未知的SQL错误

Question

我正在创建一个表并产生SQL错误，我看不出原因。

    statement.executeUpdate("drop table if exists group");
    String group = "CREATE TABLE group" +
         "(groupId INT PRIMARY KEY NOT NULL, " + 
         "groupLeader INT NOT NULL, " + 
         "groupMembers INT NOT NULL, " + 
         "goals INT NOT NULL)";
    statement.executeUpdate(group);

Answer 1

GROUP是保留字。试试：

statement.executeUpdate("drop table if exists `group`");
    String group = "CREATE TABLE `group`" +
         "(groupId INT PRIMARY KEY NOT NULL, " + 
         "groupLeader INT NOT NULL, " + 
         "groupMembers INT NOT NULL, " + 
         "goals INT NOT NULL)";
    statement.executeUpdate(group);
