Write a uniqueIdentifier in SQL DB
Hi, I have a SQL database with multiple tables. The tables are linked each other by ID. The type of the ID is of type UNIQUEIDENTIFIER. I should read the ID of the first array and write the same ID in the second table. Ando so now for each table.
I use LV Database Toolkit and I already did the reading of the ID: 5240A2A6-9453-E011-80CD-406186EDCDB2. In BT, the ID is a Variant, but when I try to write a different value in the 2nd table is written: 02802108-0000-0100-0006-008400010001.
What type of data is the uniqueidentifier in LV? What is a Variant?
Thanks for the support.
Hi, I solved the problem by implementing a StoredProcedure in SQL database. I call the stored procedure in labview and I pass the uniqueidentifier as string.
Thank you Alex.

Need help to write to Oracle and SQL Server in the Oracle triggering
We have a third which feeds data for us. Their client application feeds directly to some source tables in our Oracle database 10g. We have triggers on those tables that sort and treat lines as they come.
We have a new operation and try to write some of these incoming data now to a SQL Server database through heterogeneous services - essentially the same exact data in two databases. I have a related database that works very well for the selection, but I've never tried to write Oracle PL/SQL to write in a DB SQL Server 2008. My first attempt was met with the following error: "ORA-02047: impossible to join the current distributed transaction.
I found another thread where they say that the only way to do it is by using a stand-alone transaction, but they do not give an example. Here is the section of relaxation that I use:
Can someone point me to a way to accomplish this simple insertion?select to_char(new_date,'MM-DD-YYYY') into sql_txt from dual; insert into mancamp_location@sqlweb ("UnitID", "ManCampID", "Lat", "Long", "UpdateDT", "VehSpeed", "VehDirection", "Landmark") values (v_truck, f_unit, f_lat, f_long, sql_txt, f_spd, f_dir, f_ldmk);An example of a standalone trigger is:
Suppose you have a table in Oracle:
CREATE TABLE emp_sal
(
EMPNO NUMBER 4,
SAL NUMBER (7.2));and a similar table in a SQL server:
SQL Server:CREATE TABLE emp_sal
(
EMPNO NUMERIC (4).
SAL NUMERIC (7.2));Then, you can create an insert trigger that replicates the data:
CREATE OR REPLACE TRIGGER dg4odbc_repl AFTER INSERT ON emp_sal
FOR EACH LINE
DECLARE
PRAGMA AUTONOMOUS_TRANSACTION;
BEGIN
INSERT INTO 'emp_sal"@MSODBCSQLSERVER_DG4ODBC_EMGTW_1123_DB '.
VALUES (: new.empno,: new.sal);
COMMIT;
END;
/-Note the validation, otherwise risk of ORA-6519
When you now insert a record into the Oracle database:
insert into emp_sal values (1234, '1200,89');
the trigger is activated and inserts the record in SQL Server:
Select * from 'emp_sal"@MSODBCSQLSERVER_DG4ODBC_EMGTW_1123_DB;
EMPNO, SAL
----- -------
1234 1200.89It works fine when you post data insert, but as soon as restore you the insert only data Oracle will be cancelled - data will remain as long as the independent transaction dedicated to its SQL Server insert:
insert into emp_sal values (1384, '1200,89');
Rollback;
Select * from emp_sal;
EMPNO, SAL
----- -------
1234 1200.89Select * from 'emp_sal"@MSODBCSQLSERVER_DG4ODBC_EMGTW_1123_DB;
EMPNO, SAL
----- -------
1234 1200.89
1384 1200.89So I strongly recommend to use the DG4MSQL gateway which is able to participate in distributed transactions and allows validation/restore transactions.
DG4ODBC lie on OTN (http://www.oracle.com/technetwork/database/enterprise-edition/downloads/index.html-online check out the "See all" link for your favorite platform), cloud of delivery of software Oracle (https://edelivery.oracle.com/) or "My Oracle Support".

