> Key: TAJO-167
> URL: https://issues.apache.org/jira/browse/TAJO-167
> Project: Tajo
> Issue Type: Improvement
> Components: planner/optimizer
> Reporter: Hyunsik Choi
> Assignee: Hyunsik Choi
> Fix For: 0.2-incubating
>
> Attachments: TAJO-167.patch
>
>
> This patch removes CountValueFunctionExpr and add GeneralSetFunctionExpr
> corresponding to general_set_function of SQL 2003 BNF
> (http://savage.net.au/SQL/sql-2003-2.bnf.html#general set function).
> After this patch, we should use GeneralSetFunctionExpr to represent all SQL
> standard aggregation functions (e.g., max, min, avg, sum, stddev_pop,
> stddev_samp and so on).
> Also, GeneralSetFunctionExpr has an attribute for distinct keyword that set
> functions can have.
