SELECT LIST throws an error for the WHERE CLAUSE
Hi allI am struck with what looks like a trivial mistake, but I don't know how he moved. I'm new to Apex (3.1). I'm experimenting with. I have Oracle 10 g on Windows.
I have a drop-down list item in one of my pages (SELECTION list). I'm trying to display a few items he dynamically (depending on the logged-in user). I've defined this SELECT LIST and entered into the following query in "list of values".
select enrolled_course display_value, course_id return_value
from COMP_LIST
where stu_id = :APP_USER
order by 1
I got the following error.1 error has occurred
LOV query is invalid, a display and a return value are needed, the column names need to be different. If your query contains an in-line query, the first FROM clause in the SQL statement must not belong to the in-line query.
Then I tried the step by step instructions of "Oracle® Application Express Advanced Tutorials-version 3.1.2 - E10497-02. With the help of creating list of values such as creating separately. That too, I got the same error.I'm doing it wrong I suppose. Please correct me. Thanks in advance

Hello
The principle should be the same. The value of the text element would be stored in the session, then you can use: P1_APP_USER (or what is called the element) instead of: APP_USER. To be absolutely certain, you can create a page process to fill the element having the value of APP_USER point process before conditional header field is null. Or you could create a component of demand that populate once the connection and then use it everywhere where you have - I tend to do something like this with user-specific information that is stored in my tables from the user.

Try adding conditions to clause "and" stored in the table for the where clause, unknown syntax
I am trying to add additional segments to the 'where' clause, and I don't know exactly how to proceed. I am currently using another table to search for keywords and sometimes there aren't everything. I use this table containing the key words to search the description and associate a symbol with a path.
The code loops through the keywords with the keywords most associated and try to find links to a symbol then excludes those and search for symbols that correspond to those with less keywords and all. I am able to do this with 6 queries and manually changing the arguments, but I want to loop together so that if the changes need to be made in the future, I won't need to go digging in the code.
Thanks, but that's ok. I already have a solution for this.

NVL selection list does not not on the place where clause in query
Ok. APEX 4.2...
Im having problems with my selection lists and NULL values... I see that it has come time and time again...
I have a tabular presentation, with a query based on a selection list. The selection list has the ability to '- Show All -'... The value of the selection list is a number, and the display is words... (for reference the LOV query is: select status, batch from pmt_stat_lookup by 1)
Initially I had problems with null and invalid numbers like ' display Null = 'Yes' and the problem of null % ', so have used the code in this blog to remove the NULL values... Display Null = & amp; #34; Yes & amp; #34; and the problem of null % | Inside Oracle APEX by Patrick Wolf
Then in the application of my report, I have a where clause clause that checks the value of the selection list... WHERE batch = nvl(:P11_STATUS_SELECT,STATUS_ID)
everything works almost fine, and I can choose a status, or I choose - see the All-, but the query will not include the lines where the State is null.
(I also see that maybe I should be, use the case statement instead of the NVL on where clause, but not sure of the syntax. In addition, NVL was used somewhat in the different reports in the application...)
For reference, the code of the old blog that I as a process page is:
BEGIN
FOR rItem IN
(SELECT NOM_ELEMENT
OF APEX_APPLICATION_PAGE_ITEMS
WHERE APPLICATION_ID = TO_NUMBER(:APP_ID)
AND PAGE_ID IN (TO_NUMBER(:APP_PAGE_ID), 0)
AND LOV_DISPLAY_NULL = 'Yes'
AND LOV_DEFINITION IS NOT NULL
-change here
AND LOV_NULL_VALUE = '% null | '%'
)
LOOP
IF V (rItem.ITEM_NAME) = "% null | '%'
THEN
Apex_Util.set_session_state (rItem.ITEM_NAME, NULL);
END IF;
END LOOP;
END;
Thank you very much

