Re: [SQL] Howto convert floats to text?

Use this PL/pgSQL script to create text(float), varchar(float), char(float):

create function "varchar"(float) returns varchar as
'begin
return $1;
end;
' language 'plpgsql';

create function bpchar(float) returns bpchar as
'begin
return $1;
end;
' language 'plpgsql';

create function text(float) returns text as
'begin
return $1;
end;
' language 'plpgsql';

create function float_text(float) returns text as
'
select text($1);
' language 'sql';
