I have a table that stores sensor data (in SQLite) and looks like this;
TABLE Timestream: idTimestream PK autoincrementing integer, time int not null, value float not null, idSensor integer not null FK
Some but not all sensors have matching times, but I'll only be considering those that do. What I want to do is rearrange the table into the following format,based on a set of sensors listed in the query, not whole set from the table:
Time Sensor1 Sensor2 etc.
I was thinking of Creating a temporary table and then inserting time and the first column, then doing a join on the time for subsequent queries, and finally selecting the whole lot. This doesn't sound too efficient though and I was wondering if there was a better way?
