Why Isn't ANSI-92 SQL More Widely Adopted Despite Its Advantages?

ANSI-92 SQL: Understanding Its Limited Adoption

While ANSI-92 SQL boasts enhanced readability and usability, its widespread adoption lags behind ANSI-89. This is surprising, given that most relational database management systems (RDBMS) support both standards.

Performance: A False Dichotomy

The common misconception that ANSI-92 offers superior performance is unfounded. RDBMS engines translate all SQL syntax into an internal format before processing, negating any performance advantage of one syntax over the other. Expert consensus confirms this.

Inertia and Habit in Development

The transition from ANSI-89 to ANSI-92 faces significant hurdles. Established codebases relying on ANSI-89 syntax, coupled with developer familiarity and reluctance to change, create resistance to adoption.

A Gradual Shift Towards ANSI-92

Despite the slow uptake, positive trends are emerging. Increased visibility of ANSI-92 in online communities suggests growing acceptance. Furthermore, ongoing SQL standard evolution continues to prioritize readability and maintainability.

Conclusion: A Future for ANSI-92?

The superior readability of ANSI-92 SQL is undeniable, yet its adoption remains hampered by legacy code and a lack of perceived performance gains. However, a gradual shift in developer practices and continued improvements in SQL standards suggest that ANSI-92 will likely achieve greater prominence in the future.
