Table cannot be created in mysql -Error 1064

问题

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

回答1:

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)
);
