I have an RDLC report with a table in it. I want to hide a string column if there is no data present in any of the rows(supress if blank sort of thing). I have been googling for the last 2 hrs and trying with different suggestions but i can not make it work.
I tried the following so far.
Set the expression for the Hidden attribute of the column to
=IIf(Fields!Category.Value = "", True, False)
But it is checking only the first row but not the entire row set.
Trying to create a concatenated string with the field values, so if the final string is empty i'll hide the table column. But i can't find a way of concatenating a string column from a table. Runningtotal() works with only numbers it seems.
Can some one point me to the right direction.
initially i thought it is very easy, but doesn't seem so.
Did you try to use CountDistinct?
I think something like this should do the trick
=(CountDistinct(Fields!Category.Value) > 1) Or (Fields!Category.Value != "")
Or you can try to make a custom string aggregate function

This is the data set I am trying to filter in Report Builder.
All columns have numerical values(blacked out) except for the first 'name' column.
I want to filter this table based on the row's string value from this 'name' column.
Complete table
I have tried to hard-code the 'name' values into the filter within the Tablix properties. I have tried various configurations to get the result of a single row based on the 'name' value (in this example, the first row).
Report Builder Tablix Properties
Every attempt results with an empty table. I am not sure what I am doing wrong, and the advice of other posts have not provided a solution that works for me.
Empty table :(
Any advice would be greatly appreciated!
Make sure your columns are not aliased with SQL Keywords.
In this example, name is a SQL keyword. I changed it to [CALCULATION] and the filter worked with the following expression in the tablix properties;
Corrected Tablix Properties
Note that the filter works with both having the string value with no quotes nor equal sign in front of the expression, and also works with an equal sign and quotes around the string value.
I have a store procedure which brings the data as shown below . I'm new to SSRS reporting, I would like to show only those row where "email" column is null. How can i achieve it in SSRS ? As i mentioned I'm very new to this , any screenshot will help me a lot. Thank you for your time.
For this problem, you'll want to change the row visibility to hide rows with a value in that column. I assume you're using a table or matrix to layout this data. You'll want to right click on the row where your data fields are entered. Specifically, the grey box at the left of the row.
From there, you'll need to select the option to Show or hide based on an expression.
And finally, you'll need to enter an expression that finds the values in the email field. I'm not exactly sure what the field names are called but something like the following expression should do it.
= Not IsNothing(Fields!EmailField.Value)
This will check the field where you get the email value with a built-in function of IsNothing. Additionally, since you want fields that do not contain values, the Not keyword reverses the results. If the function evaluates to true and a value is present, the row will be hidden and vice versa.
I'm using the "phpsoda" library and trying to query the city of Seattle's permits dataset through the Socrata API (SODA). Data: https://data.seattle.gov/Permitting/Land-Use-Permits/ht3q-kdvx
They have several columns such as the ones I'm selecting below, but in the "AppliedDate" and "IssuedDatae" columns, there may or may not be data in that column.
So when I try to look at the array and arrange this into an HTML table, I'm getting some arrays (rows) that have fewer elements (columns) than other rows. This turns out to make it difficult to display since I don't know which columns are missing in the array (row).
I'm wondering if when I make the query, that those empty fields will look they seem in the visualized table on their site or when I export a CSV. Those columns in the query will return into the array element an empty string ("") instead so my rows and columns will come out all filled with values.
$soql->select("PermitNum", "AppliedDate", "IssuedDate", "Description", "OriginalAddress1")
->where("PermitClass = 'Multifamily' OR PermitClass = 'Commercial')
->limit(20);
$results = $ds->getDataset($soql);
Data would look something like...
print_r($results);
Array[0] -> [Description]=>"XXXXXXX", [PermitNum]=>"123456"
Array[1] -> [Description]=>"XXXXXXX", [PermitNum]=>"234567", [AppliedDate]=>"XX/XX/XXXX"
So the first row is missing the "AppliedDate" column just because it's not in the data.
Will I need to just go through this manually in the results array using a loop and checking column names and inserting an empty string if the loop doesn't find a column?
Following my own advice, I was able to just check for each row key if a specific key was missing (array_key_exists function), then I'd fill it in with "" if it returned false.
This seemed to work.
I have same problem. Socrata API will skip empty field or null value. Means, if field is null or empty, the result will not show field-name:'', instead, the result will just missing this, that cause your shorter row.
This is annoying bug, I have to fix it by my own. If I found it missing field, I will have to add field-name:'' to the result json, that will fix your shorter row problem. Make equal length row.
I have a text file with more than one table's data in it (different column counts). I import the whole row as one column. Based on a conditional split, the rows are dispersed to their correct flow. I use a script component to split the single column values (row) into the correct columns for that table and give it as output columns. All of this is working fine, and data looks fine.
