setAutoClose

public void setAutoClose(boolean autoClose)
                  throws java.sql.SQLException

Not supported by VORTEXjdbc. When a Connection is in auto-close mode all its PreparedStatements, CallableStatements, and ResultSets will be closed when a transaction is committed or rolled back. By default, a new Connection is in auto-close mode.

When auto-close is disabled JDBC attempts to keep all statements and ResultSets open across commits and rollbacks. However the actual behaviour will vary depending on what the underlying database supports. Some databases allow these objects to remain open across commits whereas other databases insist on closing them.

Parameters:

autoClose - true enables auto-close, false disables auto-close.

                                       throws java.sql.SQLException

Not supported by VORTEXjdbc. Creates a CallableStatement object that will generate ResultSet objects with the given type and concurrency. This method is the same as the prepareCall method above, but it allows the default result set type, result set concurrency type and holdability to be overridden.

Specified by:

prepareCall in interface java.sql.Connection

prepareStatement

public java.sql.PreparedStatement prepareStatement(java.lang.String sql,
                                          int autoGeneratedKeys)
                                            throws java.sql.SQLException

Not supported by VORTEXjdbc. 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. 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.

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 GENESISsql supports only 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 or the given parameter is not a Statement constant indicating whether auto-generated keys should be returned

prepareStatement

public java.sql.PreparedStatement prepareStatement(java.lang.String sql,
                                          int[] columnIndexes)
                                            throws java.sql.SQLException

Not supported by VORTEXjdbc. 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. 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. 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.

Specified by:

prepareStatement in interface java.sql.Connection

Parameters:

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

Throws:

java.sql.SQLException - - if a database access error occurs

prepareStatement

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

Not supported by VORTEXjdbc. 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. 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.

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 exception SQLException - if a database access error occurs

Throws:

java.sql.SQLException

isWrapperFor

public boolean isWrapperFor(java.lang.Class<?> Connection)
                     throws java.sql.SQLException

Specified by:

isWrapperFor in interface java.sql.Wrapper

Throws:

java.sql.SQLException

unwrap

public <T> T unwrap(java.lang.Class<T> Connection)
         throws java.sql.SQLException

Specified by:

unwrap in interface java.sql.Wrapper

Throws:

java.sql.SQLException

getNetworkTimeout

public int getNetworkTimeout()
                      throws java.sql.SQLException

Not supported by VORTEXjdbc. Retrieves the number of milliseconds the driver will wait for a database request to complete. If the limit is exceeded, a SQLException is thrown.

Specified by:

getNetworkTimeout in interface java.sql.Connection

Returns:

the current timeout limit in milliseconds; zero means there is no limit

Throws:

:SQLException - if a database access error occurs or this method is called on a closed Connection

java.sql.SQLFeatureNotSupportedException - - if the JDBC driver does not support this method

java.sql.SQLException

setNetworkTimeout

public void setNetworkTimeout(java.util.concurrent.Executor executor,
                     int milliseconds)
                       throws java.sql.SQLException

Not supported by VORTEXjdbc. Sets the maximum period a Connection or objects created from the Connection will wait for the database to reply to any one request. If any request remains unanswered, the waiting method will return with a SQLException, and the Connection or objects created from the Connection will be marked as closed. Any subsequent use of the objects, with the exception of the close, isClosed or Connection.isValid methods, will result in a SQLException. This method can be invoked more than once, such as to set a limit for an area of JDBC code, and to reset to the default on exit from this area. Invocation of this method has no impact on already outstanding requests. The Statement.setQueryTimeout() timeout value is independent of the timeout value specified in setNetworkTimeout. If the query timeout expires before the network timeout then the statement execution will be canceled. If the network is still active the result will be that both the statement and connection are still usable. However if the network timeout expires before the query timeout or if the statement timeout fails due to network problems, the connection will be marked as closed, any resources held by the connection will be released and both the connection and statement will be unusable. When the driver determines that the setNetworkTimeout timeout value has expired, the JDBC driver marks the connection closed and releases any resources held by the connection. This method checks to see that there is an SQLPermission object before allowing the method to proceed. If a SecurityManager exists and its checkPermission method denies calling setNetworkTimeout, this method throws a java.lang.SecurityException.

