SQL & PL/SQL :: Select Updated Rows From One Table
Jul 13, 2013
There are two tables like I posted below.I want a SQL query which selects all the rows from TABLE A which are not present in TABLE B. Also the select statement should pick all those rows which has updated value of COL_A2 in TABLE A.
TABLE A
COL_A1COL_A2
AAAMOBILE
BBBTABLET
CCCDESKTOP
DDDUNKNOWN
TABLE B
COL_B1COL_B2
AAAMOBILE
BBBUNKNOWN
CCCDESKTOP
The select statement should return following rows from TABLE A
I want to know like How we can select the latest updated record from xyz table. that record has STATUS column. I also want to check if the status is RED or GREEN query should return if the status is red then 1 and if the status is GREEN then it should return 0
The following code is indicative of what I'd like to do (as in not correct at all ). Would there be a more immediate way to accomplish this other than executing a SELECT statement after the UPDATE?
-- Incorrect indicative example 1.
DECLARE v_cur SYS_REFCURSOR; BEGIN UPDATE table1(f1, f2) SET ('v1', 'v2') WHERE f3 = 'v3' RETURNING <updated_rows> INTO v_cur END;
-- Incorrect indicative example 2.
DECLARE v_cur SYS_REFCURSOR; BEGIN OPEN v_cur FOR UPDATE table1(f1, f2) SET ('v1', 'v2') WHERE f3 = 'v3' END;
I need to view the rows of the result of a select query in table format in GUI application.I have used XMLELEMENT to somewhat match the scenario to display as ','(comma) separate values as b belwo
I want to know that How to find which table got last updated and how to find last DDL and DML operation obtained in which table? here I know the table name
SQL> SELECT LAST_DDL_TIME FROM DBA_OBJECTS WHERE OBJECT_NAME='PREM';
LAST_DDL_ --------- 20-MAR-12
SQL> TRUNCATE TABLE PREM;
Table truncated.
SQL> SELECT LAST_DDL_TIME FROM DBA_OBJECTS WHERE OBJECT_NAME='PREM';
LAST_DDL_ --------- 10-APR-12
Note: With out enable the auditing I want to know that .
when the tables are updated, the following detals must be correct to ensure that the links in the affected tables are in place.
PLUPDATE_NEW(PLUP_SAVE_SEQ field value) must be the same with PLUPDATE_BENEF_NEW (PLUP_NEW_BENEF_SAVE_SEQ field value) PLUPDATE_OLD(PLUP_SAVE_SEQ field value) must be the same with PLUPDATE_BENEF_OLD (PLUP_OLD_BENEF_SAVE_SEQ field value)?
[Code]....
i tried this code, what should i do in the link for this tables?
The requirement is, the combination of col1,col2,col3 and col4 should always be unique, and wherever the col1, col2,col3 are same then col4 should be the sequence, starting from 1. Likewise the data should be updated back to the table.I'm able to do this using PL/SQL. Can I do the same using a single update statement?
I have approximately 1200 transaction to be updated to a master table. There are other columns in the master table but only one column is being updated. I would like to use sqlloader if possible or any other efficient means. Those 1200 record is stored in an excel spreadsheet. The col1 of the excel spreadsheet have to match col1 of the master table inorder for update col2 from the excel spreadsheet. Here is an example of the data. My operation system is HPUX and database is Oracle 10g.
Master table col1 col2 col3 col 4 4238 susan 56e 5879 h698c rich 12g 7091 joyce 34b 0876 mike 25n 7501 k956b robert 87c 9498 angela 67r 3645 doris 92y
I have a multi record block . I need to implement a functionality where the user updates a field in the record but the form saves the previous version of the record in another table ..
I am having a table with 4 columns as mentioned below
For a particular prod the value greater less than 5 should be rounded to 5 and value greater than 5 should be rounded to 10. And the rounded quantity should be adjusted with in a product starting with order by of rank with in a prod else leave it
I have taken all the records in to a cursor. Once after rounding the request of 1st rank and adjusting the values of next rank is done. Trying to round the value for 2nd rank as done for 1st rank. Its not taking the recently updated value(i,e adjusted value in rounding of 1st rank).
This is because of using a cursor having a value which is of old value. Is there any way to handle such scenario's where cursor records gets dynamically updated when a table record is updated.
I am trying to find records in table A that don't have any corresponding records in table B

I would like to know how to increase the result set of a 'Select' statement? I did a 'Select' that should have returned 36,000 rows and got only 5000 rows. What access level do I need to change this and what do I need to change? I am trying to do a migration of data from a delimited file to a table in Oracle. Yet, the data has to be filtered out prior to loading to the table?
SQLSELECT MIN(major_zipcode) FROM TEMP WHERE MAJOR_CITIES IN (select distinct major_cities from temp);
