INNER JOIN with Column Functions
You can combine a column function with an INNER JOIN, using a GROUP BY clause.
JOIN syntax: WHERE syntax:
SELECT t1.column1 AS ‘title1′, SELECT t1.column1 AS ‘title1′,
COUNT(t2.column2) COUNT(t2.column2)
FROM table1 [AS] ‘t1′ FROM table1 [AS] ‘t1′,
INNER JOIN table2 [AS] ‘t2′ table2 [AS] ‘t2′,
ON t1.column1 oper t2.column2, WHERE t1.column1 oper t2.column2,
GROUP BY t1.column1 GROUP BY t1.column1
ORDER BY t2.column2; ORDER BY t2.column2;
Where oper is a comparison operation and WHERE is used for additional filtering.
