AI (Auto-Incrementing): Numeric fields can be automatically filled in, with the next highest unused value. There can only be one primary key in a table. In a table of user accounts, though, it might be a username. This might be a simple numeric value, like the auto-incrementing integer fields we covered above. PK (Primary Key): A field (or group of fields) that provides a unique identifier for the records in the table. If you try to add a record without providing a value for this field, it will be rejected. NN (Not Null): When this option is set, the field can’t be left empty. This contains the instructions necessary to re-create a database and insert its data into a database. Sometimes, you might be given or sent a database dump file in SQL format. We’re going to look at two ways you can import both data and database table definitions, as well as how you can create your own database. When DB4S starts, it doesn’t have a database loaded into it. On Manjaro, we use pacman: sudo pacman -Sy sqlitebrowser IMESSAGE DB BROWSER FOR SQLITE INSTALL
On Fedora, you type: sudo dnf install sqlitebrowser To install DB4S on Ubuntu, use the following command (again, note the installation still uses the old name): sudo apt-get install sqlitebrowser You can make sure the command does what you think it’s going to before you hard-code some SQL into your application.
Browse and search for database records. Create, edit, and delete tables and indexes. Import and export tables and data in CSV format. Import and export database schemas, tables, and data in SQL format. For sure the field is not TEXT, I expect Excel is converting the INTEGER field to text because i does not know which of the three possible underlying storage formats is being used. To handle "when" column in the table in question either use SQL and the date and time functions provided by SQLite ( ) or convert the field yourself if they are not available. We use that storage format because it is most compatible with the internal date and time types used in the Qt Framework we employ for cross-platform support. 
The storage of DATETIME data types in SQLite is not fixed, there are three different underlying formats supported, we use the INTEGER format that stores Unix Time (seconds since the Unix Epoch of 00:00:00 UTC). I hope I'm not overlooking something obvious.

My next was may it was in the datatime format of Excel pasting the value in a cell and formatting it as date did decode to a value I would expect it to be.Īnyone know how to decode it? I'm fairly sure it can be, as it appears the the log view in WSJTX shows valid data and time data. Time is UTC time in nnnn form (0000 – 2359) My first suspicion was cabrillo logs had some special data time format, but looking into it, it appears somewhat similar to the SQLite DATETIME data type specfications: Since it is stored as a text string it really could be just about anything. I'm guessing that this is either a number representing some time increment from an epoch, or some binary value written into the string field. So I was expecting for the entries should start with something like 11:29:30 what I see is 1624732770. SQLite DATETIME should be a text string in YYYY-MM-DD HH:MM:SS. The WHEN field in the cabrillo_log_v2 table is classified as having the Type DATETIME. Was looking at the db.sqlite file data from my Field Day activity.
