Using "between" for the literals inside the 'where' clause

Hi all
I have run the following queries in 10.g HR XE diagram example:
The first query is limited by characters between 'I' and 's', where the second query is limited to words between "IT" and "Sales".

My question is, how did the first query will not return not row "Sales" as it does in the second? I don't understand not how 'between' works on string literals. Help, please.

Kind regards
Valerie

DEPARTMENT_NAME
------------------------------
Retail Sales
Sales

13 rows selected.

Imagine how these words are ordered in an encycopedia or a thesaurus.

1. I have
2.
3 IT Helpdesk
4. technical support
5 manufacturing
6 marketing
7 AC
8 operations
9 payroll
10. public relations
11 purchase
12 recruitment
13 S
14 sales
15. management system

"S" is ordered before "Sales". Between includes everything including the lower and the upper limit (row 1-13). It does not include things in order AFTER the upper limit (line 14 ++).

So, if you want to find everything that begins with "S", then you have several options.

(1) show all after including 'I' but before the "T" (not including T)

select department_name
from departments
where department_name >=  'I'
and department_name < 'T'
order by department_name;

or
(2) show all what the first letter between "I" and "S".

select department_name
from departments
where substr(department_name,1,1) between 'I' and 'S'
order by department_name;

Almost always, I would choose the first option. Usually it's faster as a clue to the name of the service can be used if there is a.

There is a third option. But it's kind of stupid and incomplete. You could add the last string you can imagine as the upper limit of between it the function.

select department_name
from departments
where department_name between 'I' and 'Szzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz'
order by department_name;

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.

SELECT LIST throws an error for the WHERE CLAUSE
Hi all

I 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.

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.)

DECODE inside the WHERE clause

Hi all:

I can't get the DECODE statement to work inside my WHERE clause. I have read the information on
Tahiti.Oracle.com
http://download.Oracle.com/docs/CD/E11882_01/server.112/e17118/functions049.htm#i1017437

But still can not get it to work. Initially, I had he works as dynamic SQL and then run that string, but I am not allowed to use dynamic SQL statements and to do 'Real' PL/SQL.

I have the following WHERE clause (more info after the WHERE clause)

WHERE 
     a.ebiz_asn_no(+) = te.ebiz_cntrl_no
     AND w.ebiz_work_no(+) = te.ebiz_cntrl_no
     AND o.ebiz_ord_no(+) = ebiz_cntrl_no
     AND t.ebiz_trailer_no(+) = te.ebiz_trailer_no
     AND ms.ebiz_sku_no(+) = te.ebiz_sku_no 
     AND NVL(ms.ebiz_sku_no, -1) = NVL(p_SKU, nvl(ms.ebiz_sku_no, -1))
     AND tl.ebiz_lp_no(+) = te.ebiz_lp_no 
     AND NVL(te.ebiz_lp_no, -1) = NVL(p_LP, nvl(te.ebiz_lp_no, -1))
     AND eu.ebiz_user_no(+) = te.act_ebiz_user_no 
     AND NVL(te.act_ebiz_user_no, -1) = NVL(p_UserID, NVL(te.act_ebiz_user_no, -1))
     AND NVL(te.begin_location, '~') = NVL(p_BeginLocation, NVL(te.begin_location, '~')) 
     AND NVL(te.end_location, '~') = NVL(p_EndLocation, NVL(te.end_location, '~')) 
     AND te.comp_id = p_CompID 
     AND te.site_id = p_SiteID 
     AND INSTR('' || p_TaskType || '', te.task_type) > 0 
     AND NVL(task_priority, -1) = NVL(p_Priority, NVL(task_priority, -1)) 
     AND NVL(te.ebiz_cntrl_no, -1) = DECODE(te.task_type, 'IULD', DECODE(p_Order, null, te.ebiz_cntrl_no, ebiz_po2asn.get_ebiz_po_no(p_Order)), NVL(p_Order, NVL
                       (te.ebiz_cntrl_no,-1)))
     AND NVL(te.batch_no,'~') = NVL(p_Batch, NVL(te.batch_no, '~'))
     AND NVL(te.ebiz_wave_no, -1) = NVL(p_Wave, NVL(te.ebiz_wave_no, -1)) 
     || whereClauseStatus 
     || whereClauseFromDate 
     || whereClauseToDate;

As you can see, initially I was adding values of "whereClauseStatus, whereClauseFromDate, whereClauseToDate" and it has been defined with the following PL/SQL code:

     IF(p_TaskStatus = 'C') THEN
          -------------------------------------------------------------------------------------------
          --     Set From Date Clause
          -------------------------------------------------------------------------------------------
          IF(p_FromShipDate IS NOT NULL) THEN
               whereClauseFromDate := ' AND TRUNC(te.act_end_date) >= TO_DATE(''' || p_FromShipDate || ''',''MM/dd/yyyy'') ';
          END IF;
          -------------------------------------------------------------------------------------------
          --     Set To Date Clause
          -------------------------------------------------------------------------------------------
          IF (p_ToShipDate IS NOT NULL) THEN
               whereClauseToDate := ' AND TRUNC(te.act_end_date) <= TO_DATE(''' || p_ToShipDate || ''',''MM/dd/yyyy'') ';
          END IF;
     ELSE
          -------------------------------------------------------------------------------------------
          --     Incomplete and All statuses are filtered on the currdate
          -------------------------------------------------------------------------------------------
          -------------------------------------------------------------------------------------------
          --     Set From Date Clause
          -------------------------------------------------------------------------------------------
          IF(p_FromShipDate IS NOT NULL) THEN
               whereClauseFromDate := ' AND TRUNC(te.currdate) >= TO_DATE(''' || p_FromShipDate || ''',''MM/dd/yyyy'') ';
          END IF;
          -------------------------------------------------------------------------------------------
          --     Set To Date Clause
          -------------------------------------------------------------------------------------------
          IF (p_ToShipDate IS NOT NULL) THEN
               whereClauseToDate := ' AND TRUNC(te.currdate) <= TO_DATE(''' || p_ToShipDate || ''',''MM/dd/yyyy'') ';
          END IF;
     END IF;
     

