Sql:
concat(Discount,'% ',if(Net_Deferred=0,' Spot Cash',Net_Deferred, ' months deferral'))
The issue:
if(...Net_Deferred, ' months deferral'..
The comma that concatenate the 2 strings throws an error because if statement only works on 2 commas (true or false)
The result should look like this:
If(Net_Deferred=0) : Spot Cash
else : 24 months deferral
value 24 comes from Net_Deferred field.
Question:
How to concatenate field inside concat with if else statement?
You can use concat again
IF(Net_Deferred = 0, " Spot Cash", CONCAT(Net_Deferred, " months deferral"))

How can I sort the values returned from a LookUpSet function inside a Join function?
Example data:
TransNo MasterTran Item Category ModifierLevel
1001000 1001000 ItemA CategoryB 0
1002000 1001000 ItemB CategoryC 1
1003000 1001000 ItemC CategoryC 1
End result I'd like to get is "CategoryB ItemB ItemC". When I use the following combination of Join and LookUpSet, I end up getting "ItemB CategoryB ItemC".
=Join(LookUpSet(Fields!MasterTransNo.Value, Fields!MasterTransNo.Value, Iif(Fields!ModifierLevel.Value > 0, Trim(Fields!ItemDescription.Value), Trim(Fields!CategoryDescription.Value)), "LineItemDetails"), " ")
This is an expression on a cell in a table. The Row Group is set to Group on TransNo, sort by TransNo. I've tried a variety of different approach to sorting for the group, but always get the same result.
Any ideas on how I can force the order of data from LookUpSet so that it's joined in the order I want?
I ended up figuring this out by seeing other questions looking to pull distinct values only from the Join(LookUpSet()) functions and modifying it. This code is based off the useful answers from this other SO question.
Go to Report Properties
Enter the Code editor and past the following function into the Custom Code box:
Public Function JoinSortAlpha(arr As Object(), delimiter As String) As String
System.Array.Sort(arr)
Dim result As String = String.Empty
For i As Integer = 0 To arr.Length - 1
If Not arr(i) Is Nothing And arr(i) <> String.Empty Then
If result = String.Empty Then
result = arr(i)
Else
result = result + delimiter + arr(i)
End If
End If
Next
Return result End Function
Go to your expression and replace the Join() function with your new function by calling JoinSortAlpha(). My new expression looks like this:
=JoinSortAlpha(LookUpSet(Fields!MasterTransNo.Value, Fields!MasterTransNo.Value, Iif(Fields!ModifierLevel.Value > 0, Trim(Fields!ItemDescription.Value), Trim(Fields!CategoryDescription.Value)), "LineItemDetails"), " ")
Here's a breakdown of what the function is doing:
Create a new function called JoinSortAlpha which will have values passed into it from the expression. In this case, the values from the LookUpSet() function.
Sort the array passed from the function's argument. It's this sort that will make it alphabetical by default.
Create a String object called result to pass the final values to.
Evaluate the array arr and write a value to the result string for each value contained in the arr array. Values in an array are given a numeric value starting at 0 and increasing by 1. Here, we're telling the array to continue populating the result string from the first value in the array (at 0) until the last value in the array which is determined by the length of the array minus 1 (because the array starts at 0 rather than 1).
If your LookUpSet() function doesn't return any values, SSRS will show an error if we don't account for that in this JoinSortAlpha function. To deal with any potential blanks being returned, we're using an If statement to determine if the string is empty in which case it just returns nothing. Otherwise, it will return the value plus the delimiter from the end of the function (a space " " in my case).
Is there any function in MySQL where I especifies the concurrences numbers for the search?
Example:
lcString = "My name-is-Harry-Potter"
In Visual FoxPro you can use this:
?AT('a',lcString,1) && where 1 means "get me the first concurrence"
OutPut = 5
Or
?AT('-',lcString,3) && where 3 means "get me the third concurrence"
OutPut = 17
I was looking for a similar function in mysql but I can't find it.
