Pass parameter to SQL file from within another SQL file - sql

I thought for sure there would be an SO question on this, but I haven't been able to find one.
I have 2 SQL files, myFile1.sql and myFile2.sql. myFile1.sql calls myFile2.sql like so:
-- In myFile1.sql:
#scripts/myFile2
This works with no problem, but now I'd like to pass an argument to the file. I've tried doing the following, with no success (results in a File Not Found exception):
#scripts/myFile2 'ImAnArgument'
Does anyone know what the syntax would be to do this?

I'm guessing your problem is that scripts/myFile2.sql is a relative path from the script it is located in. If that is so, then it is following that path from the directory where SQL*Plus was started (the current working directory). If this is the problem, then it's not the parameter that is the issue, but rather that SQL*Plus can't find the file. In this case, you should use ##, which invokes the path relative to the file it's located in.
The parameter should work just as you proposed (documentation). Parameters provided when invoking a file are placed into substitution variables (rather than bind variables) and can be referenced by using an ampersand followed by the argument number. In your example, 'ImAnArgument' would be &1.

After many attempts, I wasn't able to pass a parameter in (and I still don't understand why not). But here is what I did to get the same affect:
-- In myFile1.sql:
DEFINE my_arg = 'ImAnArgument';
#scripts/myFile2
Then
-- In myFile2.sql
-- Do stuff using the variable my_arg, such as
SELECT my_arg FROM my_table;

SCIP - run (nearly) same LP on different instances

I have an LP, formulated in the modelling language Zimpl, that I want to run on many instances, which are in different files.
Additionally, I want to change one parameter in this LP.
For a single call, my file test.zpl looks like this:
param FILE := "file1.dat"
param BOUND := 42
[test_body: Rest of LP]
Now I want to change those two parameters. SCIP has the -c option, to execute some command. But I cannot find by which command to achieve this. All parameter changes I found affect the algorithm, not the data.
The command change to change the problem does not seem to allow new parameters/variables.
In the end, I expect the solution to look something like
scip -c "[set my parameters]; read test_body.zpl; optimize; quit"
How do I set these problem parameters?
I am not aware of any commands that support the modification of model parameters as you wish. However, if you don't hardcode the value of param BOUND in the .zpl file (instead, move the value to the .dat file and use a proper read command in the model), then you could procede as follows:
Make a copy of your data file such that each copy contains a distinct value of param BOUND
Call scip.exe separately with each data file (you could also use a simple batch script)

pentaho PDI passing uservariable in command line

I am trying to run a Transformation/Job by passing a user variable in command line.
I have tried by passing variable value as below.
sh pan.sh -file='test.ktr' '-param:input_directory=/path/to/directory' -level=basic
where input_directory is variable in transformation and i mentioned it as ${input_directory}
But when I do this, the pan is unable to find the variable value. It is throwing error as below
Could not list the contents of "file:///home/user1/pdi8.1/data-integration8.1/${input_directory}" because it is not a folder.
can someone help me on this. Thank you
To pass named parameters to your job or transformation, the parameters need to be defined in the properties window, shown here for a transformation. The default value is not needed, but works well for testing. Pay attention to capitalization.
So the pieces of the puzzle are:
From the command line, pass the parameter like -param:yourparam=yourvalue
Define this same parameter in the highest-level job or transformation
Use it as you would use any variable, with ${yourparam}
i think the parameter names to be used in job should be ${PARAM_NAME1}
using command line i follow the below convention
call "{Replace with kitchen.bat File Path}" /file:"{Replace with JOB File Path}" "-param:PARAM_NAME1=PARAM_VALUE1" "-param:PARAM_NAME2=PARAM_VALUE2"

How do i set working directory in sql developer in code

I'm using sql developer.
I want to run some scripts.
I don't want to have to include the folder name in the call to each script.
But I also want to use a variable to include the directory to look in (the working directory).
I can do this but i am having trouble with folder names with spaces (this is in windows).
Can anyone help me work out how to do this without having to rename my folder to remove spaces?
define dir="c:\Users\xx\Google Drive\Analytics\Recruitment\NSL\2. Data Understanding\Code"
#&dir\cb_nsl_impairments.sql;
Returns error
SP2-0310: Unable to open file: "c:\Users\xx\Google.sql"
Oops. Solved it.
Just needed double quotes around the script call:
#"&dir\cb_nsl_impairments.sql"

