to_char_number::=
to_char_number
TO_CHAR
converts n
of NUMBER
datatype to a value of VARCHAR2
datatype, using the optional number format fmt
. If you omit fmt
, n
is converted to a VARCHAR2
value exactly long enough to hold its significant digits.
The nlsparam
specifies these characters that are returned by number format elements:
This argument can have this form:
'NLS_NUMERIC_CHARACTERS = ''dg'' NLS_CURRENCY = ''text'' NLS_ISO_CURRENCY = territory '
The characters d
and g
represent the decimal character and group separator, respectively. They must be different single-byte characters. Note that within the quoted string, you must use two single quotation marks around the parameter values. Ten characters are available for the currency symbol.
If you omit nlsparam
or any one of the parameters, this function uses the default parameter values for your session.
In this example, the output is blank padded to the left of the currency symbol.
