Binary Operation in PL/SQL

How do I do binary operations like or/and/xor in pl/sql? Are there any built-in libraries?

I believe NOT x = -x - 1So NOT 19 = -20andNOT -8 = 7Hope this helps,
T.

How do I create a binary file using PL/SQL

Hi
Can you help me with writing a binary file in PL/SQL? I like to load binary data from data file, process in database then write to a new binary file.
Thank you very much in advance.

DBMS_LOB won't help you write a BLOB to disk.
You need to an external procedure to do that. Eric K's java works great and he's helped me with his solution and probably about a thousand others.
Doing a search on this forum will yield many discussions on this often regurgitated topic.

Binary operations

Hi all,
Okay im not very familiar with much binary operations, so I need a little help. The problem that im having is the DAQ board im using has uses a 32 bit interface for digital I/O, and I need to be able to change lines 8-22, depending on the decimal number and base the user enters and have that binary be in inverted logic. For example if the user entered 486.6 with a step size of 0.05 the binary in regular logic would be 000000000 010011000000100 00000000 and in inverted logic 000000000 101100111111011 00000000 and I dont want the change of decimal affect any others lines of the code. I think maybe for that I could just set a max limit for the decimal number to being 2^15-1, but not sure I can create this limit and shift in the binary in labview. Any help would great, thanks.

dbartz,
Al of the logic primitives are polymorphic, meaning that you anc use them with numerical values. Set up your data as an unsigned 32 bit integer (U32). Use AND and OR functions to mask off the parts you want to change and the parts you want to protect. If you had 8-bit words (for a simplified example) and wanted to change bits 2, 3, and 4, you could do this:
let K = old data (example K = 10101010)
let P = new data (example P = 00111110) {Notice that P has non-zero values in bits other than 2, 3, 4}
let Mk = mask for old data (example Mk = 11100011), and
let Mp = mask for new data (example Mp = 00011100 = NOT Mk).
Then (K AND Mk) OR (P AND Mp) = data to write.
Using the example values above (K AND Mk) = 10100010, (P AND Mp) = 00011100, and data to write = 10111110.

Store a uploaded file of type binary into a java.sql.Blob

Hi all,
I try a File-Upload and store the file in a java.sql.Blob of a MaxDB.
My Problem is, that I'm not able to import a Model-Attribute of data type byte[]. Further I don't no how to convert the uploaded value attribute of data type binary, in a java.sql.Blob.

In range and coerce binary operation

How do I implment the "in range and coerce" function with binary operation? I want to do that to make my fpga code more efficient.
Kudos and Accepted as Solution are welcome!

What exactly do you mean by "binary operation"? I am assuming you are dealing with integers here to make life simple.
The In Range portion is just a simple Less Than and a More Than with an AND ( x < UL && x > LL). The Coerce portion would likely be best done with Select nodes based on the Less Than and the More Than comparisons.
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

RS-232 binary operation

Dear all,
I am a researcher with commercial instrument.
After communication with my technician, I got to know I have to do binary operation in RS-232.
But I am not familiar with the binary operation.
Could you please give me some solution about this by labview 6 or 7?
I attah a part of the manual.
*)please let me explain the meaning of the parameters.
Host → Ecotec II: 5(start the communication), 5(length of the command, 5 bits),
3 (RS-232 functional command), 0(parameter of the command), 13(checksum, 5+5+3+0).
Very thank you for your attention.
Any comments will be very helpful to me.

How can i do bitwise (binary) operations (AND, OR, XOR)

I need to do bitwise (binary) operations such as AND, OR, and XOR. For example, how do I AND 10101000 with 11111000?

for OR, with 10101000 in A1 and 11111000 in A2, try:
=1×SUBSTITUTE(A1+A2,2,1)
Result: 11111000
and for XOR, try:
=1×SUBSTITUTE(A1+A2,2,0)
Result: 1010000 (missing leading 0)
You can display missing leading zeros by setting the cell's Data Format to 'Numeral System' with Base set to 10 and Places to 8, or turn the result into a string with something like this (assuming the result is in A3):
=RIGHT("0000000"&A3,8)

Binary operations in Java

Hi,
are there any binary operations in Java like '&' in C? I didn't found any information in the API description.
Thank u.

You didn't find them from the API since they are a feature of the language. Try the langspec instead: http://java.sun.com/docs/books/jls/second_edition/html/expressions.doc.html#5228

How to use/implement xor binary operator in oracle

Hi,
Like in VB and .Net we have a Binary operator/expression called Xor for the following
logic....
EXAMPLE:
A Integer = 10
B Integer = 8
C Integer
c = (A Xor B) OUTPUT is 2
1010 (10 in Binary)
1000 (8 in binary)
0010 (result is 2 in binary)
I want to implement the same logic in Oracle do we have any builtin operator function
for this? If we dont have can anyone please try to code it. It will be very helpful and
urgent.
Thanks in Advance
Reddy

do we have any builtin operator functionfor this?
Up to a point. Specifically, Oracle has a BITAND() function. With this it is possible to code our own BITOR and BITXOR functions. I'm glad to say I personally haven't had to worry about bits for over ten years, but Connor McDonald has posted a solution on Jonathan Lewis's FAQ site.
Cheers, APC

Spamtrainer error - binary operator expected

Notify more than 1 operator in a SQL Agent job

Hi Forum,
is there a way to notify more than one operator if a SQL Agent job fails?
TIA
Alex

Hello Alex,
If you are using a "maintenance plan" task "Notify operator" you can select several operators from a list.
In a SQL Server Agent job itself you can only add several operator for "warnings", but for the notifications like "finished" just one.

Performance: Operations in Cursor vs. Operations in PL/SQL block

Why does I have a better performance when I program operations in complex cursors instead of programming the same statement in a pl/sql block in a stored procedure?
Operation in a Cursor:
CURSOR c IS
DECODE(name,'Peter','dog','cat') animal
...The same Operation in a PL/SQL block:
begin
if name = 'Peter'
then
animal = 'dog';
else
animal = 'cat';
end if;
end;
...I know that a parsed cursor is placed in the Shared Pool and reference
a context area in the PGA.
Does anybody have an idea?

Maybe because if you can write only a SQL query, it is faster than to write PL/SQL code that will do the same job. See following thread for a analog discussion: Re: pl/sql table

Logical XOR operator in T-SQL (SQL Server 2000)

Hi all....
I was wondering why SQL Server 2000 lacks a logical XOR operator. Do you have a ready to use function that implements it?
How can I program one by myself? I know that A XOR B is equivalent to NOT A * B + A * NOT B. So I tried to create this function :
CREATE FUNCTION XOR
-- Add the parameters for the function here
@A BIT,
@B BIT
RETURNS BIT
AS
BEGIN
RETURN NOT @A AND @B OR @A + NOT @B
END
But it didn't compile.
How can I pass boolean values as parameters? any other hint?
Thanks
Jaime

I have these two views , one of them hard coded as NULL as it always needs to be NULL. I wanted to union them
Now the problem is I have to replace those NULLS if I have a value from other VIEW or else NULL ( no change)
I am getting duplicates of rows with values and NULLS , whereas I needed only records with values
I need records with values and records without value as NULL . please let me know how to eliminate dups with NULLS