My problem comes in with some numeric fields. When a numeric field has no values in it, it ends up in the table with another column's numeric value.
I have put data viewers everywhere, in not one of them there is data for the column that should be empty. When I look in the table itself, there it is... data from another column.
It is not the mappings, I checked it a dozen times.
It is not the names that are the same or something like that.
There is no data according to dataviewers anywhere in the load process.
There is no hidden code anywhere.
I droped and recreated the table.
I displayed a messagebox with the column's (that is supposed to be empty) assigned "column value", and no data, like expected.
I used a derived column, same result, no data in dataviewers, but eventualy data in the table.
I also created another test table with those numeric fields as varchar. When I do this, the column is empty (like expected). When I change it to numeric, the field is populated again. (If it was the other way around I could understand).
What can be te reason for this? It is driving me insane.
EDIT
Script code:
//C#
public override void Input0_ProcessInputRow(Input0Buffer Row)
{
ASCIIEncoding enc = new System.Text.ASCIIEncoding();
char[] seperator = { '|' };
Byte[] ByteBlob;
String[] ColumnValue;
ByteBlob = Row.Column0.GetBlobData(0, (int)(Row.Column0.Length));
ColumnValue = enc.GetString(ByteBlob).Split(seperator);
Row.OutputColumn0 = ColumnValue[0];
Row.OutputColumn1 = ColumnValue[1];
///etc
Just to give an example of what it does, this is what a row would look like in a sence.
Column names:
Source|Tablename|Value1|Value2|Description|Value3|Description2|Value4
Actual Data:
ABC|Revenue|123,456|729,537|MisterX||None|
Data in Table:
ABC|Revenue|123,456|729,537|MisterX|729,537|None|729,537
try using Row.ColumnX_IsNull , for example if (Row.Column0_IsNull) {youroutputcolumn=null} else {...}
Hi All I need your advice,
1) I have a dynamic string which changes each time.
for example today the string will be "ItemA,ItemB,ItemC" and tomorrow it will be "itemA,ItemB" only.
2) I have an SSRS report which has 3 columns
3) I want to split this string "ItemA,ItemB,ItemC" and want to show split substrings in these 3 columns of ssrs table. the Delimiter is "," (comma)
4) I had used
=Split("ItemA,ItemB,ItemC",",").GetValue(0) in the first column of the report
=Split("ItemA,ItemB,ItemC",",").GetValue(1) in the second column of the report
=Split("ItemA,ItemB,ItemC",",").GetValue(2) in the third column of the report
5) everything works fine until my string is "ItemA,ItemB,ItemC" ,
BUT WHEN MY STRING CHANGES TO "ItemA,ItemB" I am seeing "#Error" in the third column.
I understood the error, for
=Split("ItemA,ItemB,ItemC",",").GetValue(2) we don't have any value because the string now has only 2 values after applying split function.
Is there any way i can avoid #Error in the third column.
NOTE: I have to compulsorily use 3 columns in the ssrs report.
I had tried using =Replace(Split("ItemA,ItemB",",").GetValue(2),"#Error","NULL") in the third column but that also wont worked.
This is similar to the divide by zero issue in using IIF statements. The problem is that IIF is not an expression, it is a function with three parameters:
IIF(Condition, ValueIfTrue, ValueIfFalse)
Accordingly, ALL parameters are evaluated BEFORE being passed to the function, which results in the error because the erroneous expression is still evaluated even when the condition should mean that it isn't.
I can't see a way to use the usual workaround tha solves the problem in the divide by zero case. What we need is a real language that doesn't have this problem. Fortunately, this is availble in the form of custom code.
Do the following:
Right-click on an area of the report surface that has no report objects
Select Report Properties
Click on the Code tab
Insert the following code:
Public Function ExtractCode(Combined As String, Position As Integer) As String
if (Split(Combined, ",").Length >= Position) Then
Return Split(Combined, ",").GetValue(Position-1)
Else
Return ""
End If
End Function
Click OK and go back to the report
Right-click on the cell you want the expression in and click Expression
Insert the following expression:
=Code.ExtractCode(Fields!Combo.Value, 3)
The value 3 is the "column" that you want to extract from the Combo field, so to get the second "column" you would use 2. If there isn't a column at that position, an empty string is returned.
you could change the visibility of the 3rd column to hidden if the name returns an error
You can append a dummy element and then split:
yourText = "ItemA,ItemB"
item0 = Split(yourText & ",", ",").GetValue(0)
item1 = Split(yourText & ",", ",").GetValue(1)
item2 = Split(yourText & ",", ",").GetValue(2)
item0 = ItemA
item1 = ItemB
item2 =
