Merging two tables to a view

Question

I have two tables that I merge into one view.
All rows from the two tables to be merged into one view.
Table 1 no criteria:
MATERIAL     PLANT     QUANTITY     UNIT     POSTING_DATETable 2 with criteria:
MATERIAL     PLANT     SALES_QUANTITY     UNIT     POSTING_DATE     RECORD_TYPE
Where RECORD_TYPE IN('O','U')The view should look like this:
MATERIAL     PLANT     QUANTITY     UNIT     POSTING_DATEI'm going nowhere, what do I do?

Answer 1

Hi,
Perhaps you want something like this:
CREATE OR REPLACE VIEW  table_1_and_ou_from_2
AS
SELECT     material, plant,       quantity, unit, posting_date
FROM     table1
UNION ALL
SELECT     material, plant, sales_quantity, unit, posting_date
FROM     table2
WHERE     record_type     IN ('O', 'U')
;The columns in the view will have the same names as the columns in the 1st branch of the UNION, so the 3rd column will be called quantity, not sales_quantity.
I hope this answers your question.
If not, then, as mentioned above, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all tables involved, and also post the results you want from that data (that is, the contents of the view).
Explain, using specific examples, how you get those results from that data.
Always say which version of Oracle you're using (e.g., 11.2.0.2.0).
