[jira] [Comment Edited] (CALCITE-2846) Document Oracle-specific
functions, such as NVL and LTRIM, in the SQL reference
[ https://issues.apache.org/jira/browse/CALCITE-2846?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16778546#comment-16778546 ]

---------------------------------------------------------------
This issue and CALCITE-2876 are talking about adding an operator table for MySQL. Should it be a new class, {{MySqlSqlOperatorTable}}? Let's come to consensus before we proceed.

> Key: CALCITE-2846
> URL: https://issues.apache.org/jira/browse/CALCITE-2846
> Project: Calcite
> Issue Type: Improvement
> Components: site
> Reporter: Julian Hyde
> Assignee: Hongze Zhang
> Priority: Major
> Labels: documentation
>
> 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.
