Syntax

Key_ID ('Key_Name')

Arguments

  • 'Key_Name'
    The name of a symmetric key in the database.

Return Types

int

Remarks

The name of a temporary key must start with a number sign (#).

Permissions

Because temporary keys are only available in the session in which they are created, no permissions are required to access them. To access a key that is not temporary, the caller needs some permission on the key and must not have been denied VIEW permission on the key.

Examples

A. Returning the ID of a symmetric key

The following example returns the ID of a key called ABerglundKey1.

SELECT KEY_ID('ABerglundKey1')

B. Returning the ID of a temporary symmetric key

The following example returns the ID of a temporary symmetric key. Note that # is prepended to the key name.

SELECT KEY_ID('#ABerglundKey2')
