Parse SQL string using Zql or SQL4J
any used zql or sql4j.
if then plz give me some example
import org.apache.xerces.dom.DOMParser;
import org.w3c.dom.Document;
import org.w3c.dm.NodeList;
DOMParser parser new DOMParser();
parser.parse("xyz.xml"); // Instead of xml file it could be a InputStream.. not sure though
// You need to llok at documentation
Document doc = parser.getDocument()
// Once you have got the Document you can manipulate it using DOM api
// For example following code prepares a list of nodes having a tag = "product_id"
NodeList prodList = new NodeList();
prodList = doc.getNodeByTagName("product_id");
Hope this helps !!!

Parsing a string using StringTokenizer
Hi,
I want to parse a string such as
String input = ab{cd}:"abc""de"{
and the extracted tokens should be as follows
ab
cd
"abc""de"
As a result, I used the StringTokenizer class with deilmeter {,},:
StringTokenizer tokenizer = new StringTokenizer(input,"{}:", true);
In this was, I can separate the tokens and also can get the delimeters. The problem is I don't know how to parse the string that has double quote on it. If a single quote " is taken as a delimeter then
", abc, ",", de," all of them will be taken as a separate token. My intention is to get the whole string inside the double quote as a token including the quotes on it. Moreover, if there is any escape character "", it should be also included in the token. Help please.
ThanksA bit of a "sticky tape"-solution...
import java.util.StringTokenizer;
public class Test {
public static void main(String[] args) {
String input = "ab{cd}:\"abc\"\"de\"";
StringTokenizer st = new StringTokenizer(input, "{}:", true);
while(st.hasMoreTokens()) {
String token = st.nextToken();
if(token.startsWith("\"") && token.endsWith("\"")) {
token = token.substring(1,token.length()-1);
System.out.println(token);

Need Help Parsing JSON String using PLJSON
Hello,
I have JSON stored in a database field:
--Query
select data1 from table1 where id= 339207152427;
--Results:
[{"name":"Home"},{"code":"JPNWC74ZKW9"},{"start date":"01\/02\/2014"},{"person name":"hhh, RamS"}]
I need to parse the above results into 3 fields in a separate table. For now, i'm just trying to parse the results using PLJSON, but am getting the ORA-20101: JSON Parser exception - no { start found error when running the following pl/sql block:
declare
VIN_JSON varchar2(4000);
jsonObj json;
listOfValues json_list;
listElement json_value;
begin
select data1 into VIN_JSON from table1 where id= 339207152427;
jsonObj := new json(VIN_JSON);
listOfValues := jsonObj.get_values();
for i in 1..listOfValues.count loop
listElement := listOfValues.get(i);
end loop;
end;
I believe my syntax is close, but was hoping for some further instruction.
Thanks in advance!
JohnI have no idea what you are trying to do or in what version so help, at this point, is not possible.
Let's start with this:
I need to parse the above results into 3 fields in a separate tableAnd the parsing rules?
And what the result should be?
You apparently want us to guess. Which is something most of us do not like to do. (and don't forget your full version number if you want help).
PS: This forum has a FAQ: I recommend you read it as you didn't even put your listing into tags. -
How to parse xml string using JSTL
Suppose this is my string:-----
<books>
<book>
<title id=1>Book Title A</title>
<author>A. B. C.</author>
<price>17.95</price>
</book>
<book>
<title id=2>Book Title B</title>
<author>X. Y. Z.</author>
<price>24.99</price>
</book>
</books>
and I want to read title id = 1 then, how to parse it, I found tutorials regarding parsing simple xml document but how to parse attributes of a given XMLBut both of them either parse a file or data from an input source. I don't think they handle strings.An InputSource can be constructed with a Reader as input. One useful subclass of Reader is StringReader, so you'd use something likeDocument doc = documentBuilder.parse(new InputSource(new StringReader(myXMLString)));

Workspace to parse SQL statements from multiple database schema's
Hi ,
When go through the following link of workspace admin user :
Home>HTML DB Workspace Administration>Manage Services>Schema Reports>Workspace Schemas there I saw "Your workspace has the privilege to parse SQL statements using the following database schemas. Note that the terms database schema and database user can be used interchangeably.
" at the right pane.
So how can i make my workspace to parse SQL statements from multiple database schema's ?That must be listed there .But i have only one schema in view ? Can i make it multiple ?If then How ?
Anybody have an idea ?
ROSYAssign as many schemas to your workspace as you want using the administration app. Read about it in the doc.

