Run a SELECT from the command prompt:
dbisql -nogui -c "UID=user; PWD=pwd;DSN=dsn" select net_sls_ttl,svc_ttl,void_ttl,tax_coll_ttl from dly_sys_ttl where business_date=TODAY()
Output is:
net_sls_ttl svc_ttl void_ttl tax_coll_ttl

15230.67 1587.67 -76.50 1151.21
(1 rows)
How to suppress header, format the output, and delete the last line such that output is:
15230.67,1587.67,-76.50,1151.21
Thanks!

I have created a a script that execute sql (Sybase)
#!/bin/bash
command=$(
isql -U databasename_dba -P password -b <<EOF!
select label1, label2 from TABLE
go
EOF!
)
echo "$command" >> output_file.csv):
All good so far, the file is produced:
But as you can see, the output is represented in 1 column.
Is possible to add "Headers" and divide the column is 2 columns, my desired output would be:
Try to remove -b.
#!/bin/bash
command=$(
isql -U databasename_dba -P password <<EOF!
select label1, label2 from TABLE
go
EOF!
)
echo "$command" >> output_file.csv):
I have one big file containing data, for example :
123;test/x/COD_ACT_008510/descr="R08-Ballon d''eau"
456;test/x/COD_ACT_008510/descr="R08-Ballon d''eau"
In reality, there is much more column but I simplified here.
I want to treat each line, and do some sqlplus treatment with them.
Let say that I have one table, with two column, with this :
ID | CONTENT
123 | test/x/COD_ACT_333/descr="Test 1"
456 | test/x/COD_ACT_444/descr="Test 2"
Let say I want to update the two lines content value to have that :
ID | CONTENT
123 | test/x/COD_ACT_008510/descr="R08-Ballon d''eau"
456 | test/x/COD_ACT_008510/descr="R08-Ballon d''eau"
I have a lot of data and complex request to execute in reality, so I have to use sqlplus, not tools like sqlloader.
So, I treat the input file on 5 multi thread, one line at each time, and define "\n" like separator to evict quote conflict :
cat input_file.txt | xargs -n 1 -P 5 -d '\n' ./my_script.sh &
In "my_script.sh" I have :
#!/bin/bash
line="$1"
sim_id=$(echo "$line" | cut -d';' -f1)
content=$(echo "$line" | cut -d';' -f2)
sqlplus -s $DBUSER/$DBPASSWORD#$DBHOST:$DBPORT/$DBSCHEMA #updateRequest.sql "$id" "'"$content"'"
And in the updateRequest.sql file (just containing a test) :
set heading off
set feed off
set pages 0
set verify off
update T_TABLE SET CONTENT = '&2' where ID = '&1';
commit;
And in result, I have :
01740: missing double quote in identifier
If I put “verify” parameter to on in the sql script, I can see :
old 1: select '&2' from dual
new 1: select 'test/BVAL/COD_ACT_008510/descr="R08-Ballon d'eau"' from dual
It seems like one of the two single quotes (used for escape the second quote) is missing...
I tried everything, but each time I have an error with quote or double quote, either of bash side, or sql side... it's endless :/
I need the double quote for the "descr" part, and I need to process the apostrophe (quote) in content.
For info, the input file is generated automatically, but I can modify his format.
With GNU Parallel it looks like this:
dburl=oracle://$DBUSER:$DBPASSWORD#$DBHOST:$DBPORT/$DBSCHEMA
cat big |
parallel -j5 -v --colsep ';' -q sql $dburl "update T_TABLE SET CONTENT = '{=2 s/'/''/g=}' where ID = '{1}'; commit;"
But only if you do not have ; in the values. So given this input it will do the wrong thing:
456;test/x/COD_ACT_008510/descr="semicolon;in;value"
how to execute a HIVE query in background when the query looks like below
Select count(1) from table1 where column1='value1';
I am trying to write it using a script like below
#!/usr/bin/ksh
exec 1> /home/koushik/Logs/`basename $0 | cut -d"." -f1 | sed 's/\.sh//g'`_$(date +"%Y%m%d_%H%M%S").log 2>&1
ST_TIME=`date +%s`
cd $HIVE_HOME/bin
./hive -e 'SELECT COUNT(1) FROM TABLE1 WHERE COLUMN1 = ''value1'';'
END_TIME=`date +%s`
TT_SECS=$(( END_TIME - ST_TIME))
TT_HRS=$(( TT_SECS / 3600 ))
TT_REM_MS=$(( TT_SECS % 3600 ))
TT_MINS=$(( TT_REM_MS / 60 ))
TT_REM_SECS=$(( TT_REM_MS % 60 ))
printf "\n"
printf "Total time taken to execute the script="$TT_HRS:$TT_MINS:$TT_REM_SECS HH:MM:SS
printf "\n"
but getting error like
FAILED: SemanticException [Error 10004]: Line 1:77 Invalid table alias or column reference 'value1'
let me know exactly where I am doing mistake.