Thank you all...!!!
You can use SUBSTRING_INDEX and LENGTH MySQL functions to achieve that. This is what MySQL's documentation says about SUBSTRING_INDEX:
Returns the substring from string str before count occurrences of the
delimiter
So, you can wrap that inside LENGTH to get the occurrence, e.g.:
SELECT LENGTH(SUBSTRING_INDEX('My name-is-Harry-Potter', 'a', 1)) + 1
SELECT LENGTH(SUBSTRING_INDEX('My name-is-Harry-Potter', '-', 3)) + 1
I'm expecting only the names to appear on the calendar if they exist and nothing if they don't.
I created an expression where it returns only the last name of a person by using the comma as a delimiter.
My current expression:
=iif(IsNothing(Fields!EmployeeName.Value), nothing, Left(Fields!EmployeeName.Value,-1 + InStr(Fields!EmployeeName.Value, ",")))
Current results where #Error appears if a name doesn't exist:
The error is occuring because you are passing in a number less than 0 to the left function. When your string does not have a comma in it you are passing in -1.
To handle this I added two if statements to the expression. The first will return the whole string if the index of the first comma is 0. The second checks for the -1 condition and passes a 0 to the left function when that occurs.
=
iif(
IsNothing(Fields!EmployeeName.Value),
nothing,
iif(
InStr(Fields!EmployeeName.Value, ",") = 0,
Fields!EmployeeName.Value,
Left(Fields!EmployeeName.Value,iif(-1 + InStr(Fields!EmployeeName.Value, ",") < 0, 0, -1 + InStr(Fields!EmployeeName.Value, ",")))
)
)
Hi all i have been writing a query and it is driving me crazy because it is giving me syntax error for ''
my query is
UPDATE test1 SET result =
CASE WHEN formula = "p1+p2" THEN 2
the error is here on line 2
any help is highly appreciated.
A case should always have an end:
UPDATE test1
SET result = (CASE WHEN formula = 'p1+p2' THEN 2 END);
This sets result to either "2" or NULL. You probably want:
UPDATE test1
SET result = 2
WHERE formula = 'p1+p2';
As a general rule, use single quotes for string constants. This is the ANSI standard.
I have three tables in a mysql database . Deseasetype(DTID,TypeName) , Symptom(SID, SymptomName, DTID) , Result(RID, SID1, SID2, SID3, result).1st two table, i think is clear enough.
In result table: there will be combination's of symtoms and any values of SymID1/ SymID2/ SymID3 can be null. here i send a picture of the table result.
I want to input some symptom and output will be the result from the 'Result' table.
For that i wrote this query:
$query = "select Result from result where (result .SID1= '$symptom1') AND (result.SID2= '$symptom2' ) AND (result.SID3 = '$symptom3')";
This work only when three symptom's have value. but if any of the symptom's are null, then no result found. May be the query should be more perfect.
**please avoid any syntax error in my writing.
That's because you are comparing NULL to an empty string, and they aren't equal. You could try this instead:
SELECT Result
FROM symptom
WHERE IFNULL(symptom.SID1, '') = '$symptom1'
AND IFNULL(symptom.SID2, '') = '$symptom2'
AND IFNULL(symptom.SID3, '') = '$symptom3'
Notes:
You need to correctly escape the values of $symptom1, $symptom2 and $symptom3.
This won't efficiently use indexes.
As mark pointed out, the query is eventually falling down to compare with null if you are not escaping the null.
Or you can slightly change your logic to show a empty symptom with value '0' and then using the coalesce function you can easily build your query.
Does this work?
$query = "select Result from result
where (result.SID1 = '$symptom1' OR result.SID1 IS NULL) AND
(result.SID2 = '$symptom2' OR result.SID2 IS NULL) AND
(result.SID3 = '$symptom3' OR result.SID3 IS NULL)";
