Query by Example (QBE) is a database query language for relational databases. A QBE parser parses the search query and looks for the keywords. A more formal query string, in languages such as SQL, is then generated, which is finally executed. However, when compared with a formal query, the results in the QBE system will be more variable.
SQL (Structured Query Language) SQL is a set-based, declarative query language, not an imperative language such as C or BASIC. However, there are extensions to Standard SQL which add procedural programming language functionality, such as control-of-flow constructs

What is the difference between Script and Query?
Script is a term used to describe programs that aren't compiled (that is, turned into 1's and 0's) first. A scripting engine reads the code exactly how you wrote it, and turns it into a computer program on the fly. Query is just a fancy word for question, but on the web it generally means "SQL Query." An SQL query is a way of asking a database for information, that follows the Structured Query Language syntax. All SQLs are a bit off of the actual SQL standard, and you have to work with whatever version your relational database (RD) supports.