Specified by:

setNetworkTimeout in interface java.sql.Connection

Parameters:

executor - The Executor implementation which will be used by setNetworkTimeout.

milliseconds - The time in milliseconds to wait for the database operation to complete. If the JDBC driver does not support milliseconds, the JDBC driver will round the value up to the nearest second. If the timeout period expires before the operation completes, a SQLException will be thrown. A value of 0 indicates that there is not timeout for database operations.

Throws:

java.sql.SQLException - if a database access error occurs, this method is called on a closed connection, the executor is null, or the value specified for seconds is less than 0.

java.lang.SecurityException - if a security manager exists and its checkPermission method denies calling setNetworkTimeout.

java.sql.SQLFeatureNotSupportedException - - if the JDBC driver does not support this method

abort

public void abort(java.util.concurrent.Executor executor)
           throws java.sql.SQLException

Not supported by VORTEXjdbc. Terminates an open connection. Calling abort results in: The connection marked as closed Closes any physical connection to the database Releases resources used by the connection Insures that any thread that is currently accessing the connection will either progress to completion or throw an SQLException. Calling abort marks the connection closed and releases any resources. Calling abort on a closed connection is a no-op. This method checks to see that there is an SQLPermission object before allowing the method to proceed. If a SecurityManager exists and its checkPermission method denies calling abort, this method throws a java.lang.SecurityException.

Specified by:

abort in interface java.sql.Connection

Parameters:

executor - The Executor implementation which will be used by abort.

Throws:

java.sql.SQLException - if a database access error occurs or the executor is null

java.lang.SecurityException - if a security manager exists and its checkPermission method denies calling abort

setSchema

public void setSchema(java.lang.String schema)
               throws java.sql.SQLException

Not supported by VORTEXjdbc. Sets the given schema name to access. If the driver does not support schemas, it will silently ignore this request. Calling setSchema has no effect on previously created or prepared Statement objects. It is implementation defined whether a DBMS prepare operation takes place immediately when the Connection method prepareStatement or prepareCall is invoked. For maximum portability, setSchema should be called before a Statement is created or prepared.

Specified by:

setSchema in interface java.sql.Connection

Parameters:

schema - the name of a schema in which to work

Throws:

java.sql.SQLException - - if a database access error occurs or this method is called on a closed connection

public java.lang.String getSchema()
                           throws java.sql.SQLException

Not supported by VORTEXjdbc. Retrieves this Connection object's current schema name.

Specified by:

getSchema in interface java.sql.Connection

Returns:

the current schema name or null if there is none

Throws:

java.sql.SQLException - if a database access error occurs or this method is called on a closed connectio

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

public java.lang.String getClientInfo(java.lang.String name)
                               throws java.sql.SQLException

Not supported by VORTEXjdbc. Returns the value of the client info property specified by name. This method may return null if the specified client info property has not been set and does not have a default value. This method will also return null if the specified client info property name is not supported by the driver. Applications may use the DatabaseMetaData.getClientInfoProperties method to determine the client info properties supported by the driver.

Specified by:

getClientInfo in interface java.sql.Connection

Parameters:

name - The name of the client info property to retrieve

Returns:

The value of the client info property specified

Throws:

java.sql.SQLException - if the database server returns an error when fetching the client info value from the database or this method is called on a closed connection

getClientInfo

public java.util.Properties getClientInfo()
                                   throws java.sql.SQLException

Not supported by VORTEXjdbc. 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:

setClientInfo

public void setClientInfo(java.lang.String name,
                 java.lang.String value)
                   throws java.sql.SQLClientInfoException

Not supported by VORTEXjdbc. 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 setvalue - 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

setClientInfo

public void setClientInfo(java.util.Properties properties)
                   throws java.sql.SQLClientInfoException

Not supported by VORTEXjdbc. 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:

java.sql.SQLClientInfoException - if the database server returns an error while setting the clientInfo values on the database server or this method is called on a closed connection
