The info is not full but I'll try to help. Lets say the name of the field in the two
tables is common_field.
Then we do
SELECT all_that_is_needed FROM table1,table2 WHERE
table1.common_field=table2.common_field;
And an optimized variant:
SELECT all_that_is_needed FROM table1 LEFT JOIN table2 USING(common_field);
If in the two tables we have two columns with equal data but with different names then
we do:
SELECT all_that_is_needed FROM table1 LEFT JOIN table2 ON
table1.common_field_name_table1=table2.common_field_name_table2;
So
SELECT all_that_is_needed FROM table1 LEFT JOIN table2 USING(common_field);
is equal to:
SELECT all_that_is_needed FROM table1 LEFT JOIN table2 ON
table1.common_field=table2.common_field;
Hope that is clear.
Best regards,
Andrey
