SQL*Plus ## behaviour with spaces in the parent script path - oracle

Question

I have to
Connect
Call sql-script
Exit sqlplus
So, I've created a sql-script run.sql:
set def on
WHENEVER SQLERROR EXIT ROLLBACK
conn &2
#"&1";
exit;
For example, I have some sql-scripts in a folder "c:\folder with spaces\":
a) install.sql with contents:
prompt Hello
##a.sql
##b.sql
b) and of course I have a.sql and b.sql files in the folder with some actions.
So, I try to run my script:
sqlplus /nolog #"Path_to_Run\run.sql" \"c:\folder with spaces\install.sql\" user/pass#server
And I got an output:
Hello
SP2-0310: unable to open file "c:\folder.sql"
So, it can open install.sql, but cannot open ##a.sql. He tries to run such script:
#c:\folder with spaces\a.sql
But how can I place quotes here? He should run the script a.sql inside the folder "c:\folder with spaces\".

Answer 1

You could split your parameters so that run.sql contains
set def on
WHENEVER SQLERROR EXIT ROLLBACK
conn &2
host cd "#3"
#"&1";
exit;
And invoke it with
sqlplus /nolog #"Path_to_Run\run.sql" \"c:\folder with spaces\" install.sql user/pass#server
Note that it might need some tuning, it does not work on my computer because of cygwin messing with its own cd.

Answer 2

Thanks to Alex Poole, the answer is in documentation
SP2-0310 Error when Calling a SQL Script in Another Script using ## and the Path to the Parent Script Contains Spaces (Doc ID 745780.1)
And there are three solutions:
Use the 8dot3 notation. E.g. Use PROGRA~1 instead of "Program Files".
Avoid saving the sql scripts on a path containing spaces in the folder names.
cd to the directory containing the script instead of providing the full path when invoking the script in SQL*Plus.
First method doesn't work for me in Windows 7 (there are a lot of work to set up 8dot3 in Win7). I get:
>cd c:\folder~1
The system cannot find the path specified.
Second method doesn't work for me too, I cannot operate these folders. I have to use them as is.
And the third method works fine (but in another way than in the previous message):
cd "c:\folder with spaces"
sqlplus /nolog #c:\run\run.sql install.sql user/pass#server
So, you have to change dir before sqlplus, host cd doesn't work.
Thank you, guys.
