Solution 1:

Set the primary key to grow automatically. You can manually set the related table ID to self growing in the database.

As shown in the figure:

Continue to import normal.

Solution 2:

Problem Description: if the SQL is imported separately, the following error will be reported:

1 queries executed, 0 success, 1 errors, 0 warnings

Query: insert into ` fndcn_ MNG ` values (787192513, 1, ‘Dingjin’, 150150, ‘2015-12-28’, ‘prospectus’, 80100, null,’ 1 ‘, null,’ 3 ‘, 20

Error code: 1062

Duplicate entry ‘787192513’ for key ‘PRIMARY’

After checking, the primary key generation strategy is: @ generatedvalue (strategy)= GenerationType.IDENTITY ）No problem.

Delete the table with import error;

Create a new table to import data;

My problem is in the database: in the database, the primary key is not set to grow automatically. Set the primary key of the existing table to grow automatically. The SQL statement is as follows:

alter table course change course_ id   course_ id   int(10)   not null   auto_ increment ; 

Then use SQL script to import the required data, which can also easily locate errors.
