---------------------------------------------
Summary: SQL Function page should specify return types in terms of
SQL types
Key: DRILL-2645
URL: https://issues.apache.org/jira/browse/DRILL-2645
Project: Apache Drill
Issue Type: Bug
Reporter: Daniel Barclay (Drill)
On the SQL Functions page currently at
http://drill.apache.org/docs/sql-functions/, the return type for string
functions is specified in terms of "int", "text", and "byte array" instead of
being specified in terms of Drill SQL types (e.g., "INTEGER", "BYTE ARRAY",
etc.)
Additionally, names of SQL types should be given in all uppercase, as they are
used in the SQL standard, as they are specified to appear in
INFORMATION_SCHEMA.COLUMNS, and as they appear in the JDBC equivalent of
INFORMATION_SCHEMA.COLUMNS. (Another reason is that it's not clear, for
example, which occurrence of "numeric" is the adjective "numeric" and which
means the proper noun (datatype name) "NUMERIC".)
