Introduction

When the table to be used inside a cursor is not known to the user while creating the procedure, a ref cursor can be used to pass the name of the table dynamically as the input parameter to the procedure. The procedure also serves the purpose of being used again and again for many different tables of similar type as per the business requirement.

Hi Andrew,
In case you do not know the column(s) name in advance and wish to pass the column name dynamically just like the table name and job name you have to pass another in parameter carrying the column name.
Then your dynamic query would look as given below.

sql_stmt := 'SELECT distinct '||in_column_nm||' FROM '||in_table_nm||' WHERE JOB ='''||job_name||'''';

plz let me know in case any issue.....

But what if you don't know the columns in the table(s).
This example only works if you know that whatever table you use will always contain a column named "ename"...

I need to extract data without knowing the columns.
