INTERVAL MINUTE(p) TO SECOND
INTERVAL SECOND(p)
Floating-Point Support
The Type 4 driver supports only IEEE floating-point data to be passed between the application
client and the Type 4 driver.
SQLJ Support
The Type 4 driver supports non-customized SQLJ applications, but does not support customized
SQLJ applications.
JDBC 3.0 Features Not Supported by the Type 4 Driver
These features are not required for JDBC 3.0 compliance, and they are not supported by the HP
JDBC Type 4 driver.
• Multiple result sets returned by batch statements.
• Database savepoint support. (Not provided in Neoview SQL )
• Retrieval of auto generated keys.
• Transform group and type mapping.
• Relationship between connector architecture and JDBC 3.0 SPI.
• Secured socket communication or encryption for the interaction between the Type 4 driver
and NDCS.
• Security context (user name and password) implicit propagation from AppServer to the
Type 4 driver.
• IPV6 protocol stack. (IPV6 addressing is emulated over IPV4 on the Neoview
platform—server side)
• Distributed transactions.
Restrictions
• The Type 4 driver supports only database features that are supported by Neoview SQL and
SPJ. Therefore, the Type 4 driver is not fully compliant with JDBC 3.0 specifications.
• The Type 4 driver depends on the HP connectivity service for all server side manageability
related features.
