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

Query languages are computer languages used to make queries into databases and information systems. Broadly, query languages can be classified according to whether they are database query languages or information retrieval query languages. Examples include: * .QL is a proprietary object-oriented query language for querying relational databases; * Common Query Language (CQL) a formal language for representing queries to information retrieval systems such as as web indexes or bibliographic catalogues. * CODASYL; * D is a query language for truly relational database management systems (TRDBMS); * DMX is a query language for Data Mining models; * Datalog is a query language for deductive databases;

Query-based information extraction involves extracting specific information from a text based on a predefined query. This can be done using techniques such as named entity recognition, part-of-speech tagging, and syntactic parsing to identify relevant information based on the query parameters. Natural language processing or machine learning algorithms can be used to match the query with the text and extract the required information.

A query language is a language in which a user requests information from the database. These languages are usually on a level higher than that of a standard
programming language. Query languages can be categorized as either procedural or non procedural.
In a procedural language, the user instructs the system to
perform a sequence of operations on the database to compute the desired result.
In a non procedural language, the user describes the desired information without
giving a specific procedure for obtaining that information.

A procedural language is nothing but what we call relational algebra. Procedural language is just like SQL but with different syntax. In Procedural language for "Select" we use projection and for "where" clause we use selection.

OQL is a database query language(related to ODMG) that is based on SQL and
supports the adding, retrieving, querying, and invocation of
objects. OQL is a version of the Structured Query Language. A object query language that supports complex data types such as multimedia, spatial, compound documents, etc., that are stored as objects. Standard SQL queries can still be used, and the OQL server process converts the objects into relational views. Sanjay

A database "query" is basically a "question" that you ask the database. The results of the query is the information that is returned by the database management system. Queries are usually constructed using SQL (structured query language) which resembles a high-level programming language.
