javascript - is - select * from empty table possible? -


On my website I'm trying to select 2 tables - from which tableB can be empty, so this is someone Also, the result is not returning when the tableB is empty I hope I understand it properly. Any suggestions? 

  curatio.webdb.getAllTodoItems = function (renderFunc) {var db = curatio.webdb.db; Db.transaction (function (tx) {tx.executeSql ("Select * to Table A, Table B", [], RenderFunk, Quiteo.wbb.bt.;}); }

Basically the example in the table is the name and aliases column and the example in TableB is the address of the address. But sometimes there is no address, and then I can not find anything to display.

I basically need to ignore the tablebars if it is empty.

Although your query does not point to it, I still think that you might possibly Looking for, because I'm assuming that you want to add data from two tables with the same value, one column from table B (which is known as the foreign key).

This query selects the values ​​of the first table, even if it contains no matching data in the table: 

  Again, it assumes that you mean That means that you mean, `` `` `` `` `` `` `` `` `` `` `` `` `for example:  
  Person (Table A): - ID - Name Phone Number (Table B): - id - person_id // This is a foreign key Table A which is the "link" data - PhoneMan  
 
 If you regularly use  JOIN  (also known as  INNER JOIN < / Code>) Then only the rows are returned for the data that matches between the two rows. 
 
 What was your original query, however, (both ways) while editing your question, I hardly think that it was really after you.

I am using Objective-class in my Swift Project through a bridging header. The method signature looks like this: - Some cement (some type) some parameters; I started by getting an example of class, calling method, and storing the value: var myInstance = MyClassWithThatMethod (); Var cfArr = myInstance.someMethod (some value); Then try to get the value in the array: var valueInArrayThatIWant = CFArrayGetValueAtIndex (cfArr, 0); However, I get the error unmanaged & lt; Cfarray & gt; Not like 'CFArray' . Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
