With the COLLATE
clause, you can override whatever the default collation is for a
comparison. COLLATE
may be used in various parts of SQL statements. Here are some
examples:
With ORDER BY
:
SELECT kFROM t1ORDER BY k COLLATE latin1_german2_ci;
With AS
:
SELECT k COLLATE latin1_german2_ci AS k1FROM t1ORDER BY k1;
With GROUP BY
:
SELECT kFROM t1GROUP BY k COLLATE latin1_german2_ci;
With aggregate functions:
SELECT MAX(k COLLATE latin1_german2_ci)FROM t1;
With DISTINCT
:
SELECT DISTINCT k COLLATE latin1_german2_ciFROM t1;
With WHERE
:
SELECT * FROM t1 WHERE _latin1 'Müller' COLLATE latin1_german2_ci = k;
SELECT * FROM t1 WHERE k LIKE _latin1 'Müller' COLLATE latin1_german2_ci;
With HAVING
:
SELECT kFROM t1GROUP BY kHAVING k = _latin1 'Müller' COLLATE latin1_german2_ci;
