Understanding formatting date in sql server

Formatting a date in SQL Server involves converting the database's DATETIME, DATE, or TIMESTAMP fields into human-readable forms or specific string layouts. This matters for user-facing applications, compliance reports, internationalization, and even for maintaining consistency between different systems.

Common formatting date in sql server Issues

• Default display: SQL Server shows dates in the system default format, which might not be suitable for your audience.

• Complex syntax: Formatting requires remembering style codes or different functions.

• Regional differences: Formatting for international audiences requires explicit format control.
