SQL & PL/SQL :: Track Department Change - Update A Counter
Jun 22, 2011
I am trying to track an employee's department changes by adding a Department change counter which is set to 1 whenever the department changes otherwise it is set to a 0. How can I accomplish this update of the counter? Below is the table creation sql and sample data for insert.
CREATE TABLE EMPL_DEPT
(EMPLID VARCHAR2(11) NOT NULL,
EFFDT DATE,
EFFSEQ SMALLINT NOT NULL,
EMPL_RCD SMALLINT NOT NULL,
DEPT_ID VARCHAR2(12) NOT NULL,
[code]..........
In our architecture, the application can only access functions/procedures to access/modify data. Each function logs the action, the executed sql statement, oracle error, user terminal, and the user into a unified log table by using v$ tables to create a general log function that is called after execution or error.
The only advantage is that it will be easier to know the delete and last update information faster versus space and design modification.
create table units (id number primary key , agent number, constraint agnent_fk foreign key (agent) references agent_lookup (id) )create table agent_lookup (id number primary key , agent_name varchar2 (40))INSERT INTO AGENT_LOOKUP (ID, AGENT_NAME) VALUES (1, 'X1'); INSERT INTO AGENT_LOOKUP (ID, AGENT_NAME) VALUES (2, 'X2'); INSERT INTO AGENT_LOOKUP (ID, AGENT_NAME) VALUES (3, 'X3');INSERT INTO UNITS (ID, AGENT) VALUES (100, 1); INSERT INTO UNITS (ID, AGENT) VALUES (101, 2); INSERT INTO UNITS (ID, AGENT) VALUES (102, 3);I want to make units table uses user_lookup table instead of agent_lookup table; where user_lookup contains the same names that exist on agent_lookup, but with different IDs.
create table user_lookup ( id number primary key , user_name varchar2 (40))INSERT INTO USER_LOOKUP (ID, USER_NAME) VALUES (10, 'X1'); INSERT INTO USER_LOOKUP (ID, USER_NAME) VALUES (20, 'X2'); INSERT INTO USER_LOOKUP (ID, USER_NAME) VALUES (30, 'X3');So, I need to update the table units and SET the value of Agent to the ID column of the user_lookup table .
I thought of this, but sure it will not work:
update units ut set ut.agent = (select u.id from user_lookup u where agent_lookup.agent_name = u.user_name ) where ut.agent = agent_lookup.id
I have a report that comes from SQL Query (updateable report). I'm using the apex_item.text and apex_item.hidden on fields. I'm using a button to submit and after submit process to add some logic that I need.
There could be 1 - 10 records in the report. There is only 1 field that is needed to enter a value, but the value of this field determines the value of another field. I think that I can do this with a submit button and an after submit process where I loop through all the records. I think I have this handled.
This is the question
When the value of that field is changed then the value of another field in the same row changes immediately. All the examples I've seen so far are for a single record and that doesn't work for us.
I guess this is a MRU process but I haven't seen an example where a dynamic action is possible on a Multi Row Update.
I need to enhance the design of one of the tables by adding a primary key to it. i need to know how to fill this new column with sequenced serial before I change it to Primary key.
CREATE TABLE AFESD.REQUEST_TO_FINANCE ( REFERENCE_NUMBER CHAR(10 BYTE) NOT NULL, ISSUE_DATE DATE NOT NULL, RECEIPT_DATE DATE NOT NULL, DESCRIPTION VARCHAR2(250 BYTE), FK_COUNTRYCODE NUMBER(3) NOT NULL );
ALTER TABLE N_REQUEST_TO_FINANCE ADD REQUEST_SERIAL NUMBER(6);
Now I need to add values to REQUEST_SERIAL but can figure how to do that in SQL. I even tried to use your previous tip and use row_number() but it can only return a full set of values not a single one.
But if I put l_my_arr(l_year) := 0, immediately after FETCH, then the counter is always 1, and I cannot put it before because l_year has to be FETCHED.
I'm wondering how I can use a counter to number records in a table I'm inserting into. I need the counter to reset based on changing data in my table. For example, I have the following
seq_number name_type 1 Short Name 1 Short Name 1 Short Name 2 Short Name 2 Short Name
I'd like my results to be the following: seq_number name_type 1 Short Name - 1 1 Short Name - 2 1 Short Name - 3 2 Short Name - 1 2 Short Name - 2
I'd like my counter to increment so that I can add a sequence number to the end of my name type, but when my seq_number field changes I'd like to reset and restart my counter.
I been looking high and low for a way to get the default record counter, at the bottom of the window, to provide how many records have been returned by any query.You know the record 1/? or record 1/10 at the bottom.
