SUMMARY: NESTED | FIELD | CONSTR | METHOD | DETAIL: FIELD | CONSTR | METHOD |
The interface used to execute SQL stored procedures. The JDBC API provides a stored procedure SQL escape syntax that allows stored procedures to be called in a standard way for all RDBMSs. This escape syntax has one form that includes a result parameter and one that does not. If used, the result parameter must be registered as an OUT parameter. The other parameters can be used for input, output or both. Parameters are referred to sequentially, by number, with the first parameter being 1.
{?= call <procedure-name>[<arg1>,<arg2>, ...]} {call <procedure-name>[<arg1>,<arg2>, ...]}
IN parameter values are set using the set
methods inherited from
PreparedStatement
. The type of all OUT parameters must be
registered prior to executing the stored procedure; their values
are retrieved after execution via the get
methods provided here.
A CallableStatement
can return one ResultSet
object or
multiple ResultSet
objects. Multiple
ResultSet
objects are handled using operations
inherited from Statement
.
For maximum portability, a call's ResultSet
objects and
update counts should be processed prior to getting the values of output
parameters.

registerOutParameter
should be used for a user-defined or REF
output parameter. Examples
of user-defined types include: STRUCT
, DISTINCT
,
JAVA_OBJECT
, and named array types.
Before executing a stored procedure call, you must explicitly
call registerOutParameter
to register the type from
java.sql.Types
for each
OUT parameter. For a user-defined parameter, the fully-qualified SQL
type name of the parameter should also be given, while a REF
parameter requires that the fully-qualified type name of the
referenced type be given. A JDBC driver that does not need the
type code and type name information may ignore it. To be portable,
however, applications should always provide these values for
user-defined and REF
parameters.
Although it is intended for user-defined and REF
parameters,
this method may be used to register a parameter of any JDBC type.
If the parameter does not have a user-defined or REF
type, the
typeName parameter is ignored.
Note: When reading the value of an out parameter, you must use the getter method whose Java type corresponds to the parameter's registered SQL type.

The given Java object will be converted to the given targetSqlType

If the object has a custom mapping (is of a class implementing the

to write it
to the SQL data stream.
If, on the other hand, the object is of a class implementing

The JDBC specification specifies a standard mapping from
Java Object

will be converted to the corresponding SQL type before being
sent to the database.
Note that this method may be used to pass datatabase-
specific abstract data types, by using a driver-specific Java

If the object is of a class implementing the interface SQLData

If, on the other hand, the object is of a class implementing

This method throws an exception if there is an ambiguity, for example, if the object is of a class implementing more than one of the interfaces named above.

This version of the method setNull
should
be used for user-defined types and REF type parameters. Examples
of user-defined types include: STRUCT, DISTINCT, JAVA_OBJECT, and
named array types.
Note: To be portable, applications must give the SQL type code and the fully-qualified SQL type name when specifying a NULL user-defined or REF parameter. In the case of a user-defined type the name is the type name of the parameter itself. For a REF parameter, the name is the type name of the referenced type. If a JDBC driver does not need the type code or type name information, it may ignore it. Although it is intended for user-defined and Ref parameters, this method may be used to set a null parameter of any JDBC type. If the parameter does not have a user-defined or REF type, the given typeName is ignored.
