Welcome to the SQL section of the Polypheny documentation! This section aims to provide comprehensive information about employing SQL, the powerful query language, within the Polypheny platform.
What is SQL?
Structured Query Language (SQL) is a standard programming language that’s used to manage and manipulate relational databases. SQL offers a robust set of features that allow you to interact with your data in flexible and powerful ways. The language is table-oriented, meaning that it operates on data organized into tables.
Data is represented as sets of tables that include rows and columns. This representation is ideal for handling structured data efficiently.
Here’s an example of a simple SQL query:
SELECT * FROM Users WHERE name = 'John Doe';
In SQL, SELECT
, FROM
, and WHERE
are keywords used to specify the operation. Users
is the table you’re querying, and 'John Doe'
is the criteria for the query.
When to Use SQL
SQL’s capabilities allow for complex structured queries, data manipulation, creation and modification of schema, data distribution, and management of data security.
In the context of Polypheny, SQL is one of the supported query languages and can be used interchangeably with others, depending on your use case. Whether you’re dealing with large amounts of structured data, require robust querying capabilities, or need to manage and manipulate databases efficiently, SQL is a valuable tool within the Polypheny ecosystem.
