In my symfony project i need to generate schema from specific tables not all database tables ,so please tell the way to do if it is possible?
If you use the command build-schema you can generate a schema from the database that is configured for the project. The schema.yml in the config folder should contain all the tables, and you can delete the tables you do not need, and then use the commands build-model, build-form, and build-filters in order to create the classes for the remaining tables. This way, there will only be classes for the tables that you want.
Hope this helps!

I am running the update-database command in VS to create tables in a DB for a project developed by someone else. For some reason, when i run the command, all the tables are prefixed with my domain\username. The same also happens for one of my collegues, meaning we now have two sets of tables! Any idea how we stop this happening?
This happens on when you are not a database owner and the object names are not schema-qualified. So either run the migration as a database owner, or specify a schema in the model configuration to force all the objects into the dbo schema.
I'd like to copy a schema to a newly created one in Oracle Database, in Oracle Cloud.
As far as I know, these databases are managed ones, so I can't run expdb / impdb on them.
Any other idea how to copy (~clone) an entire schema?
Thanks,
As #dmitry shared above-
1.Extract DDL stackoverflow.com/questions/10886450/…. 2.Extract data csv github.com/dmitrydemin1973/powershell-oracle/blob/master/… or insert sql. 3. Create tables in cloud. 4 Load data into tables(sqlloader or sqlplus). 5Create other objects(indexes, procedures, packages,etc ).6 Recompile functions, procedures, packages, views.
Please see #dmitrys response above
everyone. I use Symfony 4.2 and following database-first approach and have auto-generated entities; But then I need to do some changes in field definitions in entities but I don't want to affect the database structure. Everything works well but if I try to create a migration, doctrine includes all the differences in migrations, and I find no way to prevent this behaviour. I've tried schema_filter: ~^migration_versions$~ but somehow it doesn't help.
So the questions:
1) is it a normal application state on prod when column definitions slightly differ in database and entities?
2) how can I say to doctrine to ignore differences in some tables when creating migrations? Thanks.
When you run bin/console doctrine:migrations:diff it will generate a file in your src\Migrations\ directory. You can edit the generated file to remove whatever you don't want to change before you run bin/console doctrine:migrations:migrate.
I don't suggest doing this on a production server though, and especially if you do so then you should certainly have a backup of your database.
Is there a way to make Entity Framework 4.1 Code First NOT to drop database or the tables, not even if its changed? Im suppose to upgrade a LIVE site and I cant because of this. I seen some NuGet classes I can get but its to not drop database but tables, recreate tables on change ect.. i just do not want to do anything to the database or the tables.
In the startup of your application add this:
Database.SetInitializer<YourContextType>(null);
This should remove any initialization strategy.
I am new to spring-iBatis. I have a requirement to create a database dynamically from my application. The database is MySql. I have seen that there are methods for insert,update and delete like SQLMap.insert(). but I am not finding any method to execute Create statement. Can anyone help me ?
Try using Abator to assist in your code generation.
Hibernate can create a schema for you, because it takes information from objects and mappings and creates tables for you.
iBatis doesn't have the information about tables from mappings; you give it SQL to work with tables that are presumed to exist.
I'd recommend that you add SQL CREATE TABLE statements to a script and execute it with MySQL to create your schema. It should be complete by the time you start with Java and iBatis.
