Client APIs and toolsYou can use the HCL OneDB™ implementation of client APIs to develop applications for HCL OneDB™ database servers.
HCL OneDB™ JDBC Driver GuideThe HCL OneDB™ JDBC Driver Programmer's Guide describes how to install, load, and use HCL OneDB™ JDBC Driver to connect to the HCL OneDB™ database from within a Java™ application.
Appendixes
Convert internal HCL OneDB™ data typesFor your Java™ application to work with the internal server representation of HCL OneDB™ data types, use the IfxToJavaType class. For example, if your application is using the HCL® OneDB® Change Data Capture API, you can use the IfxToJavaType class to interpret the byte stream.
The IfxToJavaType classThe IfxToJavaType class handles all the HCL OneDB™ to Java™ data type conversions. Separate methods are provided for converting each HCL OneDB™ data type.
The convertDateToDays() methodThe convertDateToDays() method converts java.sql.Date to an int data type that encodes the number of days since January 1, 1900 as 1. Dates earlier than January 1, 1900 are encoded as negative numbers.
