com.sas.rio
Class MVAConnection

com.sas.rio.MVAConnection

All Implemented Interfaces:

java.sql.Connection, java.sql.Wrapper

public class MVAConnection
implements java.sql.Connection

A Connection represents a session with a specific database. Within the context of a Connection, SQL statements are executed and results are returned.

A Connection's database is able to provide information describing its tables, its supported SQL grammar, its stored procedures, the capabilities of this connection, etc. This information is obtained with the getMetaData method.

Note: By default the Connection automatically commits changes after executing each statement. If auto commit has been disabled, an explicit commit must be done or database changes will not be saved.

Constructor Detail

MVAConnection

public MVAConnection(java.lang.String url,
                     java.util.Properties info)
              throws java.sql.SQLException

Constructs an MVAConnection object.

Parameters:

url - initial input url containing host and port information.

info - java.util.Properties object which contains:

userName

MVA server access user name

password

MVA server access password

librefs

a semicolon delimited list of 'name filepath'.

encryptionPolicy

whether or not JavaBridge should attempt to negotiate with the server over which encryption algorithm to use and what to do if the negotiations fail. Possible values:

none

do not use encryption. This is the default.

optional

attempt to use encryption but, if algorithm negotiation fails, continue with an unencrypted session

required

attempt to use encryption but, if algorithm negotiation fails, fail the connection

encryptionContent

specifies which messages should be encrypted if encryption is used. Possible values:

all

encrypt all messages. This is the default.

authentication

encrypt only messages that contain user name and password information.

encryptionAlgorithms

the list of algorithms you are willing to use in order of preference. Values in the list should be separated by commas and chosen from sasproprietary, rc2, rc4, aes, des, or tripledes. If no value is specified, then one of the server's favorite algorithms will be used.

applyFormats

specifies whether or not column formats are applied when retrieving data. If the value is true, all data is returned as Strings. For any column, the format used is the one defined on the column in the data set. If "applyFormats" is set to false (the default case) no formatting is applied.

segmentLength

Specifies the segment length value, in bytes, for character annotations when initially added to a SAS result set. This property is not used with result sets that already have annotations. The server uses the segment length to define the buffer width of character extended attribute values. These values can span multiple segments. The default value of the segment length is 256 bytes.

Note that the server's encryption policy is, by default, optional so no special action is needed to prepare an IOM BRIDGE server to use encryption. However, it is possible to set up the server so that encryption is required. Consult IOM BRIDGE server documentation for details.

getClientInfo

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

The MVAConnection implementation of getClientInfo always returns an empty properties object. The IOM JDBC Driver does not support the ability to set or retrieve client info properties.

createArrayOf

public java.sql.Array createArrayOf(java.lang.String typeName,
                                    java.lang.Object[] elements)
                             throws java.sql.SQLException

This method is not supported.

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 - Always thrown, to indicate that this method is not implemented.

createStruct

public java.sql.Struct createStruct(java.lang.String typeName,
                                    java.lang.Object[] attributes)
                             throws java.sql.SQLException

The MVAConnection implementation of createStruct(String, Object[]) always throws a SQLFeatureNotSupportedException. Base SAS does not support SQL structured types.
