Database updating

The Structured Query Language (SQL) is the standard user and application program interface for a relational database.

You may wish to update records in one table based on values in another table.

A database is a collection of information that is organized so that it can be easily accessed, managed and updated.

Computer databases typically contain aggregations of data records or files, containing information about sales transactions or interactions with specific customers.

As a result, start dates look like 1985-03-12 and salaries do not have dollar signs or commas.

The user can replace the information in any field using any valid input format for the data.
