I have a Column 'Status' which has values like Rework, Draft,Cancelled, Reviewed,Completed.
So in the prompt page i want a static choice with display value 'Treated' and 'Not treated'.
When the user selects 'Treated' then the "use values" should be 'Reviewed','Completed'
else if the user selects 'Not treated' it should be 'Rework',' Draft','Cancelled'. So how can we give multiple use values in static choice?
Please help!!!!
You need to create more advanced filter.
(?Selector? = 'Treated' and [Your column] in ('Reviewed','Completed'))
or
(?Selector? = 'Not treated' and [Your column] in ('Rework',' Draft','Cancelled'))
Where ?Selector? - you prompt variable.
Based on your comments, you need an if/then in your filter:
if (?Prompt? = 'Treated')
then ([column] in ('Reviewed','Completed'))
else
([column] in ('Rework','Draft','Cancelled'))
The OR suggestion below will work as well, I just personally find the if/then logic easier to read.

I would like to filter the output of show tables.
The documentation has one example on how to do this using result_scan(last_query_id()), but for me the example does not work:
show tables;
select "schema_name", "name" as "table_name", "rows"
from table(result_scan(last_query_id()))
where "rows" = 0;
-- SQL compilation error: error line 1 at position 8 invalid identifier 'SCHEMA_NAME'
The column SCHEMA_NAME is actually in the output of show tables,
so I do not understand what is wrong.
Best,

Run the following on your account and see what it is set to:
show parameters like 'QUOTED_IDENTIFIERS_IGNORE_CASE';
If this is set to TRUE, then it is ignoring the quotes in your query, which will then uppercase the column names, which won't match to the lowercase names of the SHOW output.
To resolve for your own session, you can run the following:
ALTER SESSION SET QUOTED_IDENTIFIERS_IGNORE_CASE = False;
You can also change this at a user or account level, if you wish. Setting this value to TRUE isn't recommended for the reason that you are running into.
You can reference the filter column using $<col_n> syntax (#8 for rows).
Example:
show tables;
select *
from table(result_scan())
where $8 > 5
That being said, your query worked for me.
I was needing to be able to pull a report based on who was logged in. For example, out of a group of salespeople, if Bob goes into this report and clicks on the Salesperson drop-down, I need him to only be able to see Bob as an available salesperson, not anyone else. I solved this by using the =User!UserID function in SSRS and it works beautifully.
Where I'm now having trouble is giving this functionality a CASE statement to allow an "Admin" view for managers to be able to go in and see Bob as well as everyone else. My current query looks like this and works as intended for only selecting that user's name from the Salesperson drop-down:
select SalesPerson_Name
from Salesperson
where salesperson_id = SUBSTRING(#user,14,20)
Here is what I'm attempting to use to override and give an 'All' type view for Admin level:
select Salesperson_name
from Salesperson
where case
when #user in ('DOMAIN\Brandyj','DOMAIN\jwilson') then 1=1
else SalesPerson_id = SUBSTRING(#user,14,20)
end
It does not like what I'm trying to do and gives me a
Incorrect syntax near '='.
Maybe I've been looking at this too long. Can someone spot something obvious?
You are close... just a minor change. You need the CASE expression to be evaluated on your operand of your SalesPerson_id column. CASE doesn't provide logical flow as you attempted to use it. Remember, it evaluates a set of boolean expressions to determine the result (which must be a single datatype).
I also opted for OR but you can still use IN if you'd like.
select Salesperson_name
from Salesperson
where
SalesPerson_id =
case
when #user = 'DOMAIN\Brandyj' or #user = 'DOMAIN\jwilson' then SalesPerson_id
else SUBSTRING(#user,14,20)
end
I'm trying to figure out a way to use WPDB to load a whole row or single cells/fields from another table (not the Wordpress-DB) and displaying them in a shortcode. I have a bunch of weatherdata-values, I need the latest row (each column is another data-type (temp, wind, humidity, etc) of the database for a start.
Sadly, the plugin that would do everything that I need, SQL Shortcode, doesn't work anymore. I found this now:
https://de.wordpress.org/plugins/shortcode-variables/
Though I still need to use some PHP/PDO-foo to get the data from the database.
