These two types have fixed precision and cannot represent exactly all real numbers. If you are using another driver or if you want to create driver-independent code, then you must define SQL types that correspond to the index-by table types, as well as defining conversion functions that map between the two.This section discusses the mechanism that JPublisher uses for supporting PL/SQL types in Java code, through PL/SQL conversion functions that convert between each PL/SQL type and a corresponding SQL type to allow access by JDBC.In general, Java programs do not support the binding of PL/SQL-specific types. If the SQL type is an object type, then the corresponding Java type would be an object wrapper class that implements the oracle.sql.ORAData or java.sql.SQLData interface.

JPublisher also supports PL/SQL nested tables and VARRAYs in the same fashion. The JavaScript Number type is a double-precision 64-bit binary format IEEE 754 value, like double in Java or C#. For example −String literals in Java are specified like they are in most other languages by enclosing a sequence of characters between a pair of double quotes.


Primitive types are the data types defined by the language itself.
The difference between a built-in array and an ArrayList in Java, is that the size of an array cannot be modified (if you want to add or remove elements to/from an array, you have to create a new one).

The double is a double precision type which store numbers in 64 bits.

This setting is useful for generating a An intermediate wrapper layer is required to map a If you use the JDBC OCI driver and require only the publishing of scalar index-by tables, then you can use the direct mapping between Java and these types.The following sections demonstrate JPublisher support for PL/SQL The following PL/SQL package is used to illustrate JPublisher support for PL/SQL Use this type map entry whenever you publish a package or type that refers to the To support an index-by table type, a SQL collection type must be defined that permits conversion to and from the PL/SQL index-by table type. These variables are declared to be of a specific type that cannot be changed. The methods return true if the argument is not null and is an object of the same type and with the same numeric value. An index-by table with numeric elements can be mapped to the following Java array types:An index-by table with character elements can be mapped to the following Java array types:In the following circumstances, you must convey certain information for an index-by table type, as described:For index-by tables with character elements, you can optionally specify the maximum size of an individual element, in bytes.

Determines whether this number object is equal to the argument.

For example, assume you have a user-defined SQL object type, To use custom mappings, it is recommended that you clear the default type map, as follows:The predefined default type map defines a correspondence between the To map a given SQL or PL/SQL type to Java, JPublisher uses the following logical progression:Checks the type maps to see if the mapping is already specified.Checks the predefined Java mappings for SQL and PL/SQL types.Checks whether the data type to be mapped is a PL/SQL If none of steps 1 through 3 apply, then the data type must be a user-defined type.

JPublisher generates an JPublisher supports the following TIMESTAMP types as object attributes:If a PL/SQL stored procedure or function or a SQL query returns a The dependency of having the class in the classpath in order to generate the mapping is specified by a If required, you need to perform the following actions to ensure that JPublisher can find the classes:Use Java Development Kit (JDK) 1.4, for mapping to There is currently no JPublisher option to explicitly enable or disable mapping to Run JPublisher with the following options to use your custom mappings:There are three scenarios if JPublisher encounters a PL/SQL stored procedure or function, including method of a SQL object type, which uses a PL/SQL type that is unsupported by JDBC:If you specify a mapping for the PL/SQL type in the default type map or user type map, then JPublisher uses that mapping.If there is no mapping in the type maps, and the PL/SQL type is a If neither of the first two scenarios applies, then JPublisher issues a warning message and uses The following sections discuss further details of JPublisher type mapping features for PL/SQL types unsupported by JDBC:This section describes JPublisher type mapping support for SQL The Oracle JDBC and SQLJ implementations support SQL For Java-to-Java type transformations, which is often necessary for Web services, the In the generated code, the simple index-by table types, The limitation of mapping PL/SQL index-by table to an array is that the table must be indexed by integer.

It ranges from 1 to 38. Java ArrayList. Floating point numbers with an F/f suffix are of type float, double numbers have D/d suffix. The Oracle mapping is the most efficient mapping.

In fact, this is done in the JPublisher default type map to support SQL Be aware that under some circumstances, PL/SQL wrapThis option determines the name of the PL/SQL package into which JPublisher generates the PL/SQL conversion functions: a function to convert each unsupported PL/SQL type to the corresponding SQL type and a function to convert from each corresponding SQL type back to the PL/SQL type. The scale is the number of digits to the right of the decimal point in a number. Default value is 0.0f. double. If a PL/SQL package contains both tables indexed by integer and by Mapping of the index-by table elements follows the JDBC type mappings. The wrapper function that is generated by JPublisher uses the corresponding SQL types for input or output.With this command, JPublisher creates the following:In this example, assume that the conversion function By contrast, if you run JPublisher with the setting In the generated Java code, the JDBC statement calling the wrapper function is:The preceding sections describe the mechanisms that JPublisher employs to access PL/SQL types unsupported by JDBC. They are represented directly in the code without any computation.Literals can be assigned to any primitive type variable. Note that there is already an entry for PL/SQL Although this manual describes conversions as mapping between SQL and PL/SQL types, there is no intrinsic restriction to PL/SQL in this approach. The ArrayList class is a resizable array, which can be found in the java.util package..

Where applicable, they also specify conversion functions to convert between PL/SQL types and SQL types.JPublisher checks the default type map first.
