Does CONVERT_CURRENCY work in rev 68

Hi folks,

We are using CONVERT_CURRENCY and it's working nicely on our REV 82 server however the same exact code is not working on REV 68.  Does anybody know if this should still work on 68? 

Sample code taken from SAP help (could not find release)

SELECT CONVERT_CURRENCY(amount=>price,

  "SOURCE_UNIT_COLUMN" =>source_unit,

  "SCHEMA" => 'SYSTEM',

  "TARGET_UNIT_COLUMN" => target_unit,

  "REFERENCE_DATE" =>'2013-09-23',

  "ERROR_HANDLING"=>'set to null',

  "CLIENT" => '000') as converted

  FROM sample_input;

In 68 we get SAP DBTech JDBC: [257] (at 1777): sql syntax error: incorrect syntax near "=>":

Thanks,

-Patrick
