Question

As we can select multiple rows into single variable declared as some_table.rowtype in SQL. In the same way I want to fetch multiple row values of single column into a variable. So,

1. How can I declare it’s variable type?
2. Can I use that in where clause?
3. Can I iterate through that variable(collection) values?

I want to do it in a stored procedure to delete one or more table records matching that variable values.

Does this work for you?

DELETE FROM myTable 
WHERE myTable.ID IN 
    (SELECT ID 
     FROM myOtherTable 
     WHERE myOtherCondition)