I don't want to do an: execute_query; last_record; first_record;
Nor do I want to set the "query All Records" property of the data block to "Yes". Both result in the form opening up way too slow. I've a table with a total of 29500+ rows.
I have a plsql Proc, which accepts a few parameters and inevitably loops through a cursor and runs a bunch of insert statements. With quite a few IF conditions.
Each insert statement has a value which i want to increment by (+1) every time an insert statement is executed in the same loop.. This is for a student housing database and this is for their room preferences so 1 is the first, 2 is there second preference e.t.c.
Please take a look at the code below: in the Insert values() I have put a? Where I want the number to increment from.
There are a lot more inserts which I haven't put below. I hope I have made myself clear as this has been quite difficult to explain. So for example if the 2nd two inserts are run, then I was the first one to insert with a 1 and the second with a 2.
BEGIN FOR rec IN c1 LOOP IF c1%FOUND THEN INSERT INTO table (PK_A, fk_rms_id, application_type, application_person_type) VALUES (NULL, rec.pk_rms_id, app_type, app_person_type) RETURNING PK_APPLICATION_NO INTO x; [Code] ........
I am trying to create view that selects a number of rows from a table and has a calculated field which is a counter form 1 to n next to each row.
In the below example, s_name is repeated many times each with a differnet serial, I want to cteate a view that shows a counter for the occurences of s_name next to the serial.
CREATE TABLE XYZ ( SERIAL NUMBER PRIMARY KEY, S_NAME VARCHAR2(30) ); INSERT ALL INTO XYZ VALUES (1, 'ABC') INTO XYZ VALUES (11, 'ABC')
I want to increment a counter in a loop based on a condition.
Here is how my xml looks like
<result> <resultset id=1> <value>
[Code]....
I need to look at each and every resultset and check if the value is >400 and if it is then display some text. Something like this
<outputvalue> Yes, there is a value greater than 400 </outputvalue>
In my XSL, I declared a variable called count with value 0. I created a for-loop which goes through these results. Then inside the loop there is a condition to cehck if the value is > 400. If the value is >400, then the counter is incremented.
that I need to insert into Child using seq_parent but I want to insert the same sequence for each group of rRef. I dont know how to do that using SQL not PL/SQL.
I have a form which contains some block (each block with some text item, two radio groups and a list item). I want to enable/disable and set visible property as true/false for first to last items of each block conditionally. I can do that for all items but radio buttons.
Because to set item or radio button property I need to pass that items ID or Name as parameter. I can get items name/type using get_block_property and next item of that item using get_item_property but unable to get radio button ID/Name using get_radio_button_property or any other built in. To execute get_radio_button_property or set_radio_button_property I need to pass radio button ID/Name. So, how I track radio button id or name in oracle forms? Is it limitations of Oracle forms?
we have a database application which is done frequently.in these we load data throught Sql loader, we create an DB instances, we do several DML operation on the database.
now for such task in an application we need to keep an logging track of each task performed in PL/SQl procedure packages.
I have two Oracle databases (test1- 10gr2,test2 - 11gr2) on rhel 5.5. is it possible to find which particular oracle process belongs to which home from OS level. was trying to find which db processes are consuming more resources on my host.
I have a trigger program to track updated information's on perks column. I am failing to finish systime in my trigger program.

What could be the reasons that some queries execute fast when executed on sqlplus on server, whereas the same queries run slower with same input values fed from application screen?
One issue I guess would be bind variable peeking while using application whereas executing from sqlplus is causing hard parsing and thus getting rid of "peeking"
If displaying the data on application screen is taking time after data has been fetched, where I can see this delay?
I understand the elapsed time under 'Fetch' in tkprof will show time taken to fetch from database and not the time taken to be displayed in the application GUI
finally how to set arraysize in jdbc to improve performance by reducing roundtrips?
I have three blocks in my form , header,activity and item.One header can have many activities and one activity can have many items.I need to keep track of item value totals in header from items under each activity.
I was given a task by manager to keep track of changes on a given table including os_user who made it.Should I create a trigger on it (on any update, insert, delete etc.) or there is a better way of doing it ?I think there could be some info already in some data dictionary views or something like it.
I have employee interface table something like this.
emp_idemp_name Job_title supervisor_name 1AJ Engineer BJ 2CK Analyst ND 3BJ Manager TR 5TR VP IT JD 6ND S Manager MD 7MD VP Telecom SK 8SK VP Eng JR
I want to idenitfy the VP for each employee. The logic I have to apply is check for hte supervisor of each employee to see if the supervisor has designation starting with 'VP'. If no, I have check the supervisor of the supervisor and so on. I tried using a recursive query using connect_by_root but in the above example for employee ND it lists the VP as both MD and SK. I need it to show on MD who is the lower in the hierarchy.
I am a Java person but since my app uses the Oracle DB I am to do this task.
