How can values from Table B be inserted into Table A using Inner Join or where condition in SQL?

edit

To insert values from Table B into Table A using Inner Join or where condition in SQL, you can use the INSERT INTO... SELECT statement with the INNER JOIN or WHERE clause to specify the matching records in both tables.

The syntax for this statement is as follows:

INSERT INTO TableA (column1, column2, ...)
SELECT TableB.column1, TableB.column2, ...
FROM TableA
INNER JOIN TableB ON TableA.key = TableB.key
WHERE TableB.condition = value

The above statement will insert selected columns from Table B into Table A where the key column in Table A matches the key column in Table B and the condition in Table B is equal to the specified value.

Note: The columns in both tables should have the same data type and size.
