SQL & PL/SQL :: Migrate Data From One Schema To Another
Jan 10, 2012
I have a requirement wherein I have to migrate the data from one schema(source) to another(target).The source and target schema contains 50 tables each.For testing purpose two table are shown below
I have an 11gR2 data base with Local Extent Management and Manual Segment Management. Can Data Guard be used to replicate this instance into ASM storage? [I have multiple long fields (BLOBs and CLOBs) in various tables.]
Connected to: Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit Production With the Partitioning, OLAP, Data Mining and Real Application Testing options Master table "MVANMANNEKES"."SYS_IMPORT_SCHEMA_01" successfully loaded/unloaded Starting "MVANMANNEKES"."SYS_IMPORT_SCHEMA_01": mvanmannekes/******** schemas=cmsstagingb remap_tablespace=cmsliveb_data:cmslivea_data
I need to migrate data from Mysql database to Oracle11g database.
a) is there any method available to import the all the sqls like table script,constraint scripts,data(insert ) script from Mysql.so that we can apply the sql directly to the oracle schema after making necessary changes(like datatype).
b) Is there any free tool available for the migration.
Table Name PURCHASE exists in all above three schema with different data(according to date)
Like User09 ----> purchase ---- data date Jan09 to Dec09 User10 ----> purchase ---- data date Jan10 to Dec10 User11 ----> purchase ---- data date Jan11 to Dec11
I want to select * from purchase, from above all three user with select statement.I can select data one by one with union all
select * from user09.pruchase Union all select * from user10.pruchase Union all select * from user11.pruchase
after creating this query I add another User User12 and that User has same purchase table so I will have to add one another line IN Union all Query. when I see this query. It gives me the all owner name of User09,User10,User11......
SELECT * FROM ALL_ALL_TABLES WHERE OWNER LIKE 'USER%' and table_name ='PURCHASE'
I have two same DB schema (same structure, same data) and I need to provide update in one of them when data in the other one is updated. It is singe direction only (we change data in DB Schema A and synchronize data in the DB Schema B; there is not opposite direction). Only small portion of data (compared to the size of DB Schema) might be changed or added this way.
I am working on Oracle 10g. I want to drop a schema and I want to re use the space in data files to other schema.
If I drop the user by "DROP USER USERNAME CASCADE" , tables in that schema are purged by default or do I have to explicitly drop the tables , purge the re cycle bin and then drop the schema?
I'm trying to figure out how to import data from another schema for an oracle SQL project in an MIS Course.Each student/schema created the following tables STUDENT, FACULTY, COURSE, IS_QUALIFIED, SECTION, IS_REGISTERED. Each student was supposed to make up names and ID numbers for 20 different students, then use real university faculty, courses, and sections to populate the respective tables.
I need to import data from all of another student's tables, without duplicating any courses, faculty, etc I already have in my tables.
The other student already granted acess to her tables, so now I'm just having trouble with the insert statement. This is what I have so far for the first table.
INSERT INTO myschema.STUDENT SELECT * FROM otherschema.STUDENT
I know i need to add a "WHERE" statement to successfully copy the other persons data into mine, without duplicating any results. This is the last part of this project and I'm having trouble finding the answer anywhere.
I am trying to move data from one schema in database A to another schema in database B and only move data not others (procedure, view, function). What is the best way to do it? I am thinking database link then insert into select from database link. Is there a better way?
I need to insert data from one schema table to other schema's table in same database.The thing is columns are not equal.so when I am trying to use insert statement it is throwing error as not enough values. The situation is explained clearly below.The insert stmt is implemented in second schema whose table name is b.
Table created. SQL> ALTER TABLE B ADD 2 CONSTRAINT B_PK1 3 PRIMARY KEY 4 (ID);
Table altered. SQL> create sequence b_seg start with 1;
Sequence created. SQL> insert into b select b_seg.nextval,lexcom.a.* from lexcom.a,dual; insert into b select b_seg.nextval,lexcom.a.* from lexcom.a,dual * ERROR at line 1: ORA-00947: not enough values
So,for table b in ID column sequence needed to be inserted and other columns need to be taken from table a.I can understand the error is because two tables are not having equal columns.So,the insert stmt is throwing error.
I can manually write by taking columns from a and b and write insert stmt as follows,but this is tedious process.
SQL> insert into b(ID,Name,rollno,address)select b_seg.nextval,lexcom.a.Name,lex com.a.rollno,lexcom.a.address from lexcom.a,dual;
3 rows created.
But this is time taking and I had tables which has many columns to be inserted.So is there any other way to solve it and implement insert stmt.
This message for my clarification,we have two schemas MAD_LIVE and MAD_TEST we want to take data from MAD_LIVE to MAD_TEST for particular period of time. way to import data from MAD_LIVE to MAD_TEST for particular period
My SCHEMA MAD_LIVE using from year 2010 till now,we want to take only 2012 data from MAD_LIVE and restore it in MAD_TEST.
I have created different scripts to monitor growth planning of the database my idea was generate a simple output file to a directory and create a report and send it as mail thru mail server. but the client requested me to create new schema and population all the stats i have collected into the tables in this schema .
How to pool all the stats from different databases into this new schema efficiently.
I want to take backup of selected data from tables of a schema (as huge data, that is not used, causing slow query performance) I planned to create a seprate backup schema and tablespace to store the data from these tables. Then write procedures that can move the data to and fro among table of those schema. And create partitioned index on those backup tables.
I am trying to access and modify data of a table of another schema which contains 80,000-90,000 records. My procedure is taking near about 30 mins to complete the operation. faster access and updation of table data.
Details: I have two schema: TEST and PROD I am running the below code from TEST Schema. /* CODE START HERE*/ DECLARE exc_bulk_errors EXCEPTION; PRAGMA EXCEPTION_INIT (exc_bulk_errors, -24381); v_block_count NUMBER := 1000;
[Code]....
The above code is taking near about 30mins to process.
I have also tried another approch: Creating a procedure in PROD schema to update COMPONENT_MASTER table and by calling the procedure from above code by passing component code.
/* PROCEDURE CALL FROM ABOCE CODE INTEST SCHEMA*/ PROD.PROCEDURE_TO_UPDATE(v_comp_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.
A single master schema where many developers are accessing. all share same password.
now i would like to trace all the changes made by each users. so i create a individual users for all and grant permission to access that schema.do i have a possibility of auditing the changes did by each user for that particular schema
We have an application with many separate databases (one per customer). Given they share the same business requirements (service hours, change mgmt etc), we're interested in potentially consolidating the separate DBs (which are relatively small) into separate schemas within a fewer no of databases to reduce the overhead.
Our issue is that the application is hard-coded to use a specific administrator and application connection user name. Changing this is unfortunately not an option.
Given this limitation, is there any possibility to map a generic user into a customer-specific schema based on the database service that they connect to? Each customer connects to different database services but may use the same user name. We considered using private synonyms but this seems to acheive the opposite (i.e. many different users could connect and map to a single users schema). One thing to point out is that where there is a single user name, it is acceptable for a single password to be used across the different customer DBs as they will be a single admin/user.
I would like to create a table in another schema(CBF) as already exist in my schema(TLC) without data but related indexes,synonyms and grants should be include.
How could I do this without using export import. I am using TOAD 9.0.1.