SQL String is having like select col1, col2, col3 from table_name;Looks like you're tring to write a generic way of outputting the results of a query to a file.
You won't do it the way you're trying to, because your dynamic SQL means that you don't know the resultant columns of the query so that you can output them. To do that you need to use the DBMS_SQL package to describe the query and fetch the returned columns by position e.g.

Passing / parsing XML String IN / OUT from PL / SQL package
Hello, People !
I am wondering where can I find exact info (with code sample) about following :
We use Oracle 8.1.6 and 8.1.7. I need to pass an XML String (could be from VARCHAR2 to CLOB) from VB 6.0 to PL/SQL package. Then I need to use built in PL/SQL XML parser to parse given string (could be large hierarchy of nodes)
and the return some kind of cursor thru I can loop and insert data into
different db Tables. (The return value may have complex parent/child data relationship - so I am not sure If this should be a cursor)
I looked online many site for related info - can't find what I am looking
for - seems like should be a common question.

I am parsing a string in PL/SQL and at a certain point(Length 45) of the string I would like to add a carriage return (Chr(10)), then continue with the string at that point and then again if the string is greater than Length 45 add a carriage return.
I program in Powerbuilder and have figured it out, but I have a problem when trying to add a carriage return at a certain point in the string in PL/SQL. There is the REPLACE(), but that will replace everything, but I only want to add it at that certain point of the string. With the PB function I can add the carriage return at a certain point, see code:
Li_pos = PosA( Ps_data, '*')
DO WHILE Li_pos > 0
ll_length = Li_pos - ll_old_pos
IF ll_length > 45 THEN
ll_old_pos = Li_pos
Ps_data = ReplaceA( Ps_data, Li_Pos, 1, ls_carriage_rtn) **This function gives me the ability to add a carriage return at a certain point in the string. **
Li_pos = PosA( Ps_data, '*', Li_pos + 1 + ls_carriage_rtn)
ELSE
Li_pos = PosA( Ps_data, '*', Li_pos + 1)
END IF
LOOP
I have incorporated the same logic in PL/SQL but I am looking for something similar to the ReplaceA function in PB, that will replace at a certain point in a string. I use an '*' as a placeholder and measure the length. Below is the PL/SQL code:
t_pos NUMBER;
t_old_pos NUMBER;
t_length NUMBER;
BEGIN
t_old_pos := 0;
t_pos := INSTR(in_model_list, '*');
WHILE t_pos > 0 LOOP
t_length := t_pos - t_old_pos; -- This looks at current position minus the old position, measures the length
IF t_length > 45 THEN
t_old_pos := t_pos;
*** add that carriage return
t_pos := INSTR(in_model_list, '*', t_pos + 1 + Chr(10)); -- get the new position
NULL;
ELSE
t_pos := INSTR(in_model_list, '*', t_pos + 1);
END IF;
NULL;
END LOOP;
Here is the data, what it looks like: William 112,* 500-A,* 500-U,* 520,* 560-A,* 560-E,* 680-E,* 680-F,* 680-V*
Any help would be much appreciated.
Thank you,

To generate sql string of desired row using function.
Hi l,
I return the below query to get sum of vehicles which falls between the specific weight ranges.
It returns 20 rows( As I selected 4 classification vehicles).I was expect only 4 rows .One row for each classification of vehicles.
Is there a way if do some loop or decode in my function logic?
will tht work?
"(This is only smple. In my real appilication, if I use 15 classification vehicles it returns 320 rows. But i expect only 16 rows - 0 to 15 one row for each classification .Duirng runtime I'm getting an error as buffer string too small)"

