If you want to read user input from the keyboard look at System.in (http://java.sun.com/j2se/1.4/docs/api/java/lang/System.html#in)
and also will u tell me how to clear the screen(just

How to compare char and numc in select query
Hi Experts,
I am using For all entries to combine two tables.
I want to fetch the data from these tables.
The field in one table char, and in another the field is numc.
1st Query from table BDCP2 and get the tabkey value is like (2000000000000000000086200000000000000000000)
2nd query For all entries found,
query table ESTMJ with the following parameter.
ESTMJ-RECN = BDCP2-TABKEY+3(20)
1.TABKEY CHAR 254
2.RECN NUMC 20
How to compare these two ?
Regards,
Bindhu Priya.for two fields numc & char , please check out their Conversion routine in their respective Database table.
1st in SE11-> enter table names in different sessions. and check out the data domain used by this fields
In their respective domains of fields, click on tab 'DEFINITIONS', then check out the conversion routines in Output Characteristics of the Data Domain of field
From my point of view, both the Conversion routines should be the same.
If Conversion Routines are not there, then insert suitable Conversion routine for both the fields domain
For help for for conversion routines:

How to determine INT and FLOAT in a DECODE statement
Can anyone help me with the following problem:
I have a column defined as a NUMBER(15,4). I am trying to determine the java type using the getScale() method in ResultSetMetaData. When the scale is greater than 0, then it is an float, else it is an int. In this case, the getScale() method should return 4. However, when querying with a DECODE statement on the NUMBER(15,4) field, the getScale() method always returns 0 and the value is therefore converted to an int. Anyone knows how to solve this problem?
ThanksAlcides,
Oracle NUMBER data type is mapped to "java.math.BigDecimal" class.
You will find more information in the JDBC Developer's Guide and Reference which is part of the Oracle documentation and available from:
http://www.oracle.com/technology/documentation/index.html

But okay, let's say I know that. Let's say you bothered to point out that you've already done that. Further, let's say I do have knowledge of the subject at hand. Maybe I'm an expert.

How to show kf and char in the adjecent column
hi to all
I am a newbie in the BI..and i have some problem.
i have 52 weeks in the column and along with that i need to show amount column also.how can it possible.i dont want to see weeks under amount.
employee |amount||week 1| week 2|...(like this up to 52 weeks) |total days|
i took employee as the char and amountas kf.for weeks i used 0CALWEEK.
but the problem is when i am executing the Query,weeks are comeing along with amount also.i need separate amount and weeks .
could you people please give some clues?
thanks alotHi gaurav,
its not the Cumilative amount.
for exp....
i have year/weeks and amount along with Employee details
i need to planify that data.some data will be with input ready cells in planification.
i need the result like this..
employee | empname | empoffice | tarif(amount) | week1| week2 | week3 |....week52| total days|
how can ido this...i got some result with variable..but its a bit lenghty to creat 52 variables like weeks na.
so i am looking for a some what good idea.
i put employee details in Row and tarif and 0calweek in columns.i create filter for version.
the problem i am facing is when i keep TARIF in column along with 0calweek...the feild is not ready for input. -
How to display properties of dimension on the input form and report in bpc
Dear Expert,
Please tell me how to display properties of dimension on the input form and report in bpc. I can only display dimension number.
thanks so much
hungthHi Hungh,
If your are using BPC 10 with EPM add in client, you can use the function:
EPMDimensionProperty ()
This function retrieves the properties of a specified dimension in a specified cell range.
Thanks, Safa -
How can i use in the same time input line and mic to recorder in several track whit SONAR

Thank you. Sorry for my english
Depending on which soundcard you have there, but if your card is capable for
ASIO -> activate I/O drivers on Sonar/Options/Audio/Drivers -tab (mic/line sources should be listed there --> activate) and select the mic or/and Line sources on tracks "I" - dialog
WDM/KS -> use the Surround Mixer or windows recording controls for recording source selection (mic should be listed there)
MME32 - > same w/ WDM/KS
If you use Asio4All --> same w/ WDM/KS & MME32
No mic and line source simultaenously w/ WDM/KS and MME32.
You perhaps be able to do this w/ kX drivers.
jutapa
ADDED:
You can also install modded version of Audigy 2 drivers/software but I have never done this w/ Li've! 5. so I can't be sure if you get ASIO support for your card.
Here are the instruction --> http://www.tech-pc.co.uk/audigy-2.php

