We have a UNIX box hosting an Oracle DB. We need to delete records on a daily basis from a table in this DB. We are setting up a scheduled job outside of Oracle that will run a script daily to do this.
Could you please help me create a .sh script file to do the same? I have the username/pwd for the DB.
The query is: DELETE FROM AUDIT_LOG WHERE EVENT_DATE <= SYSTIMESTAMP - 1;
In KORN shell you can do this as below:
#!/bin/ksh
`sqlplus "<schema_name>/<password>" << EOF
set feedback off
set heading off
DELETE FROM AUDIT_LOG WHERE EVENT_DATE <= SYSTIMESTAMP - 1;
exit;
EOF`

I have one script script.sql which I want to execute from command line using oracle and passing it two parameters, as shown below
sqlplus user/pass # script.sql my_parameter1_value my_parameter2_value
What should it be in script.sql in order to be able to run it with the parameter values?
The solution can be prepared looking at oracle blogs:
https://blogs.oracle.com/opal/sqlplus-101-substitution-variables#2_7
For the question above, the solution would be to create a script.sql like this:
DEFINE START_VALUE = &1;
DEFINE STOP_VALUE = &2;
SELECT * FROM my_table
WHERE
value BETWEN &&START_VALUE AND &&STOP_VALUE;
I wanted to run a script that would return all orders raised during the last seven days. Here's how...
the script
SELECT * FROM orders_detail WHERE order_date BETWEEN '&1' AND '&2';
EXIT;
the command
sqlplus ot/Orcl1234#xepdb1 #"/opt/oracle/oradata/Custom Scripts/orders_between_dates.sql" $(date +%d-%b-%Y -d '-7 days') $(date +%d-%b-%Y)
Hope that helps someone. Luck.
Is there a way to catch all schema + table name info in a single command through Hive in a similar way to
SELECT * FROM information_schema.tables
from the PostgreSQL world?
show databases and show tables combined in a loop [here an example] is an answer, but I'm looking for a more compact way to have the same result in a single command.
It's been long I have worked on Hive Queries but as far as I remember you can probably use
hive> desc formatted tableName;
or
hive> describe formatted tableName;
It will give you all the relevant information related to the Table like the Schema, Partition info, Table Type like Managed Table, etc
I am not sure If you are particularly looking for this ??
There is another way to query Hive Tables, is writing Hive Scripts which can be called from Hadoop Terminal rather than from Hive Terminal itself.
std]$ cat sample.hql or vi sample.hql
use dbName;
select * from tableName;
desc formatted tableName;
# this hql script can be called from outside the hive terminal
std]$ hive -f sample.hql
or, without even have to write script file you can probably query hive as
std]$ hive -e "use dbName; select * from emp;" > text.txt or >> to append
On the Database level, you can probably query as :
hive> use dbName;
hive> set hive.cli.print.current.db=true;
hive(dbName)> describe database dbName;
it will bring metadata from MySQL(metastore) about the Database.
Hi I am new to shell scripting and trying to insert data in a csv file which i generated to an oracle database table. my code is below
FilePath =/oracle/some path
Filename=test.csv
X='sqlplus -s username/password#dbname<< EOF
set heading off pages 0 feedback off
SELECT a.user_id,a.email_id FROM addresses a where
a.user_id in('ABCD','EFGH','IJKL','MNOP');
EXIT
EOF`
While read line
do
echo $line
sqlplus -s username/password#dbname<< EOF
insert into sometable (uid,email) values ($line);
commit;
exit
EOF
done<<
Can someone tell me what i amdoing wrong as data is not getting inserted.A sample working code will be deeply appreciated.
Hello i want to connect to following dbs in loop and execute statements on each:
conn support/support#sp0666to
conn support/support#sp0667to
conn support/support#sp0668to
Is there any way to do this in sqlplus?
Thank you for your answers in advance!
Create one script (doWork.sql) that contains the majority of what you want to do:
conn &1/&2#&3
select EMPLOYEE, AUTHORIZED, TIME, DAT, WORKSTATION
from EMPLOYEE
where status = 25;
In a separate script (goToWork.sql):
set lines 1500 pages 10000
set colsep ';'
set sqlprompt ''
set heading on
set headsep off
set newpage none column tm new_value file_time noprint
select to_char(sysdate, 'DDMMYYYY_HH24.MI') tm from dual;
accept user
accept pass
spool C:\Users\NANCHEV\Desktop\parked.csv
##doWork &user &pass sp0666to
##doWork &user &pass sp0667to
##doWork &user &pass sp0668to
spool off;
exit
If you want separate files, then move the two spool commands to the doWork.sql file.
