Hello All, I know its possible to create a table that has an index on the side and a search bar at the top that a user can type in to find an item, but is it possible to say to the table if array isEqual to "item1" push view1?

This problem is pretty hard to describe and therefore difficult to search the answer. I hope some expert could share you opinions on that. I have a table with around 1 million of records. The table structure is similar to something like this: items{ uid (primary key, bigint, 15) updated (indexed, int, 11) enabled (indexed, tinyin...

Is there some standard way to name indexes for SQL Server? It seems that the primary key index is named PK_ and non-clustered indexes typically start with IX_. Are there any naming conventions beyond that for unique indexes? ...
I have an application with a rather long chain of upgrade scripts. The application works in SQL Server 2005 - I'm trying to upgrade it so it will also work in SQL Compact 3.5 Part of the script involves dropping old indexes if they exist. I REALLY want to have one script that can handle both scenarios. I've been having a lot of success...
An instance of WordPress that I manage goes down about once a day due to this monster MySQL query taking far too long: SELECT SQL_CALC_FOUND_ROWS distinct wp_posts.* FROM wp_posts LEFT JOIN wp_term_relationships ON (wp_posts.ID = wp_term_relationships.object_id) LEFT JOIN wp_term_taxonomy ON wp_term_taxonomy.term_taxonomy_id = wp_term...

Hello! i need to extract terms with highest frequencies from several lucene indexes, to use them for some semantic analysis. So, I want to get maybe top 30 most occuring terms(still did not decide on threshold, i will analyze results) and their per-index counts. I am aware that I might lose some precision because of potentionally dr...
Hello. I have a homepage, for example: www.example.com. There is a url like this: www.example.com/subdirectory/page.php?var1=A&var2=B It's a long url, so I changed it like this: www.example.com/subdirectory/page/A/B as well as I config the .htaccess file: <Files page> ForceType application/x-httpd-php </Files> Howe...
I'm executing the following query SELECT COUNT(*) FROM table WHERE field1='value' AND (field2 >= 1000 OR field3 >= 2000) There is one index over field1 and another composited over field2&field3. I see MySQL always selects the field1 index and then makes a join using the other two fields which is quite bad because it needs to join 146...

But why not both in one? if ((index = blah.IndexOf(something) >= 0) // i know that Contains is true and i also have the ...
