Can you evaluate an expression and assign the result to a substitution variable? In my case, I need to call an old script which contains a substitutions variable. I need to calculate a value for that variable before calling the script. I'm using Oracle SQL and SQL*Plus Here's the basic problem: def this_num = 2+2 @old_script Inside old_script.sql select '&this_num' from dual; -- Probably shouldn't change this Yields: '2+2' Is there a way to force evaluation so that the substitution variable gets the result of an expression rather than the expression itself? def this_num = 2+2 @old_script In

For test purposes, I would like to insert a large amount of data (approx. 1 MByte) into an Oracle CLOB column. In order to keep the test simple, I want to do that without having to write a test program using C++ or Java; instead, I want to use SQL*PLus. Does Oracle's SQL syntax offer any possibility to do that? I.e. instead of the EMPTY_CLOB() function, I would need something like MAKE_CLOB('x', 1000000) that makes a CLOB by repeating a character 1,000,0000 times. (Note: I specifically do not want to insert the CLOB by using a SELECT clause within the INSERT statement to select a large CLOB

I got two files in C:\temp\SQL\alex.sql and in C:\temp\alex.ps1 . In C:\temp\SQL\alex.sql , that is simply select count(*) from user_tables; quit; In C:\temp\alex.ps1 , that is $cmd = "sqlplus"; $args = "user/password@server/sid @C:\temp\SQL\alex.sql"; &$cmd $args; I tried the command in Command Prompt sqlplus user/password@server/sid @C:\temp\SQL\alex.sql which executed perfectly!
