There are two tables like I posted below.I want a SQL query which selects all the rows from TABLE A which are not present in TABLE B. Also the select statement should pick all those rows which has updated value of COL_A2 in TABLE A.
TABLE A
COL_A1COL_A2
AAAMOBILE
BBBTABLET
CCCDESKTOP
DDDUNKNOWN
TABLE B
COL_B1COL_B2
AAAMOBILE
BBBUNKNOWN
CCCDESKTOP
The select statement should return following rows from TABLE A
COL_A1COL_A2
BBBTABLET

We were trying to insert approx 76 million records worth of approx 4 GB in a table when the insert operation failed with the archive log error.
The database was hanged, we re-started the database and currently there are no records in the table but when we are firing a select
select count(*)
from table
It's taking approx 2 mins to come out with the result.
We checked and found that there are no locks on the table currently.
what do we need to do to get the performance back

I have connected to the database from two sessions
Box 1 : i have executed a procedure.it took few seconds to get executed
Box 2 : I have executed a block of procedure.It is taking 1 min 40 secs to get executed.
why it is taking much time from Box2(for executing a block from procedure) , as the same code executed successfully in a procedure from Box 1.

I have to build a select query but its where conditions will be retrieved from a table. I was told that the execute immediate command can handle it.
lets say i have this:
string_var:= 'select field1, field2, field3
from mytable
where' ' || i.condition_selection || ';'
If the above select resuls in a single row, i could do this:
EXECUTE IMMEDIATE string_var INTO var_field1, var_field2, var_field3;
In my case the select will return multiple rows. How do I proceed ?

have an automated process which runs on an Oracle 8i database server as user abc. This process creates views/tables in other schemas, on the same database server, which point to objects owned by the abc user.
The issue I'm getting is that when I try to execute GRANT SELECT ON xyz.view123 TO PUBLIC as the abc user, I get an insufficient privileges.I should add that the abc user created the xyz.view123 table/view.
What grants/priviliges or whatever do I have to do to the abc schema?

I have a question regarding the optimal way to code a dynamic SELECT INTO statement. Below are the 2 posiibilities I know of:
1. Dynamically executing the SELECT statement and making use of the INTO clause of the EXECUTE IMMEDIATE
statement
CREATE OR REPLACE FUNCTION get_num_of_employees (p_loc VARCHAR2, p_job VARCHAR2)
RETURN NUMBER
IS
v_query_str VARCHAR2(1000);
[code]...
2. Encapsulating the SELECT INTO statement in a block and dynamically exectuting the block
CREATE OR REPLACE FUNCTION get_num_of_employees (p_loc VARCHAR2, p_job VARCHAR2)
RETURN NUMBER
IS
v_query_str VARCHAR2(1000);
[code]...
which way would be preferred? I know the second method uses a bind variable for the INTO clause, but does the first one also use bind varialbes (no semi-colon)? Any differences in terms of efficiency or speed?

A block shouldn't have rows from multiple tables... Is that true? I read in one of the OTN thread (i don't exactly remember the thread name) that a block can have data from multiple tables. If it doesn't have, what's the table directory in block signifies?

While writing a procedure I went into this problem. Whenever I write Query : Select * from dba_pending_transactions It works fine.
But whenever I use same Select Query inside PL-SQL block it gives error Table or view not exist. Dba_pending_transactions is view.
SQL> declare
2 v_count number(2);
3 begin
4 execute immediate 'select count(*) from dba_ending_transactions' into v_count;
5 dbms_output.put_line(v_count);
6 end;
7 /
declare
*
ERROR at line 1:
ORA-00942: table or view does not exist
ORA-06512: at line 4
Same error I get when i use it inside a procedure.

I would like to know how to increase the result set of a 'Select' statement? I did a 'Select' that should have returned 36,000 rows and got only 5000 rows. What access level do I need to change this and what do I need to change? I am trying to do a migration of data from a delimited file to a table in Oracle. Yet, the data has to be filtered out prior to loading to the table?
SQLSELECT MIN(major_zipcode)
FROM TEMP WHERE MAJOR_CITIES IN (select distinct major_cities from temp);
