Subject [jira] Commented: (DERBY-1289) Allow the VARCHAR function to convert numeric values
Date Sat, 11 Nov 2006 22:54:38 GMT
    [ http://issues.apache.org/jira/browse/DERBY-1289?page=comments#action_12449045 ] 
            
Christian d'Heureuse commented on DERBY-1289:
---------------------------------------------

A comment in org.apache.derby.impl.sql.compile.BaseTypeCompiler.numberConvertible() reads:

   // Numbers can only be converted to other numbers,
   // and CHAR, (not VARCHARS or LONGVARCHAR).
   // Only with the CHAR() or VARCHAR()function can they be converted.

The last sentence is not correct, because the VARCHAR function currently does not allow numeric
values:
  VALUES VARCHAR(123);
produces:
  Cannot convert types 'INTEGER' to 'VARCHAR'.

> It would be good if the VARCHAR function (http://db.apache.org/derby/docs/dev/ref/rrefbuiltvarchar.html)
could convert integer and floating point values to strings just as the CHAR function (http://db.apache.org/derby/docs/dev/ref/rrefbuiltchar.html)
can do (though without the size limit).
