LEFT OUTER JOIN with LIKE in SQLite not working

Question

I think I'm going mad, but in SQL server management studio this query works perfectly well:

INSERT INTO [#Temp_main]
SELECT T1.ID, T2.ID
FROM [#Temp_other] T1
LEFT OUTER JOIN [Table_with_lots_of_data] T2 ON ((T2.ID LIKE T1.ID+'%')

In other words, table Temp_other contains incomplete ID s (only the first few characters), and I want to match these to the ID in Table_with_lots_of_data , and insert the results into Temp_main .

The application I'm writing, which uses SQLite databases, was only returning the T1.ID (ie no complete T2.ID ), so I popped it into the DB browser for SQLite for testing, and lo and behold this also returned only the T1.ID .

Any help as to what I'm missing with SQLite? I'm guessing it's something to do with the T1.ID + '%' wildcard bit?

Answer 1

|| is a concatenation operator is SQLite, not + :

(T2.ID LIKE T1.ID || '%')
