> Creating output row type of a Join does not obey case-sensitivity flags
> -----------------------------------------------------------------------

> Key: CALCITE-528
> URL: https://issues.apache.org/jira/browse/CALCITE-528
> Project: Calcite
> Issue Type: Bug
> Affects Versions: 0.9.1-incubating
> Reporter: Aman Sinha
> Assignee: Julian Hyde
> Fix For: 1.9.0
>
>
> In JoinRelBase.createJoinType() which creates a row type of the output row, a
> HashSet of String is used to keep track of unique field names. The field
> names 'column1' and 'Column1' will both be stored. This creates a problem
> for systems which are treating identifiers as case-insensitive (such as
> Drill) which rely on a Project below a Join to create unique names if the
> join columns are the same name (regardless of case).
> Ideally, the comparison for this should be done based on the criteria
> specified in the Lex settings when instantiating the
> SqlParser.ParserConfigImpl. So, if the parser was created with MYSQL Lex
> settings (see Lex.java), it should be obeyed by the
> JoinRelBase.createJoinType().
