(a) Function

Specifies the character set used for character code conversion in the JDBC driver.

(b) Format

 
public void setEncodeLang (String encode_lang)
 

(c) Argument

String encode_lang

Specifies a character set supported by Java (such as MS932).

If OFF is specified with this method or if nothing is specified (including in the ENCODELANG settings of Properties info and the URL), the following operation takes place.

OFF:

The JDBC driver determines the character set that corresponds to the character codes type of the connected HiRDB. The following table shows the correspondence between the connected HiRDB character codes type and the character encoding used by the JDBC driver:

HiRDB character codes type*	Character encoding used
lang-c	8859_1
sjis	Java Virtual Machine standard encoding
ujis	EUCJIS
utf-8	UTF-8
chinese	GB2312

^* The specification value is in the -c option of the pdsetup command for UNIX and the -c option of the pdntenv command for Windows. For the character codes types when the pdntenv command is not executed, see the HiRDB Version 8 Installation and Design Guide.

None:

For UNIX:

The JDBC driver determines the character set that corresponds to the HiRDB character codes type.

For Windows:

The JDBC driver uses the following rules to determine the character set:

Java Virtual Machine standard encoding	HiRDB character codes type
	SJIS	Other than SJIS
MS932	MS932	Character set corresponding to the HiRDB character codes type
Other than MS932	SJIS

(d) Return value

None.

(e) Functional detail

In a Java program, Unicode is used for the character codes. Therefore, during character data processing with HiRDB, the JDBC driver performs mutual character code conversion between the HiRDB character data and Unicodes. For this character code conversion processing, the JDBC driver uses the encoder and decoder provided by the Java Virtual Machine. This method specifies the character set names specified by the JDBC driver for the encoder and decoder that are provided by the Java Virtual Machine.

(f) Exception that occurs

None.
