I have generated Entities files, Proxies files and Tables/fields in database via .yml file schema. I would like to add one more field in schema file.
How can I regenerate Entities, Proxies and MySQL tables/fields via command line tool without dropping tables and deleting all records?
I tried with these and does not work (I am getting error):
./doctrine orm:schema-tool:create
./doctrine orm:schema:tool:update
What did I miss?
I have found a solution:
With this command orm:schema-tool:update --force you add/remove/update fields in database without dropping all records. But firstly you need to change YAML file and Entity class.

I'm using Sequel::Model. My model has a set_schema block and a create_table call, so the database is completely managed by the model. The database is sqlite.
I'm trying to add columns to the database and I can't find a way to. Adding fields to the schema has no effect. Adding a migration or an alter_table call doesn't do anything. I've asked on IRC and read the docs. I can't find an example of anyone doing this, but it seems simple.
How do I add a column/field to a Sequel Model?
I did a bunch of research and talked to Jeremy Evans. I was going about this wrong. The right way to do this was to remove my schema plugin code and create_table block and move to using migrations. The steps I went through were:
Remove the schema code (create_table, set_schema) from my modesl
Dump the schema from my current sqlite data files into initial migrations into migration files via the sequel -d command
Create a new migration that adds the columns I need via add_column calls in an alter_table block in a change block
Apply the migrations via the sequel -m command
Create rake tasks to run the migrations and hook those tasks into my deploy tasks
As you know, parse.com will be closed.
I made export of all collections.
Now i have the many dumps of collections.
Collections name like:
_User
AppParentCompany
It's normal tables name, but between this files i have relations, a relation contained in the next file:
_Join:parentCompanies:_User.json
Latest file name i understand like:
_Join - is relations
parentCompany - it's column
_User - a collection containing parentCompany column
Based on this, i have next questions:
How i can import this relations into a database?
What name will be for this collection of relation?
Thanks!
Take a look at this page: https://github.com/ParsePlatform/parse-server/wiki/Migrating-an-Existing-Parse-App
Prepare mongodb database connection string first.
Go to Parse your project's App Settings > General.
Find App Management > Migrate to external database. Press Migrate button.
Enter your database connection string, it will start with mongodb://...
Then press Begin the migration.
Then Parse will do the rest for you.
P.S. If you are using mongolab, go the web browser, into your database, then you can find _Join:xxx:xxx, _SCHEMA and more in Collections.
I'm creating a database project is VS2013. I am manually building up the database as and when the objects are required (it's basically a gradual copy from an existing database). I have done imports to a database project from an actual database and I'm trying to follow the same project structure (i.e. [Schema Name Folder] > [Tables Folder] > [Actual Table Script File]).
The issue I am having is that when I add a new table, regardless of where in the project tree, it will use the default dbo schema and the only way I can change the schema of a given object is to change the T-SQL of the table's script file which is a slow and error-prone solution. This is even worse if you include the 'Include schema name in file name' option in the database properties as you would have to rename each object you create.
I must be missing something here, is there a way to create an object in a specific schema?
I've a previously created DB with sfDoctrineGuard tables and also two more tables: almunos and socios. I'm trying to run the task
symfony doctrine:build-schema
and aparently seems to work but surprise only the tables related to sfDoctrineGuard plugin appears and not the others two. Why? Did I miss something? What I'm doing wrong?
As the task description says:
The doctrine:build-schema task introspects a database to create a
schema:
./symfony doctrine:build-schema
The task creates a yml file in config/doctrine.
So you have to look inside the folder config/doctrine to check the generated schema.yml.
I am currently trying to setup an ASP.Net MVC 3 Application for the first time. I know what I am doing with Ruby on Rails but completely lost with ASP.Net. I would like the app to create the database but not sure what I am doing wrong. I have an empty Database build called ssDB. I have setup the connectionStrings and built out the Model classes. According to everything I have read thus for, when I go to the run the App it should create the database but it doesn't look that way.
The Abbreviated Error I get is:
InnerException: System.Data.SqlClient.SqlException
Message=Invalid object name 'dbo.Users'.
Source=.Net SqlClient Data Provider
ErrorCode=-2146232060
Class=16

I have an empty Database build called ssDB
You have created an empty database with no tables. Since there is a database EF assumes tables are also created. Hence it will not proceed to create the tables.
You can drop the database and allow EF to create the database and the tables.
I also experienced the same issue while using Database first approach. Connection string in my service's/service's host web.config was incorrect. I corrected the connection string and it worked.
