ALTER VIEW

The ALTER VIEW statement regenerates a view using an existing view definition at the current server.

Restriction: This topic applies to Windows environments only.

The XDB Server operating environment only provides syntax support for this statement at this time.

Invocation

This statement can be embedded in an application program or issued interactively. It is an executable statement that can be dynamically prepared only if DYNAMICRULES run behavior is implicitly or explicitly specified.

Authorization

The privilege set that is defined below must include at least one of the following:

Ownership of the view
SYSADM authority
SYSCTRL authority

If the statement is embedded in an application program, the privilege set is the privileges that are held by the authorization ID of the owner of the plan or package. If the statement is dynamically prepared, the privilege set is the union of the privilege sets that are held by each authorization ID of the process.

Syntax

Bold text indicates clauses or options that are supported only syntactically.
