How to track commenting pattern and others custom pattern inside procedure or function about plscope-utils HOT 7 CLOSED

Could you please provide an example? E.g. as source snippet and what you are looking for.

from plscope-utils.

Suppose I have a subtype declared in some package say pkgsubtype" and I am declaring a local variable based on that in my all proc as this is standard I want to follow in my procedure.

Declare
v_procname pkgsubtype.proc_name;

It migh happended a new joinee is unaware of something like this and created his own declaration like below

v_procname varchar2(50);

Which is my area of pain as I want identify custom code like this as error.
In brief above was just a sample my intention is to find any specific pattern if someone is deviating from that than it should be marked as not ok.
Hope this clear your doubt. I know its not straight forward but just wondering if this can be done.

Also How to check naming convention for constraint,PK,FK etc ..? Is their any provision ?

Let's create some example code

CREATE OR REPLACE PROCEDURE good IS
   l_dname dept.dname%type;
BEGIN
   NULL;
END;
/

CREATE OR REPLACE PROCEDURE bad IS
   l_dname VARCHAR2(100);
BEGIN
   NULL;
END;
/

CREATE OR REPLACE PACKAGE mytypes IS
   SUBTYPE dname_type IS VARCHAR2(14 BYTE);
END;
/

CREATE OR REPLACE PROCEDURE good2 IS
   l_dname mytypes.dname_type;
BEGIN
   NULL;
END;
/

and here's a PL/Scope which reduces the results to relevant columns and declared variables:

SELECT p.name, c.type AS ref_type, c.name AS ref_name, c.text
  FROM plscope_identifiers p
  JOIN plscope_identifiers c
    ON p.owner = c.owner
       AND p.object_type = c.object_type
       AND p.object_name = c.object_name
       AND p.usage_id = c.usage_context_id
 WHERE p.type = 'VARIABLE'
   AND p.usage = 'DECLARATION'
   AND p.object_name IN ('BAD','GOOD', 'GOOD2');

The result of the query is

NAME            REF_TYPE             REF_NAME        TEXT                               
--------------- -------------------- --------------- -----------------------------------
L_DNAME         TABLE                DEPT               l_dname dept.dname%type;        
L_DNAME         PACKAGE              MYTYPES            l_dname mytypes.dname_type;     
L_DNAME         CHARACTER DATATYPE   VARCHAR2           l_dname VARCHAR2(100);      

You may now filter the result based on REF_TYPE. Please have a look at the PL/Scope documentation to find other values expected in REF_TYPE. Filtering on CHARACTER DATATYPE will not be enough for all use cases.

Please open another issue regarding naming conventions. Just to avoid mixing things in this thread. Thanks.

Thanks Phillips but how to include same in plscope_naming view? .What if that pattern doesn't exists in declaration part and exists in body part of any procedure /pkg/function and that can be any custom code e.g.
I want to search for a specific pattern in my code like what pattern team has used for commenting

/*Multi line code
comments with single start
*/

or

/** double start comments**/

or

--Single line comments

and suppose I want to restrict team to use only /** */ pattern and not others and I want this to be included in plscope_naming view and I can set the COMMENT_REGEXE

exec plscope_context.set_attr('COMMENTS_REGEXE','(.**//.)|(/*.)|(--.*)|(((/*)+?[\w\W]+?(*/)+))');

Please advise.

PL/Scope is not a full parsing solution. It just reports identifiers and SQL statements during parse time with some context information.

Comments are not covered by PL/Scope. Hence you need to parse the comments from dba_source or from source files yourself. BTW the regex will become a bit more complex since you have to exclude comments in string literals.

So, there are no plans to cover comments in plscope-utils.
