You are using safe update mode and you tried to update a table without a WHERE that uses a KEY column.To disable safe mode, toggle the option in Preferences -> SQL Editor -> Query Editor and reconnect.

When using the secure update mode, the update statement must use a keyword column attribute to limit the scope of the update. If you do not use keyword columns to limit the scope or update all records, you cannot use safe update mode.

The solution is to execute the following statement to set it to non secure update mode.

#Non-secure mode
SET SQL_SAFE_UPDATES=0;
#secure mode
SET SQL_SAFE_UPDATES=1;
