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.
