I have written a script so that i can read from an oracle database and display it once i run the script. Is there any way that I can transfer the result to unix variable?
$ORACLE_HOME/bin/sqlplus -s /nolog<<EOF
connect useid/password#CFQ143
set pages 0 feed off
select count (platform) from platformspecific where platform='EF';
exit
EOF
I found the answer - rather than use single quotes to pass the value to a variable, you can use open and close brackets to transfer the values:
var=$($ORACLE_HOME/bin/sqlplus -s /nolog<<EOF
connect useid/password#CFQ143
set pages 0 feed off
select count (platform) from platformspecific where platform='EF';
exit
EOF)
echo $var

I am running a file via batch file
Batch File:
sqlplus admin/admin#SERVER #abc.sql > output.txt
SQL File abc.sql:
set PAGESIZE 1000
set LINESIZE 550
set echo off
set head off
set FEEDBACK OFF
select * from S_ABC
exit;
Output.txt:

Please help me remove the extra data, in the starting and end of output.txt file.
-S seems to be what you're looking for;
sqlplus -S admin/admin#SERVER #abc.sql > output.txt
-S[ILENT]
Suppresses all SQL*Plus information and prompt messages, including the command prompt, the echoing of commands, and the banner normally displayed when you start SQL*Plus. If you omit username or password, SQL*Plus prompts for them, but the prompts are not visible. Use SILENT to invoke SQL*Plus within another program so that the use of SQL*Plus is invisible to the user.
I am new to unix shell scripting and need a suggestion.
I have shell script which connects to the oracle db fetch the value and assign it outpt variable as mentioned below.
outpt=$(sqlplus Username/Pass#(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(Host=10.255.244.15)(Port=1674))(CONNECT_DATA=(SID=abc01))) <<EOF
set pages 0 echo off feed off
select max(date_sent) from test;
exit;
EOF
)
In windows we close the connection explicitly after executing the query. Is the code above implicitly do that for me or i have to explictly close connection.
If yes . Please help.
I am creating a shell script where I have saved entries from a text file into an array. Those values are properly stored and show the correct contents. One of those entries contains a simple query and I want to pass it to a sql file. With that sql query I want to save the results into a text file.
Here is the part of the code that calls the sql file to run the sql script
PURGE_SITES=purge_site.txt
logmsg "USERID - $PURGES_SITE" n
QUERY=${Unix_Array[4]}
echo $QUERY
sqlplus -s $USER/$PASS <<EndSQL
#purges_sites.sql $PURGE_SITES '$QUERY'
EXIT SQL.SQLCODE
EndSQL
for now query stored in ${Unix_Array[4]} is "select -1 from dual"
Here is the file contents of the .sql file
set echo off ver off feed off pages 0
accept fname prompt 'Loading Sites...'
spool &1;
&2
/
spool off
It gives me error and reads &2 as "&2" instead of the query saved in the variable. However when i edit the .sql file and add something beforehand, it will display the correct data from the variable.
Here is the output
select -1 from dual
File Name===> results.txt
select -1 from dual
Loading Sites...SP2-0042: unknown command "&2" - rest of line ignored.
SP2-0103: Nothing in SQL buffer to run.
Here is the output if I add something before &2.
select -1 from dual
File Name===> results.txt
select -1 from dual
Loading Sites...select * from table_table select -1 from dual
*
ERROR at line 1:
ORA-00933: SQL command not properly ended
I typed in select * from table_table before &2.
So its actually retrieving the value from the variable but something needs to come beforehand in order to pass correctly.
Is there a system execute command in oracle that will execute a query? &2 just by itself is not allowed.
Wont this help you?
PURGE_SITES=purge_site.txt
logmsg "USERID - $PURGES_SITE" n
QUERY=${Unix_Array[4]}
echo $QUERY
# FRAME YOUR QUERY, PROMPTING USER IN SHELL ITSELF AND SEND TO SQLPLUS DIRECTLY
# BEWARE SQL INJECTION POSSIBLE
# YOU CAN REDIRECT THE SQLPLUS OUTPUT TO A FILE LIKE THIS, NO SPOOL NEEDED
sqlplus -s $USER/$PASS <<EndSQL >> $OUTPUT_FILE
set echo off ver off feed off pages 0
$QUERY
/
EXIT SQL.SQLCODE
EndSQL
i am new to bash scripting and i was wondering if anyone could help me with the following.
I am trying to retrieve the competition name from a Oracle database using competition_id using the following statement:
select name, competition_type from competitions where competition_id=' ';
However i want to use a seperate text file whcih has a list competition_ids i want to identify, i want my script to find the name and type of all my ids and output the results in a txt file. this is what i have so far:
#!/bin/bash
echo Start Executing SQL commands
cat comps_ids.txt | while read ID
var=$ID
do
sqlplus "details"
<< EOF
select name, competition_type
from competitions
where competition_id=$var;
exit;
EOF
I tried to add a done at the end but i get "unexpected line ending" error message. Can anyone solve this?
Many thanks in advance :)
I'm not sure what your command line should look like, but it's more like
sqlplus "details" <<EOF
select name, competition_type from competitions where competition_id=$val;
exit;
EOF
If your list of IDs isn't too big, it may be better idea to make a ,-separated list and single query.
#!/bin/bash
function get_comp () {
sqlplus -S user/pass#database << EOF
set pagesize 0
set feedback off
set head off
select name, competition_type
from competitions
where competition_id=$1;
EOF
}
for id in $* ; do
get_comp $id
done
Put it in a file (get_comps.sh), and then call it like this
$ ./get_comps.sh < comp_ids.txt > text_file_out.txt
-S makes sqlplus quieter
The other setting make it return just your data, not row headers or anything else.
Of course the database credentials will be stored in your history, and available to other users using 'ps' or 'top'.
This is also horribly inefficient because it connects to the database for each row in your original file. If you have a lot of rows, you might try using python or ruby as their database stuff is pretty easy to use.
I need to loop a oracle sqlplus query using bash.
my scenario is like this. I have a set of names in a text file and i need to find out details of that names using a sqlplus query.
textfile.txt content:
john
robert
samuel
chris
bash script
#!/bin/bash
while read line
do
/opt/oracle/bin/sqlplus -s user#db/password #query.sql $line
done < /tmp/textfile.txt
sql query: query.sql
set verify off
set heading off
select customerid from customers where customername like '%&1%';
exit
problem is when I run the script I get errors like
SP2-0734: unknown command beginning
"robert..." - rest of line ignored.
can someone tell me how to solve this?
The way I do this all the time is as follows:
#!/bin/bash
cat textfile.txt |while read Name
do
sqlplus -s userid/password#db_name > output.log <<EOF
set verify off
set heading off
select customerid from customers where customername like '%${Name}%'
/
exit
EOF
Bash will auto magically expand ${Name} for each line and place it into the sql command before sending it into sqlplus
Do you have set define on ? Is your wildcard & ? You could check glogin.sql to know.
And yes, establishing n connections to pass n queries is probably not a good solution. Maybe it's faster for you to develop and you will do that one time, but if not, you should maybe think of crafting a procedure.
