Index Exceeding Max Length??????
Does anyone know why the following code generates the following error?
CREATE TABLE test1
(
test text(256) NOT NULL,
PRIMARY KEY (test(256))
);
CREATE TABLE test2
(
id int NOT NULL,
test1 text(256) NOT NULL,
test2 text(256) NOT NULL,
PRIMARY KEY (id),
FOREIGN KEY (test1(256)) REFERENCES test1 (test)
);
CREATE UNIQUE INDEX test4_index ON test5
(
test1(256),test2(256)
);
#1071 - Specified key was too long; max key length is 1000 bytes
I thought 256+256=512
