php select from mysql where title begins with A (and A alone)

I'm sure this is super easy, but can't seem to figure it out.. I need to select all titles from my database where the tit开发者_如何学运维le starts with A, or B, or C etc. Here's what I've tried so far:

SELECT * FROM weblinks WHERE catid = 4 AND title LIKE 'A'

but returns nothing.. Could someone help me out with this?

Cheers

For titles starting in 'A' use a % after the A

SELECT * FROM weblinks WHERE catid = 4 AND title LIKE 'A%'

For titles with the letter 'A' in it, use % on either side of A

SELECT * FROM weblinks WHERE catid = 4 AND title LIKE '%A%'

For titles ending in the letter 'A', use % before the A

SELECT * FROM weblinks WHERE catid = 4 AND title LIKE '%A'

Basically % is a wildcard. It tells MySQL that anything can be in the location.

For having numbers as the first letter, check out Mark's answer.

The wildcards for LIKE are % and _, where % matches 0 or more characters and _ matches exactly one character.

The existing answers are correct for beginning with A:

SELECT * FROM weblinks WHERE catid = 4 AND title LIKE 'A%'

For beginning with any number you can use the REGEXP operator:

SELECT * FROM weblinks WHERE catid = 4 AND title REGEXP '^[0-9]'

try:

SELECT * FROM weblinks WHERE catid = 4 AND ((title like 'A%') OR (title like 'B%'))

so on and so forth

SELECT * FROM weblinks WHERE catid = 4 AND title LIKE 'A%'

% tells "anything", so it's "A" then anything. Only works with the LIKE comparison operator.
