database - Xcode: SQLite in embedded method -

-

I'm working here with a new problem I started with the following code: 

 < Code> - (IBAction) Login: (ID) Sender {const char * dbpath = [databasePath UTF8String]; Sqlite3_stmt * statement; If (sqlite3_open (dbpath, and contactDB) == SQLITE_OK) {NSString * querySQL = [NSString stringWithFormat: @ "where contacts SELECT * login = (\"% @ \ ") and p = (\"% @ \ " ) ", Login. Text, password. Text]; Const char * query_stmt = [querySQL UTF 8 string]; If (sqlite3_prepare_v2 (contact DB, Kweri_stimti, -1, and statements, zero) == SQLITE_OK) {if (sqlite3_step (Statement) == SQLITE_ROW) {// store '1' when a user wants to log in to be in the ** If (LogSwitch.on) {[auto aStayLogged]; } And {[a resale ged]; } ** Model * Model = [Model Sharing Model]; Model.paramLogged = Login.Text; // [self disclosedsection view: zero]; } Else {status.text = @ "Login failed: Please check your ID and password"; } Sqlite3_finalize (statement); } Sqlite3_close (Contact DB); }} - (zero) aStayLogged {sqlite3_stmt * statement; Const char * dbpath = [databasePath UTF8String]; If (Sqlite3_open (Dbpath, and contactDB) == SQLITE_OK) {NSString * updateSQL = [NSString stringWithFormat: @ "Update contacts logged off = '1' where login = (\"% @ \ ")", English . Text] ; Const char * update_stmt = [updateSQL UTF 8 string]; Sqlite3_prepare_v2 (contactDB, update_stmt, -1, and statement, NULL); Full success = sqlite3_step (statement); If (success == SQLITE_ERROR) {// NSAssert1 (0, @ "error: message failed to enter database with '% s.), Sqlite3_errmsg (contactDB)); status.text = @" Update failed " ;} Else {** Status.text = @ "OK Stay"; **} // sqlite3_bind_text (Statement, 1, [Cofinam UTF-8 string], -1, Skyueltiutiaraansaiaisaiti); // sqlite3_bind_int (details, 2, Cofiaidi) ; Sqlite3_finalize;} Sqlite3_close (Contact DB);}   
 This is a deal: If I link to 'aStayLogged' method as IBAction for a button, then update Is done properly But when I embed this method in the 'method' method, then nothing happens!  
 I check it by law:  
  - (IBAction) Check {sqlite3_stmt * statement; Const char * dbpath = [databasePath UTF8String]; if (sqlite3_open (dbpath, and contactDB) == SQLITE_OK) {NSString * querySQL = [NSString stringWithFormat: @ "log where these contacts = '1' "]; Const char * query_stmt = [querySQL UTF 8 string]; Sqlite3_prepare_v2 (contactDB, query_stmt, -1, and statement, NULL); If (Sqlite3_step (statement) == SQLITE_ROW) {NSString * logField = [[NSString alloc] initWithUTF8 string (Const char *) sqlite3_column_text (say, 0)]; Status.text = loggedField; [Logfile release]; } Else {status.text = @ "Update failed"; } Sqlite3_finalize (statement); } Sqlite3_close (Contact DB); }   
 This funny thing is that the situation changes in "stay fit" which is a confirmation that he should have worked! Does anyone know what can be the reason for this? Sorry for a long time - I have to ask stupid questions, but this time I do not really see it ...   
 
 
 hm, I think that you have mis-used to check with SQLITE_ERROR because many other status codes which do not meet, you are checking on better SQLITE_OK or SQLITE_ROW, and if you want to do this The status code you have is' rectified.  
 If you are mistaken then there is an error compared to using  sqlite3_errmsg  to find out I think maybe there is something with SQLITE_BUSY or lock

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.

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...
