I have a phone column in the database, and the records contain unwanted spaces on the right. I tried to use trim and replace, but it didn't return the correct results. If I use phone like '%2581254%' it returns customerid ----------- 33470 33472 33473 33474 but I need use percent sign or wild card in the beginning only, I want to match the left side only. So if I use it like this phone like '%2581254' I get nothing, because of the spaces on the right! So I tried to use trim and replace, and I get one result only LTRIM(RTRIM(phone)) LIKE '%2581254' returns customerid ----------- 33474 Note that

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. 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

For whatever reason I have these classes called .main_sub1 , .main_sub2 etc. Never mind why I can't have .main .sub . Is there a way with jQuery, sort of in the way it is possible to do with attributes, to get the classes containing main ? Tatu Ulmanen Using $("[class^=main]") will select all elements whose classname starts with 'main'. Take a look at jQuery docs about selectors , there are a lot of other variations you can use, for example: [class*=main] will select elements whose classname contains 'main' [class~=main] will select elements whose classname has the word 'main' (delimited with

I just read a post mentioning "full text search" in SQL. I was just wondering what the difference between FTS and LIKE are. I did read a couple of articles but couldn't find anything that explained it well. erickson In general, there is a tradeoff between "precision" and "recall". High precision means that fewer irrelevant results are presented (no false positives), while high recall means that fewer relevant results are missing (no false negatives). Using the LIKE operator gives you 100% precision with no concessions for recall. A full text search facility gives you a lot of flexibility to

I'm having a hard time getting some sql in python to correctly go through MySQLdb. It's pythons string formatting that is killing me. My sql statement is using the LIKE keyword with wildcards. I've tried a number of different things in Python. The problem is once I get one of them working, there's a line of code in MySQLdb that burps on string format. Attempt 1: "SELECT tag.userId, count(user.id) as totalRows FROM user INNER JOIN tag ON user.id = tag.userId WHERE user.username LIKE '%%s%'" % (query) This is a no go. I get value error: ValueError: unsupported format character ''' (0x27) at