Beginner: Get on the WHERE clause syntax error in SELECT
I am very new to php and mySQL. Use DW master/detail to generate Basic code I need. One thing I have to do is to modify a select statement in the master to include a WHERE clause to limit the selection to a particular value in a field.
I get a syntax error with the select statement in the WHERE clause, I add to the map.
It's the part of the error message showing the location of the error:
"WHERE group = 'Community' LIMIT 0, 10'"
Php that generated the select is:
$query_maps = "SELECT * FROM tblmaps ORDER BY tblmaps.» DispSeq ';
$query_limit_maps = sprintf ("%s WHERE group =' LIMIT %s %d, %d", $query_maps, $selectGroup, $startRow_maps, $maxRows_maps);
This approach to create the select statement is on the generated code for the master page. He added the LIMIT clause. I didn't add the ' WHERE group = '%s' and the variable $selectGroup, which comes from the old code.» You can see that the $selectGroup variable is equal to the "community: group.»
I scanned the web to see what syntax error, I could do, but haven't found anything that explains it.
The resolved full select statement is:
SELECT * FROM tblmaps ORDER BY tblmaps. WHERE DispSeq = 'Community' LIMIT 0,10 group
What I don't see?
Tom
The group is a reserved word in MySQL. You could probably put single quotes around it, but I suggest to rename this column. Do not use reserved words for column names.

T/t with the WHERE clause using a list breaks
Hello, all,.
I have a project where I need to use a list as part of the WHERE clause for a t/t, and it is breaking. I don't know what I'm doing wrong.
For some pseudo-code, do I have a complete query of a database called 'people '. A list of values for the t/t with the first query; the second query is my t/t:
<cfquery name="getDIR" datasource="#request.THISDSN#"> SELECT thisName dir FROM orgs WHERE thisID in (<cfqueryparam value="#form.org#" cfsqltype="cf_sql_varchar" list="yes" />) </cfquery> <cfquery name="people" database="people"> SELECT colA, colB, colC, colD FROM people WHERE 1=1 AND ( div IN (<cfqueryparam value="#valueList(getDIR.dir)#" cfsqltype="varchar" list="yes" />) OR dir IN (<cfqueryparam value="#valueList(getDIR.dir)#" cfsqltype="varchar" list="yes" />) ) </cfquery>
I get the error message is "t/t syntax error: encountered" div IN \'thisValue\' ".» Incorrect conditional expression, waiting for one of [as | null | between | in | comparison] condition. »
Can support _not_ QoQ lists of WHERE clauses?
V/r,
^_^
SMH - so much... I just found.
I forgot to give the lists in the second query bracket.
(The pseudocode was manually typed, since my dev system is isolated from the internet, and I added the in my pseudo code when they were not in my original code.)

Execution of statement of UPDATE for the whole table even when the WHERE Clause is presentation
Hi friends,
I have a problem in a stored procedure where I wrote an update with a where clause clause statement. At some point only one line should be updated according to the unique identifier in where clause.

Types of errors for the JCA adapters
What are the types of failures (the local part name) in the namespace: http://schemas.oracle.com/sca/rejectedmessages .
I want to handle errors for the FTP adapter for rejected messages. But I don't know what are the types of faults defined for the FTP (adapter JCA) adapter.
Can you please tell me the document where it is documented so that I can proceed to develop Faulthandler to FTP adapter.
11g, I need to use fault - policies.xml and fault - bindings.xml.
I need to set the faultname inside the fault - policies.xml file of the above information.
Thank you
ChristelleHi Dani,
The name of the local part should be the same as the service name that is to say when you define an adapter two files are generated
.wsdl and files.jca.So than this should be used as the name of the local party for the fault - policies.xml and at fault - bindings.xml, it should be as below.
xmlns = "http://schemas.oracle.com/bpel/faultpolicy."
xmlns: xsi = "http://www.w3.org/2001/XMLSchema-instance" >

DECODE does not work in the WHERE clause when subquery returns more than one line
Hi gurus,
I want to write a query against the table CCENTERS (Script given below) and wait for the following result:
1. in the transition from a value of 0 for the ID, it returns all the rows in the table.
2. in the passage of one value other than 0, it returns the row corresponding to the given value and all its records of the child.
CCENTER has parent-child relationship in the column ID and the BASE. I use a query with the DECODE function. but the function in the WHERE clause is not capable of managing the subquery with multiple lines of DECODE.
