Forms :: Comparing Date In 6i
Aug 3, 2011
I am working in form 6i, database 9i. I have datablock on table t1.
table t1: name(varchar2), date(varchar2)
datablock: name(varchar2), date(varchar2)[i have insert date with time stamp]
for date column, i am inserting date with time stamp.While querying data, user just enters only date(no time stamp), i should be able to query data. I tried in data block where condition
WHERE: substr(date,1,11)=nvl(:block.date,substr(date,1,11)
i am not able to retrieve data through date, through name it's working fine.how to retrieve data by only entering date (without time stamp)

I'm looking to see if there's a solution to my problem that I can use within the context of my business application interface into an Oracle RDMS. I have access to write custom SQL statements and functions, but I am NOT able to create stored procedures using the interface I have.
The challenge I am having is comparing date ranges. I have a table containing two columns labelled START TS TIME and END TS TIME, both of type 'Date'. I have figured out how to query each row against a given Next Session Start and Next Session End and determine if each row overlaps that row.
I need a procedure that will be recursive: that is, set Next Session Start and Next Session End to START TS TIME and END TS TIME of the first row, compare all rows against it, then set Next Session Start and Next Session End to the next row, compare all rows, ... for all rows in the table. I want to know what the maximum number of matches is (i.e. the most time periods that overlap).
If I could use a stored procedure I could complete this query easily. Is there other techniques (i.e. functions) available to leverage in order compare each row of date ranges against ALL rows in the same table?

I have got a table having column a, b , c, d, e and some values are stored in it. e.g. a, c and e have 'Y' and b and d have 'N' value in it.
How can i count with one query , how many columns have 'Y' and how many have 'N'.
cursor is one solution.

A field named xxx_date is a text item which we have to enter manually so as to update a record in that particular date. This is a mandatory field without which we cannot continue the data entry..
I am getting this error while trying to update the record
FRM-40509 :Oracle error :unable to update record
I have kept the enabled = yes
required=no
data type=Date.. in the property pallet

I have a requirement to get the count of those records whose department is not changed since they have joined the organization.
Script:
CREATE TABLE ddumps(orgid NUMBER, orgdate DATE, orgdept VARCHAR2(10))
/
INSERT INTO ddumps VALUES(1,'01-JAN-1999','ORG1')
/
INSERT INTO ddumps VALUES(1,'01-JAN-2000','ORG2')
/
INSERT INTO ddumps VALUES(1,'01-JAN-2001','ORG2')
/
INSERT INTO ddumps VALUES(2,'01-JAN-1999','ORG1')
/
INSERT INTO ddumps VALUES(2,'01-JAN-2000','ORG1')
/
INSERT INTO ddumps VALUES(2,'01-JAN-2001','ORG1')
ORGID ORGDATE ORGDEPT
1 1/1/1999 ORG1
1 1/1/2000 ORG2
1 1/1/2001 ORG2
2 1/1/1999 ORG1
2 1/1/2000 ORG1
2 1/1/2001 ORG1
since the orgid 1 has changed the dept from org1 to org2 I do not want this to be appeared in the final count. Results should only include the orgid 2 since it didn't changed any dept.

I have 2 strings that I want to compare for example
string1 = 'ABC~AB/10/1234'
string2 = 'ABC~AB/10/1234~.....'
There could be anything after the 2nd ~ in string 2 is there a easy way of trimming string2 to the first 14 Characters? Or do I have to find the 2nd instance of ~ and then remove everything after (and including) that?

I have two databases.
one is "ora" it is a 8i version
2nd is "orcl" it is a 11g version
"Oracle" is the my local database. i wrote following program for comparing the row by row data in both the tables.
Q)Is it BEST practice? If not let me know the best practice to compare data in tables?
Q) If am not using the order by clause its giving me wrong output even though both the data tables has same data. WHY?
DECLARE
v_emptest1 EMP_TEST1%ROWTYPE;
v_emptest2 EMP_TEST1@ora%ROWTYPE;
v_suc_flg NUMBER := 0;
v_cnt1 NUMBER:=0;

How to select the transactions out of the database that occurred within 70 seconds of each other. The toll_date field is a TIMESTAMP field.
Problem is, I seem to only get transactions that occurred within 70 minutes of each other. On the timestamp field I break the math down into the seconds in a day and I add 70. I then subtract that value and add that value to the timestamp and I should get anything between those values right?
SELECT Acct_ID, Ln, Tag_Rd, COUNT(*)
FROM (
SELECT T1.Account_ID Acct_ID, T1.Tag_Read Tag_Rd, T1.Revenue_Date Rev_Date, T1.Toll_Date, T1.Lane_ID, T1.Plaza, T1.Lane Ln, T2.Toll_Date, T2.Plaza, T2.Lane
FROM Toll T1
JOIN Toll T2

Recently i have started working on PLSQL coding. I have a requirement. Either error or un-processed record count is 90% of to be processed records then the script has to fail. Currently I am having a situation where error count is 1 and total to be processed is also 1.
in the below
V_ERR is error count
V_UPS is un processed count
V_PROCESSED_COUNT is total to be processed.
I am expecting PASS result but it is giving FAIL.
DECLARE
V_ERR NUMBER:=0;
V_UPS NUMBER:=0;
V_PROCESSED_COUNT NUMBER:=0;
NIN NUMBER;
BEGIN
V_PROCESSED_COUNT:=1;

As part of our project, we need to perform table comparisons in two different databases. I am currently looking for various options to accomplish this.
One of them is doing minus operation between these two tables. Also, i have looked at the data compare option in toad utility.

