db cursor

						db cursor
						[-txn txnid]
					

Description

The db cursor command creates a database cursor. The returned cursor handle is bound to a Tcl command of the form dbN.cX, where X is an integer starting at 0 (for example, db0.c0 and db0.c1). It is through this Tcl command that the script accesses the cursor methods. The options are as follows:

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

In the case of error, a Tcl error is thrown.
