Footnotes

1. Trims trailing spaces from CHARACTER values before counting
2. There is no built-in function by this name, although the number of octets in a string can be determined by using LENGTH(CAST(X AS BLOB)).
3. There are LTRIM and RTRIM functions for equivalent functionality.
4. There is INSTR.
5. There is the CHARINDEX function for equivalent functionality.
6. There is the charindex function for equivalent functionality.
7. Lacks support for [IS [NOT] TRUE|FALSE|UNKNOWN]
8. Without DISTINCT keyword
9. Use MINUS instead of EXCEPT DISTINCT
10. Except compound queries.
11. Only WITHOUT ROWID tables have real primary keys other than the rowid (INTEGER PRIMARY KEY)
12. Only for WITHOUT ROWID tables.
13. SET [CURRENT] ISOLATION used instead of SET TRANSACTION
14. Supports embedded language features but not the specific MODULE syntax
15. "MySQL :: MySQL 5.7 Reference Manual :: 24 INFORMATION_SCHEMA Tables".
16. Included in SYSIBM schema
17. Also includes MySQL-specific extension columns
18. You can use PRAGMA for obtaining this information, and can create an information schema based on this, but it is not build in.
19. Oracle supports the following subfeature in PL/SQL but not in Oracle SQL.
20. Use the ALL PROCEDURES metadata view.
21. Use the ALL_ARGUMENTS and ALL_METHOD_PARAMS metadata views.
