I am trying to make a query for approval of documents, where the result display the name and signature with date. How can I get the date for two people approving the document?
Select Uname
case when stepcode=1 then 'approver1' end as 'name of person'
case when stepcode=1 then 'approver1' end as ' date of signed noted'
case when stepcode=2 then 'approver2' end as 'date of signed approved'
from table
I tried this, but only one result showed up. Only the name, signature and date of the first approval displayed.
We can only answer this by making some assumptions:
the field stepcode denotes what stage of the sign off process the record is at
value of 1 means noted and value 2 means approved. A value of 0 means nothing has happened yet
approver1 and approver 2 are NULL if the action has not yet taken place
If all of the above is true, then there should be no requirement to have a CASE statement for the fields... just including the fields within the SELECT statement will bring the values through if they have been completed.
Some validation of data might be required here though if you are not getting the results you are expecting. Running some rough counts for each of the steps and for where they have values in the approver fields would help to make sure your code is working. The following should give you something to work with:
SELECT
stepcode
COUNT(TableID) AS NumberAtStep
FROM table
GROUP BY stepcode
Using these counts, you can then run your statement without the CASE statements and run a manual count to ensure you are seeing the right number of records with the relevant populated columns for each step.

I have a list of leads data.
The table has a lot of infos like date, name, email, mobile number, etc.
However, some of these leads are duplicates: the same person generated more than one lead
What i want to do is to remove the duplicate leads.
The problem is, to be considered a duplicated lead, the email or the mobile number must appear in more than one row, in a time interval of 30 days.
And only those who come next must be considered duplicated. The first one is always a not duplicated lead.
E.g.
1) If Jones generated a lead in 01/01/20 with his email abc#abc.com and then generate another lead 10 days after, in 10/01/20. The first lead is a single lead (not duplicated) and this second lead must be considered duplicate.
2) If Maria generated a lead in 01/01/20 with her email xyz#abc.com and then generate another lead 40 days after, in 10/02/20. The first lead is a single lead (not duplicated) and this second lead also must be considered single (or not duplicate).
To mark the lead as duplicate or not, i want to generate a new column with the time between the last lead of the same person (same email or same mobile number)
Then generate a new column with the label "Duplicate" or "Not Duplicate" based on the time showed on the last column. If its > than 30 days, that is a single lead. Otherwise (<30 days) is a duplicate lead.
E.g picture:
Can someone please help me on how to do that?
Getting the lag/lead data is not very straight forward in Power BI. You will have to use a combination of EARLIERand some aggregate function to get the specific result. For your specific scenario, the following calculation might work:
Day Difference =
VAR name1 = 'Table'[Name]
VAR Lastdate1 = MAXX(FILTER('Table','Table'[Name]=name1 && 'Table'[date]<EARLIER('Table'[date])),'Table'[date])
RETURN
IF(
DATEDIFF(Lastdate1,'Table'[date],DAY)=BLANK(),
100,
DATEDIFF(Lastdate1,'Table'[date],DAY))
Once the column is created, you can filter for all records <=30 to get the result you are looking for. I have replaced the blanks with 100, so that the original records don't get removed when applying the condition.
If you are looking for the "Tag" value, then the following calculation will get you the tag values directly:
Tag =
VAR name1 = 'Table'[Name]
VAR Lastdate1 = MAXX(FILTER('Table','Table'[Name]=name1 && 'Table'[date]<EARLIER('Table'[date])),'Table'[date])
RETURN
IF(IF(
DATEDIFF(Lastdate1,'Table'[date],DAY)=BLANK(),
100,
DATEDIFF(Lastdate1,'Table'[date],DAY))<=30,"Duplicate","Single")
I am using MySQL in such a way that the user enters a date and flights appear on that day.I was too lazy to put many dates so what I did was made certain flights run on certain days.
The table planes contains many columns out of which dtd(column containing many days of type varchar(50)) .
One record(in dtd) is Monday, Tuesday
The user enters the date 2018-12-03 which is a Monday.
My problem is how do I extract only the record which has Monday?(like the monday,Tuesday one)??
I tried select.....where instr(day(2018-12-03),dtd)<>0 but I realised that instr gives 0 in 2 cases
1. the character(s) is not present in the record or
2.occurence is at the beginning.
Like instr(h,hello) and instr(a,hello) gives 0.
Please help
I suggest that you use the LIKE operator.
For more info about it please check this link: SQL Like Operator
To solve your problem, you can try the following:
SELECT ...
WHERE dtd LIKE CONCAT('%', day(2018-12-03), '%');
In this case, you will get all the rows of the table, where the value of the field dtd contains the value of day(2018-12-03).
Hope this helps!
I am attempting to maintain and fix a horribly out-of-date CRM designed by an ex-employee ~4-5 years ago in Access 2007. I have brought it into Access 2013 and fixed a ton of stuff up, but I am still running into many problems.
I spent a good 4 hours today attempting to figure out why certain values didn't line up. These values were being pulled from a SELECT statement on a Combo Box over a stored Query which simply returns a table with a few extra rows. Great.
However this value (a number) doesn't appear to correlate with what we expect. I enter in one value, save the ticket, and a completely different value gets stored into the table. Opening up the ticket, I see the value that I expect. Digging deeper, I found the following difference:
Set value_1 = Me.RegistrationID // What's being stored in the table
Set value_2 = Me.RegistrationID.Column(0) // What we expect
Surprise surprise! This is a Combo Box and some value is being stored in the table. The Control Source is "RegistrationID" and the Row Source is the query in question.
