sql-like

I'm having some trouble searching for any similar match in two fields. For example I have a table with the values: CAR MAKE CAR MODEL Ford Mustang (Shelby) Toyota Corolla Seat Leon etc etc. I want to be able to get the result "Ford, Mustang (Shelby)" by searching for any of the following combinations: Ford Mustang Shelby Ford Mustang or any other combination. Is this possible? I've had a good search but it's hard to find the search terms to describe what I mean. Split your terms on whitespace and then, for each term, build a little bit of SQL like this: car_make like '%x%' or car_model like '

I'm creating result paging based on first letter of certain nvarchar column and not the usual one, that usually pages on number of results. And I'm not faced with a challenge whether to filter results using LIKE operator or equality ( = ) operator. select * from table where name like @firstletter + '%' vs. select * from table where left(name, 1) = @firstletter I've tried searching the net for speed comparison between the two, but it's hard to find any results, since most search results are related to LEFT JOINs and not LEFT function. Your best bet would be to measure the performance on real

$percent = ‘%’; $st=$db->prepare(“SELECT * FROM x WHERE y LIKE ?”); $st=$st->execute(array(‘%’.$percent.’%’)); /*I want to get all records with the string % included like 5% etc.*/ The above example will not match correctly, instead matching all records in table x. In order for this to work correctly, I apparently need to set $percent='\%'. This is where I am left confused about the concept behind prepared statements. I thought the whole point of prepared statements was that the value itself( $percent) would simply be interpreted as a string instead of a special wildcard character. I would

I've a Query. Is there any built-in function or any other method associated with MySQL, which will return rows that contains EXACT word in the database table field? I'm aware that with MySQL LIKE operator, You can search for a specified pattern in a column which will match a string value against a pattern string containing wild-card characters. But With MySQL LIKE clause, It'll return substring entries too. Eg. Suppose 3 column values are like below: 1. "Take another shot of courage" 2. "The End of This age is Not Yet" 3. "Employers can obtain this wage rate by submitting a request" I want to

Could someone explain such a big performance difference between these SQLs ? SELECT count(*) as cnt FROM table WHERE name ~ '\*{3}'; -- Total runtime 12.000 - 18.000 ms SELECT count(*) as cnt FROM table WHERE name ~ '\*\*\*'; -- Total runtime 12.000 - 18.000 ms SELECT count(*) as cnt FROM table WHERE name LIKE '%***%'; -- Total runtime 5.000 - 7.000 ms As you can see, the difference is more than double between LIKE operator and simple regular expression (I thought LIKE operator internally would be converted into the regular expression and there shouldn't be any difference) There are almost

SQL Server has the LIKE operator to handle wildcard searches. My customer wants to use the "*" (asterisk) character in the user interface of an application as the wildcard character. I'm just wondering if there are any standard characters that I need to worry about (that are used as special characters in SQL Server) besides the "%" (percent) character itself before performing a LIKE wilcard search in case their keyword contains a "%" and needs to find a "%" in the actual string. If so, what are they? So please assume that [table1].[column1] will never have a "*" (asterisk) in the text string!
