Well, you can start off by reviewing the SYSDATE command and the TO_DATE and TO_CHAR functions. Also, review addmonths etc.

dont use NE in the select statements, it may effect performance also. Instead use if statements inside
loops.
loop at t_caufv.
read table it_chrd............
if t_caufv-objnr ne it_chrd-objnr.
read table it_jest..........
   if   if t_caufv-objnr ne it_jest-objnr.

How can get a database like ****.SQL file for test in sqlplus in oracle8i

How can get a database like ****.SQL file for test in sqlplus in oracle8i,I am a beginner,thanks

I'll give it a guess as to what it is you want but I'm afraid you'll have to give some more information to go on. I appreciate it's difficult for people who are beginners or who don't have English as their first language.
Are you trying to run a SQL file? From SQL*plus you can do either of these:
SQL> start my_file
or
SQL> @my_file
N.B.: if th efile has a .sql extension you don't need to include it, but you do for any other file extension e.g.
SQL> @myfile.run

How can i make a pl/sql function for BLOB datatype

hi..anyone here who is very familiar about BLOB datatype. i have a COLUMN_ID, COLUMN_A in a certain TABLE_1. COLUMN_A is blob datatype that contains almost 250,000rows
SQL>select column_A from table_1 where column_id=1234567
column_A
00000001000000010000000606D4E833074B69EC06D4E91F074CO18406D50C58074C031E
how can i make a user-defined function to compute and convert this blob datatype into decimal length value. this hex value are points in the map.. the function must contain
1.get the length of a blob then
2.convert blob to variable hexadecimal characters by parsing it into 8
3.to_number function or other function used to convert haxadecimal characters to decimal numbers
4.phythagorean formula to compute length between two points. this is the formula i think LENGTH =
SQRT(power((coordinate_x-prev_coordinate_x),2)+power((coordinate_y-prev_y),2));
after this when i type this
SQL>select user_function(column_A) from table_1 where column_id=1234567
user_functions(column_A)
--output length will be in decimal value already
the function will goes like this
step1 is to get the blob length
00000001000000010000000606D4E833074B69EC06D4E91F074CO18406D50C58074C031E
step2 is parsing of data by eights
00000001 =>1
00000001 =>1
00000006 =>6 (number of coordinates)
06D4E833 => X1
074B69EC => Y1
06D4E91F => X2
074CO184 => Y2
06D50C58 => X3
074C031E => Y3
step3 to_number function used to convert hex char to decimal
step4 compute by phytagorean (NOTE ! when computing length the third parsed eight will tell how many coordinates are there..the number of coordinates is ranging from 2 up to E..above example shows 6 coordinates so it means
LENGTH1 =
SQRT(power((X2-X1),2)+power((Y2-Y1),2));
LENGTH2=
SQRT(power((X3-X2),2)+power((Y3-Y2),2));
TOTAL LENGTH=LENGTH1 + LENGTH2
thanks

its my first time to use that.There's got to be a first tiem for anything. Be brave.
btw if theres more easy suggestion pls feel free..Well of course the easiest solution would be if the calling program passed in the parameters as separate arguments instead of glomming them together in a string that has to be parsed. This sort of kluj really ought not to have survived into C21.

How can I write a SQL statement which checks if a table exists?

How can I write a SQL statement which tells me whether a table exists?

execute an sql query: select * from <tablename>
catch the exception n check whether the erroe code
matches the one that occurs for table doesn't exist
that's itHow is your answer any different from the one given in the first reply?
It isn't.
As WorkForFood says DatabaseMetaData has a bunch of methods for getting information about tables but this is more useful when you don't know the names of any of the tables.. it sounds like you do so I would concur SELECT from table is probably the quickest way to go. If it helps the Xopen error should be either S1000 or 42S01 (I think) but I would try and see if there is a specific vendor code for table not found/not exists error and check for that.

How can I Write a sine wave in an Access-file?

I measure a sine wave in LabView 6i. How can I write the datas automatically to an Acces-file, at the same time?
In my program, I managed it with Execute SQL.vi, I change a number in a SQL statement(String) -> after this I push start and then it writes the statement in the Access-file.
The problem is, it writes only one data per measurement in the file. How can I write all datas in the Access-file and measure the wave at the same time?
Thanks for help!
Attachments:
getwave.vi ‏49 KB

On the waveform palette, you will find a "to components" vi that you can break out the array of the waveform. You can then, using a for loop write all of the values from the waveform.
Better yet, there are examples in the database toolkit manual on pages 3-13 to 3-15 that deal with reading arrays (and even has a waveform example).
Good luck!

How can I write into a table cell (row, column are given) in a databae?

How can I write into a table cell (row, column are given) in a database using LabVIEW Database Toolkit? I am using Ms Access. Suppose I have three columns in a table, I write 1st row of 1st column, then 1st row of 3rd column. The problem I am having is after writing the 1st row 1st column, the reference goes to second row and if I write into 3rd column, it goes to 2nd row 3rd column. Any suggestion?
Solved!
Go to Solution.