Managed to confuse myself significantly. I essentially want to write a query to determine when two counts are the same using a subquery.
Eg:
R(x,y)
Select count(x)
from R
group by x;
Then I want to run another query to determine which x's have the same count value and output these corresponding x's.

I have a SQL query which joins several large tables (so indexes matter here) from Oracle database. In the where condition I use IS NULL with one of the date field values. Query takes 40 sec to run and if I comment this one line...it takes 1 sec to run. This date field is an index on the table and I learn that --
1. IS NOT NULL in where clause uses an index
2. IS NULL in where clause does not use an index
Is there any work around to make the query faster...other than changing all the NULL date values in the table to some string. In other words can I force it to use the index.

SF at oracle.com/technetwork/issue-archive/o53plsql-083350.html states that you can compare two database tables (of the same structure) by defining a nested table type (using %ROWTYPE) and two NT variables of that type, and loading the contents of each table into its respective NT variable, before comparing them using the = operator. Having read the Oracle documentation which states that you can only compare NTs for equality if they don't contain record types, I was surprised to read this, but figured I would try it because I must be misunderstanding SF, but it didn't work.
SCOTT@ORCL> create table empcopy3 as select * from emp;
Table created.
declare
type emp_ntt is table of emp%rowtype;
emp_nt1 emp_ntt;
[Code]....
But SF goes on to say he timed the execution of his NT equality method, comparing it with a SQL-only equivalent, and so I must be missing something. My understanding is that using %ROWTYPE declares a record type.

I have to compare a string entered in a form with a series of English strings in back-end PL/SQL( using LIKE operator )
But it so happens, the string entered in the form is specific to the language used in the country. for ex. in Dutch, it is entered in Dutch language.
So on comparing, it fails as the PL/SQL compares it with English Strings.

the problem is: 2 tables - one with 2 million records, and the other with 8000 records.
i need to compare for each record in a table if there's a similar string on the other table.
i've created a procedure that does the following:
opens the first cursor (select col1,col2,col3,col4... from table 1)
loop
opens second cursor (select col1 from table 2)
loop
if utl_match(col1, table2.col1) > 80 then
insert col1,col2,col3,col4... into tableX
end if
close second cursor
close first cursor
the thing is that this procedure takes forever to end...about 8 days.
is it because im using the utl_match function? is there a way to speed this up?

I'm using oracle 10g.I have a table with 4 columns
main_group-----id--------start_date------------end_date
M1-------------1---------07FEB11---------------10FEB11
M1-------------2---------09FEB11---------------11FEB11
M1-------------3---------10FEB11---------------12FEB11
M1-------------4---------13FEB11---------------16FEB11
M2-------------5---------18FEB11---------------21FEB11
M2-------------6---------19FEB11---------------24FEB11
M2-------------7---------26FEB11---------------27FEB11
i need to group the id's which are having overlapping dates and the output should be
main_group-----id--------start_date------------end_date
M1-------------1---------07FEB11---------------10FEB11------G1
M1-------------2---------09FEB11---------------11FEB11------G1
M1-------------3---------10FEB11---------------12FEB11------G1
M1-------------4---------13FEB11---------------16FEB11------G2
M2-------------5---------18FEB11---------------21FEB11------G3
M2-------------6---------19FEB11---------------24FEB11------G3
M2-------------7---------26FEB11---------------27FEB11------G4
I can give you the logic first i'll sort the start_date(already sorted in given example), then i'll compare the 2'nd id start date with 1'st id end date if it is less than the 1'st id end date, which means overlapping is there, then i'll group those 2 id's in to same group if not group them into 2 different groups.

I'm trying to work out how to take a table like this:
IDDate
12502-Feb-07
12516-Mar-07
12523-May-07
12524-May-07
12525-May-07
33302-Jan-09
33303-Jan-09
33304-Jan-09
33317-Mar-09
And display the data like this:
IDPeriodPeriod StartPeriod End
125102-Feb-0702-Feb-07
125216-Mar-0716-Mar-07
125323-May-0725-May-07
333102-Jan-0904-Jan-09
333217-Mar-0917-Mar-09
As you can see, it's split the entries into date ranges. If there is a 'lone' date, the 'period start' and the 'period end' are the same date.

we have a two different databases at different locations and on different servers, like one in our company with SID='A' and remote database with SID='B', We have recently implemented new module in database 'A' by creating lots of tables, functions, indexes, sequences, synonyms etc and now we need to install this on 'B' but the problem is we have not documented which tables we created, first we need to create a DB link between these two and then we need a tool to compare what are all the tables that we need to create in database 'B' , is there a tool for doing all this.

I have two schemas with 149 tables in each schema, what I need to do is to prove that the content(data) between the two schemas is identical. I know that all the table names between the two schemas are the same, just need to prove that there is no difference in data.
So the query needs to prove that Schema A content = Schema B content
I know I cant do a simple select from Schema A.tab1 minus select Schema B.tab1 but since there are 159 tables, I am not sure if this is an efficient way of doing it.

Oracle v11.1 Standard edition. I am trying to use TRIM function around the columns which are used for outer join and it's not working. However, if I use ANSI syntax, it works. Please check the SQL below.Is there any way, I can use old syntax and TRIM and get the outer join to work?I know, I can fix/trim the data in the tables, but for some reason (need to keep the data exactly same as we received it), that is not possible here.
