However, wanting to test how the engine compares strings and numbers:
SELECT 'match' WHERE '500' = 500;
returns 'match'; also, the following statements return the same result:
SELECT 'match' WHERE ' 500 ' = 500; SELECT 'match' WHERE '500' = 499 + 1;
Who can tell me what other SQL database engines do with the following?
CREATE TABLE test1(a VARCHAR(100));
INSERT INTO test1 VALUES('501');
INSERT INTO test1 VALUES(' 502 ');
SELECT * FROM test1 WHERE a=501;
SELECT * FROM test1 WHERE a=502;
SELECT * FROM test1 WHERE a<'502';Or how about this:
CREATE TABLE test2(b INTEGER); INSERT INTO test2 VALUES(503); INSERT INTO test2 VALUES(504); SELECT * FROM test2 WHERE b='503'; SELECT * FROM test2 WHERE b>'503';
