sender) REFERENCES Accounts(ID),įOREIGN KEY(Empfaenger) REFERENCES Accounts(ID)) I now want only the last messages that were send OR received. I join the accounts database to get the Usernames. Group by Accounts.Benutzername, Accounts_2.Benutzername WHERE (Accounts_2.Benutzername = 'gondolator' OR Accounts.Benutzername = 'gondolator') LEFT JOIN Accounts as Accounts_2 On Nachrichten.Sender = Accounts_2.ID LEFT JOIN Accounts ON Nachrichten.Empfaenger = Accounts.ID
SQLITE DATABASE BROWSER FILTER CODE
The code i use: SELECT Accounts_2.Benutzername as Sender, Accounts.Benutzername as Empfaenger, Nachrichten.Inhalt, Nachrichten.Zeit My problem is, i only get the last messages in both ways(get and send). Now i want to filter the data for a specific person so he gets the last messages to each person. It has 4 Columns, the Message, the time it was sent, the person who wrote the message and the person who gets the message: I have a sqlite database in which i store messages.