Edited by: user10641405 on Jun 19, 2009 4:15 PMSay you have a 3 tables
Table name Description rowcount()
============================================================================
weight_report_data report table having weights and counts 4
repo_param having id column gives different classes 4
repo_range_param is detail table of repo_param with id 4
as foreign key and defines weight
min max ranges.
Now you need to report
per class how many weights weights are there ?
--not understood report id clearly in relation to weight_report_data
step1:
need to map each row of weight_report_data againist its class.
select wrd.weight,wrd.weight_count,(select rp.class||rp.value
from repo_range_param rrp,
repo_param rp
where rrp.id= rp.id
and rp.id=1 -- add your other join condition
and wrd.weight between rrp.min and rrp.max ) class_nm
from weight_report_data wrd ;
This will give 4 rows , i.e for each row in wrd it tells which class it falls.
now you want to group by class_nm to get sum or count of weights.
step2:
select class_nm,sum(weight), count(weight), sum(weight_count)
from (
select wrd.weight,wrd.weight_count,(select rp.class||rp.value
from repo_range_param rrp,
repo_param rp
where rrp.id= rp.id
and rp.id=1 -- add your other join condition
and wrd.weight between rrp.min and rrp.max ) class_nm
from weight_report_data wrd ) wrd_classnm
group by class_nm;
I hope this helps .

Problem in parsing a xml string using dom parser
i want to parse a Xml String using a Dom parser......the parse function in dom parser takes only input stream as argument.......so i made the code as
InputStream inputstream = new StringBufferInputStream(XmlData) ;
InputSource inputSource = new InputSource(inputstream );
but saxexception is coming and also warning called
"java.io.StringBufferInputStream in java.io has been deprecated"
please help me.........i want to parse a Xml String using a Dom
parser......the parse function in dom parser takes
only input stream as argument.......This is not true of the DOM parser in Java 1.4. So you might want to get rid of your old parser and replace it by something more current. Or perhaps you are using 1.4 and you just didn't read all of the API docs. -
Hi all,
How do i use Native SQL String in the Reciver JDBC Adapter.
Do i need to change the message format could u suggest me some blogs on the same.
Also please can anyone let me knw if i can use this for stored procedure.hi aditya,
there shud be no format as such. for sql xml format there are specific structure. but for native sql there shudnt be any specific structure.
as pointed in sap documentaion:
Instead of an XML document format, a text is expected that represents any valid SQL statement.
When inserting a line into a table the corresponding document looks as follows:
INSERT INTO tableName (column-name1, column-name2, column-name3) VALUES(column-value1, column-value2, column-value3)
so jus make sure that u give a valid sql statement becoz if will be passed as it is to the database and try ur scenario.
regards,
latika. -
Parse a string that uses nested string delimiters
I’m looking for a way to parse a string that uses double quotes as the delimiter that contains a nested string with double quotes. I want to keep the double quotes in the nested string. Is there a function in Labview that I can use to easily do this? Does Labview have a command line parser / interpreter?
The string example is: While match "Send Test "Sleep 5" ">""
The result string would be: Send Test "Sleep 5" ">"Here is another solution which is slightly faster. Speed won't be
an issue unless you are running millions at a time, as in my test the
difference was only 1-2 ms in 10000 iterations. In this image the
Match Pattern function retrieves the desired string, including the
outside quotes, so the String Length and String Subset functions are
used to remove the first and last characters of the result.

New C20's Are super loud! Over 65db! Is this normal?
We just recieved two new C20's. However, they are super loud. I've measured the sound at around 65db. I've set the fan mode to "quiet" in the bios, but that made no difference. Is this normal? Thanks! Solved! Go to Solution.
