I have one table in a particular database and will have to create another table in a different database. I will have to join these two tables from two different DB's.
How should I go about doing this? Is this a good practice? or is it always better to use a single DB?
What are the disadvantages of joining two tables from two different DB's?
I had face the problem regarding to database structure changes..
I had a old database which contain multiple column for 1 empno. which contain multiple subjects and its total marks.
Now the new structure is like all subjects and total marks as a row.
Eg. OLD data Structure
EMPNO SUNBJECT_CODE TOTAL_MARKS
1111 S1 45
1111 S2 21
1111 S3 55
1111 S4 41
NEW DATA STRUCTURE
EMPNO SUB1 MARK1 SUB2 MARK2 SUB3 MARK3 SUB4 MARK4
1111 S1 45 S2 21 S3 55 S4 41
I have more than 1.5 lakhs records in my old data structure..
Is there any Possibilities direct from Sql or i have to do it manually in excel sheet?
The database system they have has around 5000 tables. The majority of these are not used (it is an off the shelf package). What I am trying to do is get a list of all tables in the database BUT only those that contain records (not the empty tables) and then copy this to an excel spreadsheet. We use a tool called aquadata to run sql enquiry statements on.

View 3 Replies View Relatedi work on oracle 8i with around 950 tables in my database. when i export or import it gives me the no of rows exported / imported from each table. is it possible to take a print out of the no of rows in each table through a single query .
select count(*) from each table takes a long time , since there are 950 tables.
we are looking to use oracle 11g as a log database using partitioned tables.
- The tables will have only a 3-5 columns of ~varchar(50) size
- We are looking at a volumn of ~33million rows (inserts) per day.
1) Will partitioned tables be able to handle this type of volume?
2) if yes, will a Composite Partitioning (using last modified datetime as range) then subparition with range be the best choice?
if this type of volume is too high for 11g, what are some of the alternative products we can use.
I've recieved a recent request wherein the requirement is to swap values between columns across multiple tables in a database.Following is a visual sample of what needs to be done.
Before Swaping:
Columns Values
TABLE1.IDENTIFIER MRN123
TABLE1.MEDICARENO CHI1234567
TABLE2.MRN MRN123
TABLE3.MRN MRN123
OTHERTABLE.MRN MRN123
After Swapping:
Columns Values
TABLE1.IDENTIFIER CHI1234567
TABLE1.MEDICARENO MRN123
TABLE2.MRN CHI1234567
TABLE3.MRN CHI1234567
OTHERTABLE.MRN CHI1234567

enable audit for delete and updates for given username/schema. I want to enable auditing on delete and update on my entire database.
Why? And have we tested it in our any of existing setup? I am thinking of “Trigger after delete” but again this logic gets struck at individual tables. It do not work simply once and all for complete database/all users/all schemas

View -1 Replies View RelatedI have 3 tables in the Oracle database( emp, employee, emp1) which has following record values in it.

I would like to list these 3 tables thru SQL/PLSQL, having the above record values combination. Also, the name of the columns could be different in all the tables i.e. name could be 'ename' in Emp table , and 'name' in Employee table. Is there way to do this in SQL or PLSQL ?

I am trying to attach lifecycle definitions to tables of Oracle EBS R12 database, using the "Refresh table list" option of ILM assitant.
Though its showing the refresh job running to completion, but its not displaying the list all of tables.
Tried it with narrowing the search for a single schema but no luck.
how to get the list of all tables or at least list of tables belonging to a schema in Oracle EBS R12.
I'm trying to export a relatively large database but it's a bit more complicated than that.For one schema I need a full export / import (data included).
For another 10 schemas I need them empty, with the exception of a table in some of them which needs to be exported / imported with all data inside.Is it possible to do this with datapump utility (impdp, expdp)?
Afterwards I will be running some scripts to populate the DB instance with critical data / metadata.
it's possible to retrieve the names of tables that contain similar information in an oracle database.

I have 780(12*65) csv files generated from 65 databases.Now I have to load this 780 csv files into 12 tables created in my database for some monitoring and reporting purpose.to call the sql loader I am plannig to create 780 lines like below.
sqlldr abc@tns/pwd control='E:htmlctlhtml_broken_jobs_rpt.ctl' log='E:htmlreportloghtml_broken_jobs_rpt.log'
sqlldr abc@tns/pwd control='E:htmlctlhtml_db_size_rpt.ctl' log='E:htmlreportloghtml_db_size_rpt.log'
sqlldr abc@tns/pwd control='E:htmlctlhtml_fragmentation_rpt.ctl' log='E:htmlreportloghtml_fragmentation_rpt.log'
sqlldr abc@tns/pwd control='E:htmlctlhtml_index_stats_rpt.ctl' log='E:htmlreportloghtml_index_stats_rpt.log'
sqlldr abc@tns/pwd control='E:htmlctlhtml_invalid_object_rpt.ctl' log='E:htmlreportloghtml_invalid_object_rpt.log'
sqlldr abc@tns/pwd control='E:htmlctlhtml_long_running_queries_rpt.ctl' log='E:htmlreportloghtml_long_running_queries_rpt.log'
we know creating 780 control files is the difficult task.So I have created only 12 control files. is there any mechanism to pass a varible (planning to declare it in the sqlldr line) to the infile clause like below in sql loader?
infile "E:htmlreportoutput&a_html_broken_jobs_rpt.csv"
here a is the variable name. it will change every 12 csv files once.
or
is there anyother way to achive this?

problem on oracle 11gR2 where i have to import data from a source database to an existing table without truncate or drop the target table in the target database.
we have found something called table_exist_action=append in impdp.
I have to cleanup data from our tables (Production Environment) that contain millions of rows. The question is apart from the solution of the partitioned tables what alternative recommended solution suggests Oracle?
To delete these tables by using a cursor PL/SQL block or to import all the database and in the tables that we want to remove the old rows to use the QUERY option of the data pump utility.
I have used both ways and i have to admit that datapump solution is much much faster than the deletion that suffers from I/O disk.The question again is which method from these two is more reliable and less risky for the health of the database.
I came across an implementation where data from DB2 tables are moved to Oracle tables, for BI solutioning, using some oracle procedures called from MS SQL DTS packages which are scheduled jobs.Just being curious, can this be done using OWB or ODI rather than the above detour. I suppose there are some changes being done in those procedures before the data is being loaded into Oracle tables, can't this be done using OWB/ODI? Can it be scheduled too as jobs using OWB/ODI?
View 1 Replies View RelatedIn our schema we have corresponding audit tables for most of the production tables

I've got table tab1 with sequence id column.
Also I've got tables tab2 and tab3 with indicatorid column in each table.
My need is to prevent inserting values into indicatorid column in tables tab2 and tab3 which are absent in id column in table tab1.
For example, at this moment id column in table tab1 has two values, 1 and 2. I can insert value 3 into indicatorid column in tables tab2 and tab3. I need to prevent from inserting value 3 into indicatorid column in tables tab2 and tab3 while it is absent in id column of tab1 table.
How do I perform it?
