Data type mapping for ResultSet.getXXX() methods
Use the ResultSet.getXXX() methods to transfer data from the HCL
OneDB™ database to a Java™ program that uses the JDBC API to connect to the HCL
OneDB database. For example, use the
ResultSet.getString() method to get the data stored in a column of data type
LVARCHAR.
Important: If you use an expression within an SQL statement—for example,
SELECT mytype::LVARCHAR FROM mytab—you might not be able to use
ResultSet.getXXX(columnName) to retrieve the value. Use
ResultSet.getXXX(columnIndex) to retrieve the value instead.The getXXX() methods return a null value if the retrieved column value is an SQL null value.
The tables in this section list the ResultSet.getXXX() methods that HCL OneDB JDBC Driver supports for nonextended data types and HCL OneDB extended data types.
