Oracle - How to pass a parameter from batch file to SQL file which contains a PL/SQL procedure

Question

I written a command in batch file which calls a .sql file which contains a pl/sql procedure. But I need to set the a parameter in PL/SQL procedure which common throughout the procedure from the batch file.

The batch file is as below.

set parameterOne=%1
set parameterTwo=%2


sqlplus -s uid/pwd filepath/filename.sql %parameterOne %parameterTwo

And the PL/SQL procedure in .sql file is as follow.

DECLARE parameterOneValue       INT;
        parameterTwoValue       INT;
BEGIN

parameterOneValue := $(parameterOne);
parameterTwoValue := $(parameterTwo);

//procedure block

END;

I need to set the parameterOne , parameterTwo attribute from batch file to parameterOneValue , parameterTwoValue in .sql files respectively. Could anyone provide solution to this?

Answer 1

Use SET DEFINE ON , and use & for variable substitution.

For example,

Your batch file:

set parameterOne=%1
set parameterTwo=%2    

sqlplus -s uid/pwd filepath/filename.sql %parameterOne %parameterTwo

SQL*Plus substitution in PL/SQL block:

parameterOneValue := &1;
parameterTwoValue := &2;

& will substitute the actual value that you set in the batch file.
