------------------------------------
Summary: Document Oracle-specific functions, such as NVL and
LTRIM, in the SQL reference
Key: CALCITE-2846
URL: https://issues.apache.org/jira/browse/CALCITE-2846
Project: Calcite
Issue Type: Bug
Reporter: Julian Hyde
Assignee: Julian Hyde
Document Oracle-specific functions (DECODE, NVL, LTRIM, RTRIM, SUBSTR,
GREATEST, LEAST) in the [SQL
reference|https://calcite.apache.org/docs/reference.html].
Same goes for MySQL-specific functions (e.g. JSON_TYPE).
I don't think we should have separate lists of Oracle-specific functions and
MySQL-specific functions. Because quite a few functions appear in more than one
place. Better, I think, to have a concise annotation against each function
which tables it occurs in.
The current list of tables is standard, oracle, spatial, mysql. Perhaps also
indicate whether a function is an extension to the SQL standard but still
occurs in Calcite's default table.
