android - How to access one class database in another class? -

-

I created a database in my class like 
  public final string CRAZY_ALARM_DB_NAME = "CrazyDb"  
 ; Public end string CRAZY_ALARM_TABLE_NAME = "CrazyTable"; Alarm db = this.openOrCreateDatabase (CRAZY_ALARM_DB_NAME, MODE_PRIVATE, empty); Alarm DB.XACSQL ("if not present on table" + + CRAZY_ALARM_TABLE_NAME + "(REQ_CODE INT (3), day INT (3), HOOR INT (3)" + ", minute INT (3), COUNT INT (3) , Repetition INT (3) "+", day VARCHAR2 (100), SNINT (3), Mon INT (3), "+" TEENT (3), with int (3), ThuUnt (3), FRI INT 3), "+" set INT (3));); Cr = alarmDB.rawQuery ("SELECT * FROM" + CRAZY_ALARM_TABLE_NAME, empty);   
 So I want to use this database in another category. I am also doing the same thing, I wrote the code "OpenOffrrr" in another class and in the "cursor". But while compiling it on the cursor line ... there was no such table.  
 Please help me   
 
 
 The better you can, it's a database assistant, where you can make all these calls And which can be available and accessible from all your activities.  
 In addition to this, you should remove and install your app again to be able to create a table. I have this problem at any time.

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...

memcached - Django cache performance -

-
We are now using Redis for in-memory cache for our Django application (we used the first memcatch The difference in performance is no big, and we're using Redis because the disc dump feature). The problem is that Django cache's performance in my view - terrible, we have a view with 102 cache hits (no miss), and it has 81 ms (only the cash part, which is with the DJBugBug toolbar Is measured). In my opinion - this is a very long time, I know, asking for a question for DB can be 10x more (or 100x) time, but that is also not good with cash performance of that fact. We are running radis (and the first memacatch) on different hosts, connected to the local network with other servers. Is there a way to maximize cache performance in Django? Instead of displaying problem cache, there is a possibility of the number of items to be received for each page 102 Cash calls mean long time lost due to network latency. With full control of the code, you may be able to fix it with m...
