I have been searching for Oracle functions that are equivalent to to MySql Match Against.
Any help will be greatly appreciated
As a WHERE condition this does not exist but the main advantage when you use MATCH AGAINST is that you use a FULLTEXT index and that exits in Oracle also and is called Oracle Text. See the following answer: Does Oracle support full text search? or make a general search for "Oracle Text".

I want to use a <textarea> tag or an alternative written in JavaScript, that highlights my SQL statements as I write them (effectively the same as phpMyAdmin's SQL section where you can manually write queries.)
Please tell me that this is possible without using HUGE libraries and can be easily customizable. If so, which library should I be using and how?

I think I found what I wanted. Though this looks like a big library, this will do the trick. Thanks everybody.

could anyone help me how to integrate the levenshtein function in an accessdatabase, which I will be query-ing from vb.net later through normal sql statements.
I would like to be able to do a
SELECT levenshtein(colx, 'myinputword') AS dist FROM table WHERE dist < 3
or something like that...
I know on mysql one can create a custom function and call that afterwards, but I have no clue on how to do this in access.
or is this just not possible in access
It is possible to have custom functions in MS Access (UDF), but it is not possible to use the function outside of Access.

thish is a general question about the "big" database player.
I want to know how these DBMS manage deleted record. In particular: does they free space and re-utilize that free space ?
Hope not to be off topic.
Thank you!
In general, they mark a deleted record as deleted, and they keep track of how much free space is available (and where), and will reuse the storage eventually (for new or updated records), but not necessarily in a timely manner.

i need some information about csv extension, what is the use of csv extention, how to use it, any simple example
Here is all you could possibly want to know about CSV.
And if that doesn't satisfy your unquestionable thirst for knowledge, try the references from Wikipedia and Google.
It's just a way to indicate the type of the file, nothing more, nothing less.
Could call the file XXXX.doodleberry for all the operating system or the application using it could care about it.

Whats does "indexing" mean? How it is useful to a web crawler?
Internal indexing in a database and the index that a web crawler looks at are two different concepts.
Indexing in a database is a method to make looking up records by certain columns faster.
Indexing in the context of web crawlers involves storing web pages and building an index based on what's in them so as to access them by content more easily.
