Different Hosts, Different Schemas, Migration Help Needed (3 replies)

I need to transfer the contents of a schema on one host to a different schema on a second host. I do not have the option to create or rename a schema. All migration tools I have attempted will only export schema and all and attempt to create this database on the new host.

The one utility I've located so far that will transfer tables and data from old host to new host with different schema names is mysqldbcopy, however it returns an error that the source is running an old version. The version they are running is beyond my control.

Can anyone tell me what utility I can use and how to go about it?

Nvarchar- sql server to Varchar - mysq (2 replies)

I have been trying to use the migration toolkit in mysql workbench V6 to generate a schema from my sql server database. I am finding that for columns defined as nvarchar in sql server the toolkit generates a varchar column of twice the length in mysql even though the corresponding mysql column is utf8.

e.g a sqlserver NVARCHAR(255) is generating a VARCHAR(510) column in mysql. As the mysql column is utf8 this should only have a length of 255 matching the sqlserver column.

Please can you clarify whether my understanding is correct and that the column lengths generated are incorrect or provide an explanation for this?

Thanks

Dear All,

I migrated an MSSQL database to MYSQL using Workbench 6. I would like to be able to add more files without having to migrate the whole database again. Is there an option to add files? If I just select a single file in migration, then the MYSQL database is replaced with just that one file.

Thank you!

Cannot connect to MS SQL 2005 to begin migration process (1 reply)

Hello, I was hoping someone could help me. I'm attempting to migrate from MS SQL 2005 on a Windows Server 2003 machine to a new server with Centos 6.5 installed. I have MySQL installed, using MySQL Workbench 6.0 to begin the migration process.

On the Migration screen I've tried to use both FreeTDS and native drivers to begin the process of connecting to the source database, but I cannot get a connection when I go to test. I've tried following all the directions I could find online, set up a user DSN on the Windows machine ODBC, installed FreeTDS and unixODBC, attempted to install the Microsoft supported ODBC 1.0, and I just cannot get a connection to happen.

The error message that I cannot get past is:
Could not connect to Source DBMS.
[00000] [iODBC][Driver Manager]/usr/local/lib/libtdsodbc.so: cannot read file data: Is a directory (0) (SQLDriverConnect)

Any help would be appreciated, even if it is a quick "Look in this direction" message. Thanks!

The MySql Workbench Migration Wizard works great. Is there a was to schedule the command it generates ? Preferrably from cron (unix) but also from the Windows Task Scheduler ? (if not directly from the mysql workbench). if it can be done and you have an example, that would be very helpful ! thanks.

MySQL online database for 5 users (1 reply)

I created a pretty simple database that I'm planning to convert to MySQL using WorkBench. It has 1 Table and 2 Forms.

What I'm trying to do is have an online database that 5 users located in different cities can access and edit the database. All the data was to be stored in one table hosted on Microsoft 365, and the Front End (2 Forms) would be installed on each person's computer to be able to add information to the Table stored online.

I was going to use Microsoft Access database and split the database, but I don't want to pay Microsoft $10/month/user for this capability.

Is there a free or cheap (<$10/month) way to do this? I'm obviously brand new to MySQL and looking for a way to do this. I don't mind buying a harddrive to store it on at our office, but employees at our other location need to be able to work on it, which is why I was hosting it online to begin with.

Migrating table from Oracle to MySQL fails on column not found, when this column does not exists (no replies)

I'm trying to populate MySQL table from Oracle. On GUI all is well. but when I take the script and try to run it as a batch it fails, on 'column not found in target table', when this column is not in the source or target.
Oracle source table:
CREATE TABLE "SYS_COUNTRY"
( "ID" NUMBER(10,0) NOT NULL ENABLE,
"ISO_CODE" VARCHAR2(6 CHAR) NOT NULL ENABLE,
"NAME" VARCHAR2(100 CHAR) NOT NULL ENABLE,
"CONTINENT_ID" NUMBER(10,0) NOT NULL ENABLE,
"GEO_SCRAPING_NAME" VARCHAR2(100 CHAR));

MySQL target table:
CREATE TABLE sys_country
(
id INT(10) NOT NULL,
iso_code VARCHAR(6) NOT NULL,
`name` VARCHAR(100) NOT NULL,
continent_id INT(10) NOT NULL,
geo_scraping_name VARCHAR(100)
)ENGINE=INNODB DEFAULT CHARSET=utf8;

Script:
WbCopy -sourceProfile=Oracle_rd_g8_integ1
-sourceGroup='Default group'
-targetProfile=mysql_rd_g8_cms_test
-targetGroup='Default group'
-targetTable=sys_country
-sourceTable=SYS_COUNTRY
-ignoreIdentityColumns=false
-deleteTarget=false
-continueOnError=false
;

command:
java -jar sqlworkbench.jar -script=WbCopy.src -logfile='/tmp/log.err'

error log:
...
2014-12-28 13:31 INFO Connected to: [Oracle], Database version: [Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production

2014-12-28 13:31 WARN Column COUNTRY_NAME not found in target table cms_test.sys_country. Ignoring mapping!

....

I tried adding -columns to my script, but it didn't help.
When I create an Oracle table with column name c_name instead of name, all is OK.

How to I move my data to MySQL without changing the Oracle table?

Kind Regards,
Nirit

Did I miss this in the documentation? Workbench clearly knows about views and stored procedures in my MS SQL DB, but when I went to migrate the DB it created commented code for those structures and did not migrate them. The syntax looks different from MS SQL to MySQL, but I thought Workbench would take care of that. There are too many 400+ of each to even think about doing these one-by-one. How can I migrate these?

I am attempting to migrate a sql server database to MySQL using the Migration tool.

During the reverse engineer step I am getting the following error stating
'NoneType' object has no attribute 'upper'

If I understand correctly - there is a datatype that is somehow not defined in MySQL we use in SQL Server that has an upper function.

But I don't understand how to move past this (unless something else is wrong).

Here is trace log....
