I have the following case when statement:
case when ts.wgt_kg / ((hgt_cm / 100) * (hgt_cm / 100)) < 18.5 then 'Underweight < 18.5'
when ts.wgt_kg / ((hgt_cm / 100) * (hgt_cm / 100)) between 18.5 and 24.9 then 'Normal 18.5-24.9'
when ts.wgt_kg / ((hgt_cm / 100) * (hgt_cm / 100)) between 25.0 and 29.9 then 'Overweight 25-29.9'
when ts.wgt_kg / ((hgt_cm / 100) * (hgt_cm / 100)) > 30.0 then 'Obese > 30.0'
end as BMI
How can i convert it into DAX? I tried to google it but I wasn't able to find anything useful. Can someone help me with that please.
Thanks
Try something along these lines:
BMI Category =
VAR BMI = ts.wgt_kg / ( ( hgt_cm / 100 ) * ( hgt_cm / 100 ) )
RETURN
SWITCH (
TRUE (),
BMI < 18.5, "Underweight < 18.5",
BMI < 25.0, "Normal 18.5-24.9",
BMI < 30.0, "Overweight 25-29.9",
"Obese > 30.0"
)
This will return the first condition that evaluates to true or use the last argument if none of the above are true.
This is my function
public function getRshow(){
$lats = $tenl[0]->latitude;
$longs = $tlog[0]->longitude;
$distance =$par_dis[0]->partner_distance;
$project = "SELECT * , (3956 * 2 * ASIN(SQRT( POWER(SIN(( $lats - latitude) * pi()/180 / 2), 2) +COS( $lats * pi()/180) * COS(latitude * pi()/180) * POWER(SIN(( $longs - longitude) * pi()/180 / 2), 2) ))) as distance
FROM `abserve_renterpost` having distance <= $distance order by distance";
$la=DB::SELECT($project);
$lara=array();
foreach ($project as $key => $v) {
$lara[]=(get_object_vars($v));
}
}
My query is working good if I run only the query, but if I converted my query for value and array format it's not working, error is displayed as below.

I noticed $lats was 27.7 which is odd.
try this

what am I doing wrong???
Thanks,
a few syntax errors, return type should be outside of input parameters and define type of input:
create or replace function time_gap (v_date1 in date, v_date2 in date)

EDIT:
You have to give us more of the error message. It's not saying anything. This works fine for me:

Have you created it without checking the syntax? Always check the syntax before doing stuff like that.
As per https://docs.oracle.com/cd/B12037_01/server.101/b10759/create_function.gif just in the first line:
you lack one of [IN][OUT][IN OUT] at every argument
you lack datatypes for every argument
return statement should be outside the parentheses.
At that point I stopped reading.

I cannot seem to figure out why it is not caching these results as the last_modified_date is not changing. i have set max item cache to 32m and memcache memory to 512.
I have rewrote my query to as below which gets cached but the createCommand way it does not

I am trying to create Brightness and Contrast filters similar to new Adobe Photoshop or Lightroom Brightness and Contrast filters. I am doing RGB -> XYZ - xyY conversion and with increasing pixel Brightness (Y) ( not linear increase, Brightness increase is calculated depending on pixels Brightness) and then converting back to XYZ and RGB trying to get as similar as possible values to test image that I used to increase Brightness in Adobe. I am not getting similar results as I think I am missing something, maybe gamma calculation or as images are in sRGB space some color space conversion, or I simple have bug in Color conversion code? So here are Color conversion function I used (in Objective-C) :
