Hi All,
Our company need to save contact details into the PostgreSQL database. I
just begin to learn it, so I got many questions. I am not sure which
data type I should choose for website address, varchar or char. The
website address may be very long, and we also don't want to lose the
speed. Thus, the question is: if we have a large contact database, how
much slowdown or speed up will be expected if we choose variable length
rather than fixed length? Thanks forward.
Best Wishes,
Crystal
