Comparing every field record

Applications Grid / Reports
#1

I am new to this forum but learn scriptcase for months now still can not get what i want.
“I have a grid application with records of weight with 10 records, I would like to compare each weight by the difference of less than or equal to 30grams and match them as paired.” (needs to be sorted out first in decending order)
I have the following records:
mangoes 130grams
banana 500grams
apple 150grams
grapes 530grams
the result should be like
grapes 530grams 1
banana 500grams 1
apple 150grams 2
mangoes 130 grams 2

Please help me as one of my project in class.

I think you need to look at the sql to select the required data. You need to select count(*) and apply a break on fruit. In the where you need to specify the match. I suggest you try to create a valid sql statement in the database of choice until it returns the required data. Then you can start coding in scriptcase.

First I want to sort my database by grams.
I have a table called fruits with the files on grams. I want to to sort grams in descending order
I know the SELECT command in SQL like
SELECT “weight”
FROM fruits
ORDER by DEC
But how can i insert it to my scriptcase under onrecord or onload?
so that the grid application will display all fruits with weight in descending order?

Needs some help with this.

#5

how can i execute this statement in grid application so that i will sort my table

$sql = "SELECT weight
FROM weight_sub_table
ORDER BY
weight DESC ";

It doesnt affect the grid display, i know the is missing command but how can i continue with this?

Put your SQL Code in Grid / SQL, not in onRecord or onLoad …

Thank you very much for that little sql trick, I can sort the table, and i can see my data sorted. thanks again RHS

After the data has been sorted I placed the SELECT command onrecord event to compare the each record on my table, I can compare the first field but I can not see the comparison on the second field. I know a little idea on how to do it on the own way, but in scriptcase, i can not do this

My problem is this comparison:
I want to compare the each field record in weight and compare with the next record if their difference is <= to 30
if this is true match number will be inserted on both record field.
Then the third and the fourth record will then be compared if their difference is <= 30
if this is true then match number will be inserted on both record field, and so on.

To do this, I use the code: but only the first and the second record was compared and all filed was inserted number 1.

$sql=(“SELECT weight,match_num
FROM weight_sub_table
ORDER BY weight DESC”);

sc_lookup(ds,$sql);

 $first = {ds[0][0]};
 $second ={ds[1][0]};

/compute of the difference/
$diff = $first - $second;

/if statement/

if($diff <= 30 )
{
$match_num = $match_num + 1;
{ds[0][1]} = $match_num;
{ds[1][1]} = $match_num;

   }

else
{
sc_alert(“needs to proceed to another record”);
exit();
}

What i really want is to have a table with this picture1 and the result will be in this picture2

I just manipulated the file.

Thanks again, please help me with this.