Way EASIER to write this in a sql or plsql
I have a select as below where his output can be one line or several lines or lines nil. Select can bring nulls, R, C, O
(A) in the case of the lines suck, I want ln_status to be «#»
(B) in case if there is at least one row with O, ln_status should be O
(C) if the criteria A and B is not filled, in case if there is at least one firm, ln_status has to be C
(D) if only a single record with R, ln_Status must be 'o'
is it possible to write more simply without question several times or using plsql. Thank you
Select the status INTO ln_status
from TableA
where col1 = < col1 >
Frank addresses the point that you wrote that there could be no line and also status is null as a possible outcome.
Max (Status) has the null value distinguishes but count (*) = 0, because it returns a number greater than 0 in the case of rows returned with the State is set to null.

Published by: Bilal on December 27, 2012 10:07Bilal, thanks for the nice problem! Another possibility to double check is to write a small PL/SQL function that returns 1 if a duplicate id is found, then equate to 0: "NUMBER of RETURN of Duplicate_Token_Found (p_str_main in VARCHAR2, p_str_trial VARCHAR2). It should analyze the second string and could use p_str_main LIKE '%', | l_id | ', %' for each id. In any case, the query complete (without that) is given below:

Of course; This is in fact how CREATE TABLE always works. The CREATE TABLE statement will trigger an error and does not create anything, if a table with the same name already exists.
If you are looking for a way to avoid triggering an error, I don't think that there is nothing in SQL.
In SQL * Plus, you can place the CREATE TABLE statement in a script (let's call it create_table_2.sql) and write another script (create_table_0.sql) that does nothing, or maybe displays a message like "the Table already exists. In another script (create_table.sql), you can detect if the table exists and, depending on the results, call create_table_2 or create_table_0. I know, it's not pretty. See {message identifier: = 4367027} for a somewhat analogous situation. -
Hello
I need to write an efficient query because the query about 4 checks to be made on the lines before you return one row. Here's a sample script in query to create the table:
CREATE TABLE "myschema". "" Complaint. "

"Compalint_ID" NUMBER (20.0).
"ReplyTime' NUMBER,-it would be in a few minutes
"CREATION_TIME' TIMESTAMP (6).
NUMBER OF 'STATUS ',.
"TYPE" NUMBER
"CH_PKRTBL_Complaint_ID" ("Compalint_ID") PRIMARY KEY CONSTRAINT

I want to write an efficient pl/sql-sql query with the least time to return a row based on four following priorities/controls in the order specified below:
1 return any line that contains a TYPE = 11
2. If no line found for 1 check then
calculate a difference in time for all of the lines as: time_difference (CREATION_TIME - ReplyTime)
and back to the line that has more big differene in - ve (it is the line which expired first)
3. If now the found line to check then the 2
rank next where STATUS = 22
4. If no line found to check then the 3
calculate a difference in time for all of the lines as: time_difference (CREATION_TIME - ReplyTime)
and back to the line that has a smaller difference in + ve (it is the line that will expire then)
Kindly help me in this task.
Thank you.@1
I have the suggestion of Daniel while avoiding reserved words and now I see an error in copy/paste complaint_ casetypestatus when 22 then 22 end check3@2
Bilal already you made in the right direction, anyway: as many others pointed out that you can not combine functions of the group the way which you intend to so using functions analytical has been the only issue keeping all lines and the calculation of the required amounts and charges in the query internal to combine in the outer query.
complaint_type case when 11 11 then end keeps only the 11 complaint_type all other complaint_type null values
Max (case complaint_type when 11 11 then complete) on check1_max (order by NULL rows between unbounded preceding and following unbounded), calculates the global maximum of the expression (in all the rows of the table)@3
I used systimestamp - (creation_time + reply_time / 60/24) just to produce a positive or negative number as your time_difference (CREATION_TIME - ReplyTime) somehow confused me (timestamp less number gives timestamp if positive or negative is not an appropriate question) so the above expression as used so far is something you know how (re) set. Other required clarification/explanation at this stage.@4
If the fraction of the second precision is not necessary using the date data type should be sufficient (environmental CAR you cannot rule out dealing with the events with the same timestamp) and what is the thrown error using systimestampConcerning

