Class PreparedStatement

java.lang.Object
  extended bycom.mysql.jdbc.Statement
      extended bycom.mysql.jdbc.PreparedStatement
All Implemented Interfaces:
java.sql.PreparedStatement, java.sql.Statement

public class PreparedStatement
extends Statement
implements java.sql.PreparedStatement

A SQL Statement is pre-compiled and stored in a PreparedStatement object. This object can then be used to efficiently execute this statement multiple times.

Note: The setXXX methods for setting IN parameter values must specify types that are compatible with the defined SQL type of the input parameter. For instance, if the IN parameter has SQL type Integer, then setInt should be used.

If arbitrary parameter type conversions are required, then the setObject method should be used with a target SQL type.

                         java.sql.Timestamp x)
                  throws java.sql.SQLException
Set a parameter to a java.sql.Timestamp value. The driver converts this to a SQL TIMESTAMP value when it sends it to the database.

Specified by:
setTimestamp in interface java.sql.PreparedStatement
Parameters:
parameterIndex - the first parameter is 1...
x - the parameter value
Throws:
java.sql.SQLException - if a database access error occurs

setTimestamp

public void setTimestamp(int parameterIndex,
                         java.sql.Timestamp x,
                         java.util.Calendar cal)
                  throws java.sql.SQLException
Set a parameter to a java.sql.Timestamp value. The driver converts this to a SQL TIMESTAMP value when it sends it to the database.

Specified by:
setTimestamp in interface java.sql.PreparedStatement
Parameters:
parameterIndex - the first parameter is 1, the second is 2, ...
x - the parameter value
cal - the calendar specifying the timezone to use
Throws:
java.sql.SQLException - if a database-access error occurs.

setURL

public void setURL(int parameterIndex,
                   java.net.URL arg)
            throws java.sql.SQLException
Specified by:
setURL in interface java.sql.PreparedStatement
Throws:
java.sql.SQLException
See Also:
setURL(int, URL)

setUnicodeStream

public void setUnicodeStream(int parameterIndex,
                             java.io.InputStream x,
                             int length)
                      throws java.sql.SQLException
Deprecated.  

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. JDBC will read the data from the stream as needed, until it reaches end-of-file. The JDBC driver will do any necessary conversion from UNICODE to the database char format.

Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.

Specified by:
setUnicodeStream in interface java.sql.PreparedStatement
Parameters:
parameterIndex - the first parameter is 1...
x - the parameter value
length - the number of bytes to read from the stream
Throws:
java.sql.SQLException - if a database access error occurs

addBatch

public void addBatch()
              throws java.sql.SQLException

Specified by:
addBatch in interface java.sql.PreparedStatement
Throws:
java.sql.SQLException - if a database-access error occurs.
See Also:
Statement.addBatch(java.lang.String)

clearParameters

public void clearParameters()
                     throws java.sql.SQLException
In general, parameter values remain in force for repeated used of a Statement. Setting a parameter value automatically clears its previous value. However, in some cases, it is useful to immediately release the resources used by the current parameter values; this can be done by calling clearParameters

Specified by:
clearParameters in interface java.sql.PreparedStatement
Throws:
java.sql.SQLException - if a database access error occurs

close

public void close()
           throws java.sql.SQLException
Closes this prepared statement and releases all resources.

Specified by:
close in interface java.sql.Statement
Overrides:
close in class Statement
Throws:
java.sql.SQLException - if database error occurs.

execute

public boolean execute()
                throws java.sql.SQLException
Some prepared statements return multiple results; the execute method handles these complex statements as well as the simpler form of statements handled by executeQuery and executeUpdate

Specified by:
execute in interface java.sql.PreparedStatement
Returns:
true if the next result is a ResultSet; false if it is an update count or there are no more results
Throws:
java.sql.SQLException - if a database error occurs.

executeBatch

public int[] executeBatch()
                   throws java.sql.SQLException
JDBC 2.0 Submit a batch of commands to the database for execution. This method is optional.

Specified by:
executeBatch in interface java.sql.Statement
Overrides:
executeBatch in class Statement
Returns:
an array of update counts containing one element for each command in the batch. The array is ordered according to the order in which commands were inserted into the batch
Throws:
java.sql.SQLException - if a database-access error occurs, or the driver does not support batch statements
java.sql.BatchUpdateException - DOCUMENT ME!

executeQuery

public java.sql.ResultSet executeQuery()
                                throws java.sql.SQLException
A Prepared SQL query is executed and its ResultSet is returned

Specified by:
executeQuery in interface java.sql.PreparedStatement
Returns:
a ResultSet that contains the data produced by the query - never null
Throws:
java.sql.SQLException - if a database error occurs.

executeUpdate

public int executeUpdate()
                  throws java.sql.SQLException
Execute a SQL INSERT, UPDATE or DELETE statement. In addition, SQL statements that return nothing such as SQL DDL statements can be executed.

Specified by:
executeUpdate in interface java.sql.PreparedStatement
Returns:
either the row count for INSERT, UPDATE or DELETE; or 0 for SQL statements that return nothing.
Throws:
java.sql.SQLException - if a database access error occurs

toString

public java.lang.String toString()
Returns this PreparedStatement represented as a string.

Returns:
this PreparedStatement represented as a string.
Throws:
java.lang.RuntimeException - if an error occurs

setBytesNoEscape

                         throws java.sql.SQLException
Used by updatable result sets for refreshRow() because the parameter has already been escaped for updater or inserter prepared statements.

Parameters:
parameterIndex - the parameter to set.
