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?
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.
i 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.
I am trying to describe all the tables in a database.We use desc or describe tablename; to describe a table, but what is the command to describe all the tables in a database (i don't need the system tables)
Once i log into sqlplus as a say ABC (SID or HostString) as a user then if i do a desc table name i get column name, data type and null not null etc but i i need that for all the tables in that ABC database..
I have installed oracle 10g software and created Database on RHEL 4. when i run the run.sql its successively done but im not getting tables. whats the prob.
“AUDIT DELETE ANY TABLE BY <username> BY ACCESS” or “AUDIT UPDATE ANY TABLE<username> BY ACCESS”
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
I have 3 tables in the Oracle database( emp, employee, emp1) which has following record values in it.
empidenamejob 7369, 'SMITH', 'CLERK'
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 have seen the below blog abut database driven menu in java. uRL..... look into the below tables and its data below.I have concerned inserting data in the tables and particularly about
ROLE_DETAILS,ROLE_MASTER and EM_MENUMAS data. select level lvl, ID, NAME, lpad(' ', level * 14, ' ') || NAME menu, parent_NAME,nodetype, page_name from em_menumas [code].....
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.
declare i INTEGER:=0; flag boolean:= FALSE; vcInsert:='INSERT INTO CRM_DELT_IMPORT ('; if length(i_vcColumn1) > 0 then flag:=TRUE;
[code]....
i am fetching data from excel all data is of general type, here i am passing value is VTDATE varchar2(100) but actual database column filed is DATE , How can i pass '13-06-13 05:54:33' to database table.
if i put this condition vcInsert:=vcInsert|| ','||''''||i_ldata(i).to_char(VTDATE,'DD-MM-RR HH12:MI:SS') i get the error to_char must be declare.
if i remove this line
i am getting this error ORA-01843: not a valid month
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.
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?
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?
In our schema we have corresponding audit tables for most of the production tables
Ex Table name Audit Table EMP EMP_AU DEPT DEPT_AU
Audit tables will have all the columns of production table along with audit columns AUDIT_DATE , AUDIT_OPERATION There are few production tables which are not having audit tables.I need to write a script to identify
1) Production tables where corresponding audit table is missing
2) Where there is column difference (In case any column missing in audit table) between Production table and Audit table
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.
I have the Table name Location and synonym named Location in my DB. I am trying to create the proc where I am tryting to call the table. But its not working.
Example: CREATE PROCEDURE TESTPROC AS BEGIN DBMS_OUTPUT.PUT_LINE('testing'); select count(*) from LOCATION; END;
Compile error: Error(5,22): PL/SQL: ORA-00942: table or view does not exist
