SQL & PL/SQL :: Comparing Schemas - Content (data) Identical
Jan 20, 2011
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.

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;
[code].......

adjusting a query. I have a table which looks like this:
CREATE TABLE PF.PF_ANOMALIES
(
ID VARCHAR2(10 BYTE) NOT NULL,
PLAN_ID VARCHAR2(10 BYTE),
CLIENT_ID VARCHAR2(10 BYTE),
SEDOL_CODE VARCHAR2(7 BYTE),
LTY_ID VARCHAR2(10 BYTE),
[Code]....
I have the following query that will return me the anomalies of client transactions (based on joining other tables for extra info too)
SELECT pc.client_id,
pc.client_name,
NVL(pa.sedol_code, 'N/A'),
DECODE(ps.stock_name, NULL,
DECODE(plt.lty_name, NULL, 'N/A', UPPER(plt.lty_name) || ' LEDGER - ' || pa.orig_price_ccy),
[Code]....
-- Get cash anomalies on top as these will have 'N/A' sedols I have another temp table that also gets populated with anomalies:
CREATE GLOBAL TEMPORARY TABLE PF.PF_ANOMALIES_TMP
(
ID VARCHAR2(10 BYTE) NOT NULL,
FVD_TYPE VARCHAR2(10 BYTE) NOT NULL,
CLIENT_ID VARCHAR2(10 BYTE),
SEDOL_CODE VARCHAR2(7 BYTE),
[Code]..
My problem is that I also want my query to return rows from this tmp table too.

I have a table:
Name
_____
Smith Street
Smith Street
John Street
Ed Street
Ed Street
Ed Street
and need to assign sequence numbers only when the record (Name) changes, e.g. :
Name Seq
_____ ____
Smith Street 1
Smith Street 1
John Street 2
Ed Street 3
Ed Street 3
Ed Street 3
I have experimented with row_number partition but then i just get the sequence returning to 1 when the name value changes.
If I grouped the records by Name I would like to have unique, sequential numbers: 1, 2, 3 but where there is the same name I would like the sequence to stop and the number to replicate?

We have a 2 database identical ( Say DB1 & DB2). In that, one of the database(DB2) base got corrupted. We cant recover back the database due to hard disk problem. So we did a new installation of database and patched to current level.
Now I want make DB2 up and running. So I though of generating a script from DB1 and run it in DB2 to restore back.

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.

V_CNT NUMBER := 0;

[code]....
but when i select the object of another schema, got output.

I'm trying to get the Create-Statements of all tables of several schemas:
SELECT DBMS_METADATA.GET_DDL('TABLE',u.table_name,'<schmema>')
FROM (SELECT TABLE_NAME, OWNER FROM SYS.ALL_TABLES WHERE owner='<schema>') u
Is there a way to create a loop to handle several schemas listed in a array, for example?

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?

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;

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.

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)

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.
