public java.sql.PreparedStatement prepareStatement(java.lang.String sql, int autoGeneratedKeys) 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, or an SQL statement able to return auto-generated keys (the list of such statements is vendor-specific).
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 SQLExceptions.
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
. The holdability of the created result sets can be determined by calling getHoldability()

Creates a default PreparedStatement
object capable of returning the auto-generated keys designated by the given array. This
array contains the indexes of the columns in the target table that contain the auto-generated keys that should be made available. The driver
will ignore the array if the SQL statement is not an INSERT
statement, or an SQL statement able to return auto-generated keys
(the list of such statements is vendor-specific).
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.
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

public void setClientInfo(java.util.Properties properties) throws java.sql.SQLClientInfoException
Sets the value of the connection's client info properties. The Properties
object contains the
names and values of the client info properties to be set. The set of client info properties contained in the
properties list replaces the current set of client info properties on the connection. If a property that is
currently set on the connection is not present in the properties list, that property is
cleared. Specifying an empty properties list will clear all of the properties on the connection. See
setClientInfo (String, String)
for more information.
If an error occurs in setting any of the client info properties, a SQLClientInfoException
is
thrown. The SQLClientInfoException
contains information indicating which client info properties
were not set. The state of the client information is unknown because some databases do not allow multiple
client info properties to be set atomically. For those databases, one or
more properties may have been set before the error occurred.

public void setClientInfo(java.lang.String name, java.lang.String value) throws java.sql.SQLClientInfoException
Sets the value of the client info property specified by name to the value specified by value.
Applications may use the DatabaseMetaData.getClientInfoProperties
method to determine the client info properties supported by
the driver and the maximum length that may be specified for each property.
The driver stores the value specified in a suitable location in the database. For example in a special register, session parameter, or system table column. For efficiency the driver may defer setting the value in the database until the next time a statement is executed or prepared. Other than storing the client information in the appropriate place in the database, these methods shall not alter the behavior of the connection in anyway. The values supplied to these methods are used for accounting, diagnostics and debugging purposes only.
The driver shall generate a warning if the client info name specified is not recognized by the driver.
If the value specified to this method is greater than the maximum length for the property the driver may either truncate the value and
generate a warning or generate a SQLClientInfoException
. If the driver generates a SQLClientInfoException
, the
value specified was not set on the connection.
The following are standard client info properties. Drivers are not required to support these properties however if the driver supports a client info property that can be described by one of the standard properties, the standard property name should be used.

createArrayOf

implementation-defined whether the Array

Note: The JDBC driver is responsible for mapping the elements Object
array to the default JDBC SQL type defined in
