I need to run 5 scripts to create 5 tables, seems each table needs to take 2 hrs, so I plan to put all 5 commands together
so i would have tables.sql to contain the following
do you know how to add time in beginning and end , so I can figure it out how long does this take to create 5 tables, use spool too?
create table a as select * from ........ ;
create table b as select * from ........ ;
create table c as select * from ........ ;
create table d as select * from ........ ;
create table e as select * from ........ ;
I have created 2 different databases and each have their own schema user for eg we have database ALIVE with user allive and the other database RLIVE with user rllive , actually we have implemented new module in ALIVE database and in the process we created many tables , synonyms , index and other objects now we want to list out all the tables ,sequences as scripts which are not present in RLIVE and create them in RLIVE as new objects.
We have an application is must be connected to our database for specific requirements in our company but this application has a very bug thing as we must write the super DB password "Like HR password as example" clear in some files and these files must be shared so developers can use the HR password to do any action !!! I know that this application is a problem but we have to install
I can do this by creating trigger on each table will restrict DML. As example: if the operating system user is XXX, the trigger restrict the action. But not logic at all to create more than 1000 triggers on schema (This will impact badly on DB performance).
So, i need to create one trigger to fire before doing any DML on all schema tables. As example: If "MMM" the administrator operating system user trying to do insert action, he can do the action. BUT If "DEV" the developer operating system user trying to do insert action, the trigger must fire here to restrict this action.
Be noted also, i need this trigger not depend on any specific tool like Toad as any user can simply rename the exe file for toad then he can pass the trigger. At least, trigger must depend on (Operating system user & Action_type)
Region Code,Name,Surname,ID_Number 1,John,Doe,67 1,Sarah,Jason,45 2,Bob,Marley,69 3,Steven,Johnson,900 2,Harry,Potter,890 3,Sandy,Bay,567 3,Else,Taylor,789 .....
I have about over 100 region codes and each region would like to get their own data. I can manually do the extraction and create a new table for every region, but it's going to take too long.
Suppose two users (CONNECT and RESOURCE roles) A and B who work on the same project. How can B create synonyms of all tables of A without asking admin to do that? Of course, we assume that these users have the CREATE SYNONYM privilege. My problem is that B does not have access to user_tables of A, so he cannot obtain the list of A's tables to create synonyms.
is it possible to create tables using variables in pl/sql such as the following example which is actually in php. i would like to create a table dynamically.
$create_samp_table = CREATE TABLE $MCSCHEMA.".$samp_id." AS SELECT * FROM $MCSCHEMA.".$samp_src_table." WHERE ROWNUM = 0
I have 2 tables that doesn't have primary keys. These 2 tables have same number of rows. I want to create a new table from getting some columns from table1 and some columns from table 2. I want to combine first row from table1 and first row from table2.
Below is example
TABLE1
ACOL1 ACOL2 ACOL3 A1 A2 A3 B1 B2 B3 C1 C2 C3
TABLE2
BCOL1 BCOL2 BCOL3 11 12 13 21 22 23 31 32 33
COMBINED_TABLE
ACOL1 BCOL2 BCOL3 A1 12 13 B1 22 23 C1 32 33
I tried below query but no luck. It gives below error:
Query : create table COMBINED_TABLE AS select a.ACOL1, b.BCOL2, b.BCOL3 from (select ACOL1,rownum from TABLE1) a, (select BCOL2, BCOL3, rownum from TABLE2) b WHERE a.rownum = b.rownum
Error : ORA-01747:"invalid user.table.column, table.column, or column specification"
I'm trying to do is create 4 simple tables. This is my first project using SQL so I'm totally new to it, not just SQL itself but database design/management, including foreign/primary key concepts. I think that's why the errors are being generated due to a duplication of foreign key names (perhaps?) but I really don't where I'm going wrong with the design structure in terms of the FK's and the relationships.
Added the error report in the attachment.
Create Table Hotel (Hotel_No Char(4 Byte) Not Null, H_Name VarChar2(20 Byte) Not Null, H_Address VarChar2(30 Byte), Constraint Hotel_PK Primary Key (Hotel_No));
Here the SUB1 and SUB2 are "tables" and are similar in their structure. The "Main_Table" will be update dynamically and the no of rows in this table will vary.
Now my question , i need to create a view which will have all the rows from these tables ,in the current case it is something like
create or replace view sample as select * from SUB1 union all select * from SUB2
How can this be achived. I tried as shown below:
spool file_to_exe.sql select 'select * from ' || AA ||' union all ' from Main_table; spool off
i will end up in a union all "extra" , if i do like this.
