FROM CLAUSE Meaning and
Definition
-
The "from clause" refers to a crucial component in SQL (Structured Query Language) queries, particularly in SELECT statements. It is a clause that specifies the table or tables from which the data is to be retrieved.
A "from clause" is typically used in conjunction with the SELECT statement to retrieve data from one or more tables in a database. It indicates the source or sources of the data that needs to be fetched. The "from clause" usually follows the SELECT clause and precedes other optional clauses like WHERE, GROUP BY, HAVING, and ORDER BY.
In more detail, the "from clause" establishes the table or tables from which the data will be selected. It can involve a single table or multiple tables, separated by commas. Each table mentioned in the "from clause" represents a specific entity in the database and provides the data to be retrieved.
The "from clause" is an essential component as it enables the combination and linkage of various tables, allowing users to gather data from related sources and perform complex queries. It forms the foundation for handling relational databases, enabling users to access and manipulate data effectively.
Structured and error-free utilization of the "from clause" in SQL queries helps users retrieve accurate and relevant data, and it offers flexibility in querying databases for various solutions or analyses.

Etymology of FROM CLAUSE
The word "from clause" is derived from the combination of two words: "from" and "clause".
The word "from" originated from the Old English word "fram" and can be traced back to the Proto-Germanic word "frumaz". It had various meanings related to movement or position, indicating the starting point or origin of something. Over time, it evolved to be used as a preposition indicating a point of origin or source.
The word "clause" has its roots in the Latin word "clausula" which referred to a small division or section. In grammar, a clause is a group of words that contains a subject and verb and functions as a single unit within a sentence.
When combined, the term "from clause" refers to a specific part of a sentence or query in computer programming or database management systems. It typically represents the source or origin of data that is being retrieved or selected.
