I need to create a batch file which should be parameterised
my Query
select * from glob2("parameterised value what the user is entering")
You can use set /p to query the user for input:
set /p value=Enter something:
You can then subsequently use the variable; in this case %value%.
In your code you can access the command line parameters by referring to %1 %2 etc.
Read HELP CALL and try this
#echo off
echo QUERY SELECT * FROM GLOB2 WHERE NAME="%1"

The case is that I have an SQL clause inside a unix script like:
sqlplus -s user/pass << END_SQL1 >> outfile.txt
set echo off feedback off heading off tab off;
select .....
from ....
where ...
and ...
and ... ;
END_SQL
If the outfile.txt is not empty, which means that I get a result from the above SQL, then I am running an update SQL that should change something at some DB elements.
Then I need to reuse the same SQL above to check if the DB elements that I wanted have changed indeed. So, is that possible to reuse this same SQL, but WITHOUT including this same SQL code again later at the script, instead to run it again and, moreover, even put the result at another output file, e.g. outfile2.txt ?
You can use RETURNING ... INTO ... clause inside the script
UPDATE myTable
SET col1 = <something1>
WHERE col2 = <something2>
RETURNING col3, col1 INTO v_col3, v_col1;
to return the results into the variables v_col3 and v_col1.
You could put your hairy SELECT query in a file, say select.sql. Then whenever you need to run the SQL, you could just do :
sqlplus -s user/pass #select.sql >> outfile.txt
You can adapt the output file as you wish :
sqlplus -s user/pass #select.sql >> outfile2.txt
NB : you said
If the outfile.txt is not empty, which means that I get a result from the above SQL
You probably want to use > when writing to outfile.txt : >> appends to the file, while > replaces it.
I have a batchscript mybatch in which I try to store the first user argument in a variable called FILE
set FILE = %1
if defined FILE (
echo defined
echo do something with %1
) else (
echo not defined %1
)
If I execute my batch via mybatch test1 I get always not defined test1. Why is variable FILE not defined?
You have unwanted spaces in your variable assignment, so you have defined a variable with a space in the name that always has a value beginning with a space. Your IF statement is checking if a variable without a space exists.
See Declaring and using a variable in Windows batch file (.BAT)
I recommend your first line should be:
set "FILE=%~1"
You can try like this :
#echo off
set "FILE=%~1"
if Exist "%FILE%" (
echo.
echo "%FILE%" Exist
echo do something with "%FILE%"
) else (
echo "%FILE%" is not defined
)

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'm trying to load a sql from a file in bash and execute the loaded sql. The sql file needs to be versatile, meaning it cannot be altered in order to make things easy while being run in bash (escaping special characters like * )
So I have run into some problems:
If I read my sample.sql
SELECT * FROM SAMPLETABLE
to a variable with
ab=`cat sample.sql`
and execute it
db2 `echo $ab`
I receive an sql error because by doing a cat the * has been replaced by all the files in the directory of sample.sql.
Easy solution would be to replace "" with "\" . But I cannot do this, because the file needs to stay executable in programs like DB Visualizer etc.
Could someone give me hint in the right direction?
The DB2 command line processor has options that accept a filename as input, so you shouldn't need to load statements from a text file into a shell variable.
This command will execute all SQL statements in the file, with newline treated as the statement terminator:
db2 -f sample.sql
This command will execute all SQL statements in the file, with semicolon treated as the statement terminator:
db2 -t -f sample.sql
Other useful CLP flags are:
-x : Suppress the column headings
-v : Echo the statement text immediately before execution
-z : Tee a copy of all CLP output to the filename immediately following this flag
Redirect stdin from the file.
db2 < sample.sql
In case, you have a variable used in your script and wanted to get it replaced by the shell before executed in DB2 then use this approach:
Contents of File.sql:
cat <<xEOF
insert values(1,2) into ${MY_SCHEMA}.${MY_TABLE};
select * from ${MY_SCHEMA}.${MY_TABLE};
xEOF
In command prompt do:
export MY_SCHEMA='STAR'
export MY_TAVLE='DIMENSION'
Then you are all good to get it executed in DB2:
eval File.sq |db2 +p -t
The shell will replace the global variables and then DB2 will execute it.
Hope it helps.
Is there any way to retreive the result set of a sql query in a local variable; the query is to be run in a batch file. What I am trying to do is something like this:
set varname = osql -S%dstserver% -d%dstDB% -Q"SELECT name from table_name where Id = %siteId%" %osqluser% -b
varname is my local variable.
I am quite new in sql so any help would be greatly appreciated1
Write the result to the file and then read the file. In your case you need to read the first line (and possibly trim it).
Add following parameters to your query:
osql -S%dstserver% -d%dstDB% -Q"SET NOCOUNT ON;SELECT name from table_name where Id = %siteId%" %osqluser% -b -w 9999 -h-1 -o tempres.txt
-o ...: output file (which you need to read later)
-h-1: disable header
-w 9999: to ensure that it handles correctly cases when your name is longer then default 80 characters
SET NOCOUNT ON; before real query to disable the status string like (1 row affected)
You can use for /f to iterate over the output of a command:
for /f "usebackq delims=" %%x in (`your command`) do ...
You don't need a temporary file at all; it doesn't gain you anything here (except having to think about where you may have write permissions and remember to delete the file afterwards).
for iterates line-wise over the output, tokenizing as it goes. That's why there is a delims= at the end which effectively disables any tokenizing so you don't get your output split at spaces. There are other options, such as skip=n which will skip n lines before starting processing which you can use to ignore a header or so.
Inside that loop you can then do the following:
for /f "usebackq delims=" %%x in (`your command`) do set VAR=%%x
Be very careful what you do afterwards with that variable, though, as it may contain characters the shell treats as special, such as >, <, &, etc. You may create yourself here some sort of Batch Injection vulnerability when doing something like the following:
echo %VAR%
and someone decides to put the following string in his name:
foo & rd /s q \
If you know that only a single line with usable content returns and the rest is useless junk then you can break the loop prematurely:
for /f "usebackq delims=" %%x in (`your command`) do set VAR=%%x&goto break
:break
Use set /p:
osql -S%dstserver% -d%dstDB% -Q"SET NOCOUNT ON;SELECT name from table_name where Id = %siteId%" %osqluser% -b -w 9999 -h-1 -o tempres.txt
set /p varname=<tempres.txt
(Borrowing osql parameters from van's answer)
You can write the result to a file containing set statements.
#echo off
osql -E -S servername -h-1 -Q "set nocount on; select 'set var=42'" > c:\set.bat
call c:\set.bat
echo %VAR%
This results in 42 being written to the screen. To select a name from a table, use a SQL statement like:
select 'set var=' + name from table_name where Id = %siteId%
