Description: Non-Standard SQL refers to SQL dialects that deviate from the ANSI SQL standard, which is a set of rules defining how queries should be structured and executed in relational databases. These dialects are specific to certain database management systems (DBMS) and may include features, functions, and syntax not present in the standard. For example, various database systems have their own extensions and variations that allow developers to leverage unique features of each platform. This can include specific functions for query optimization, transaction handling, or additional data types. The relevance of Non-Standard SQL lies in its ability to provide more efficient and tailored solutions to the particular needs of applications, although this can lead to portability issues between different DBMS. In an environment where efficiency and customization are crucial, the use of Non-Standard SQL can be a powerful tool for optimizing query performance and improving data management.
