How to Remove Repeated Column Values from Report

How do I remove repeated column values from report

Is this the structure of the table that you are showing (or) is it the result of a report?

My guess is it is the result of a SQLPLUS report. If that is the case, and you want the Hotel name to appear once (until it changes), you can specify

Break on hotel;

Select hotel, type, room_guest
  from hotels
  order by hotel;

to achieve the desired result.

If it the structure, you cannot delete the column values for all but the first row. (in fact, there is nothing like the first row as far as the database is concerned). If you are trying to eliminate duplicate data, then look into normalizing your table.

Please post the table description and the tool (if any) so that you'd get the appropriate answers for your case.

Blank out duplicate column values in SQL Reporting Services

It is probably best to simply use groups, but if you want to keep it this way, try:

=IIf(Previous(Fields!Col1.Value) = Fields!Col1.Value, Nothing, Fields!Col1.Value)

Or you can set the textbox's HideDuplicates property to the containing group name (in your case, presumably Tablix1_Details)

SSRS remove duplicate row entries

Here you cna try by adding Row group on your tablix.

You need to add first Row group on Name and second row group on Account so it will be look like

Name|Account|Note
John|123456 |note1
    |       |note2
    |       |note3
John|654321 |note1
    |       |note2
    |       |note3

search for row group you will get result.

How can I remove duplicate rows?

Assuming no nulls, you GROUP BY the unique columns, and SELECT the MIN (or MAX) RowId as the row to keep. Then, just delete everything that didn't have a row id:

DELETE FROM MyTable
LEFT OUTER JOIN (
   SELECT MIN(RowId) as RowId, Col1, Col2, Col3 
   FROM MyTable 
   GROUP BY Col1, Col2, Col3
) as KeepRows ON
   MyTable.RowId = KeepRows.RowId
WHERE
   KeepRows.RowId IS NULL

In case you have a GUID instead of an integer, you can replace

MIN(RowId)

with

CONVERT(uniqueidentifier, MIN(CONVERT(char(36), MyGuidColumn)))

rdlc Report in VS2015 - Repeating values being suppressed

Two possibilities:

1. Text box was explicitly set to suppress duplicating values. To change it - click on text box (table cell) and press F4. Then, change "HideDuplicates" property to False.

2. These columns were added in the process of adding groups to the table. So, they are "group headers" of a sort. To remove suppressing of the duplicates in this case, delete those columns. Note: be sure to change the following to "Delete Columns Only":

   

   And then re-add two columns to the left of your first column and set their values to appropriate fields values.

How to remove duplicates in power BI grouping by a particular column?

In power query, you can use the "group by" feature, with some modification, to accomplish this. Here is the step you will need to add to do this:

= Table.Group(#"Previous Step", {"timestamp", "id"}, {{"revision", each List.Max([revision]), type nullable number}, {"value", each Table.Max(_, "revision")[value]}})

This is essentially telling power query to take the highest revision for each timestamp and id combination, and to also return the corresponding value.

Here is a detailed blog post of how this code works: https://www.ehansalytics.com/blog/2020/7/16/return-row-based-on-max-value-from-one-column-when-grouping

After sorting, here are the results:

Hide duplicate row SSRS 2008 R2

You probably should try these options first:

• Try to clean the duplicate data at the source.
• Change your source query so the duplicates don't appear in the dataset. (e.g. SELECT DISTINCT)

If not, on the row's Visibility Hidden property you can use the Previous function:

=iif(Fields!YourField.Value = Previous(Fields!YourField.Value), True, False)

You would have to sort on the YourField column for it to work.

How do I remove duplicate rows from a view?

DISTINCT won't help you if the rows have any columns that are different. Obviously, one of the tables you are joining to has multiple rows for a single row in another table. To get one row back, you have to eliminate the other multiple rows in the table you are joining to.

The easiest way to do this is to enhance your where clause or JOIN restriction to only join to the single record you would like. Usually this requires determining a rule which will always select the 'correct' entry from the other table.

Let us assume you have a simple problem such as this:

Person:  Jane
Pets: Cat, Dog

If you create a simple join here, you would receive two records for Jane:

Jane|Cat
Jane|Dog

This is completely correct if the point of your view is to list all of the combinations of people and pets. However, if your view was instead supposed to list people with pets, or list people and display one of their pets, you hit the problem you have now. For this, you need a rule.

SELECT Person.Name, Pets.Name
FROM Person
  LEFT JOIN Pets pets1 ON pets1.PersonID = Person.ID
WHERE 0 = (SELECT COUNT(pets2.ID) 
             FROM Pets pets2
             WHERE pets2.PersonID = pets1.PersonID
                AND pets2.ID < pets1.ID);

What this does is apply a rule to restrict the Pets record in the join to to the Pet with the lowest ID (first in the Pets table). The WHERE clause essentially says "where there are no pets belonging to the same person with a lower ID value).

This would yield a one record result:

Jane|Cat

The rule you'll need to apply to your view will depend on the data in the columns you have, and which of the 'multiple' records should be displayed in the column. However, that will wind up hiding some data, which may not be what you want. For example, the above rule hides the fact that Jane has a Dog. It makes it appear as if Jane only has a Cat, when this is not correct.

You may need to rethink the contents of your view, and what you are trying to accomplish with your view, if you are starting to filter out valid data.