How to get the fixed result in a DES/CBC mode with fixed input data and fix
How to get the fixed result in a DES/CBC mode with fixed input data and fixed key. Below is my program , I tried to get the checksum of the DESInputData with the DESKeyData, but each time the result is different.
below is my code:
byte[] DESKeyData = {(byte)0x01 ,(byte)0x01 ,(byte)0x01 ,(byte)0x01, (byte)0x01 ,(byte)0x01 ,(byte)0x01 ,(byte)0x01 };

SecretKeySpec skey = new SecretKeySpec( DESKeyData, "DES" );
Cipher cipher = Cipher.getInstance("DES/CBC/NoPadding");
cipher.init( Cipher.ENCRYPT_MODE, skey );
byte[] result = cipher.doFinal( DESInputData );Use class javax.crypto.spec.IvParameterSpec to specify IV for CBC mode cipher:

How to define Length of char. and KF
During infoobject creation, how to define the length of char. and KF, is it related to master data text length ? Should we take other things into account? When we see one field in table, the length of the field was defined with 2, but its master data text length was more than 2, what's the reason for this things?
Edited by: hi ni on Apr 18, 2008 12:12 PMhi,
how to define the length of char. and KF, is it related to master data text length ?
ther business will have defined length and type for any characteristics. ex - Materail number may have lenth of max 15 and is Char type.
but for text max size is by default 40 chars.
Should we take other things into account?
get spec from client, that could be better and also consider the field used to map ur char/KF from source system.

How to set input delay and output delay when source Synchronous
ClkIN is the board clock which is connected to the FPGA. Clkif is the generated clock from ClkIN. The Device's clk come from Clkif. So, how to set input delay and output delay in this scene(within my understand, this is Source Synchronous)?
The example in many document, the input delay and output delay setting all refer to board clock(within my understand, this is System Synchronous). In that scene, the input delay max = TDelay_max + Tco_max; input delay min = Tdelay_min + Tco_min; the output delay max = Tdelay_max + Tsu; output delay min = Tdelay_min - Th.
So, I want to know how to set input/output delay in the Source Synchronous.
In system synchronous, I set input/output delay such as:
create_clock -period 20.000 -name ClkIN -waveform {0.000 10.000} [get_ports ClkIN]
create_generated_clock -name Clkif -source [get_pins cfg_if/clk_tmp_reg/C] -divide_by 2 [get_pins cfg_if/clk_tmp_reg/Q]
create_clock -period 40.000 -name VIRTUAL_clkif //make virtual clock
set_input_delay -clock [get_clocks VIRTUAL_clkif] -min 0.530 [get_ports DIN]
set_input_delay -clock [get_clocks VIRTUAL_clkif] -max 7.700 [get_ports DIN]
set_output_delay -clock [get_clocks VIRTUAL_clkif] -min -0.030 [get_ports DOUT]
set_output_delay -clock [get_clocks VIRTUAL_clkif] -max 1.800 [get_ports DOUT]
*******************************************************************************************So, first. Architecturally, the clock that you forward to your external device should not come directly from the clock tree, but should be output via an ODDR with its D1 input tied to logic 1 and the D2 tied to logic 0. This guarantees minimal skew between the output data and the forwarded clock.
ODDR #(
.DDR_CLK_EDGE("OPPOSITE_EDGE"), // "OPPOSITE_EDGE" or "SAME_EDGE"
.INIT(1'b0), // Initial value of Q: 1'b0 or 1'b1
.SRTYPE("SYNC") // Set/Reset type: "SYNC" or "ASYNC"
) ODDR_inst (
.Q (Clkif_ff), // 1-bit DDR output
.C (ClkIN_BUFG), // 1-bit clock input
.CE (1'b1), // 1-bit clock enable input
.D1 (1'b1), // 1-bit data input (positive edge)
.D2 (1'b0), // 1-bit data input (negative edge)
.R (rst), // 1-bit reset
.S (1'b0) // 1-bit set
OBUF OBUF_inst (.I (Clkif_ff), .O (Clkif_out));
This generates an output clock that is the same frequency as your input clock. This is consistent with your drawing, but inconsistent with your constraints - is the forwarded clock a 50MHz clock or a 25MHz clock?
I will assume your ClkIN goes to a BUFG and generates ClkIN_BUFG. Your first constraint generates a 50MHz clock on the ClkIN port which will propagate through the BUFG to (among other places) this ODDR.
create_clock -period 20.000 -name ClkIN -waveform {0.000 10.000} [get_ports ClkIN]
Assuming your forwarded clock is supposed to be 50MHz, then your 2nd command is close to correct
create_generated_clock -name Clkif -source [get_pins cfg_if/ODDR_inst/C] -combinational [get_pins cfg_if/ODDR_inst/Q]
With this done, you have successfully described the forwarded clock from your design. This is the clock that goes to your device, and hence should be the clock which is used to specify your input and output constraints.
set_input_delay -clock [get_clocks Clkif] -min 0.530 [get_ports DIN]
set_input_delay -clock [get_clocks Clkif] -max 7.700 [get_ports DIN]
set_output_delay -clock [get_clocks Clkif] -min -0.030 [get_ports DOUT]
set_output_delay -clock [get_clocks Clkif] -max 1.800 [get_ports DOUT]
If you want to get fancier, you could try adding a set_clock_latency to the forwarded clock to account for the board propagation of the clock
set_clock_latency -source TDtrace2 [get_clocks Clkif]
(But I haven't experimented with clock latency on a generated clock and I don't know for a fact that it works).

