Incorrect example for SYSCS_DIAG.CONTAINED_ROLES in the reference manual
------------------------------------------------------------------------
Key: DERBY-4190
URL: https://issues.apache.org/jira/browse/DERBY-4190
Project: Derby
Issue Type: Bug
Components: Documentation
Affects Versions: 10.5.1.1
Reporter: Knut Anders Hatlen
Priority: Minor
The example for SYSCS_DIAG.CONTAINED_ROLES in the reference manual does not
work.
http://db.apache.org/derby/docs/dev/ref/rrefsyscsdiagtables.html
The example looks like this:
SELECT * FROM TABLE (SYSCS_DIAG.CONTAINED_ROLES(reader))
There are two problems:
1) the table needs an alias (for instance, append AS T1), otherwise this error
is raised:
ERROR 42X01: Syntax error: Encountered "<EOF>" at line 1, column 56.
Issue the 'help' command for general information on IJ command syntax.
Any unrecognized commands are treated as potential SQL commands and executed
directly.
Consult your DBMS server reference documentation for details of the SQL syntax
supported by your server.
2) the name of the role should be a string (needs single quotes), not an
identifier, otherwise this error is raised:
ERROR 42X04: Column 'READER' is either not in any table in the FROM list or
appears within a join specification and is outside the scope of the join
specification or appears in a HAVING clause and is not in the GROUP BY list. If
this is a CREATE or ALTER TABLE statement then 'READER' is not a column in the
target table.
