db del

						db del
						[-glob]
						[-txn txnid]
						key
					

Description

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.

• -txn txnid If the file is being accessed under transaction protection, the txnid parameter is a transaction handle returned from env txn.

The db del command returns 0 on success, and in the case of error, a Tcl error is thrown.
