How can I find which tables reference a given table in Oracle SQL Developer?

阅读更多关于 How can I find which tables reference a given table in Oracle SQL Developer?

问题 In Oracle SQL Developer, if I\'m viewing the information on a table, I can view the constraints, which let me see the foreign keys (and thus which tables are referenced by this table), and I can view the dependencies to see what packages and such reference the table. But I\'m not sure how to find which tables reference the table. For example, say I\'m looking at the emp table. There is another table emp_dept which captures which employees work in which departments, which references the emp

How to load a large number of strings to match with oracle database?

阅读更多关于 How to load a large number of strings to match with oracle database?

Obviously, I can load the IDs onto a temporary table and then do a join, but that would be really tedious as i have only READ privileges.
