There are multiple table in my Oracle DB that I plan to migrate into Mysql db.
The way I imagine is that
1.Go to each oracle table to execute some sort of cmd to generate the create statement that I can paste in my Mysql prompt.
However, due to my newbie knowledge in db, Does it really exist such simple cmd to do that?
If yes, can I even execute this idea batchly?

I execute the following statement from the cmd terminal to import my MySQL Database:
mysql u- root p- database < "C:\Users\Tom\data.sql"
When I open my MySQL Database from the MySQL Workbench I've realised that more tables have been created that I don't recognise. Basically, what is happening is the stored procedures/routines I have created seem to be automatically running and thus creating many more tables? I don't want this, I'd rather execute routines as I wish using the "Call" statements in MySQL, is there a way stop this happening?
How to create database using knex npm?
Here it is MYSQL query
create database 'test'
I want to convert this query using knex.
There is no special API for creating DB in knex, probably because knex usually connects to already created DB and to be honest database creation is pretty rare operation.
Npm package knex-db-manager (https://vincit.github.io/knex-db-manager/) can do also database maintenance tasks and has separate superuser and normal user connection.
How can I migrate mysql tables to an already existing sql database.I have tried using sql server migration assistant for mysql tool, but it migrates entire database to a new database in sql server.Is it possible to transfer mysql tables to existing sql database?
Please help
If you have MySQL workbench and you only need the table structures you can select the tables that you need then:
Right Click > Copy to clipboard > Create Statement
Then past these into your new database an excecute
you can create a linked server the target system; this way you can import the tables selecting the data into the new tables on sql server.
if you already have the DDL migrated then you can fill the tables otherwise you can create the tables while copying the data.
with little scripting you can have the SQL code needed to copy the data ready in minutes.
there are many SO posts about interacting with MySQL from SQL-Server:
Can't create linked server - sql server and mysql
SELECT * FROM Linked MySQL server
Do I have to use OpenQuery to query a MySQL Linked Server from SQL Server?
Have you tried the Import/Export Wizard from within SQL Server Management Studio - it's essentially SSIS (an ETL tool) behind the scenes. It allows you to select specific objects, do transforms and such. I'd expect you'd be able to use a standard ODBC driver.
MSSQLTips has an article that seems relevant:

I have a MS SQL 2008 server with a database and need to create a table in MYSQL from a table/data in MS SQL. The mysql database has been linked and I have full access to the database. Can I do this using openquery?
OPENQUERY doesn't let you run DDL statements against remote databases. To the best of my knowledge, MySQL doesn't have an equivalent method of interacting with other RDBMS's.
You can however do this from SQL Server using the Import/Export Wizard to copy your table to MySQL. You may need to install MyOleDB or a similar driver to connect to MySQL.

I have been working on this all day and now I'm stuck, so hopefully someone out there can help me :)
The challenge.
Migrate data from MS SQL to MySQL.
The MS SQL I received as a bak file, which I restored using SQL server management studio on a PC with Windows 7 Home edition.
I have created a source MySQL database on a webserver, running LAMP.
The solution (maybe)
I'm currently trying to convert the database, initially just one table for testing, using MySQL Workbench with the database->migrate wizard, but now I'm stuck at the Bulk Data Transfer. I would expect this step to create the table in my MySQL database and transfer the data, but that never happens.
For the source I choose Connection Method = ODBC (native)
No problems connecting to the source and destination databases
I choose to keep schema info as table prefix, so imported tables look like: database.dbo_table_name
Migration step succeeds (migrate selected objects & Generate SQL Create Statements)
The Create statements look like this if I don't edit them
CREATE TABLE IF NOT EXISTS 'restored_database_name'.'dbo_table_name' … I think the 'restored_database_name' part causes a permission error. It does if I type this in the SQL tab directly in phpMyAdmin. Therefore I change it to:
CREATE TABLE IF NOT EXISTS 'dbo_table_name' …
Also per default this is part of the SQL:
DROP SCHEMA IF EXISTS 'restored_database_name';
CREATE SCHEMA IF NOT EXISTS 'restored_database_name …
I think this also causes some permission issues, so I commented these out.
In the next step I uncheck the 'Create schema in target RDBMS' since I don't think I want this.
The problem:
Nothing interesting for the next steps, but then at the "Bulk data Transfer" I get this error:
ERROR: 'restored_database_name'. 'dbo_database_name': mysql_stmt_prepare: SELECT command denied to user 'mysql_user_name'#host' for table 'dbo_database_table_name.
Finished copying 0 rows.
I think the error is somehow related to permissions on the destination database. I wonder if it is possible to make sql file, not just with the create table commands, but also with INSERT commands so I could just take the sql and import it using command line or phpmyadmin.
I'm using Workbench 5.2 CE
Any help is appreciated
I've seen that you have made your way into the Workbench's Migration Wizard. Maybe you're just missing something so I suggest you to review this blog so you can verify your steps: How-To: Guide to Database Migration from Microsoft SQL Server using MySQL Workbench.
Unfortunately you can't use the Migration Wizard data copy command line utility to generate the SQL file with all the inserts, but I'm pretty sure you can get this from MS SQL Server Management Studio and it should pretty much work for MySQL without modifications (or with minor modifications).
