How to export empty tables in oracle
(3 answers)
Closed 1 year ago.
Im using oracle 11g to export a database, but they seem to ignore empty tables
Is there any command that i can export all tables?
Use the parameter CONTENT=ALL. This is the default, but it sounds as if you have CONTENT=DATA_ONLY set.

How to copy data from one data base to another database table using script like procedure, cursor etc.
I am using oracle-sql developer.
Doing it using a script like procedure, cursor etc. is not the way to do it. Oracle offers Data Pump export and import utilities which are designed to move data around, so I'd suggest you to use them.

Creating a table from a query using a different tablespace (Oracle SQL)
(1 answer)
Closed 5 years ago.
I tried to simply create a table with the structure of another table to sync them contents later.
When is use "CREATE as SELECT", it just returns the error
ORA-00933 "SQL command not properly ended"
As mentioned in the link, the syntax should be OK.
https://www.techonthenet.com/oracle/tables/create_table2.php
Both tables should be stored in the same user scheme.
The only difference is the added user scheme and tablespace.
CREATE TABLE "MYUSER.TABLE_B"
as (SELECT * FROM "MYUSER.TABLE_A")
TABLESPACE "SANDBOX" ;
I don't have Oracle database with me now, but I am sure, you can use like this-
CREATE TABLE "MYUSER.TABLE_B"
TABLESPACE "SANDBOX"
AS
SELECT *
FROM "MYUSER.TABLE_A";

Automated Oracle Schema Migration Tool [closed]

Is it possible in Oracle to generate a bunch of ALTER TABLE statements based on existing table in schema plus CREATE TABLE statement with newer definition of that table?
Let's say I have a schema with some previous version of an application. I have an installation script for newest version of the application. The script creates all tables and sequences from scratch performing CREATE TABLE (and probably CREATE SEQUENCE) statements.
I'd like to update the schema to the newest version of the application without loosing any data (e.g. without performing DROP TABLE).
Is it possible with using of standard Oracle 11gR2 or third party components?
You can try CORT : www.cort.tech

It's free
You can create a procedure in PLSQL to:
create new table when it not exists in new DB
alter table when it exists, feeding it with ALL_TAB_COLUMNS

Is there a procedure I can run to search all tables to see to search a particular column? I need to update a particular string present in that column in all tables whereever applicable. There are too many tables to open each one and do a find on the value(s) I'm looking for.
This should help you find the tables which contain your columns:
SELECT TABLE_NAME
FROM USER_TAB_COLUMNS
WHERE COLUMN_NAME='your_column_name';
After that you can execute updates for each table that you have.
I didn't understand your question completely, so I hope this helps you ;)
