查询以找出具有相同列名的两个表的匹配记录

Question

See these two sample tables:

Table 1:

id   volume  price  total

1       A      B     C

2       D      E     F

3       G      H     I

Table 2:

id   volume  price  total

1       A      B     C

2       G      H     I

3       D      E     F

I want the output which are equal from table1 and table2. I have tried many ways but no results.

output should be like this:

id volume price total

1      G    H     I

2      D     E     F

Answer 1

SELECT with inner join should work.

SELECT 
    table1.id, 
    table1.volume, 
    table1.price,
    table1.total 
FROM table1 
INNER JOIN table2 
    ON table1.volume = table2.volume 
    AND table1.price = table2.price 
    AND table1.totak = table2.price.  

Answer 2

SELECT * FROM table1 AS T1 INNER JOIN table 2 AS T2 WHERE T1.volume=T2.volume AND T1.price=T2.price AND T1.total=T2.total
