The value of CURRENT LOCALE LC_CTYPE is replaced by the string constant or host variable specified. The value must be a CHAR or VARCHAR character string that is no longer than 50 bytes.

If a host variable is specified, its value must not be null. If it has an associated indicator, the value of the indicator value must not indicate a null value. The locale must:

  • Be left justified within the host variable
  • Be padded on the right with blanks if its length is less than that of the host variable

The value of CURRENT LOCALE LC_CTYPE is replaced by the value specified. The value must not be longer than 50 bytes and must be a valid locale.
