Can't export my database from mysql workbench

Question

I am trying to export my database from MySQL Workbench but I get this during the export progress:

Running: mysqldump.exe --defaults-file=\"c:\\users

Answer 1

in version 8, I modified "wb_admin_export.py" and restart workbench. works for me

def start(self):
.
.
.
    title = "Dumping " + schema
    title += " (%s)" % table
    # description, object_count, pipe_factory, extra_args, objects
    args = []
    args.append('--column-statistics=0')

class ViewsRoutinesEventsDumpData(DumpThread.TaskData):
    def __init__(self, schema, views, args, make_pipe):
        title = "Dumping " + schema + " views and/or routines and/or events"
        if not views:
           extra_args = ["--no-create-info"]
        else:
            extra_args = []
        DumpThread.TaskData.__init__(self,title, len(views), ["--skip-triggers", " --no-data" ," --no-create-db", "--column-statistics=0"] + extra_args + args, [schema] + views, None, make_pipe)```

To summarize what I did from the helpful comments of @JustinLaureno and @Mohd.Shaizad, tested on MySQL Workbench 8.0.18:

• Navigate to C:\Program Files\MySQL\MySQL Workbench 8.0 CE\modules

• Edit the file wb_admin_export.py (you need admin permissions for this)

• amend the line:

  skip_column_statistics = True if get_mysqldump_version() > Version(8, 0, 2) and self.owner.ctrl_be.target_version < Version(8, 0, 0) else False
  

• to:

  skip_column_statistics = True
  

• DO NOT add inline comments or it won't work!

  skip_column_statistics = True # This won't work
  

• Restart MySQL Workbench

• Perform the export

You can use native MySQL Workbench "Migration wizard" to migrate data without errors. It can be found in menu Database -> Migration Wizard It can transfer data "online" but I didn't found an option to create a dump file with it. It is a pretty good solution for migrations

Answer 4

I had the same issue 5 minutes ago.

I fixed it by adding in my mysqldump command --column-statistics=0. Do it and it should work.

In my case it's a phing task but you should get the idea.

Answer 5

I found this condition in wb_admin_export.py instead of a commented --column-statistics=0. you can remove the else False condition, or change it to else True.

skip_column_statistics = True if get_mysqldump_version() > Version(8,
0, 2) and self.owner.ctrl_be.target_version < Version(8, 0, 0) else
True

Answer 6

Go to C:\Program Files\MySQL\MySQL Workbench 8.0 CE\modules and open this file wb_admin_export.py and uncomment "--column-statistics=0" then Restart the workbench
