4.7 NDS Utility PackageTo make it easier for my readers to take advantage of the various generic utilities discussed in this chapter, I have created a single package called ndsutil. This package, available on the companion disk in ndsutil.pkg, contains the programs listed in Table 4.1 .
The package is defined using the invoker rights mode (AUTHID CURRENT_USER). This means that no matter who owns the package, any external references in the dynamic SQL you execute via ndsutil are resolved according to the authority of the invoking schema, not the owner. All programs contain exception sections that display the error and the offending SQL. Procedures then reraise the error, whereas functions generally return NULL or a NULL/empty structure.
