<b>Description(db count)</b>
|
|
<p>The <i>db</i> <b>count</b> command returns a count of the number of duplicate
|
|
data items for the key given. If the key does not exist, a value of 0
|
|
is returned. If there are no duplicates, or if the database does not
|
|
support duplicates, but a key/data pair exists, a value of 1 is
|
|
returned. If an error occurs, a Berkeley DB error message is returned or a
|
|
Tcl error is thrown.</p>