How to change the layout of an input file and write to an output file
Hi
I have a .csv file which has a layout as schoolNo. , county1,county2,county3,county4,county5
It will need to go into an output file as schoolNo. repeated and a county on each record .
ie., schoolNo.,county1
schoolNo.,county2
schoolNo.,county3
schoolNo.,county4
schoolNo.,county5
I wrote the java program as follows ..which results in this error
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException
BECAUSE :--
i know bec., the first record doesnot have county3,county4,county5 . So when the if loop for county3 lenght is checked it gives this exception .
Pls help me write this program ..thanks in advance .
/Here I open the input file and read in record by record
BufferedReader readin;
try {
readin = new BufferedReader(new FileReader(InFile));
String firstLine = readin.readLine();
String[] headers = firstLine.split(",");
columnCount = headers.length;
System.out.println("Columns in ZIP Master File: "+columnCount);
for(String input ;(input = readin.readLine()) != null; ){
recCount++;
input = input.substring(1);
String[] column = input.split(",");
if(columnCount == 10){
eachIP++;
// OUTPUT FILE
if(column[1].length()> 0) {
String mainStr = column[0] + "," + column[1] ;
Count++;
totalcolumns++;
writeOutFile.write(mainStr);
writeOutFile.newLine();
else{
bypassedCount++;
if(column[2].length()>0){
String mainStr = column[0]+ "," + column[2];
Count++;
totalcolumns++;
writeOutFile.write(mainStr);
writeOutFile.newLine();
else{
bypassedCount++;
if(column[3]..length()>0){
String mainStr = column[0]+ "," + column[3];
Count++;
totalcolumns++;
writeOutFile.write(mainStr);
writeOutFile.newLine();
else{
bypassedCount++;
}There are two split( ... ) methods; check the other one (the one with two arguments), it allows for empty entries to be counted, i.e. split(inputString, -1) gives you the wanted results.

