JDBC Type 4 Driver 1.1 Programmer's Reference

java.sql.DatabaseMetaData.getTables(String catalog, String schemaPattern,
String[] types)
The column is added to the column data, but its value is
set to NULL because SQL/MX does not support the
column type for types as follows:
TYPE_CAT,
TYPE_SCHEMA,
TYPE_NAME,
SELF_REFERENCING_COL_NAME,
and REF_GENERATION.
java.sql.DatabaseMetaData.getUDTs(String catalog, String schemaPattern, String
tableNamePattern, int[] types)
BASE_TYPE is added to the column data, but its value is
set to NULL because SQL/MX does not support the base
type.
java.sql.DatabaseMetaData.getVersionColumns()
Mimics the
DatabaseMetaData.getBestRowIdentifier()
method because SQL/MX does not support
SQL_ROWVER (a columns function that returns the
column or columns in the specified table, if any, that are
automatically updated by the data source when any value
in the row is updated by any transaction).
java.sql.Connection.createStatement(...)java.sql.Connection.prepareStatement(...)
The Type 4 driver does not support the scroll-sensitive
result set type, so an SQLWarning is issued if an
application requests that type. The result set is changed to
a scroll-insensitive type.
java.sql.Connection.setReadOnly(...)
The read-only attribute is ignored.
java.sql.ResultSet.setFetchDirection(...)
The fetch direction attribute is ignored.
java.sql.Statement.setEscapeProcessing(...)
Because SQL/MX parses the escape syntax, disabling
escape processing has no effect.
java.sql.Statement.setFetchDirection(...)
The fetch direction attribute is ignored.
HP Extensions
Internationalization of Messages
The following HP extensions to the JDBC standard are implemented in the Type 4 driver.
Internationalization of Messages
The Type 4 driver is designed so that Java messages can be adopted for various languages. The error messages are stored outside the source code in a separate property file and
retrieved dynamically based on the locale setting. The error messages in different languages are stored in separate property files based on the language and country. This extension
does not apply to all messages that can occur when running JDBC applications.
