这个错误提示是由于在创建MySQL表时,语法存在问题。通常是因为在定义外键约束时,语法不正确。
请检查你的SQL语句,确保语法正确。例如,检查表及列名是否正确拼写,是否使用了正确的关键字等等。
此外,外键约束的语法应该类似于这样:
```
CREATE TABLE 表名 (
列名1 数据类型,
列名2 数据类型,
列名3 数据类型,
...
FOREIGN KEY (列名1) REFERENCES 关联表名(关联列名)
);
```
在上面的语法中,列名1是在当前表中定义的列,它将作为外键列;关联表名和关联列名是外键参考的表和列。
如果你需要更多帮助,请提供更多的上下文信息,例如完整的SQL语句和MySQL版本号等。

check the manual that corresponds to your MySQL server version for the right syntax to use near 'int
引用[1]:错误提示中提到了"check the manual that corresponds to your MySQL server version for the right syntax to use near 'int'",意味着在MySQL服务器版本的手册中查找与'int'附近使用正确语法的相关信息。[1]引用[2]中提到了查询MySQL5.6参考手册,发现在MySQL5.6的参考手册中只有一个外部关键约束,而不是与'int'相关的语法。因此,可能需要查看更高版本的MySQL服务器手册来找到正确的语法。引用[3]中提到了一个解决方法,即将ppstm.executeQuery(sql)中的sql去掉,改为ppstm.executeQuery()。这可能是因为在使用PreparedStatement的预编译或编译方法时出现了错误。
check the manual that corresponds to your MySQL server version for the right syntax to use near 'auto_increament primary key
The correct syntax for creating an auto-increment primary key column in MySQL is as follows:
```sql
CREATE TABLE table_name (
column_name datatype AUTO_INCREMENT PRIMARY KEY,
...
);
```
Make sure to replace `table_name` with the actual name of your table and `column_name` with the name you want to give to the column. Additionally, specify the appropriate data type for your column.
For example, if you have a table called "users" and you want to create an auto-increment primary key column named "id", you can use the following SQL statement:
```sql
CREATE TABLE users (
id INT AUTO_INCREMENT PRIMARY KEY,
...
);
```
Remember that the specific syntax may vary depending on your MySQL server version, so always refer to the manual corresponding to your server version for accurate information.
