Data dcitioany view and function and procedures insure a package

Question

I need the run a query on the Data dcitioany, to get a list of packages as well as a list for procedures and functions inside on Oracle 10g

Answer 1

I use DBA_SOURCE,
I used like this
  SELECT v.owner,
       (CASE V.type
        WHEN 'FUNCTION'  THEN NULL
        WHEN 'PROCEDURE' THEN NULL
        ELSE v.name
        END
       )PACKAGE_NAME ,
        UPPER(
        SUBSTR
        TRANSLATE(
        LTRIM(REPLACE(SUBSTR(ltrim(v.text),LENGTH('PROCEDURE')+1),'"',''),' '),
        '+++'
        ),---TEXT TO BE SEARCH
        1,---STARTING POSITION
        INSTR(
        TRANSLATE(
        LTRIM(REPLACE(SUBSTR(ltrim(v.text),LENGTH('PROCEDURE')+1),'"',''),' '),
        '+++'
        ||'+'
        '+'
        )-1 ---lENGTH
        )OBJECT_NAME
        TRIM(SUBSTR(ltrim(v.text),1,LENGTH('PROCEDURE')))"TYPE"
FROM dba_source v
WHERE (TRIM(ltrim(v.text)) LIKE ('FUNCTION%') OR TRIM(ltrim(v.text)) LIKE ('PROCEDURE%')) AND
            v.type IN ('PACKAGE','FUNCTION','PROCEDURE')
ORDER BY V.OWNER,V.name,v.text;Note: the translate, substr, etc function can be simplified based on your needs
in my case, how developers created the function and procedure is quite messy.
thanks
