*.tst

The disk contains a series of test scripts for many of the PL/Vision packages. They are generally named PKG.tst where PKG is the name of the package. Examples are PLVtrc.tst and PLVexc.tst. You can use these as a starting point for executing and trying out the PL/Vision packages.

A stored function which uses PLVfile to locate a specific line in a file and then return a value extracted from that line.

PLVexc1.spp

The first version of PLVexc the author developed to provide high-level exception-handling capabilities. It is interesting to compare this iteration with the final version to see how the capabilities of PLVexc grew increasingly abstract and declarative.

code.sql

Shortcut for executing PLVvu.code to see the source code for a stored object.

creind.sql

dispfile.sql

Displays the contents of a file using UTL_FILE and DBMS_OUTPUT (well, actually using the PL/Vision packages that in turn use those builtin packages).

dumpemp.sql

Demonstration of use of PLVio to dump the contents of the emp table to a PL/SQL table (the PLVio target repository).

dumpprog.sql

Dumps an program stored in the database out to an operating system file.

dumpprog.sql

Dumps the source code for a program into an operating system file using the PLVfile package.

dynps.sql

Demonstration of need to declare data structures as globals (in a package specification) if you are going to reference that data in a dynamically constructed PL/SQL block.

dynvar.sql

Demonstration of code required to dynamically create a package containing a global variable, including use of PLVtmr to calculate performance of this action.

errm.sql

Shortcut to execute PLV.errm to display the error message for an error code.

execall.sql

Grants execute authority on the specified program unit to PUBLIC and then creates a public synonym for that program.

Shortcut to generate a function using the PLVgen.func program generator.

gendesc.sql

Demonstration of use of PLVobj.loopexec and dynamic PL/SQL to generate a script that outputs a DESC statement for each specified object.

gentkn.sql

Script that generates INSERT statements for the PLV_token and PLV_token_type tables.

inline2.sql

Another version of inline that relies on PLVio to do the same job and requires much less code.

inlog.sql

Script to display the contents of the default PL/Vision log.

inrfrnc.sql

Displays the contents of the PLVrfrnc table for a particular program.

insrc.sql

Quick glance at the contents of PLV_source, the default repository for source code when writing to a database table.

intree.sql

login.sql

Sample startup script for SQL*Plus (for PL/SQL Release 2.2 or earlier).

login23.sql

Sample startup script for SQL*Plus (for PL/SQL Release 2.3 or later).

modprs.sql

Shortcut script to generate and display the PL/SQL parser (via PLVprsps) of the specified program unit. The second argument of the script allows you to specify the type of identifiers to be retained in the parse. See the PLVprsps specification for the valid options for the second parameter.

sherr.sql

Shortcut for a call to the PLVvu.err procedure. Accepts a single argument, the program for which you want to display errors.

showerr.sp

An early version of the PLVvu.err procedure; this stored procedure displays error information.

showerr.sql showerr1.sp showerr2.sp

Different implementations of scripts that provide an alternative to the SHOW ERRORS command of SQL*Plus

showlog.sql

Another version of "show objects" that accomplishes the same task with a higher-level PLVobj element, vu2pstab.

Quick and simple display of the specified lines (start and end range) source code for a particular program. You can also use PLVvu.code to take advantage of the full range of features of that utility.

ssoo.sql