Create a document named example
vi example
Enter the query in the document and save it.
create table sample as
Select count(1) from table1 where column1='value1';
Now run the document using the following command:
hive -f example 1>example.error 2>example.output &
You will get the result as
[1]
Now disown the process :
disown
Now the process will run in the background. If you want to know the status of the output, you may use
tail -f example.output
True #Koushik ! Glad that you found the issue.
In the query, bash was unable to form the hive query due to ambiguous single quotes.
Though SELECT COUNT(1) FROM Table1 WHERE Column1 = 'Value1' is valid in hive,
$hive -e 'SELECT COUNT(1) FROM Table1 WHERE Column1 = 'Value1';' is not valid.
The best solution would be to use double quotes for the Value1 as
hive -e 'SELECT COUNT(1) FROM Table1 WHERE Column1 = "Value1";'
or use a quick and dirty solution by including the single quotes within double quotes.
hive -e 'SELECT COUNT(1) FROM Table1 WHERE Column1 = "'"Value1"'";'
This would make sure that the hive query is properly formed and then executed accordingly. I'd not suggest this approach unless you've a desperate ask for a single quote ;)
I am able to resolve it replacing single quote with double quote. Now the modified statement looks like
./hive -e 'SELECT COUNT(1) FROM Table1 WHERE Column1 = "Value1";'
I have an sql query that returns a date.
I call this query from a shell script and would like to assign this value to the variable called datestart (and use it later). Here is my code. Without the datestart assignment the query works fine.
#!/bin/sh
firstname="-Upgsql"
dbname="statcoll"
portname="-p5438"
datestart=(psql $firstname $portname $dbname<< EOF
SELECT MIN(latestrefdate) FROM (SELECT MAX(referencedate) AS latestrefdate FROM statistics WHERE transactionname IN(SELECT DISTINCT transactionname FROM statistics WHERE platform = 'Smarties')GROUP BY transactionname) as earliest;
EOF
)
echo $datestart
but the result is this :
Syntax error: word unexpected (expecting ")").
I have no idea where should I insert that closing bracket. Any hint is appreciated.
Instead of brackets in variable assignment you need to use $(...) for BASH or `...` for sh.
Try this:
#!/bin/sh
firstname="-Upgsql"
dbname="statcoll"
portname="-p5438"
datestart=`psql -t --pset="footer=off" --user="$firstname" --port="$portname" -d "$dbname"<<EOF
SELECT MIN(latestrefdate) FROM (SELECT MAX(referencedate) AS latestrefdate FROM statistics WHERE transactionname IN (SELECT DISTINCT transactionname FROM statistics WHERE platform = 'Smarties') GROUP BY transactionname) as earliest;
EOF
`
echo "$datestart"
There is probably a very simple solution here, but I am probably not using the right search terms. I have a sql query running in a shell script. I get the results I am looking for, however, I am also getting the sql query as part of of the result. How can I suppress this and just show the result?
My script:
#!/usr/bin/sh
db2 connect to MYDB >/dev/null 2>&1;
db2 -x -v "select A, B, C from MYTABLE";
db2 connect reset >/dev/null 2>&1;
And my output looks like this:
select A, B, C from MYTABLE
AAA BBB CCC
AAA BBB CCC
I would like to get rid of the first row and just show the result. What am I missing?
Thanks in advance for your help!
The -v option for the DB2 command line processor causes the current statement being executed to be printed in the output.
Remove the -v from your command and you'll get only the results of the query.
if you just want to skip the 1st row from your output you could:
yourscript.sh | tail -n +2
test with seq:
kent$ seq 5|tail -n +2
2
3
4
5
Try this
db2 -o query