However I do not know what it is! This specific value correlating to the Combo Box appears to pull the correct data when we later open the tickets. However I have a strong feeling that this could be why many tickets from before one of the rows was deleted all appear to have invalid RegistrationID's.
How badly can this break?
How easily can we correct tens of thousands of tickets?
How can I fix this to store the correct value?
This is what I expect is happening.
Your combo box row source is based on a Select query which returns and displays multiple rows. For example:
Select RegistrationID, CustomerID, CustomerName From MyTable;
The Control Source for the combo box is bound to RegistrationID which is part of the Forms Record Source.
The issue is the bound column. If we set the bound column in our example to 1, then we get the behavior your are describing with:
Set value_1 = Me.RegistrationID - Set's value to CustomerID (may appear correct)
Set value_2 = Me.RegistrationID.Column(0) - position 0 from our query (RegistrationID)
Further building on our query example, you can say:
Me.TextBox1 = Me.RegistrationID.Column(0) - RegistrationID
Me.TextBox2 = Me.RegistrationID.Column(1) - CustomerID
Me.TextBox3 = Me.RegistrationID.Column(2) - CustomerName
The RegistrationID is what normally should be stored in the table.
As long as your form shows any values that directly relate to this RegistrationID you're fine.
I would start by checking to see under the format setting to see if column widths are set properly and I would also check under the data section to see if the bound column is correct. I might also throw in an after update macro/vba sub routine that saves the record. Hope this helps.
i have a stored proc returning inventory amounts between a start and end date.
the QTY field shows on-hand inventory adjustments by date, either IN or OUT.
i have a "run balance" field that needs to show the total QTY each day. if the InOut field is 0, it's QTY in. if it's a 1, its QTY out. the values reflected in In and Out are coded that way.
EXAMPLE. if i start on 4/1/14 with 5216. then 1061 of product is made on 4/1/14 i need the run balance to take 5216 and add 1061 on the next line. the next line should read 6277 instead of 1061. then if some is shipped, take 6277 and subtract, and so on.
i tried the running value on QTY, but it just repeats the QTY. doesn't calculate anything.
=RunningValue(Fields!QTY.Value,Sum,"Details")
i tried to post an image of my report preview, but i don't have the reputation ;-)
any help would be MUCH appreciated.
EDIT: OK, i tried this code block:
= Switch(RunningValue(Iif(Fields!InOut.Value = 0, Fields!QTY.Value,0),Sum,"Details"),
RunningValue(Iif(Fields!InOut.Value = "1", Fields!RunBalance.Value - Fields!QTY.Value,0),Sum,"Details"))
and i am getting a 0 on the sum fields, and #Error on the subtraction fields. but, i think this is more the direction i need to go (i hope)....but i am still not getting it.
There are a couple of things to look at here.
First, you specify the Scope of "Details" in your RunningValue expression... By default this group will have no grouping value, i.e. each row in the dataset will be in its own group. Which means the RunningValue will only ever be applied to one row only. Change the Scope to "MyDataset" or Nothing, whatever is appropriate.
Secondly, you need to consider how the InOut field affects the RunningValue.
I have created a simple Dataset:
And a simple table:
The Balance expression is:
=RunningValue(IIf(Fields!InOut.Value = 0, Fields!QTY.Value, Fields!QTY.Value * -1)
, Sum
, Nothing)
You can see this changes the Scope from your original statement, and also applies a multiplier to QTY based on InOut.
Works OK for my sample data:
close to 3 months into powerbuilder classic 12.5 and sql server 2008 and am working out well. I am creating a car hire system using car registration_number as the primary key.
i need to capture the car's details and make sure that the registration_number is not available. The code here is not working but that of the capacity works out...
What is wrong with the code? please give another way that works.
if i dont click on the column 'capacity' and click on save, the program goes on and saves the record even when it is an empty field. how to i avoid that.
String car_registration_number
car_registration_number = dw_newvehicle.GetItemString( Row, "registration_number" )
long error_code = 0
string column
column = dwo.name
choose case column
case "registration_number"
if data = car_registration_number THEN
messagebox("validation error", "You cannot available regno")
error_code = 1
end if
case "capacity"
if integer(data) >10 then
messagebox("validation error", "a car's capacity cannot be more than 10...")
error_code = 1
end if
end choose
return error_code
Instead of GetItemString at the top, you would need to do one or two finds in the DataWindow for the registration number in data. If the first find returns 0 you are OK. If it returns the current row, you need to search from row to the last row unless you are on the last row, which you may well be if you are inserting. However, I wouldn't do it that way because it won't work in a multi-user environment. Instead, you should go ahead and insert the row and then if you get a duplicate key error, tell the user the registration number is already in the system. If the user is going to enter a lot of data you could try to SELECT the registration number from the database when the user enters it, but you still have to be able to handle the duplicate key error.
I don't understand what kind of check you are doing here for registration_number : you are getting the current value of the column in the DW into car_registration_number then you are comparing to the value that was modified (the code comes from the itemchanged event ?). Do you expect to enter a value that is different from the current one ?
Also beware of the GetItemString if the type of the column is not a text (as it is called ..._number) as PB may crash, return some null value or silently fail (depending on the PB mood of the moment ;). If you get a null value, your if check will always fail.
If you want to get numerical values, use GetItemNumber instead.
you can set the capacity column to be not null in you database. When saving the DW, you will get an error telling that there is some required value that was not set.
A better idea would be to iterate in the UpdateStart event on the columns that are member of the table primary key and to check if they are set or not.
To write some dynamic code, you can get at runtime the columns from the DW by describing the datawindow.column.count then checking the pk members with #1.key (replace #1 by #2, #3, ...) if the check must be done on that column.
