Analyze all tables of one schema

hi,
the analyze table command is:
analyze table hr.employees compute statistics;
Now I want analyze all tables in the hr schema
how can I do it in a easy way,
thanks,
Zhiwei.

the only way to disable monitoring (globally) is to set statistics_level=basic.Exactly.

All columns of all table in one schema

Hi
All,
Oralce 10.2.0.3
I want to count all columns in all the table in one particular schema.
How can I do that?
which view i should use to count all cloumns of all tables in particular schema?
Thanks

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 :

Analyzing all tables in schema

Hello everyone,
I am used below command to analyze all tables in schema
EXEC DBMS_STATS.gather_schema_stats (ownname => 'CONTRACT', cascade =>true,estimate_percent => dbms_stats.auto_sample_size);when look at tables in dba_tables, for none of the tables LAST_ANALYZED date is changed to today. But when I did below
EXECUTE DBMS_STATS.GATHER_TABLE_STATS(ownname => 'CONTRACT', tabname => 'CONT_NAME', method_opt => 'FOR ALL COLUMNS', granularity => 'ALL', cascade => TRUE, degree => DBMS_STATS.DEFAULT_DEGREE);I am see LAST_ANALYZED changed to today in dba_tables.
If I need to change LAST_ANALYZED to all tables do I need to produce the above command for all tables? There are more then 700 tables for this application.

and
EXECUTE DBMS_STATS.GATHER_TABLE_STATS(ownname => 'CONTRACT', tabname => 'CONT_NAME', method_opt => 'FOR ALL COLUMNS', granularity => 'ALL', cascade => TRUE, degree => DBMS_STATS.DEFAULT_DEGREE);are fundamentally different, you cannot compare them. In gather_schema_stats, oracle used most defaults, decided none needed new stats collected, so it didn't do anything. In the second, you changed method_opt, granularity and degree etc from default values (as set in your db perhaps), so db went ahead and collected stats.
You need to look up manual and try to understand the default and non-default behavior for parameters and then make an educated decision. Changing stats randomly is not generally a great idea.

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.

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

How do I move a table from one schema to another schema on Oracle XE?

How do I move a table from one schema to another schema on Oracle XE?

Hi,
I tried to use the insert/select statement that you had given, it did not work.
The error is ORA-00913: too many values.
But finally what I did was, I went into the system schema where the table was and generated the DDL through the utilities and afterwards I imported them into the schema that I am currently working on. It solved the problem!
However I am still curious to know why the insert/select statement did not work? Do you know any site/tutorial which gives a real time example?
Thank you

How do I move a table from one schema to another schema?

Grant access to the table from the source schema to destination schema.
GRANT SELECT ON <TABLE_NAME> TO <DESTINATION SCHEMA>A simple way would be to use CREATE Table with select syntax (in destination schema)
CREATE TABLE <TABLE_NAME> AS SELECT * FROM <SOURCE SCHEMA>.<TABLE_NAME><li>However, you would be in trouble when the table has index,constraints and triggers.
So you can better of grab the DDL statement of the table(and any additional components) andd then create the table in the destination schema.You can use SQL developer, Toad or Apex's Object browser for this.
After the table is created, Insert the records using SELECT.
INSERT INTO <TABLE_NAME> SELECT * FROM <SOURCE SCHEMA>.<TABLE_NAME>This question is discussed in great detail in this AskTom thread

Question about import all tables except one

I have exported all tables for a user. While importing I want to import all tables except one table whose name I know. How do I do this? Example: If I have tables: Employee, address, salary that I have exported. While importing I want to import only Employee and address. How do I do this. The database I have exported contains over 20 tables.

I don't think it is possible at all, you just need to explicitly specify all the tables.
If you really don't want to include the single table, then you can import all the tables and drop the desired one.

How Can I obtain the tables of one schema and the record size???

How Can I obtain the tables of one schema and the record size???
Example:
TableName Record Size

This is not an OWB question, but you can obtain bda-type information on tables by using the system view dba_tables.

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.
