ANSI Compliance and SQL/MX Extensions
NonStop SQL/MX complies most closely with Entry Level SQL as described in ANSI
X3.135-1992 and ISO/IEC 9075:1992. NonStop SQL/MX also includes some features
from Intermediate and Full Level ANSI/ISO SQL in addition to special SQL/MX
extensions to the SQL language.
Statements and SQL elements in this manual are ANSI compliant unless specified as
SQL/MX extensions. For details about NonStop SQL/MX's conformance with
SQL:1999 standards, see Appendix E, Standard SQL and SQL/MX.
