SELECT INTO using Oracle
I have one table in my oracle database. I want to create one table with another name, but containing same data. How to achieve this ?
Use this query to create the new table with the values from existing table
CREATE TABLE New_Table_name AS SELECT * FROM Existing_table_Name;
Now you can get all the values from existing table into newly created table.

Creating a table from a query using a different tablespace (Oracle SQL)
(1 answer)

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";

Oracle trigger after insert or delete

I have a table whose name is TestTable.
Create Table TestTable(ID number,Name nvarchar2(200))
I want to write a trigger. It's a statement level trigger. My question is:
How to get new and old value of column in statement level trigger in oracle?
I can't use a row level trigger because I need to select row count from TestTable in trigger.
As comments said you can't have access to :new and :old on statement level. How can you define row values if trigger that see whole statement?
Please use compound trigger (Documentation and Example). There you can write section that is statement level and another one for each row. Count you'll get in statement level and access to :old and :new you'll have on for each row section

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 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

displaying Oracle table's column names

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 ;)
