I am trying to create a table in MySQL with the query
CREATE TABLE ofRosterGroups (
rosterID BIGINT NOT NULL,
rank TINYINT NOT NULL,
groupName VARCHAR(255) NOT NULL,
PRIMARY KEY (rosterID, rank),
INDEX ofRosterGroup_rosterid_idx (rosterID)
);
but seems like it is throwing error everytime I made updates too. I don't know what is going wrong with it.
Error coming up is
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use
near 'rank TINYINT NOT NULL, groupName
VARCHAR at line 3
解決方案
MySQL 8.0.2 added support for the window rank function, making it a reserverd word.
You could escape it using backticks (`):
CREATE TABLE ofRosterGroups (
rosterID BIGINT NOT NULL,
`rank` TINYINT NOT NULL, -- Here
groupName VARCHAR(255) NOT NULL,
PRIMARY KEY (rosterID, `rank`), -- And here
INDEX ofRosterGroup_rosterid_idx (rosterID)
);
But it may be a better idea to just use a name that isn't a reserved word, such as rosterRank instead of rank:
CREATE TABLE ofRosterGroups (
rosterID BIGINT NOT NULL,
rosterRank TINYINT NOT NULL, -- Here
groupName VARCHAR(255) NOT NULL,
PRIMARY KEY (rosterID, rosterRank), -- And here
INDEX ofRosterGroup_rosterid_idx (rosterID)
);
