c# - Large entity framework split into many EDMX. How to operate between those? -

-

I am working on a large database, it will contain a total of 200-300 tables. First of all, does anyone have such database in an EDMX? In the designer of my experience, when you get 50 or more institutions, it becomes useless.

In my case, the database itself divides itself, such as in the subject areas like Membership, Systems, Assets etc. > This is the same with ADMX and everything works more or less well.

There is every problem that I can bet .. I have all the main institutions, and the user table lives in different EDMX.

I can deal with this fine for the operation of the CUD because I have hanged around the current user but for retirement, I often need to display that ID which was created and for this I must be involved together. But I can not be included in the table in different EDMX.

I get 2 solutions on this:

  1. I can not list the users' list (it can not be too large) and

  3. I know what I am doing - # 1 is probably okay but I can see how I can be in the future to be involved in various models And you will be surprised how do you handle it?

    itemprop = "text">

    edmx only defines a conceptual model of your database, then it is ok to add user tables to many ADMX files

    Option # 2 is OK.

    You need to have different names for tables, which are repeated in many ADMX files to avoid conflict. Some users, such as SystemUser, AssetUser, actually point to the same table.

    Thank you.

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

Oh, for the moment I am not sure how it is officially supported, but for the success of the people Using Monodroid Vic Cool Storage I am able to leave and compile assemblies in my project, but while trying to use some classes, the errors of time have to be gathered. Especially when trying to connect like the example for Mono Touch string dbName = path. Cobain (environment. Gatefolder path (environment specialfolder personal), "mydb.db3"); // The following line will be called coolestation, where is the database, // to make it if it does not exist, and call a delegate that creates the necessary tables (only when the database file was newly created //) CSConfig.SetDB (DbName, true, () => {CSDatabase.ExecuteNonQuery ("Subscriber Integer Primary Key Attribute, Name Text (50) No, Number, Date First Text (30)");); There is no difference when I try to use the methods of CSConfig and when I cscfif If I try to pass 3 aggregates to STDB (3) then I get the invalid ...

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