I'm stuck on the CREATE VIEW part and the SELECT statement to get the output of the CREATE VIEW. We were instructed not to use AND and simply use JOIN on this exercise.

I would like to create a trigger on a table which populates a log table. In addition to using the table where the trigger will exist, I would like to populate a couple more fields in the log table with with data from 2 other tables.
e.g.
NAME_TABLE -reg_id -name
ADDRESS_TABLE *trigger to be fired when a new record is created here. -reg_id -srv_id
PROCESS_TABLE -srv_id -start_time -end_time
This is what I would like the logging table to look like:
I want to create a block of code that would search in all tables in a schema for a column_name where its data_length is like 4000 let's say. This data_length is actually dedicated for a comment column. If found, all not null column with like 4000 data_length will be changed by string "Comment has been removed". I have the following script below but it seemed lacking.
begin for rec in (select table_name, column_name from user_tab_columns where column_name like ?data_length? = 4000 order by 1,2) loop begin execute immediate 'update '||rec.table_name||' set '||rec.column_name||' = ''Comment has been removed'' where '||rec.column_name||' is not null'; commit; [code]........
Create small functional indexes for special cases in very large tables.
When there is a column having one values in 99% records and another values that have to be search for, it is possible to create an index using null value. Index will be small and the rebuild fast.
Example
create index vh_tst_decode_ind_if1 on vh_tst_decode_ind (decode(S,'I','I',null),style)
It is possible to do index more selective when the key is updated and there are many records to create more levels in b-tree.
create index vh_tst_decode_ind_if3 on vh_tst_decode_ind (decode(S,'I','I',null), decode(S,'I',style,null) )
To access the record can by like:
SQL> select --+ index(vh_tst_decode_ind_if3) 2 style ,count(*) 3 from vh_tst_decode_ind 4 where 5 decode(S,'I','I',null)='I' 6 group by style 7 ;
problem on oracle 11gR2 where i have to import data from a source database to an existing table without truncate or drop the target table in the target database.
we have found something called table_exist_action=append in impdp.
I have to cleanup data from our tables (Production Environment) that contain millions of rows. The question is apart from the solution of the partitioned tables what alternative recommended solution suggests Oracle?
To delete these tables by using a cursor PL/SQL block or to import all the database and in the tables that we want to remove the old rows to use the QUERY option of the data pump utility.
I have used both ways and i have to admit that datapump solution is much much faster than the deletion that suffers from I/O disk.The question again is which method from these two is more reliable and less risky for the health of the database.
I came across an implementation where data from DB2 tables are moved to Oracle tables, for BI solutioning, using some oracle procedures called from MS SQL DTS packages which are scheduled jobs.Just being curious, can this be done using OWB or ODI rather than the above detour. I suppose there are some changes being done in those procedures before the data is being loaded into Oracle tables, can't this be done using OWB/ODI? Can it be scheduled too as jobs using OWB/ODI?
In our schema we have corresponding audit tables for most of the production tables
Ex Table name Audit Table EMP EMP_AU DEPT DEPT_AU
Audit tables will have all the columns of production table along with audit columns AUDIT_DATE , AUDIT_OPERATION There are few production tables which are not having audit tables.I need to write a script to identify
1) Production tables where corresponding audit table is missing
2) Where there is column difference (In case any column missing in audit table) between Production table and Audit table
I need to create PROCEDURE to create user in oracle

ORA-06502...I have database on oracle 9i on Solaris 9. I create a generate procedure that create dynamic procedure through DBMS_SQL. On this database I got the ORA-06502 error. When I tried to run the same procedure on the same database on oracle 8i on NT this work fine.
Also I've got tables tab2 and tab3 with indicatorid column in each table.
My need is to prevent inserting values into indicatorid column in tables tab2 and tab3 which are absent in id column in table tab1.
For example, at this moment id column in table tab1 has two values, 1 and 2. I can insert value 3 into indicatorid column in tables tab2 and tab3. I need to prevent from inserting value 3 into indicatorid column in tables tab2 and tab3 while it is absent in id column of tab1 table.
I have the Table name Location and synonym named Location in my DB. I am trying to create the proc where I am tryting to call the table. But its not working.
Example: CREATE PROCEDURE TESTPROC AS BEGIN DBMS_OUTPUT.PUT_LINE('testing'); select count(*) from LOCATION; END;
Compile error: Error(5,22): PL/SQL: ORA-00942: table or view does not exist
can we link a table that contains a foreign key with a sequence table? i have a table that has a sequence bookid and i want to link this table to another table that contains a foreign key of bookid.can i link this two table and how?