     IF (p_TaskStatus = 'I') THEN
          whereClauseStatus := ' AND act_end_date IS NULL ';
     ELSIF (p_TaskStatus = 'C') THEN
          whereClauseStatus := ' AND act_end_date IS NOT NULL ';
     ELSE
          whereClauseStatus := '';
     END IF;

I have serious problems getting the DECODE statement to replace the three variables in the annex.

Any help would be greatly appreciated.

Thank you

The reason why you see directions is not available, it's that for cards of Apple, turn-by-turn directions is not a feature that is available in the Qatar. You can search for places and satellite imagery

Well not much description required in this case. I was using firefox for the first time on a mac and so was trying new things with this version of firefox. Just got stuck with these separators xtra... Can't find a way to get them off of my bookmarks toolbar...

You can open the Bookmark Manager (Bookmarks > show all bookmarks) and go to the Favorites bar folder in the left pane.
You can then remove the separators in the right pane.

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.

But what is happening is that the Update statement is getting executed for all rows in the table to neglect the WHERE clause. I don't get any idea of why this is happening. Here is the stored procedure and the update statement is BOLD:-

CREATE OR REPLACE PROCEDURE MDMADM.proc_MDM_InsertCntryDetails

Thank you

WHERE mdm_code = mdm_code

This will always be value true - similar to WHERE 1 = 1.

You typed it wrong or is the same as the variable column name? If they are the same test rename one of them.

In the WHERE clause string variable
I have the procedure

CREATE OR REPLACE PROCEDURE proc1 (p_1 IN varchar2)
IS
BEGIN

DELETE FROM TABLE1
WHERE
Col1 = '@p_1. '
;

Dbms_output.put_line (number of rows sql %);

COMMIT;

EXCEPTION
WHILE OTHERS THEN
ROLLBACK;
RAISE_APPLICATION_ERROR (-20000, SQLERRM);
Proc1 END;
/

You will need to pass a string input parameter to the procedure. This string is applied to the WHERE clause. The foregoing does not work correctly the value of @p1 is in the WHERE clause. The value passed to the stored procedure does not run.

Please let me know the solution. I have to use BIND variables only.

Thank you

Thank you all. Yes, the underside of the works.

DELETE FROM TABLE1
WHERE
Col1 = p_1

PS: Both COL1 and p_1 are string values. Would like to know how it works with out the quotes because it is a string.

In addition I would like to follow the number of lines executed in each statement. Preference will have to use sql % rowcount. Are there other alternatives. Please let me know. Thanks in advance.

Oracle 'knows' that the variable p_1 is a varchar2 data type and that col1 is a varchar2 data type, so he makes a comparison between them strinf. This is how variables work in any programming language that I am aware. The only time that you must provide a value is when you use a literal value (for example in an assignment variable, or as a parameter of a procedure).

If you need to know the number of deleted rows, then sql % rowcount is the only sensible option. Just be aware that you need to get the value before committing yourself ot other options of SQL.

by the way check box values in the WHERE clause

Hello
I created a data block - 'CONTACT' (block of data in database)
and has an element of database - 'Code', 'Descr '.
The number of records displayed has the value 5.
When enabled - value 'Y '.
Value when disabled - n
Box mapping of other values - "unchecked."

I write the code inside "WHEN the BUTTON PRESS. My main goal is to return the number of records from
According to several conditions and one among them is the CODE which can be single or multiple based on the checked checkbox.
The requirement is when I check one or more boxes, I should pass the "Code" element values in the WHERE clause.
I tried to use the simple loop but things havmt worked as shown below.
The next_record refers to the COCHEE BOX as well, and thus return all the eventhough lines if it is not checked.
----------------------------------------------------------------------------
-LOOP
IF: contact.cb = 'Y' THEN
LOOP
IF p_where is null then
p_where: =: contact.code;
on the other
p_where: = p_where | «, » || : contact.code;
end if;
When the output: system.last_record = "TRUE";
next_record;
END LOOP;
end if;
-END LOOP;
MESSAGE ("p_where :'|| p_where);
MESSAGE (' ');
END;

------------------------------------
And even if I write the LOOP before the first CASE, it returns me the current value and move to the last record.
Please suggest

Try something like this:
```
FIRST_RECORD;

LOOP

  IF :contact.cb = 'Y' THEN
    IF p_where is null then
       p_where := :contact.code;
     else
       p_where := p_where ||','||:contact.code;
     end if;
   END IF;
  exit when :system.last_record = 'TRUE';
  next_record;
END LOOP;

-- END LOOP;
MESSAGE ( 'p_where :'||p_where);
MESSAGE (' ');

END;
```

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.

Using "between" for the literals inside the 'where' clause