By heavy copy&pasting I came up with this:
<?php
$hostname='localhost';
$username='root';
$password='';
$dbname='sensordata';
$result = $db->prepare(SELECT * FROM `daten` WHERE id=(SELECT MAX(id) FROM `daten`););
$result->execute();
while ($row = $result->fetch(PDO::FETCH_ASSOC))
{
$data = $row['*'];
}
echo $data;
?>
But obviously it's not working. What I need to get it done with WPDB?
kind regards :)
Just in case anyone else needs this in the future. I used this now:
//connect to the database
<?php
$dbh = new PDO('mysql:host=localhost;dbname=databasename', 'dbuser',
'dbpasswort');
//query the database "databasename", selecting "columnname" from table "tablename", checking that said column has no NULL entry, sort it by column "id" (autoincrementing numeric ID), newest first and just fetch the last one
$sth = $dbh->query("SELECT `columnname` FROM `tablename` WHERE `columnname` IS NOT NULL order by id desc limit 1")->fetchColumn(0);
//print the value/number
print_r($sth);
?>
By using "SELECT colum1, colum2,... FROM" You should get all the columns, could be that fetchColumn needs to be replaced with something different though.
I have a requirement to pull data in a specific format and I'm struggling slightly with the ROWTOCOL function and was hoping a fresh pair of eyes might be able to help.
I'm using 10g Oracle DB (10.2) so LISTAGG which appears to do what I need to achieve is not an option.
I need to aggregate a number of usernames into a string delimited with a '$' but I also need to concatenate another column to to build up email addresses.
select
rowtocol('select username_id from username where user_id = '||s.user_id|| 'order by USERNAME_ID asc','#'||d.domain_name||'$')
from username s, domain d
where s.user_id = d.user_id
(I've simplified the query specific to just this function as the actual query is quite large and all works except for this particular function.)
in the DOMAIN Table I have a number of domains such as 'hotmail.com','gmail.com' etc
I need to concatenate the username, an '#' symbol followed by the domain and all delimited with a '$'
such as ......
joe.bloggs#gmail.com$joeblogs#gmail.com$joe_bloggs#gmail.com
I've battled with this and I've got close but in reverse?!.....
gmail.com$joe.bloggs#gmail.com$joeblogs#gmail.com$joe_bloggs
I've also noticed that if I play around with the delimiter (,'#'||d.domain_name||'$') it has a tendency to drop off the first character as can be seen above the preceding '#' has been dropped from the first email address.
Can anyone offer any suggestions as to how to get this working?
Many Thanks in advance!
Assuming you're using the rowtocol function from OTN, and have tables something like:
create table username (user_id number, username_id varchar2(20));
create table domain (user_id number, domain_name varchar2(20));
insert into username values (1, 'joe.bloggs');
insert into username values (1, 'joebloggs');
insert into username values (1, 'joe_bloggs');
insert into domain values (1, 'gmail.com');
Then your original query gets three rows back:
gmail.com$joe.bloggs
gmail.com$joe_bloggs#gmail.com$joebloggs
gmail.com$joe_bloggs#gmail.com$joebloggs
You're passing the data from each of your user IDs to a separate call to rowtocol, which isn't really what you want. You can get the result I think you're after by reversing it; pass the main query that joins the two tables as the select argument to the function, and have that passed query do the username/domain concatenation - that is a separate step to the string aggregation:
select
rowtocol('select s.username_id || ''#'' || d.domain_name from username s join domain d on d.user_id = s.user_id', '$')
from dual;
which gets a single result:
joe.bloggs#gmail.com$joe_bloggs#gmail.com$joebloggs#gmail.com
Whether that fits into your larger query, which you haven't shown, is a separate question. You might need to correlate it with the rest of your query.
There are other ways to string aggregation in Oracle, but this function is one way, and you already have it installed. I'd look at alternatives though, such as ThomasG's answer, which make it a bit clearer what's going on I think.
As Alex told you in comments, this ROWTOCOL isn't a standard function so if you don't show its code, there's nothing we can do to fix it.
However you can accomplish what you want in Oracle 10 using the XMLAGG built-in function.
try this :
SELECT
rtrim (xmlagg (xmlelement (e, s.user_id || '#' || d.domain_name || '$')).extract ('//text()'), '$') whatever
FROM username s
INNER JOIN domain d ON s.user_id = d.user_id
I can limit the size of characters of table field in mysql as simple
SELECT NID,LEFT(BODY, 10) AS text FROM tablename
but how can i get the same result in codeigniter Active Record
I tried this code
$this->db->select('NID, LEFT(BODY,10)');
$query = $this->db->get_where('tablename');
but not working
is it possible to make that in codeigniter Active Record ??
I've been able make it work in Codeigniter using a syntax like this:
$this->db->select('NID, LEFT(BODY,10) BODY', false);
$query = $this->db->get_where('tablename');
as stated in: http://ellislab.com/forums/viewthread/201014/#940615
adding 'false' to select, avoids the automatic backtics
also, after left(BODY, 10), you must add the name the new chopped field will use:
select('NID, LEFT(BODY,10) BODY'
otherwise, Codeigniter will output an Undefined property error.
I hope it works!
