JDeveloper, Java & XML :: Regular Expression For Exact Word And Occurrence
Mar 15, 2012
I need to search a specific pattern from a source code. In word, I need to check whether "getCode" has been called or not, for all the string inside double-quote("). Following are sample code lines -
Now, expression should be such that it will return true during check for 1, 3 and 4, although, for 3 & 4 getCode has been called for part of the String.
I'm trying to match all sentences that contain words starting with given search tokens at least once. For example: if the given search token words are one and two then only sentences like "one plus one is two" should match. And should not match sentences like "one plus three is four". I was able to come up with this but I need a AND condition which I'm unable to get it right.
select count(*) from dual where regexp_like('one plus one is two', '(^|s)one|three', 'i');
Currently this gives a count of 1. But needs to give a count of 0 when the regexp is fixed.
search words : one two
one is less than two -> match two is greater than one -> match onetwo is union of two numbers -> match onetwo is union of 2 numbers -> not a match as 'two' is not at the beginning of a word one is less than three -> not a match as two is not present.
I have a Identifier column with start and stop dates along with description .
Two dates are separated by '-'. But the position of that character(-) is not constant always. Depending on the instr function I am able to divide the start and stop dates. But I am getting the performance problem because of huge data
I think the same logic will be implemented by regular expression also . How to write the equivalent logic by using regular expressions
, My HTML string is like below. select '<CityName>RICHMOND</CityName> <StateCd>ABCD CDE <StateCd/><CtryCd>CAN</CtryCd><CtrySubDivCd>BC</CtrySubDivCd>' Str from dual Desired Output is<CityName>RICHMOND</CityName><StateCd>ABCD CDE <StateCd/><CtryCd>CAN</CtryCd><CtrySubDivCd>BC</CtrySubDivCd> i.e.
want to remove those spaces from tag value area having only spaces otherwise leave as it is.implement the same using Regular expression.
I would like to write a select that would return all places in DB that are commiting transaction.
E.g. package for testing:
CREATE OR REPLACE PACKAGE test.TEST_COMMIT AS PROCEDURE THE_ONLY_COMMIT_IN_DB ; END TEST_COMMIT;--not a match CREATE OR REPLACE PACKAGE BODY test.TEST_COMMIT AS
[code]....
The select should return 4 rows with --ok.
SELECT * FROM ALL_SOURCE ASO WHERE REGEXP_LIKE(ASO.TEXT,'commit(s*);','i' ) AND name = 'TEST_COMMIT'
I am trying to invoke program from my local Windows machine (exactly java executor, which is in my environment on c:javajdkinjava) using database package with Java stored procedure.
Everything is fired by SQLPLUS script, this script invokes package with Java stored procedure (jar loaded into Oracle) and that procedure is trying to invoke runtime process (syntax:
c:javajdkinjava -cp
and here ara my classes and main jar) using my local java executor. I added all permissions using dbms_java.grant_permisions (execution forced me to give permissions java.io.FilePermission to <<ALL_FILES>> for execute), moreover I added to my database user JAVASYSPRIV and JAVAUSERPRIV role. Unfortunately, beside this I am still getting error:
C:javajdkinjava not found (Note that lookup with PATH isn't done due to the oracle executable being setuid.)
I am writing a java stored procedure in my package. In the java procedure I want to issue a query to be fired on the user table from which I am calling the java procedure.
Some thing like following:
I am logged in to USER1 and my package is inside USER1. From this package I am calling the Java Stored Procedure. In java procedure I want to make a jdbc connection to USER2. The details of USER2(password, hostname,portno) are stored in a table called 'connection_details' and this table is in the USER1.
My problem is how can I issue the
SELECT details FROM CONNECTION_DETAILS for USER2
so that i can get the details..?
Do i need to first make jdbc connection to USER1 and then execute the above query for which i need similar details of USER1. How can i obtain the details of USER1 here.
I am thinking if I am already in USER1 then do I need to make the jdbc connection to USER1 and then execute the query?
I've this java source create or replace and compile java source named "Decodificador" as public class Decodificador { public static String decodifica(String codigo) return codigo;
and this function
create or replace function F_Decodificador(codigo varchar2) RETURN VARCHAR2 IS LANGUAGE java NAME 'Decodificador.decodifica(String) return String';
when I execute the function the result is:
ORA-29531: no method decodifica in class Decodificador
I need to call DB function through Java Hibernate.
My Sample XML File looks like. --------------------------------------------------------------- <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <hibernate-mapping> <sql-query name="getchequeno" callable="true"> ?:=call cz_nab_mw_fn_gen_ol_chq_no() </sql-query> </hibernate-mapping> --------------------------------------------------------------- I am getting below error while reading the file
"java.lang.RuntimeException: org.hibernate.HibernateException: Errors in named queries: getchequeno"
i`m trying to use pl/sql function to execute java class. I created 2 tables with around 100 values and java class with simple functionality. I need to create function to loop through my table1 and get with each iteration one value from table and pass that value as parameter to java class.
table1 is something like this:
ID NAME 1 name1 2 name2 3 name3 . . . . 100 name100
table2 is empty with same columns as table1 ( table2 is for data obtained from java returns ) I created in sql+ java class.
CREATE OR REPLACE AND RESOLVE JAVA SOURCE NAMED "myClass" AS import java.io.*; import java.util.* public class myClass { public static String fun(String strName)
[code]....
Then i wanna make a pl/sql function for:
1)For i = 1 Obtain first value from table1 (column name) and pass it throught java class then return value and save it in table2 with the same id as id from table1
oracle PL/SQL. I have almost finished this xml parsing task but their is one problem. Actually in our table there are more than 70-80 columns & due to that only I don't want to put the hard coded column name in my procedure, because if I will do that, the unnecessary procedure size will be increase(means line of code).Here is our procedure
Create or replace procedure loadMyXML(dir_name IN varchar2, xmlfile IN varchar2) AS l_bfile BFILE; l_clob CLOB; l_parser dbms_xmlparser.Parser; l_doc dbms_xmldom.DOMDocument; l_nl1 dbms_xmldom.DOMNodeList; l_nl2 dbms_xmldom.DOMNodeList; l_n dbms_xmldom.DOMNode; node1 dbms_xmldom.DOMNode; l_colName VARCHAR2(100); [code]...
We need to get the single node with class type ="1" from this XML as given below.At any point of time, there will be only one such tag with classType="1". Its position could be anywhere inside the "GroupDetails" Tag.ie, The query should get the tag irrespective of its position inside "GroupDetails".
<info groupId="128" classType="1"/>
Is there any way using EXTRACT function with 3 parameter? I tried but with failure.
with rec AS ( select XMLTYPE( '<connection value="0"> <GroupDetails> <info groupId="100" classType="0"/> <info groupId="128" classType="1"/>