Check if Windows batch variable starts with a specific string

How can I find out (with Windows a batch command), if, for example, a variable starts with ABC?
I know that I can search for variables if I know the whole content (if "%variable%"=="abc"), but I want that it only looks after the beginning.
I also need it to find out where the batch file is located, so if there is a other command that reveals the file's location, please let me know.
Use the variable substring syntax:
IF "%variable:~0,3%"=="ABC" [...]
If you need the path to the batch file without the batch file name, you can use the variable:
%~dp0
Syntax for this is explained in the help for the for command, although this variable syntax extends beyond just the for command syntax.
to find batch file location use %0 (gives full patch to current batch file) or %CD% variable which gives local directory

Execute scripts by relative path in Oracle SQL Developer

First, this question relates to Oracle SQL Developer 3.2, not SQL*Plus or iSQL, etc. I've done a bunch of searching but haven't found a straight answer.
I have several collections of scripts that I'm trying to automate (and btw, my SQL experience is pretty basic and mostly MS-based). The trouble I'm having is executing them by a relative path. for example, assume this setup:
scripts/A/runAll.sql
| /A1.sql
| /A2.sql
|
/B/runAll.sql
/B1.sql
/B2.sql
I would like to have a file scripts/runEverything.sql something like this:
##/A/runAll.sql
##/B/runAll.sql
scripts/A/runAll.sql:
##/A1.sql
##/A2.sql
where "##", I gather, means relative path in SQL*Plus.
I've fooled around with making variables but without much luck. I have been able to do something similar using '&1' and passing in the root directory. I.e.:
scripts/runEverything.sql:
#'&1/A/runAll.sql' '&1/A'
#'&1/B/runAll.sql' '&1/B'
and call it by executing this:
#'c:/.../scripts/runEverything.sql' 'c:/.../scripts'
But the problem here has been that B/runAll.sql gets called with the path: c:/.../scripts/A/B.
So, is it possible with SQL Developer to make nested calls, and how?
This approach has two components:
-Set-up the active SQL Developer worksheet's folder as the default directory.
-Open a driver script, e.g. runAll.sql, (which then changes the default directory to the active working directory), and use relative paths within the runAll.sql script to call sibling scripts.
Set-up your scripts default folder. On the SQL Developer toolbar, Use this navigation:
Tools > Preferences
In the preference dialog box, navigate to Database > Worksheet > Select default path to look for scripts.
Enter the default path to look for scripts as the active working directory:
"${file.dir}"
Create a script file and place all scripts associated in it:
runAll.sql
A1.sql
A2.sql
The content of runAll.sql would include:
#A1.sql;
#A2.sql;
To test this approach, in SQL Developer, click on File and navigate and open the script\runAll.sql file.
Next, select all (on the worksheet), and execute.
Through the act of navigating and opening the runAll.sql worksheet, the default file folder becomes "script".
I don't have access to SQL Developer right now so i can't experiment with the relative paths, but with the substitution variables I believe the problem you're seeing is that the positional variables (i.e. &1) are redefined by each start or #. So after your first #runAll, the parent script sees the same &1 that the last child saw, which now includes the /A.
You can avoid that by defining your own variable in the master script:
define path=&1
#'&path/A/runAll.sql' '&path/A'
#'&path/B/runAll.sql' '&path/B'
As long as runAll.sql, and anything that runs, does not also (re-define) path this should work, and you just need to choose a unique name if there is the risk of a clash.
Again I can't verify this but I'm sure I've done exactly this in the past...
you need to provide the path of the file as String , give the patch in double quote it will work
**
For Example
#"C:\Users\Arpan Saini\Zions R2\Reports Statements and Notices\Patch\08312017_Patch_16.2.3.17\DB Scripts\snsp.sql";

How to pass parameters in file
#A1.sql; (Parameter)
#A2.sql; (Parameter)
This is not absolute or relative path issue. It's the SQL interpreter issue, where by default it will look for files which are having .sql extention.
Please make sure to modify the file name to file_name.sql
Ex: if workspace is having file name called "A", then move the file from A to "A.sql"
