Class CharsetMapping
java.lang.Object
com.mysql.jdbc.CharsetMapping
public class CharsetMapping
- extends java.lang.Object
Mapping between MySQL charset names and Java charset names. I've investigated
placing these in a .properties file, but unfortunately under most appservers
this complicates configuration because the security policy needs to be
changed by the user to allow the driver to read them :(

INDEX_TO_CHARSET
public static final java.lang.String[] INDEX_TO_CHARSET
- Map of MySQL-4.1 charset indexes to Java encoding names
INDEX_TO_COLLATION
public static final java.lang.String[] INDEX_TO_COLLATION
- Map of MySQL-4.1 collation index to collation names

getJavaEncodingForMysqlEncoding
public static final java.lang.String getJavaEncodingForMysqlEncoding(java.lang.String mysqlEncoding,
Connection conn)
throws java.sql.SQLException
- Throws:
java.sql.SQLException
getMysqlEncodingForJavaEncoding
public static final java.lang.String getMysqlEncodingForJavaEncoding(java.lang.String javaEncodingUC,
Connection conn)
throws java.sql.SQLException
- Throws:
java.sql.SQLException
getNumberOfCharsetsConfigured
static final int getNumberOfCharsetsConfigured()
getCharacterEncodingForErrorMessages
static final java.lang.String getCharacterEncodingForErrorMessages(ConnectionImpl conn)
throws java.sql.SQLException
- Returns the character encoding for error messages returned from the
server. Doesn't return useful values other than Cp1252 until the driver
has gone through initialization phase and determined server configuration,
as not enough information is available to make an intelligent decision
until then.
- Parameters:
conn
- the connection to the MySQL server
- Returns:
- the Java encoding name that error messages use
- Throws:
java.sql.SQLException
- if determination of the character encoding fails

isMultibyteCharset
static final boolean isMultibyteCharset(java.lang.String javaEncodingName)
getCharsetIndexForMysqlEncodingName