How to input id data in jtable column 1 and load the detail in other column
Dear all,
I am new to java, I am writing a POS using Java. I want to scan goods barcode into column 1 of a jtable, then the program will load the product's name and price in
column 2 and column 3 from database. And also I want to have another row available where the barcode is scanned in previous row, i.e. I can add multiple products. And then I need to write the good's barcode to database. Please suggest any related article or code example. Thanks.Peter-Hon wrote:

Thanks.Your scanner will probably be a keyboard wedge, so any input from it will be equivalent to typing on the keyboard. You may be able to set it up to send a character, or sequence of characters that you can interpret as "move focus to the input cell, and input the remainder of the input there", if you can't do that, then you will have to just deal with the fact that people will end up scanning the bar codes into the quantity field. -
How to input data into an arraylist from a text file?
I am trying to take data from a text file and put that data into an arraylist. First here is the text file:
[item1, 10, 125.0, item2, 10, 12.0, item3, 20, 158.0]
3
4530.0
[item5, 65, 555.5, item4, 29, 689.0]
2
56088.5
[item7, 84, 34.5, item6, 103, 0.5, item8, 85, 1.36]
3
3065.1The text between the [ ] is the output from my arraylists. I have three arraylists. The first [ ] belongs to arraylist A, the second to arraylist B, and the third to arraylist C. The format of the arraylists is this:
<item name>,<# in stock>,<value of one item>
The first number below the arraylists in the text file represents the number of items in the list. The second number below the arraylists represents the total value of the items in the arraylists.

}Right now I am stuck on this and I cannot progress any further until I figure out how to input the data in the text file back into a arraylist.
Thanks in advance.Thanks but I figured it out. Heres a sample of the code i used to solve my problem:
try
//Warehouse A BufferedReader.
BufferedReader inA = new BufferedReader(new FileReader(inputFileWarehouseA));
//Warehouse B BufferedReader.
BufferedReader inB = new BufferedReader(new FileReader(inputFileWarehouseB));
//Warehouse C BufferedReader.
BufferedReader inC = new BufferedReader(new FileReader(inputFileWarehouseC));
//Warehouse details BufferedReader.
BufferedReader inDetails = new BufferedReader(new FileReader(inputFileDetails));
//Will hold values in warehouse arraylists.
String lineA = null;
String lineB = null;
String lineC = null;
//Will hold the details of each warehouse.
String line1 = null;
String line2 = null;
String line3 = null;
String line4 = null;
String line5 = null;
String line6 = null;
//Get the item count and total value for each warehouse.
while(inDetails.readLine() != null)
line1 = inDetails.readLine();
line2 = inDetails.readLine();
line3 = inDetails.readLine();
line4 = inDetails.readLine();
line5 = inDetails.readLine();
line6 = inDetails.readLine();
/**Assign the item count and total value to warehouse A.*/
//Cast.
int intLine1 = Integer.valueOf(line1).intValue();
double dblLine2 = Double.valueOf(line2).doubleValue();
//Assign the values.
this.intWarehouseAItemCount = intLine1;
this.dblTotalValueA = dblLine2;
/**Assign the item count and total value to warehouse B.*/
//Cast.
int intLine3 = Integer.valueOf(line3).intValue();
double dblLine4 = Double.valueOf(line4).doubleValue();
//Assign the values.
this.intWarehouseBItemCount = intLine3;
this.dblTotalValueB = dblLine4;
/**Assign the item count and total value to warehouse C.*/
//Cast.
int intLine5 = Integer.valueOf(line5).intValue();
double dblLine6 = Double.valueOf(line6).doubleValue();
//Assign the values.
this.intWarehouseCItemCount = intLine5;
this.dblTotalValueC = dblLine6;
/**Put the items back into the warehouses arraylists. */
//Add items to warehouse A.
while((lineA = inA.readLine()) != null)
warehouseAList.add(lineA);
//Add items to warehouse B.
while((lineB = inB.readLine()) != null)
warehouseBList.add(lineB);
//Add items to warehouse C.
while((lineC = inC.readLine()) != null)
warehouseCList.add(lineC);
}(this isn't the whole try statement its pretty long)
