Match only entire words with LIKE?

So 'awesome document' LIKE '%doc%' is true, because doc is a sub-string. But, I want it to be false while 'awesome doc' or 'doc awesome' or 'awesome doc awesome' should be true. How can I do with with a like?

I'm using sqlite, so I hope I don't have to use something that isn't available.

Solution 1:

How about split it into four parts -

[MyColumn] Like '% doc %' 
OR [MyColumn] Like '% doc' 
OR [MyColumn] Like 'doc %' 
OR [MyColumn] = 'doc'

Edit: An alternate approach (only for ascii chars) could be:

'#'+[MyColumn]+'#' like '%[^a-z0-9]doc[^a-z0-9]%'

(You may want to take care of any special char as well)

It doesn't look like, but you may want to explore Full Text Search and Contains, in case that's more suitable for your situation.

See: - MSDN: [ ] (Wildcard - Character(s) to Match) (Transact-SQL)

Solution 2:

you can just use below condition:

(' '+YOUR_FIELD_NAME+' ') like '% doc %'

it works faster than other solutions.

Solution 3:

WHERE (@string LIKE 'doc %' OR @string LIKE '% doc' OR @string LIKE '% doc %' OR @string = 'doc')
