Logical operator in datatemplate query

• Logical operations on a string of bits

  Hi, I have a very simple question that I can't seem to understand.  I'd just like to perform logical operations (AND, GOLD, etc.) on 2 strings of bits that are 24 bits long each, however I can't find in the palette of functions a function that acts as a binary constant.  I see that constant digital and hex functions.  You can somone please let me know where I can find it.  For example, I would AND ' 111111111111111111111111 '& ' 000000000000000000000000'.

  You know the difference between numeric and string data types in LabVIEW? Blue = digital = integer. Pink = string. In the example you linked to, they use an integer constant when the display format is set to "binary". The 'b' of the constant indicates the radix, which in this case is 'binary '. Right-click on a digital constant and you can change its display format. You can select one of the predefined formats or you can specify a by clicking on the option "Advanced Editing Mode. Eligible formats are defined by using LabVIEW. For example

  %b = binary

  % 8 b = binary, using the width of minimum field of 8, fills spaces (for example, '1101')

  % 08 = binary, using 8 minimum field width, filled with zeros (for example, "00001101")

  To be called from instructions SQL, stored function must obey "purity" following rules, which are intended to control the side effects:

  • rule1) When it is called from a SELECT statement or a parallelized INSERT , UPDATE , or DELETE statement, the function cannot change database tables.
  • rule2) When it is called from a INSERT , UPDATE , or DELETE statement, the function cannot query or modify database tables modified by that statement.

  Can you please explain this? I think that these statements are contradicted with

  insert into select double function_a table_2

  Now, I make the same mistake. It is to insert records into table_2

  When your function is called by a select statement, an error is triggered because of rule1).

  When your function is called in an insert statement, no error is raised. The insert does not work in parallel (this is an insert row after all). So rule1) is also not infringed. The insert is on the table2, change table1. Because it does not modify the same table rule2) is not violated. So no reason to trigger an error.

  from tab;
  
  select col1 ,order_by,case when col1 <> 10 then 0 else 1 end

• Boolean logical operation

  Hello! Recently, at work, I was responsible for creating the code that returns something on two Boolean State. Something like: If Boolean has and Boolean B, return if Boolean is and B no Boolean etc something else.

  At first I thought that the best way to do it would be a formula node with the return value is passed through a bunch of if else statements. Then I discovered that Booleans are not supported in notes formulas and forms knots are designed for writing formulas, and not for current programming, that makes sense.

  I came with two ways to do it, but I felt that they were both quite stocky and they suck if I had more than 2 Boolean values my logic on the basis. Here is the code with the two different methods.

  

  I feel like this is an operation that would be much better to do it in an if else statement in code and I would like to know if there is a better way to do this in LabVIEW.

  Typical in LabVIEW is to combine Boolean both in a table, then use of the boolean to number table. This will give you a value between 0 and 3 (included). You can use a single case statement, or you can create a table of values of output desired and use it as an index in the table, or if there is a direct mapping of the enum, you can simply convert that number to the enumeration type.

• String separated by commas to 'IN' operator in SQL query

  Hello

  The issue is that the "In" operator in the report query accepts values contained in the element of page Apex... 221,332,542.

  Is there a common solution for this problem?

  Thank you

  It's the common "variable list" model [anti-]. In

  select * from table where columnvalue in (7788, 7839, 7876)
  

  (7788, 7839, 7876)is a list of expressions and the predicate is evaluated as a membership condition.

  In

  select * from table where columnvalue in :P1_X
  

  :P1_Xis a scalar string, unable to contain multiple values.

  In a report of type APEX, a source report of the body of the PL/SQL function returning a SQL query with lexical substitution can be used to produce a "variable list:

  return 'select * from table where columnvalue in (' || :P1_X || ')';
  

  where P1_X contains less than 1000 values, has been disinfected to code SQL injectionand string values are properly cited.

  Some people suggest the following approach, that will work also in interactive APEX reports:

  select * from table where instr(':' || :P1_X || ':', ':' || columnvalue || ':') > 0
  

  However, it is underperforming because it eliminates the possibility of using the index optimizer or the size of the partition in the execution plan.
