It is possible for the < code class = "methodname" > DBcursor-> close()< / code > method to return < a href = "../../programmer_reference/program_errorret.html#program_errorret.DB_LOCK_DEADLOCK" class = "olink" > DB_LOCK_DEADLOCK< / a > ,
signaling that any enclosing transaction should be aborted. If the
application is already intending to abort the transaction, this error
should be ignored, and the application should proceed.

After the < code class = "methodname" > DBcursor-> close()< / code > method has been called, regardless of its return value,
you can not use the cursor handle again.

It is not required to close the cursor explicitly before closing the database handle or the transaction handle that owns this cursor
because, closing a database handle or a transaction handle closes those open cursors.
< / p >
< p >
However, it is recommended that you always close all cursor handles immediately after
their use to promote concurrency and to release resources such as page locks.

The < code class = "methodname" > DBcursor-> close()< / code > < span >
