I have created my database and tables in a SQL Server Express database. And now I migrated the database tables to Oracle with Entity Framework. But my tables are empty in Oracle. How can I move my data to Oracle?
Use SSIS interface from MS-SQL (Sql Server Integration Service).
I have used to move content from MSSQL to MySQL you should use the correct odbc driver.
For express edition, You can use Linked Servers to establish connection between SQL Server and Oracle. In this way, you should insert the records by creating queries for per table.

Currently I am trying to migrate from mysql to Microsoft SQL Server. For this I have transferred the entire database from mysql to SQL Server and did some modification in the SQL Server database structure. Now I want to transfer only data from my mysql database to the SQL Server database.
I am using SQL Server 2019. Do you have any solution for this?
Thanks in advance.
I have tried to find a solution for this but didn't find any to transfer only data.
We have databases like oracle, sql server, postgres and looking to synch the data like full/delta load into one database. Can you suggest some tool to do this.
Yes, SSMA can do that.
Migration Sources allowed are:
SQL Server Migration Assistant for Access
SQL Server Migration Assistant for DB2
SQL Server Migration Assistant for MySQL
SQL Server Migration Assistant for Oracle
SQL Server Migration Assistant for SAP ASE
But the destination will always be SQL Server.
Once your databases are all SQL Server I suggest you to merge them all together dividing them by schema.
Is a very primitive way to work but is the only I know.
I have an SQL Server installed on a local Windows 10 machine - I'm using Microsoft SQL Server Management Studio to interact with it.
I also have a DB2 database hosted on an IBM i machine and I've created a Linked Server in SQL Server Management Studio to represent it. I can connect to the Linked Server and can query/pull data from it successfully.
I'm trying to copy particular tables from the Linked Server and insert them into a Database/Schema in the SQL Server - I can do this successfully but unfortunately, it appears that in the process of copying the table over, none of the constraints (particularly in my case, the key constraints) are maintained.
Is there a simple way to copy over tables from a Linked Server to SQL Server (in SQL Server Management Studio) while maintaining key constraints?
The following query is an example of what I'm using to copy the tables over (one-by-one):
SELECT *
INTO SQLSCHEMA.SQLTABLE
FROM LINKSERVER.LINKDATABASE.LINKSCHEMA.LINKTABLE
The easiest way is to use proper tool for it like SSMA:
Microsoft SQL Server Migration Assistant (SSMA) is a tool designed to automate database migration to SQL Server from Microsoft Access, DB2, MySQL, Oracle, and SAP ASE.
Migrating DB2 Databases to SQL Server (DB2ToSQL)
SQL Server Migration Assistant (SSMA) for DB2 is a comprehensive environment that helps you quickly migrate DB2 databases to SQL Server or Azure SQL DB. By using SSMA for DB2, you can review database objects and data, assess databases for migration, migrate database objects to SQL Server or Azure SQL DB, and then migrate data to SQL Server or Azure SQL DB. Note that you cannot migrate SYS and SYSTEM DB2 schemas.
I have a problem: I have a SQL Server database, and another in Oracle; these databases have the same structure, DDL, same table, same indexes and so on.
The tables in the Oracle database are empty and I need to migrate just the data stored in SQL Server to the Oracle database.
Is there a tool in SQL Server or in Oracle that will help me do that? Or a someway to do it ?
Can you please help me?
Have a tool in SQL Developer called "Migrate to Oracle" where by it To migrate data from SQL Server to Oracle
I have a project with a SQL Server Express database and Entity Framework migrations. But I need to migrate my SQL Server Express database to Oracle. But Oracle database has existing tables. How can I migrate to Oracle?
If I set Oracle connection strings and run a command update-database in package manager console, will existing database tables be deleted? Or what is the best way?
Funny question does the Oracle db tables have data stored?