When you do a SQL INSERT command, you create a new row. If you want to change an existing row, you have to use the UPDATE command (i.e. UPDATE tablename SET column = value WHERE some_column=some_value). The some_column could be the unique ID of each row, a date/time, etc.
I have no idea what function to use in the toolkit to execute a SQL command since I don't use the toolkit. I also don't understand why you just don't do a single INSERT. It would be much faster.

How can I write cursor which tell me no record exists

Hi Experts,
I want to know how can I write a cursor which told me no record exists before opening and running the loop.
So I want that if no record exist then I dont want to run loop and open the cursor.
Example: cursor c1 is select empno from scott.emp where empno=10
In procedure body, I want to check if there is no record against my cusor then I don't like to open it.
Thanks

SQL> All SQLs are cursors. Every single SQL passed to Oracle for parsing and execution is a cursor. So it does not make sense to use one SQL cursor for testing the existence of a specific row, and then another to return the row.
That kind of logic is PL/SQL logic and a single SQL cursor need to be used.
PS. Make sure that the SQL projection only includes the columns needed in PL/SQL. If the SQL is a pure exist row? check, then do not return any column and use a literal value as the projected column.

How can I enable embedded pl/sql gateway to run on port 80

I have a new 11G install on OEL 4.0, database created. I would like to be
able to access the instance using the pl/sql gateway. Works fine with
port 8080, the default. How to I enable it to run on port 80?
I found this statement in the following docuementation:
http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14259/xdb22pro.htm#ADXDB2500
Using HTTP(S) on Nonstandard Ports
By default, HTTP listens on a nonstandard, unprotected port: 8080. To use HTTP(S) on
the standard port, such as 80, your DBA must chown the TNS listener to setuid ROOT
rather than setuid ORACLE, and configure the port number in the Oracle XML DB
configuration file /xdbconfig.xml.I have root priviledges on the box.
I've tried setting the listener file permissions:
chown root:dba /u01/app/oracle/product/11.1.0/db_1/bin/tnslsnr
chmod 6775 /u01/app/oracle/product/11.1.0/db_1/bin/tnslsnr
Also put root in the dba group.
The permissions turn out like this:
-rwsr-sr-x 1 root dba 830854 Jun 17 21:04 /u01/app/oracle/product/11.1.0/db_1/bin/tnslsnr
I stopped the listener, bounced the database, and started the listener again.
But it still shows the process being owned by oracle:
oracle 29682 1 0 21:08 ? 00:00:00 /u01/app/oracle/product/11.1.0/db_1/bin/tnslsnr LISTENER -inherit
Changing the port is easy:

* Is your computer or network protected by a firewall or proxy? Incorrect settings

This is the entry from the listener log:

How can I write a program that compiles without warnings?

I tried the following with the 1.5 beta-compiler (build 28; I think):
class Y {
     public static final class Pair<X,Y> {
       private X fst;
       private Y snd;
       public Pair(X fst, Y snd) {this.fst=fst; this.snd=snd;}
       public X getFirst() { return fst; }
       public Y getSecond() { return snd; }
       public String toString() { return "("+fst+","+snd+")"; }
public static void main(String... args) {
     Pair[] pairArr = new Pair[10];              // supposed to be an array of Pair<Integer,Integer>
     for (int i=0; i<pairArr.length; i++)
         pairArr[i] = new Pair<Integer,Integer>(i,i);
     for (int i=0; i<pairArr.length; i++) {
         Pair<Integer,Integer> p = pairArr; // unchecked warning
     System.out.println(p);
     Integer first = p.getFirst();
     Integer second = p.getSecond();
// ... more stuff ...
It turns out that I get an unchecked warning when I extract an element from the array of pairs. Okay, that's fine. How can I avoid the warning? I had expected that an explicit cast would help.
Pair<Integer,Integer> p = (Pair<Integer,Integer> )pairArr;
With a cast I'm telling the compiler: "I _know_ what I'm doing; please trust me." But the compiler still issues a warning.
How can I write a warning-free program in this case? The only thing I can think of, is not using the parameterized type Pair in its parameterized form. But it's not the idea of Java Generics that I refrain from using parameterized types. What am I missing?

It turns out that I get an unchecked warning when I
extract an element from the array of pairs. Okay,
that's fine. How can I avoid the warning? I had
expected that an explicit cast would help.
Pair<Integer,Integer> p = (Pair<Integer,Integer>
)pairArr;
With a cast I'm telling the compiler: "I _know_ what
I'm doing; please trust me." But the compiler still
issues a warning. Yes, but at least you were able to change the warning from "unchecked assignment" to "unchecked cast" which is a little shorter ;-)
Seriously , since arrays of generic types are disallowed, there is probably no way to get rid of these warnings - which makes a strong point for eliminating "unchecked" warnings altogether (see the other thread "selectively suppressing compiler warnings")
Cheerio,
