clearWarnings

public void clearWarnings()
                   throws java.sql.SQLException
Clears all warnings reported for this Connection object. After a call to this method, the method getWarnings returns null until a new warning is reported for this Connection object.

Specified by:
clearWarnings in interface java.sql.Connection

close

public void close()
           throws java.sql.SQLException
Releases this Connection object's database and JDBC resources immediately instead of waiting for them to be automatically released.

Calling the method close on a Connection object that is already closed is a no-op.

Note: A Connection object is automatically closed when it is garbage collected. Certain fatal errors also close a Connection object.

Specified by:
close in interface java.sql.Connection

commit

public void commit()
            throws java.sql.SQLException
Makes all changes made since the previous commit/rollback permanent and releases any database locks currently held by this Connection object. This method should be used only when auto-commit mode has been disabled.

Specified by:

getWarnings

public java.sql.SQLWarning getWarnings()
                                throws java.sql.SQLException
Retrieves the first warning reported by calls on this Connection object. If there is more than one warning, subsequent warnings will be chained to the first one and can be retrieved by calling the method SQLWarning.getNextWarning on the warning that was retrieved previously.

This method may not be called on a closed connection; doing so will cause an SQLException to be thrown.

Note: Subsequent warnings will be chained to this SQLWarning.

Specified by:
getWarnings in interface java.sql.Connection

isClosed

public boolean isClosed()
                 throws java.sql.SQLException
Retrieves whether this Connection object has been closed. A connection is closed if the method close has been called on it or if certain fatal errors have occurred. This method is guaranteed to return true only when it is called after the method Connection.close has been called.

This method generally cannot be called to determine whether a connection to a database is valid or invalid. A typical client can determine that a connection is invalid by catching any exceptions that might be thrown when an operation is attempted.

Specified by:
isClosed in interface java.sql.Connection

isReadOnly

public boolean isReadOnly()
                   throws java.sql.SQLException
Retrieves whether this Connection object is in read-only mode.

Specified by:

nativeSQL

public java.lang.String nativeSQL(java.lang.String sql)
                           throws java.sql.SQLException
Converts the given SQL statement into the system's native SQL grammar. A driver may convert the JDBC SQL grammar into its system's native SQL grammar prior to sending it. This method returns the native form of the statement that the driver would have sent.

Specified by:
nativeSQL in interface java.sql.Connection

prepareCall

public java.sql.CallableStatement prepareCall(java.lang.String sql)
                                       throws java.sql.SQLException
Creates a CallableStatement object for calling database stored procedures. The CallableStatement object provides methods for setting up its IN and OUT parameters, and methods for executing the call to a stored procedure.

Note: This method is optimized for handling stored procedure call statements. Some drivers may send the call statement to the database when the method prepareCall is done; others may wait until the CallableStatement object is executed. This has no direct effect on users; however, it does affect which method throws certain SQLExceptions.

Result sets created using the returned CallableStatement object will by default be type TYPE_FORWARD_ONLY and have a concurrency level of CONCUR_READ_ONLY.

Specified by:
prepareCall in interface java.sql.Connection

prepareCall

public java.sql.CallableStatement prepareCall(java.lang.String sql,

prepareStatement

public java.sql.PreparedStatement prepareStatement(java.lang.String sql)
                                            throws java.sql.SQLException
Creates a PreparedStatement object for sending parameterized SQL statements to the database.

A SQL statement with or without IN parameters can be pre-compiled and stored in a PreparedStatement object. This object can then be used to efficiently execute this statement multiple times.

Note: This method is optimized for handling parametric SQL statements that benefit from precompilation. If the driver supports precompilation, the method prepareStatement will send the statement to the database for precompilation. Some drivers may not support precompilation. In this case, the statement may not be sent to the database until the PreparedStatement object is executed. This has no direct effect on users; however, it does affect which methods throw certain SQLException objects.

Result sets created using the returned PreparedStatement object will by default be type TYPE_FORWARD_ONLY and have a concurrency level of CONCUR_READ_ONLY.

Specified by:
prepareStatement in interface java.sql.Connection

                                            throws java.sql.SQLException
Creates a default PreparedStatement object capable of returning the auto-generated keys designated by the given array. This array contains the names of the columns in the target table that contain the auto-generated keys that should be returned. This array is ignored if the SQL statement is not an INSERT statement.

An SQL statement with or without IN parameters can be pre-compiled and stored in a PreparedStatement object. This object can then be used to efficiently execute this statement multiple times.

                                            throws java.sql.SQLException
Creates a default PreparedStatement object that has the capability to retrieve auto-generated keys. The given constant tells the driver whether it should make auto-generated keys available for retrieval. This parameter is ignored if the SQL statement is not an INSERT statement.

Note: This method is optimized for handling parametric SQL statements that benefit from precompilation. If the driver supports precompilation, the method prepareStatement will send the statement to the database for precompilation. Some drivers may not support precompilation.
