Deleting all tables in a schema

I am trying to delete all tables in a given schema. Any ideas how to do this via t-sql appreciated.
tia,
edm2

If the tables are not dependent one of the other, then simple query like this:
DECLARE @sql NVARCHAR(max)
SELECT @sql = stuff((
SELECT ', ' + quotename(table_schema) + '.' + quotename(table_name)
FROM INFORMATION_SCHEMA.Tables
WHERE table_schema = 'dbo'AND TABLE_TYPE = 'BASE TABLE'
ORDER BY table_name
FOR XML path('')
), 1, 2, '')
SET @sql = 'DROP TABLE ' + @sql
PRINT @sql
BEGIN TRANSACTION
EXECUTE (@SQL)
ROLLBACK TRANSACTION
If they are related, then the script will be much more complex as you need to drop tables in the right order.

Edited by: user8105261 on Nov 25, 2009 11:06 PMA typical way to reset a schema (e.g. to recreate a schema on the test database) is totally different.
1) Drop the user
2) recreate the user including table scripts from
2a) your version control system
2b) from a export dumpfile using the "nodata" option while importing

Can we export DATA from all tables in a schema?

Hi,
I have a question; Can we export all the DATA from all the tables present in the schema to any source (eigther CSV, TXT, DAt, etc..)?
Or
Can I have a PL/SQL procedure to display DATA from all Tables in a schema?
With Best Regards,

Hi,
This is pretty much what you need.
DECLARE
V_COUNT NUMBER;
v_sql varchar2(1000);
IN_OWNER_NAME VARCHAR2(100) := 'AP' ; -- SCHEMA NAME
TYPE T_COL_NAME is table of varchar2(1000) index by binary_integer;
v_col_tbl t_col_name;
BEGIN
FOR i in
(SELECT object_name
FROM dba_objects
     WHERE owner = IN_OWNER_NAME
     AND object_type ='TABLE'
and rownum < 2)
LOOP
v_sql := 'SELECT COUNT(*) FROM ' || i.object_name ;
EXECUTE IMMEDIATE v_sql INTO V_COUNT;
if v_count > 0 then
v_sql := 'SELECT * FROM ' || i.object_name ;
select column_name
bulk collect
into v_col_tbl
from DBA_TAB_COLUMNS
WHERE TABLE_NAME = I.OBJECT_NAME
AND OWNER = IN_OWNER_NAME;
-- start selecting the column and exporting using the column names selected.
end if;
if v_col_tbl.count > 0 then
for i in v_col_tbl.first .. v_col_tbl.last
loop
DBMS_OUTPUT.PUT_lINE(v_col_tbl(i));
end loop;
end if;
DBMS_OUTPUT.PUT_lINE( i.object_name || '-' || v_count);

SQL azure database size not dropping down after deleting all table

Dear all,
I have a simple database on Azure for which I have deleted all table data. The size of the database is still showing 5Mb of data and I am charge for that. I have heard that this may happen from cluster index getting fragmented.
I have run a querry I found on internet on all my table index to show percentage of fragmentation and all report 0%.
DBA is not so my job but what could it be or how can I reduce that size ?
ON premise I would use COMPACT DB but not available in azure like some others DB action
Thnaks for tips
regards

user created objects/data are not the only ones stored in your database. you got system objects and metadata as Mike mentions above.
are you trying to skip being charged if you're not storing data? looking at the pricing table, you'll still get charged the $4.995 for the 0-100MB database size range.

Need to grant DML privileges to all tables in few schemas

Hi,
I need to grant DML privileges to all tables in few schemas to a role. How can I achieve that?
I thought it's below syntax but it doesn't work. Please advice.
grant ALL ON ALL TABLES IN SCHEMA <Schema_name> TO <role_name>;Thanks,

There is no single command to grant privileges at that level. There are either ANY privileges or privileges on an object.
You can write a bit of code to generate and execute what you want, but you would have to rerun it if any new tables were created.

Grant select on all table of a schema to role

Hi , is it possible to grant select on all table on a schema to a role?

To grant SELECT on all tables of the current schema to particular role or user:
SELECT 'GRANT SELECT ON '||TABLE_NAME||' TO READ_ONLY_ROLE;' COMMAND
FROM (
SELECT TABLE_NAME
FROM ALL_TABLES
WHERE OWNER = (SELECT USER FROM DUAL)
Then copy and execute the result commands, eg:
GRANT SELECT ON DEPT TO READ_ONLY_ROLE;
GRANT SELECT ON EMP TO READ_ONLY_ROLE;
GRANT SELECT ON DEMO_USERS TO READ_ONLY_ROLE;
GRANT SELECT ON DEMO_CUSTOMERS TO READ_ONLY_ROLE;
GRANT SELECT ON DEMO_ORDERS TO READ_ONLY_ROLE;

we needed for our data conversion project..I don't know how you'll use the number of columns in all a schema for data conversion. Some columns are duplicated (e.g. PK/FK), should they really count for two ?
A data conversion means you should actually know what are the columns used for, not how many they are.
one more question that count include hidden columns
what is hidden column used for ? I can not see those columns in actual table.See here an example :

Hi,
You can create a script by yourself by executing the script mentioned below:
Connect as sys or system....
SQL> spool test.sql
SQL> select 'select count(*) from '||owner||'.'||table_name||';' from dba_tables;
SQL> spool off;
Hope this helps.

What privilege is needed to browse all tables in a schema

I used SQLPlus to login to DB. When I clicked "table" in the left side window, no tables is shown. What privilege is needed to browse all tables in a schema?
Thanks.

SQL*Plus is a command-line interface. There is no side window to click on. Perhaps you're talking about SQL Programmer? Or are you talking about some other tool?
What user are you logging in as? What user owns the objects? Do you just want to see that the tables exist? Or do you want to be able to see the data as well?

How to delete all TABLEs in Schema SYS which are created since 09:15?

Unfortunately a script created lots of tables in the wrong Tablespace (=SYSTEM) and Schema (=SYS).
How can I delete (in one DDL command) all TABLES which are created inTablespace=SYSTEM and SCHEMA=SYS
during the last 3 hours resp. since 09:15 of 25th Sep 2011 ?
Alternatively: How can I move these TABLEs to another Schema (e.g. ATEST) and Tablespace (USERS)?
Is this possible with Oracle XE or only with Oracle Enterprise?

PeterYou can query dba_objects and join it with dba_tables where tablespace_name='SYSTEM' , then drop the tables result of the query; the idea is to use the following query;
SQL> select OWNER, OBJECT_NAME from dba_objects where OBJECT_TYPE='TABLE' and OWNER = 'SYS' and CREATED >= sysdate - 3 / 24;Please consider marking your questions as answered, when it is the case;

Monitor all tables of a schema

Hi All,
I would like to monitor all the tables under a schema, hoping to have an alert (in email) if there is decrease in rows of any table owned by the schema (delete rows).
My db version is 11.1.0.6
Please share your suggestions on how it can be done, also if possible with some good examples
Thanks,

How to drop all tables in perticular schema??

Hi,
I am new in oracle.
I want to drop all tables in one perticular schema,
Please tell me solution.
PratHamesh

If your few of your tables have referential intigrity constraints and trying to drop master table whithout droping child table first, oracle will produce an error.
Better option would be to drop the entire schema and then create a new schema with the same name.
on sql plus.
set long size 20000
select dbms_metadata.get_ddl('USER','USERNAME') from dual;
--then save the above output to create the user later.
drop username cascade
use the above saved script to create the user again.