Help for writing an extension for SQL Developer
Hi all
I want to write an extension for SQL using JDeveloper and Oracle Extension SDK developer and I have a few questions.
(1) is there some imports I need to sign up for the use of certain classes for SQL Developer?
(2) how can I do a new item from the context menu in the area of connections in the left?
(3) is there an example for this, because I have read a few posts of Sue and Kris Rice, but I figured out how to make the extensions only for JDeveloper.
Thanks in advance!SQL Developer Connection browser uses a different site from the JDeveloper Application browser id. The site id OK to use for a listener from context menu is "db_nav". If your listener statement would look like this:
My.listener.Class
Note that a listener can be registered on several sites (if, for example, you wanted as your listener to trigger for publishers, you can use "db_nav; Editor"for the site id.
You can post questions on the development of SQL Developer extensions on the developer forum SQL: SQL Developer this forum is monitored by the staff of SQL Developer.

Use the keyword sql 'in '. If you don't know how, I've heard good things about the book Teach Yourself SQL in 10 Minutes by Ben Forta.

Syntax of PL/SQL without papers. Keyword 'private '.
Hello
I'm a PL/SQL-programmer and programmer Ada too. PL/SQL is derived from Ada83. Now since I'm used to Ada sometimes I Ada syntax elements in the PL/SQL code. Normally, the PL/SQL-compiler complains and does not compile. But look at the following example:
create or replace package privatetest is
var varchar2 (100): = 'Test ';
operative;
private - Word - key undocumented
PrivateVar varchar2 (100): = 'Test ';
end privatetest;
/
create or replace package body is privatetest
test procedure
is
l_var varchar2 (100);
Start
l_var: = privatevar;
PrivateVar: = l_var;
end test;
end privatetest;
/
This can be compiled with PL/SQL release 10.2.0.4.0. Private package dry parts are normal in Ada Ada allows the children to packaging and then you need this mechanism of masking. In more complex situations, I met a strange behavior during execution so 'private' is used in PL/SQL.
Question: Is this a historical vestige that the compiler accepts the keyword or ist it plans to allow the private parts child packing in the future releases from PL/SQL?
Kind regards

How the sql query to sort the records by variable
Feel like using PHP to know how to write the query SQL ORDER BY
value time from list/menu form field ("sort_menu") and the values in the list are the columns of the database
SELECT *.
OF rentals_info
WHERE rentals_info.active = 'yes '.
Thanks for your help,

a column of the table as a variable. You need to adapt the code by hand, and
Once you do, the recordset can be is no longer recognized by
Dreamweaver. Thus, you must have first page in case the
Bindings panel shows more the fields in your recordset.Begin by creating the Recordset without the ORDER BY clause and have
your page as you want it. When everything is done, add the following
code at the top of the page:<>
create a table of column names that can be used for sorting
$permitted = array ("price", "space");
checks if the sort_menu variable contains a valid column name
If (isset($_GET['sort_menu']) & in_array ($_GET ['sort_menu'], $permitted)) {}
$sort = $_GET ['sort_menu'];
} else {}
the value of a default column for sorting
$sort = "price".
}
?>This assumes that the sort columns are called price and region.
Change these values according to your configuration.You can now add ORDER BY $sort to the SQL of the Recordset.

How to convert this SQL PL/SQL query
Basically, I need to create an anonymous block that will display the name of each student, family name and the number of students who scored less than test 1 that the student.
So basically you need to find the number of students scoring less than this particular student and we do it for all students of the table.
So, for this particular query, I designed my code in SQL
Select g1.gr_fname, g1.gr_lname, count (*)
grade g1, g2 grade
where g1.gr_t1 > g2.gr_t1 and
G1.std_code = g2.std_code
G1.gr_fname group, g1.gr_lname;
But I am unable to get the logic of how to run it in PL/SQL, something missing a minor detail to run the same in PL/SQL
could someone help me please with the logic.
Thank youYou can write it in pl/sql like this
begin for i in ( select g1.gr_fname, g1.gr_lname, count(*) cnt from grade g1, grade g2 where g1.gr_t1 > g2.gr_t1 and g1.std_code = g2.std_code group by g1.gr_fname, g1.gr_lname; ) loop -- I have just wirtern the output into the buffer. You can do what ever you want here. dbms_output.put_line(i.gr_fname||'/'||i.gr_lname||'/'||i.cnt); end loop; end;
