如何在具有相同列名的两个不同表上搜索相同数据

Question

I have two tables with different names but similar schema and different data on them. I would like to search for certain data on both tables and combine the results.

for example:

Table A: time, brand, model, color, engine_type

Table B: time, brand, model, color, engine_model

engine_type and engine_model has the same data in reality, but column name's are different

I would like to search certain engine_type or engine_model on both tables and show results. How can I do it?

Answer 1

Use a union query:

SELECT * FROM TableA WHERE engine_type = 'some value'
UNION ALL
SELECT * FROM TableB WHERE engine_model = 'some value';

Answer 2

You can use union if you dont want duplicate data as follows:

SELECT * FROM
(SELECT * FROM TableA 
UNION
SELECT * FROM TableB) t
WHERE engine_type = 'some value';

Answer 3

SELECT * FROM Table A

INTERSECT

SELECT * FROM TABLE B

THIS CODE GIVES YOU ROWS WITH COMMON DATA IN BOTH COLUMNS
