I am transferring a single table from MySQL 5.7 to MySQL 8.
First, I used mysqldump db_name table_name > table_name.sql in my current server(MYSQL 5.7); taken from here
Then, in my VM with MySQL 8, I used mysql -u username -p db_name < /path/to/table_name.sql.
The columns with the 'blob' data type are not correct, the other columns are okay.
the 'blob' columns went from "International Master (1973); Grandmaster (1975); FIDE Senior Trainer (2004).Alexander Genrikhovich Beliavsky was..." to "0x3C703E496E7465726E6174696F6E616C204D6173746572202831393733293B204772616E646D617374657220...".
Both databases have character-set = latin1 and collation = latin1_swedish_ci.
How can I properly transfer the 'blob' columns from MySQL 5.7 to MySQL 8?

I am trying to migrate my osclass installation to another server. I have copied all files and created a new database. When trying to import my database from backup, I get "#1215 - Cannot add foreign key constraint".

Please help.
You must create first the tables you want to reference, for example, here is one foreing key that reference one table, also the type of the key must match, follow this example an add the rest of your tables, I will show a minimum example that works in the creation of the tables, you must add the correct data of course:

I'm using the mysqldiff tool (v1.5.3) from MySQL to synchronize the schema between two databases. The databases should have the same schema, but would like to produce a file that only has the ALTER TABLE differences between them so it can (after thorough testing) be run in production.
The problem is that the mysqldiff tool produces some weirdness. For example:
ALTER TABLE `database1`.`ACCOUNT_TRANSACTIONS`
DROP INDEX MATCHING_TRANSACTION_ID,
DROP INDEX PAYEE_ID,
ADD INDEX CHECK_NUMBER (ACCOUNT_ID),
ADD INDEX PAYEE_ID (PAYEE_ID),
ADD INDEX CHECK_NUMBER (PAYEE_ID,CHECK_NUMBER);
It seems to not only drop the indexes, but tries to recreate the new index through two statements that produce an error. The final schema should have CHECK_NUMBER (ACCOUNT_ID, PAYEE_ID, CHECK_NUMBER) as the index.
What might be causing this?
Final version:
CREATE TABLE `ACCOUNT_TRANSACTIONS` (
`TRANSACTION_ID` int(12) NOT NULL AUTO_INCREMENT,
`ACCOUNT_ID` int(1) DEFAULT NULL,

I have a database for contacts and Phpmyadmin is giving me weird ids. Sometimes Ids start from 67000 sth and sometimes from 7. In my operations-->auto_increment is set to 676503. I try to change it and press go. It does not change.It keeps on giving me the same number. Also, when I click to show the data, when Ids and contacts are displayed, a column named rows is displayed. The column has only the value 1 for all contacts, as if all contacts are in row 1.
How can I fix this?

Can anyone explain why Mysql is giving me error 1280 ("wrong index for 'fk_chart_aid_aid' ") error whend I try to create the "CHART OF ACCOUNTS" table. I'm completly confused here. How can I fix this so I can create the table? The "ACCOUNT" table already exists in the database and has data in it.
Thanks for the help.

Are you getting the error after the CREATE TABLE statement, or after the subsequent CREATE INDEX?
Looks like you are attempting to name both a FOREIGN KEY constraint and an INDEX fk_chart_aid_aid. Try choosing a different name for either one of them.
Also, in the accounts table, account_id is INT(10). Try also to change the column definition in acctg_chart_of_accounts to:
`account_id` INT(10) UNSIGNED NOT NULL ,
Though, I think that mysql defaults type INT to INT(10) anyway...
I met the same issue; tried manually rename the index to a different name but don't like the idea of 'manually' and neither I don't really understand why we need to generate the index separately. so I decide to generate it within the create statement by unchecking the option of 'generate separate index statement' in 'forwarding engineer', and this fix the issue.
