Hello
I am a programmer using SQLite3 to create a database for an application. I
have been running into some problems with my SQL queries which I dont think
are correct. Can you check them & correct them where relevant?
Right now only one table exists, its layout is like so:
[quote]
Table = element
2 columns = property TEXT PRIMARY KEY, value TEXT
ie, CREATE TABLE element(property TEXT PRIMARY KEY, value TEXT)[/quote]
Are these queries correct?
Check if property already exists in table:
[code]
SELECT property
FROM element
WHERE property == 'color';[/code]
If I get NULL back that will mean that this property does not exist in the
table? Is this correct?
Change the value in a row where property equals color:
[code]
DELETE value
FROM element
WHERE property == 'color';
INSERT INTO element(value)
VALUE('orange')
WHERE property == 'color';
commit;[/code]
Also I want to create a new TABLE with the name '#element' or '.element' but
I always get an error because of the '#' & '.' characters. Is it possible to
create a table with a '#' or '.' character in its name?