Assuming you want to run the same set of queries for each database, I'd create a script file (e.g. main_statements.sql) containing those statements.
Then, if the list of databases was static, I'd create a second script file (e.g. run_me.sql) in the same directory, with contents along the lines of:
connect &&user/&&password#db1
##main_statements.sql
connect &&user/&&password#db2
##main_statements.sql
connect &&user/&&password#db3
##main_statements.sql
...
If, however, the databases are static but the list is contained in a database somewhere, then I'd write a script (e.g. run_me.sql) that generates a script, something like:
set echo off
set feedback off
set verify off
spool databases_to_run_through.sql
select 'connect '||username||'/'||password||'#'||database_name||chr(10)||
'##main_statements.sql'
from list_of_databases_to_query;
spool off;
##databases.run_through.sql
N.B. untested. Also, I have assumed that your table contains the usernames and passwords for each db that needs to be connected to; if that's not the case, you'll have to work out how to handle them; maybe they're all the same (in which case, you can hardcode them - or better yet, use substitution variables (e.g. &&username) to avoid having to store them in a plain file. You'd then have to enter them at runtime.
You'll also need to run the script from the same directory, otherwise you could end up with the generated script not being created in the same directory as your main_statements.sql equivalent script.
Yes it's possible, you can use oracle DBLink to connect to different dbs just like your example.
What is the best way to pass multiple values from one variable into separate records in an oracle db?
I want to take the output from:
hddlist=`iostat -Dl|awk '{print ""$1"="$(NF)}'
This returns output like this:
hdisk36=0.8
hdisk37=0.8
hdisk38=0.8
hdisk40=5.5
hdisk52=4.9
I want to insert them into a database like so:
sqlplus -s /nolog <<EOF1
connect / as sysdba
set verify off
insert into my_table ##Single Record Here
EOF1
How can I systematically separate out the values so i can create individual records that look like this:
Disk Value
--------- -------
hdisk36 0.8
hdisk37 0.8
hdisk38 0.8
hdisk40 5.5
hdisk52 4.9
I originally tried a while loop with a counter but could not seem to get it to work. An exact solution would be nice but some directional advice would be just as helpful.
Loop and generate insert statements.
sql=$(iostat -Dl | awk '{print ""$1"="$(NF)}' | while IFS== read -r k v ; do
printf 'insert into mytable (k, v) values (%s, %s);\n' "$k" "$v"
done)
This output can be passed in some manner to sqlplus, perhaps like this
sqlplus -s /nolog <<EOF1
connect / as sysdba
set verify off
$sql
EOF1
Although, depending on the line format of iostat, it might be simpler to just omit awk and parse with read directly.
You can redirect the output to a file and then use an external table
It should look something like this:
CREATE TABLE hddlist_ext_table (
disk CHAR(16),
value CHAR(3)
ORGANIZATION EXTERNAL (
TYPE ORACLE_LOADER DEFAULT DIRECTORY tab_dir
ACCESS PARAMETERS (RECORDS DELIMITED BY NEWLINE
FIELDS TERMINATED BY '=')
LOCATION ('your_file_name'));
Then you can either use this table for your data or insert-select from it to your table;
insert into my_table
select disk, value from hddlist_ext_table;
You can insert multiple rows in a single SQL statement in Oracle like this
INSERT ALL
INTO mytable (column1, column2, column3) VALUES ('val1.1', 'val1.2', 'val1.3')
INTO mytable (column1, column2, column3) VALUES ('val2.1', 'val2.2', 'val2.3')
INTO mytable (column1, column2, column3) VALUES ('val3.1', 'val3.2', 'val3.3')
SELECT * FROM dual;
If you intend to run this script automatically at intervals to then see the results of each disk, you will probably need additional columns to hold the date and time.
You might also look at sqlldr as you can specify a control file telling it what your data contains and then this will load the data into a table. It is more suited to the purpose if you are loading lots of data than SQL Plus.
