Supported SQL and PL/SQL Datatypes

The tables in this section list SQL and PL/SQL datatypes, and whether the Oracle JDBC drivers and SQLJ support them. Table 8-2 describes Oracle JDBC driver and SQLJ support for SQL datatypes.

Table 8-4 describes Oracle JDBC driver and SQLJ support for PL/SQL datatypes. Note that PL/SQL datatypes include these categories:

• scalar types

• scalar character types (includes boolean and date datatypes)

• composite types

• reference types

• LOB types
