python - alembic and getting the last inserted value -

-

I am using Alembic to manage my database structure.

And the primary key ID column will be an autoincrement-column. How do I ask the data in the upgrade script, so I'm sure I got the correct ID (I know that this is 1 in this specific case)?

I know how 

  #creating table op.create_table ('srv_feed_return_type', sa.Column ('id', sa.Integer, primary_key = true), Sa.Column ('name', sa.String (50), null = false), bit column ('created', bit datetime, server_default = funny. Now (), faucet = incorrect), bit column ('created ('LAST_UPDATED', sa.DateTime, False = false), sa.Column ('last_updated_by', sa.String (50), faucet = false), ' For operation) # Table srv_feed_return_type = Table ('srv_feed_return_type', column ('name'), column ('created'), column ('created_by'), position ('LAST_UPDATED'), column ('last_updated_by')) #bulk insert op.bulk_insert (srv_feed_return_type, [{'name': 'dataset', 'created': datetime.now (), 'created_by': 'Asken' , 'Last_updated': datetime.now (), 'last_updated_by': 'Asken'}]   
 I know that I can update but how can I seal down the whistle Using something like that?  
  op.execute (srv_feed_return_type.update (). \ Where (srv_feed_return_type.c.name == op.inline_literal ('dataset')). \ Values ​​({'name': op. Inline_literal ('someelse')}  
  
 
 
 To pass the sequence for the key column, the changes to the table schema definition will be required:  sa.Column ('id', sa.Integer, sequence ('srv_feed_r_t_seq'), primary_key = true),   
  #creating table op.create_table ('srv_feed_return_type', sa.Column ('id', sa.Integer, sequence ('srv_feed_r_t_seq', primary_key = true), bit column ('Name', SA string (50), Nabel = Fell), a column. ('Created', a bit time, server_default = funny.Now (), faucet = incorrect), a column ('created_by' , Sa.String (50), False = false), sa.Column ('LAST_UPDATED', sa.DateTime, False = false), sa.Column ('last_updated_by', sa.String (50), faucet = false))   
 Now about how to get the ID:  
  op.execute  and  op.bulk_inert  you No results returned. But you can use the same connection for these actions. After  
  bulk_insert  or  execute (table.update ...)  you can choose which queries can run and records of interest in the same context Retrieve the PK ID for:  
  connection = op.get_bind () r = connection.execute (srv_feed_return_type.select (). Where (...)) for row in R : Pk_id = r ['id'] "" "or some more sophisticated" ""   
 You must specify the appropriate filter where the clause is to ensure that you record the identification Recent unique The altered.  
 Here, but the selected questions have made it difficult

excel vba - How to delete Solver(SOLVER.XLAM) code -

-
After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'

I have a UITextView and I change a word like the code at the end of UITextView.text: - (void) Replace TexttechWitWord: (NSString *) word {NSString * currentTextViewText = self.textView.text; CurrentTextViewText = [currentTextViewText stringByReplacingCharactersInRange: NSMakeRange ([self.textView.text length] - [word length], [word length]) withString: word; Self.textView.text = currentTextViewText; } Replacement work is fine, but it runs very slowly and very slowly when the textView now lengthens Is there any better way? I try the replacement range: with text for a week but still stuck. Not to know how to use it to replace it in your case. Please guide! Thanks in advance! This is an important job. As you are using an irreversible string and you are creating a very long string and before Assigned to NSString created from.
