db del [-glob] [-txn txnid] key
The db del command removes key/data pairs from the database.
In the presence of duplicate key values, all records associated with the designated key will be discarded.
The options are as follows:
-glob
The specified key is a wildcard pattern, and all keys matching that pattern are discarded from the database. The pattern is a simple wildcard, any characters after the wildcard character are ignored. This option only works on databases using the Btree access method.
-txn txnid
If the operation is part of an application-specified transaction, the txnid parameter is a transaction handle returned from env txn. If no transaction handle is specified, but the operation occurs in a transactional database, the operation will be implicitly transaction protected.
The db del command returns 0 on success, and in the case of error, a Tcl error is thrown.
