datname

datname is a placeholder or variable name often used in programming and database contexts. It commonly represents the name of a database. The term "datname" is derived from "database name."

When interacting with database systems, developers and administrators frequently need to specify which database they wish to connect to or operate on. This is where a variable like datname comes into play. It acts as a container for the string that identifies a specific database. For example, in a connection string, you might see a parameter like `database=mydatabase` or `datname=mydatabase`.

The use of datname is not specific to any single programming language or database technology. It is a convention that can be found in SQL scripts, application code written in languages like Python, Java, or PHP, and configuration files for various database management systems, including PostgreSQL, MySQL, and SQL Server. Its purpose is to provide a clear and unambiguous way to reference a database by its unique identifier. This helps ensure that operations are performed on the intended data store, preventing potential errors or data corruption.
