sql.connector.errors.DataError: 1136 (21S01): Column count doesn't match value count at row 1

这个错误通常是由于插入语句中列数与值的数量不匹配导致的。这可能是由于插入语句中的列数与表中的列数不匹配，或者由于插入语句中的值数量与列数不匹配。要解决这个问题，你需要检查插入语句中的列数和值的数量是否匹配，并确保它们与表中的列数相匹配。如果你使用的是INSERT INTO语句，你可以使用VALUES子句来指定要插入的值。例如，如果你要插入两个值到表中的两个列中，你可以使用以下语法：

INSERT INTO table_name (column1, column2) VALUES (value1, value2);

1136 - Column count doesn't match value count at row 1

This error message typically occurs when you are trying to insert data into a table where the number of columns in the table does not match the number of values that you are trying to insert.

For example, suppose you have a table with five columns, but you are trying to insert data for only four columns. In this case, you will receive the "Column count doesn't match value count at row 1" error message because the number of columns specified in the INSERT statement does not match the number of columns in the table.

To resolve this error, you need to ensure that the number of columns specified in the INSERT statement matches the number of columns in the table. Alternatively, you can explicitly specify the columns for which you are providing data in the INSERT statement, which helps to avoid errors if the table structure changes over time.

For example, instead of writing:

INSERT INTO my_table VALUES (1, 'John', 'Doe');

You could write:

INSERT INTO my_table (id, first_name, last_name) VALUES (1, 'John', 'Doe');

This way, if another column is added to the table in the future, your INSERT statement will not fail because you have explicitly specified which columns you are inserting data for.
