Cách sửa lỗi 1050 table wp_commentmeta already exists năm 2024
I don't think it's anything to do with permissions of root (ie used by sudo), just a standard problem. The error makes sense and is a good warning, but I can't find where to simply overwrite or DROP all the existing objects - does that have to be coded manually into the .sql or is there an easier way to do this? If you’re getting an error that reads something like “ERROR 1050 (42S01): Table ‘customers’ already exists” when trying to create a table in MySQL, it’s probably because there’s already a table in the database with the same name. To fix this issue, either change the name of the table you’re trying to create, or check the existing table to see if it’s the one you actually need.

Result: ERROR 1050 (42S01): Table 'customers' already exists In this case, I’m trying to create a table called Solution 1The most obvious solution is to change the name of the table we’re creating:
Result: Query OK, 0 rows affected (0.02 sec) Here, I simply renamed the table to We should also be mindful that if there’s already a table with the same name as the one we’re trying to create, there’s a possibility that our desired table has already been created. In this case we wouldn’t need to recreate it (unless we had good reason). We could either just go ahead and use it, or we could alter it to suit our new requirements. Solution 2Another way to deal with this error is to suppress it. We can modify our ERROR 1050 (42S01): Table 'customers' already exists 0 statement to only create the table if it doesn’t already exist:
Result: Query OK, 0 rows affected, 1 warning (0.00 sec) In this case, we got a warning. Let’s check the warning:
Result: +---+--+------+
1 row in set (0.00 sec) The warning explicitly tells us that the table already exists. The Table REALLY Doesn’t Exist?If you believe that the table really doesn’t exist, perhaps there’s something else going on.
