call and is available as the Variable. type for variables containing Oracle objects. The object type may be called directly and serves as an alternative way of. Any outstanding changes will be rolled back when the connection object is. If None or the same string object is passed in again, the cursor will execute that.

This constant is used to specify that the subscription should cx_ofacle automatically unregistered after the first notification is received. Added module level method makedsn which creates a data source name given the host, port and SID. Verify that Oracle objects bound to cursors, fetched from cursors, set in object attributes or appended to collection objects are of the correct type. The waitTimeout parameter is expected to be an integer, if specified, and sets the length of time in milliseconds that the caller should wait for a session to become available in the pool before returning with an error.
This parameter defaults to False and indicates whether threaded mode ought to be used. The edition parameter is expected to be a string if specified and sets the edition to use for the session. This constant is used to specify that dequeue should read and obtain a write lock on the message for the duration cx_oraxle the transaction equivalent to a select for update statement. It is primarily provided to facilitate testing the creation of a connection using the OCI service context handle.
Note that support for distributed transactions is buggy when crossing major version boundaries Oracle 8i to Oracle 9i for example. In this case an ORA is returned and the connection will no longer be usable.

Correct handling of objects when dynamic binding is performed. Ensure that a call to setinputsizes with an invalid type prior to vx_oracle call to dicumentation does not result in a type error, but instead gracefully ignores the call to setinputsizes as required by the DB API issue This read-only attribute specifies the list of variables created for the last query that was executed on the cursor.
Check variable array size when setting variable values and raise IndexError, as is already done for getting variable values. Without parameters, this explicitly begins a local transaction; otherwise, this explicitly begins a distributed global transaction with the given parameters.
Calling this function will raise a NotSupportedError exception. Return a new Oracle object of the given type. If this attribute is None, the default behavior will take place for all columns fetched from cursors.
This new feature could be useful if you are bundling up applications and want to include the Oracle Instant Client. For this reason, it is generally recommended to bind parameters by name instead of by position.
Connection Object — cx_Oracle documentation
OCI cx_oraclee that both encoding and nencoding have values or that both encoding and encoding do not have values. Return the element at the specified index of the collection. When a connection is used as a context manager, the connection is now closed when the block ends.
Note If you plan to use callfunc then be aware that the first parameter in the list refers to the return value of the function. Adjusted documentation to provide cx_orracle information on the use of Cursor. Added support for specifying both input and output converters docu,entation variables Added support for specifying the array size of variables that are created using the cursor. Remove date checking from the native docjmentation since Python already checks that dates are valid; enhance error message when invalid dates are encountered so that additional processing can be done.
Added support for fixed char, old style varchar and timestamp attribute values in objects. SessionPool along with the new parameter waitTimeout.
Return a connection object. If no round-trip is required, the operation will never be interrupted.
This read-write attribute specifies a method called for each value that is bound to a statement executed on any cursor associated with this connection. The microseconds are now displayed in datetime variables when nonzero similar to method used in the datetime module. Currently 2, which means that threads may share the module and connections, but not cursors.
The maxLifetimeSession parameter is expected to be an integer, if specified, and sets the maximum length of time in seconds a cx_orace session may exist. It is only relevant if both the client and the database are at least Oracle Database In that case sessions with the specified tag will be preferred over others, but if no such sessions are available a session with a different tag may be returned instead.
Added additional test cases and samples. More will follow in future releases.
