[SOLVED] SQLite - Get all results from a table, but mark those who exist in another query


Recommended Posts

Okay, I got the following table

CREATE TABLE IF NOT EXISTS Unchecked
(
    date      DATE,
    filename  VARCHAR(255) PRIMARY KEY,
    download  VARCHAR(255)
);

And I got a huge query, which I'll shorten for convenience ;)

SELECT date, filename, download FROM UnChecked WHERE filename like "[imuR88-KSN]%";

 

This all works nicely, but what I want is everything from the UnChecked table, with the result from the query above having an extra field set to true, or null.. something I can later on use to determine whether they matched the like or not.

I tried creating a temporary table, but it doesn't seem to let me... and I'm quite sure this is somehow possible with a self join, maybe I'll figure it out after a good night of sleep.

 

 

This is what I tried:

CREATE TEMPORARY TABLE workaround( 
    date          DATE,
    filename      VARCHAR(255) PRIMARY KEY, 
    download      VARCHAR(255),
    interesting   BOOL DEFAULT FALSE
);
SELECT date, filename, download INTO workaround FROM UnChecked;
SELECT * FROM workaround;

But that last select comes up blank for some reason. (Was planning on doing a second query to set the 'interesting' boolean to true)

 

EDIT

We're talking about SQLite3 using the PDO driver btw.

Okay figured out one way... although it took me ages.

CREATE TEMPORARY TABLE workaround( date DATE, filename VARCHAR(255) PRIMARY KEY, download VARCHAR(255), interesting BOOL DEFAULT 0 );
INSERT INTO workaround( date, filename, download ) SELECT * FROM UnChecked );
UPDATE workaround SET interesting=1 WHERE filename IN (
    SELECT filename FROM UnChecked WHERE filename like "[imuR88-KSN]%"
);
SELECT * FROM workaround;

 

For some reason using TRUE and FALSE instead of 0/1 gives a nice error... it thinks the TRUE is a column name..

DBO driver didn't show it.. so that took a while to figure out.
