Class CallableStatementWrapper

public final class CallableStatementWrapper extends PreparedStatementWrapper implements CallableStatement

The interface used to execute SQL stored procedures. JDBC 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 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.

Methods that are new in the JDBC 2.0 API are marked "Since 1.2."

Parameters: parameterIndex the first parameter is 1, the second is 2, and so on sqlType the JDBC type code defined by java.sql.Types . If the parameter is of JDBC type NUMERIC or DECIMAL , the version of registerOutParameter that accepts a scale value should be used.

Throws: SQLException if a database access error occurs

registerOutParameter

public final void registerOutParameter(int parameterIndex, int sqlType, int scale)
Registers the parameter in ordinal position parameterIndex to be of JDBC type sqlType. This method must be called before a stored procedure is executed.

The JDBC type specified by sqlType for an OUT parameter determines the Java type that must be used in the get method to read the value of that parameter.

This version of registerOutParameter should be used when the parameter is of JDBC type NUMERIC or DECIMAL .

Parameters: parameterIndex the first parameter is 1, the second is 2, and so on sqlType SQL type code defined by java.sql.Types. scale the desired number of digits to the right of the decimal point. It must be greater than or equal to zero.

Throws: SQLException if a database access error occurs

registerOutParameter

public final void registerOutParameter(int paramIndex, int sqlType, String typeName)
Registers the designated output parameter. This version of the method registerOutParameter should be used for a user-named or REF output parameter. Examples of user-named 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-named 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-named and REF parameters. Although it is intended for user-named and REF parameters, this method may be used to register a parameter of any JDBC type. If the parameter does not have a user-named or REF type, the typeName parameter is ignored.

Note: When reading the value of an out parameter, you must use the getXXX method whose Java type XXX corresponds to the parameter's registered SQL type.

Parameters: paramIndex the first parameter is 1, the second is 2,... sqlType a value from java.sql.Types typeName the fully-qualified name of an SQL structured type

Throws: SQLException if a database access error occurs

Throws: SQLException if a database access error occurs

Since: 1.4

setNull

public void setNull(String parameterName, int sqlType, String typeName)
Sets the designated parameter to SQL NULL. 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.

Sets the value of the designated parameter with the given object. The second argument must be an object type; for integral values, the java.lang equivalent objects should be used.

The given Java object will be converted to the given targetSqlType before being sent to the database. If the object has a custom mapping (is of a class implementing the interface SQLData), the JDBC driver should call the method SQLData.writeSQL to write it to the SQL data stream. If, on the other hand, the object is of a class implementing Ref, Blob, Clob, Struct, or Array, the driver should pass it to the database as a value of the corresponding SQL type.

Note that this method may be used to pass datatabase- specific abstract data types.

Parameters: parameterName the name of the parameter x the object containing the input parameter value targetSqlType the SQL type (as defined in java.sql.Types) to be sent to the database. The scale argument may further qualify this type. scale for java.sql.Types.DECIMAL or java.sql.Types.NUMERIC types, this is the number of digits after the decimal point.

Throws: SQLException if a database access error occurs

Since: 1.4

setObject

public void setObject(String parameterName, Object x)
Sets the value of the designated parameter with the given object. The second parameter must be of type Object; therefore, the java.lang equivalent objects should be used for built-in types.

The JDBC specification specifies a standard mapping from Java Object types to SQL types. The given argument 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 type. If the object is of a class implementing the interface SQLData, the JDBC driver should call the method SQLData.writeSQL to write it to the SQL data stream. If, on the other hand, the object is of a class implementing Ref, Blob, Clob, Struct, or Array, the driver should pass it to the database as a value of the corresponding SQL type.

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.
