How to solve the problem that thinkphp query results cannot be saved

1. Database connection problem

If the query results cannot be saved, the first thing to confirm is whether the database connection is normal. Here, we can check whether the database connection is normal through the following methods:

1. Check whether the database connection information is correct

When using thinkphp When querying, you must ensure the correctness of the database connection information, including database server address, database name, user name, password, etc. If there are any errors in the input, the database connection will fail and the query results cannot be stored.

2. Check whether the database server is running normally

If the database server goes down or restarts, it will not be possible to connect to the database, so the query results cannot be saved. It is necessary to check whether the database server is running normally and can be connected.

3. Check database permission settings

When performing thinkphp queries, you need to ensure that the database user has read and write permissions to the database. If the permissions are set improperly, the query results will not be saved.

2. Other problems

In addition to the above database connection problems, there are also the following situations that may cause the query results to fail to be saved:

1. Incorrect query conditions

If you set the wrong query conditions when using thinkphp to query, you will get empty query results and you will not be able to save them. . Therefore, when using query statements, ensure the correctness of the query conditions.

2. Field name or table name error

If the field name or table name in the query statement is set incorrectly, the query result will be empty. As a result, saving cannot be performed. Therefore, when using query statements, pay attention to the correctness of field names and table names.

3. Solution

If the query results cannot be saved, we can troubleshoot and solve the problem from the following aspects:

1. Check whether the database connection information is correct and whether the database server is running normally.

2. Check the permission settings of the database user to ensure that they have read and write permissions to the database.

3. Check whether the query conditions, field names and table names are set correctly.

4. If the problem still cannot be solved, you can try to restart the database server, or use other query statements to query.
