      • prepareStatement

        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().

        Specified by:
        prepareStatement in interface java.sql.Connection
        Parameters:
        sql - an SQL statement that may contain one or more '?' IN parameter placeholders
        autoGeneratedKeys - a flag indicating whether auto-generated keys should be returned; one of Statement.RETURN_GENERATED_KEYS or Statement.NO_GENERATED_KEYS
        Returns:
        a new PreparedStatement object, containing the pre-compiled SQL statement, that will have the capability of returning auto-generated keys
        Throws:
        java.sql.SQLException - if a database access error occurs, this method is called on a closed connection or the given parameter is not a Statement constant indicating whether auto-generated keys should be returned

                                            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 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 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().

        sql - an SQL statement that may contain one or more '?' IN parameter placeholders
        columnIndexes - an array of column indexes indicating the columns that should be returned from the inserted row or rows
        Returns:
        a new PreparedStatement object, containing the pre-compiled statement, that is capable of returning the auto-generated keys designated by the given array of column indexes

      • prepareStatement

        public java.sql.PreparedStatement prepareStatement​(java.lang.String sql,
                                                   java.lang.String[] columnNames)
                                            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. 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 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().

        Specified by:
        prepareStatement in interface java.sql.Connection
        Parameters:
        sql - an SQL statement that may contain one or more '?' IN parameter placeholders
        columnNames - an array of column names indicating the columns that should be returned from the inserted row or rows
        Returns:
        a new PreparedStatement object, containing the pre-compiled statement, that is capable of returning the auto-generated keys designated by the given array of column names
        Throws:
        java.sql.SQLException - if a database access error occurs or this method is called on a closed connection

                   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.

        • ApplicationName - The name of the application currently utilizing the connection
        • ClientUser - The name of the user that the application using the connection is performing work for. This may not be the same as the user name that was used in establishing the connection.
        • ClientHostname - The hostname of the computer the application using the connection is running on.
        Specified by:
        setClientInfo in interface java.sql.Connection
        Parameters:
        name - The name of the client info property to set
        value - The value to set the client info property to. If the value is null, the current value of the specified property is cleared.
        Throws:
        java.sql.SQLClientInfoException - if the database server returns an error while setting the client info value on the database server or this method is called on a closed connection

        Returns a list containing the name and current value of each client info property supported by the driver. The value of a client info property may be null if the property has not been set and does not have a default value.
        Specified by:
        getClientInfo in interface java.sql.Connection
        Returns:
        A Properties object that contains the name and current value of each of the client info properties supported by the driver.
        Throws:
        java.sql.SQLException - if the database server returns an error when fetching the client info values from the database or this method is called on a closed connection

      • setClientInfo

        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.

        Specified by:
        setClientInfo in interface java.sql.Connection
        Parameters:
        properties - the list of client info properties to set
        Throws:

                             throws java.sql.SQLException
        Factory method for creating Array objects. Note: When createArrayOf is used to create an array object that maps to a primitive data type, then it is implementation-defined whether the Array object is an array of that primitive data type or an array of Object. Note: The JDBC driver is responsible for mapping the elements Object array to the default JDBC SQL type defined in java.sql.Types for the given class of Object. The default mapping is specified in Appendix B of the JDBC specification. If the resulting JDBC type is not the appropriate type for the given typeName then it is implementation defined whether an SQLException is thrown or the driver supports the resulting conversion.
        Specified by:
        createArrayOf in interface java.sql.Connection
        Parameters:
        typeName - the SQL name of the type the elements of the array map to. The typeName is a database-specific name which may be the name of a built-in type, a user-defined type or a standard SQL type supported by this database. This is the value returned by Array.getBaseTypeName
        elements - the elements that populate the returned object
        Returns:
        an Array object whose elements map to the specified SQL type
        Throws:
        java.sql.SQLException - if a database error occurs, the JDBC type is not appropriate for the typeName and the conversion is not supported, the typeName is null or this method is called on a closed connection

        attributes - the attributes that populate the returned object
        Returns:
        a Struct object that maps to the given SQL type and is populated with the given attributes

      • unwrap

        public <T> T unwrap​(java.lang.Class<T> iface)
             throws java.sql.SQLException
        Returns an object that implements the given interface to allow access to non-standard methods, or standard methods not exposed by the proxy. If the receiver implements the interface then the result is the receiver or a proxy for the receiver. If the receiver is a wrapper and the wrapped object implements the interface then the result is the wrapped object or a proxy for the wrapped object. Otherwise return the the result of calling unwrap recursively on the wrapped object or a proxy for that result. If the receiver is not a wrapper and does not implement the interface, then an SQLException is thrown.
        Specified by:
        unwrap in interface java.sql.Wrapper
        Parameters:
        iface - A Class defining an interface that the result must implement.
        Returns:
        an object that implements the interface. May be a proxy for the actual implementing object.
        Throws:
        java.sql.SQLException - If no object found that implements the interface

      • isWrapperFor

        public boolean isWrapperFor​(java.lang.Class<?> iface)
        Returns true if this either implements the interface argument or is directly or indirectly a wrapper for an object that does. Returns false otherwise. If this implements the interface then return true, else if this is a wrapper then return the result of recursively calling isWrapperFor on the wrapped object. If this does not implement the interface and is not a wrapper, return false. This method should be implemented as a low-cost operation compared to unwrap so that callers can use this method to avoid expensive unwrap calls that may fail. If this method returns true then calling unwrap with the same argument should succeed.
        Specified by:
        isWrapperFor in interface java.sql.Wrapper
        Parameters:
        iface - a Class defining an interface.
