Description
I try to alter table to add a composite primary key with "if not exists clause" to a table. One of these column is already in a composite unique index with an other column.
I get warning code 1061 "Multiple primary key defined".
But without "IF NOT EXISTS", it works fine.
This is my example :
CREATE TABLE `HORIZON` ( |
`ID` BIGINT(20) NOT NULL, |
`RANK` MEDIUMINT(4) NOT NULL, |
`CHECK_POINT` BIGINT(20) NOT NULL, |
UNIQUE INDEX `HORIZON_UIDX01` (`ID`, `RANK`) |
) COLLATE='utf8_general_ci' ENGINE=InnoDB ; |
 |
ALTER TABLE `HORIZON` ADD PRIMARY KEY IF NOT EXISTS (`ID`, `CHECK_POINT`); /* warning code 1061 */ |
ALTER TABLE `HORIZON` ADD PRIMARY KEY (`ID`, `CHECK_POINT`); /* works fine */ |
