sql server - Change datatable and tableadapter schema at runtime according to stored procedure. C# -

-

I have a dataset and table adapters for the table in that dataset. The problem is that to fill TableAdapter DataTable Uses the stored procedure, but the amount of returned column may vary. How can I change the datatylet's schema on runtime to get all the columns from the stored procedure?

In my opinion, leave the idea of ​​using a data adapter, it is completely unnecessary Do this instead to get DataTable: 

 using  (SqlConnection con = new SqlConnection ("Conectionstring")) {con.Open (); (Using SqlCommand commnand = new SqlCommand ("StoredProcName", con)) {command.CommandType = CommandType.StoredProcedure; SqlDataReader Reader = command.ExecuteReader (); Datatyal table = new datatelle (); Table.Load (reader); Return table; }}   
 It is no longer a matter that you return the call to the call #, all of them will be included in the dataet  
 edit:  & Lt; Configuration & gt; Move the actual connection to your connection to the following section in your Web.config file under the  section. You should be able to copy it from your settings file.  
 
  
 And now create your SqlConnection as follows:  
  SqlConnection con = new SqlConnection (Connection Connection ["ConnectionString"]. ConnectionString ))   
 Note that "ConnectionString" is the name attribute of the connection string in Web.Config.  
 In the second case, it is not clear.

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...

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...
