table_1 contain records on employee and the supervisor they are under at a certain date.
As some employee(00001 & 00003) have a different supervisor from different date, I'll like to extract from table_1 the record of each employee in the table that only contain the supervisor info on the most recent date.And from table_2, i'll like to extract the employee's name. These records extracted from both the tables would the be put into a new table,table_3
Example: For employee 00001, only extract record that have the most recent date which is 04-APRIL-2004 and not on 01-MARCH-2004
table_3

View 6 Replies View RelatedSQL & PL/SQL :: Query To Update Current Value In DBA View To New One
Jul 18, 2012I am looking to build a query to update a current value in a DBA view to a new one.i.e. updating directories based on the current value:
CREATE OR REPLACE DIRECTORY 'DIRECTORY_NAME' AS 'DIRECTORY_PATH'(substr(directory_path, 1,5) + '/&dbname' {i.e. this is different for every database name }+ 'DIRECTORY_PATH'(string after /xyz/)
WHERE DIRECTORY_NAME in
( select DIRECTORY_NAME
from DBA_DIRECTORIES
WHERE DIRECTORY_PATH
like '/xyz/%'
)
i.e. resulting output should be:
CREATE OR REPLACE DIRECTORY 'ABC' AS '/xyz/DBNAME/abc/def/';
(when the directory previously was 'xyz/abc/def/') i.e. basically inserting the db name into the directory.where DBNAME is a variable more directories are added frequently so therefore this needs to be a dynamic procedure to change the directories in the db.
