11. A computer-readable medium on which is stored a Structured Query Language (SQL) swap alias command, wherein the SQL swap alias command is a single SQL statement that comprises a list of multiple different objects whose aliases are to be swapped and which, when compiled and executed, causes a global alias name swap for multiple objects in a database management system; wherein the SQL swap alias command, when compiled and issued as a compiled SQL swap alias command to an SQL interface for the database management system, performs the steps of: in response to determining that an issuer of the SQL swap alias command is authorized to issue the SQL swap alias command, determining if a particular alias name, for one of the multiple objects, is locked to prevent changing the particular alias name to point to a different underlying table/view; in response to determining that the particular alias name is locked, determining if the issuer of the swap alias command has an authority to force the alias name swap of the particular alias name; in response to determining that the issuer has the authority to force the alias name swap of the particular alias name: swapping alias names for all objects using the particular alias name in the database management system; and concurrently swapping multiple alias names of all non-locked alias names for the multiple objects in the database management system, wherein said swapping is performed as a global alias swap; when the issuer does not have the authority to force the alias name swap of the particular alias name: issuing an error message if the SQL swap alias command fails because the issuer is not authorized to force the alias name swap; and swapping only the alias names of each of multiple other objects whose alias names are non-locked or for which the issuer has authority to force the alias name swap, wherein said swapping is performed as a global alias swap via execution of the compiled SQL swap alias command generated from the single SQL swap alias command.

The computer-readable medium of claim 11 , wherein the SQL swap alias command, when compiled, performs the step of: issuing an error message if the SQL swap alias command fails because the issuer is not authorized to issue the swap alias command.
