12700-12799: National Language Support Messages

This section lists messages generated when the National Language Support feature of Oracle is accessed.

ORA-12700: invalid NLS parameter value name

Cause: An invalid NLS initialization parameter was specified.

Action: Check the syntax and spelling of the parameter. Enter the correct parameter into the initialization parameter file.

ORA-12701: CREATE DATABASE character set is not known

Cause: The character set specified in the CREATE DATABASE command does not exist on the system.

Action: Refer to your Oracle operating system-specific documentation for more information about character sets on the system. Use a valid character set in the CREATE DATABASE command.

ORA-12702: invalid NLS parameter string used in SQL function

Cause: An invalid parameter or value was entered in the NLS parameter string in a SQL function.

Action: Check the syntax of the function and the parameters. Enter the command again using the correct syntax and valid values.

ORA-12703: this character set conversion is not supported

Cause: An attempt was made to use the CONVERT function to convert between two character sets, and the requested conversion is not possible due to unavailability of one or both character sets.

Action: Use character sets available on the system in the CONVERT function.

ORA-12704: character set mismatch

Cause: One of the following:

• The string operands(other than an nlsparams argument) to an operator or built-in function do not have the same character set.
• An nlsparams operand is not in the database character set.
• String data with character set other than the database character set is passed to a built-in function not expecting it.
• The second argument to CHR() or CSCONVERT() is not CHAR_CS or NCHAR_CS.
• A string expression in the VALUES clause of an INSERT statement. or the SET clause of an UPDATE statement, does not have the same character set as the column into which the value would be inserted.
• A value provided in a DEFAULT clause when creating a table does not have the same character set as declared for the column.
• An argument to a PL/SQL function does not conform to the character set requirements of the corresponding parameter.

Action: Strings declared with NCHAR or NCHAR VARYING do not interoperate with strings declared with CHAR or VARCHAR2. Use TRANSLATE() function to explicitly convert one to the other.

ORA-12705: invalid or unknown NLS parameter value specified

Cause: There are two possible causes: Either an attempt was made to issue an ALTER SESSION statement with an invalid NLS parameter or value; or the NLS_LANG environment variable contains an invalid language, territory, or character set.

Action: Check the syntax of the ALTER SESSION command and the NLS parameter, correct the syntax and retry the statement, or specify correct values in the NLS_LANG environment variable. For more information about the syntax of the ALTER SESSION command, see the index entry on "ALTER SESSION command" in Oracle8 Server SQL Reference.

ORA-12706: this CREATE DATABASE character set is not allowed

Cause: An attempt was made to create a database on an ASCII-based machine using an EBCDIC-based character set or vice versa. This is not permitted.

Action: Create the database using either ASCII-based or EBCDIC-based character sets, depending on what is supported by the hardware. Refer to your Oracle operating system-specific documentation for more information about the type of character set supported.
