PostgreSQL using to_char with floor

Ok I am converting from SQL Server to PostgreSQL. I am having trouble with some to_char. 

CASE LENGTH(LTRIM(RTRIM(to_char(floor(_FloatValue)))))
    WHEN 1 THEN '0' || LENGTH(LTRIM(RTRIM(TO_CHAR(floor(_FloatValue))))) || ':'
    ELSE LENGTH(LTRIM(RTRIM(TO_CHAR(FLOOR(_FloatValue))))) || ':'

I'm getting this error

   [2015-11-10 15:40:20] [42883] ERROR: function to_char(double precision) does not exist
   Hint: No function matches the given name and argument types. You might need to add explicit type casts.
   Where: PL/pgSQL function formatfloattohoursminutes(double precision) line 10 at RETURN

Any help would be great.

Solution

  • It looks like you want to left pad with zeros:

    select to_char(_FloatValue, '09.99');
