Frank McQuillan updated MADLIB-1186:
------------------------------------
Priority: Minor (was: Major)
> Correlation query fails with international chars in column name
> ---------------------------------------------------------------

> Key: MADLIB-1186
> URL: https://issues.apache.org/jira/browse/MADLIB-1186

> Issue Type: Bug
> Components: Module: Inferential Statistics

> Priority: Minor
> Fix For: v1.13

>
> We tried running the correlation module in MADlib, on a table that had
> international characters for schema, and column name of one of the
> independent variables. It resulted in the following error:
> {code}
> select
> madlib.correlation(
> '"nåmespace"."dt_gOlf"',
> '"__madlib_temp_26728701_1513000192_9340672___πøA"',
> 'id, temperature, "Humidity"');
> psql:/tmp/build/60928da1/madlib_testsuite/tests/Correlation/sql_CorrelationInternationalCharOutputTestCase/test_correlation_international_char.sql:12:
> ERROR: spiexceptions.SyntaxError: syntax error at or near ""Humidity""
