Class AbstractCallableStatement

Implemented Interfaces:
CallableStatement, FirebirdCallableStatement, FirebirdPreparedStatement, FirebirdStatement, PreparedStatement, Statement, Synchronizable

public abstract class AbstractCallableStatement
extends AbstractPreparedStatement
implements CallableStatement, FirebirdCallableStatement

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." Note: Escape syntax currently is not supported. Please use native Firebird procedure call syntax:

 EXECUTE PROCEDURE (param1, ...);

            throws SQLException

Method Details

addBatch

public void addBatch()
            throws SQLException
Adds a set of parameters to this PreparedStatement object's batch of commands.
Overrides:
addBatch in interface AbstractPreparedStatement
Since:
1.2
See Also:
Statement.addBatch, What Is in the JDBC 2.0 API

assertHasData

protected void assertHasData(ResultSet rs)
            throws SQLException
Asserts if the current statement has data to return. It checks if the result set has a row with data.
Parameters:
rs - result set to test

clearBatch

public void clearBatch()
            throws SQLException
Makes the set of commands in the current batch empty. This method is optional.
Overrides:
clearBatch in interface AbstractPreparedStatement
Since:
1.2

execute

public boolean execute()
            throws SQLException
Executes an execute stored procedure. Some prepared statements return multiple results; the execute method handles these complex statements as well as the simpler form of statements handled by the methods executeQuery and executeUpdate.
Overrides:
execute in interface AbstractPreparedStatement
See Also:
Statement.execute

executeBatch

public int[] executeBatch()
            throws SQLException
Submits a batch of commands to the database for execution and if all commands execute successfully, returns an array of update counts. The int elements of the array that is returned are ordered to correspond to the commands in the batch, which are ordered according to the order in which they were added to the batch. The elements in the array returned by the method executeBatch may be one of the following:
  1. A number greater than or equal to zero -- indicates that the command was processed successfully and is an update count giving the number of rows in the database that were affected by the command's execution
  2. A value of -2-- indicates that the command was processed successfully but that the number of rows affected is unknown

    If one of the commands in a batch update fails to execute properly, this method throws a BatchUpdateException, and a JDBC driver may or may not continue to process the remaining commands in the batch. However, the driver's behavior must be consistent with a particular DBMS, either always continuing to process commands or never continuing to process commands. If the driver continues processing after a failure, the array returned by the method BatchUpdateException.getUpdateCounts will contain as many elements as there are commands in the batch, and at least one of the elements will be the following:

  3. A value of -3-- indicates that the command failed to execute successfully and occurs only if a driver continues to process commands after a command fails

A driver is not required to implement this method. The possible implementations and return values have been modified in the Java 2 SDK, Standard Edition, version 1.3 to accommodate the option of continuing to proccess commands in a batch update after a BatchUpdateException obejct has been thrown.

Overrides:
executeBatch in interface AbstractPreparedStatement
Returns:
an array of update counts containing one element for each command in the batch. The elements of the array are ordered according to the order in which commands were added to the batch.
Since:
1.3

executeQuery

public ResultSet executeQuery()
            throws SQLException

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.

setNull

public void setNull(int parameterIndex,
                    int sqlType,
                    String typeName)
            throws SQLException
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.

Overrides:
setNull in interface AbstractPreparedStatement
Parameters:
parameterIndex - the first parameter is 1, the second is 2, ...
sqlType - a value from java.sql.Types
typeName - the fully-qualified name of an SQL user-defined type; ignored if the parameter is not a user-defined type or REF

                      int targetSqlType)
            throws SQLException
Sets the value of the designated parameter with the given object. This method is like the method setObject above, except that it assumes a scale of zero.
Overrides:
setObject in interface AbstractPreparedStatement
Parameters:
parameterIndex - the first parameter is 1, the second is 2, ...
x - the object containing the input parameter value
targetSqlType - the SQL type (as defined in java.sql.Types) to be sent to the database

setObject

public void setObject(int parameterIndex,
                      Object x,
                      int targetSqlType,
                      int scale)
            throws SQLException
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.

Overrides:
setObject in interface AbstractPreparedStatement
Parameters:
parameterIndex - the first parameter is 1, the second is 2, ...
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. For all other types, this value will be ignored.

            throws SQLException

Deprecated. I really have no idea if there is anything else we should be doing here

Sets the designated parameter to the given input stream, which will have the specified number of bytes. When a very large UNICODE value is input to a LONGVARCHAR parameter, it may be more practical to send it via a java.io.InputStream object. The data will be read from the stream as needed until end-of-file is reached. The JDBC driver will do any necessary conversion from UNICODE to the database char format. The byte format of the Unicode stream must be Java UTF-8, as defined in the Java Virtual Machine Specification.
