utPLSQL: How can i compare two tables?

Question

Lets say i have table 1 and table 2. Table 2 is the updated version of table one. It can have same or updated structure, columns and data. I want to compare those two tables.

Answer 1

My requirement was to compare columns, data and constraints of two tables using utPLSQL. i met my requirement by using native refcursors.

For data comparison:

OPEN p_store FOR SELECT * FROM customers@dblink2;
OPEN p_store2 FOR SELECT * FROM customers2@dblink2;
ut.expect(p_store).to_equal(p_store2);

For column comparison:

OPEN p_store FOR
SELECT
    A.COLUMN_NAME,
    A.DATA_TYPE,
    A.DATA_LENGTH
FROM
    (SELECT * FROM USER_TAB_COLUMNS@dblink2 WHERE TABLE_NAME  = 'CUSTOMERS') A;
OPEN p_store2 FOR
SELECT
  B.COLUMN_NAME,
  B.DATA_TYPE,
  B.DATA_LENGTH
FROM
  (SELECT * FROM user_tab_columns@dblink2 WHERE table_name = 'CUSTOMERS') B;
ut.expect(p_store).to_equal(p_store2);

I using utPLSQL V3. If you're using v2 then utassert.eqtable can be used.
