Juan Ignacio Saitua created MADLIB-1377:
-------------------------------------------
Summary: Pivot documentation is wrong about some optional
parameters
Key: MADLIB-1377
URL: https://issues.apache.org/jira/browse/MADLIB-1377
Project: Apache MADlib
Issue Type: Bug
Components: Documentation
Reporter: Juan Ignacio Saitua
Fix For: v1.16
I tried to output an array column instead of multiple columns using the
optional parameter _output_type_, but it throws an error:
{code:sql}
--This is based on the example from the documentation page
--This works ok
SELECT madlib.pivot(source_table := 'pivset', out_table := 'pivout', index :=
'id', pivot_cols := 'piv', pivot_values := 'val');
pivot
-------
(1 row)
--Adding the optional parameter, output_type, doesn't work:
SELECT madlib.pivot(source_table := 'pivset', out_table := 'pivout', index :=
'id', pivot_cols := 'piv', pivot_values := 'val', output_type := 'array');
ERROR: function madlib.pivot(source_table => unknown, out_table => unknown,
index => unknown, pivot_cols => unknown, pivot_values => unknown, output_type
=> unknown) does not exist
{code}
Looking at the corresponding _madlib.pivot()_ function, there's no parameter
defined as _default_, so it seems that you can't have optional parameters as
stated on the documentation?
