I want the names of those who rented the vehicles in an easy-to-read table. As you can see, the flattened table has been pivoted and extra rows have been generated for where there are additional drivers.
But firstly. But, as you can see, errors occur where there are additional drivers. We do need to pivotbut we also need to write some code to generate those extra rows. That way, you can click on the individual steps and see how the query transforms the data.
There are also some notes about the query below. Download the Excel file. How to open up Power Query from Excel. When you have a query calling a particular list multiple times it is best to buffer the list in memory by using the List.
Buffer function so it is not computed each and every time. It is worth reading through the MSDN Power Query M function referencepicking out the more interesting functions and playing with them. This definitely paid off; I knew I needed something akin to a jagged array in a table and that Table. FromColumns would give that to me.
The last aspect is non-Power Query related but very important in making the table readable. The black horizontal lines spanning the table that separate the table into their respective days are created in Excel by applying conditional formatting using a formula.
First, select the data in the table or quickly, select one the values in the table and press Ctrl-A. If K5 is the topmost cell in the data of the date column, then apply the formula:. If the table expands upon a refresh then the conditional formatting will not expand correctly. Hi — thanks for this solution. I cannot get the Table name to read, and unfortunately, my company blocks the file download. What do you put in the Table field of the pop up when you invoke the function?
This will then open up Power Query and your table will be there. If you still have issues, reply back with the error message. I tried adding it in a blank query, but then I get the error. Hi Beth, you need to get rid of the quotation marks surrounding Table1 in the function to reference the table. Cheers, Cameron.This article demonstrates how to use the Excel Power Query tool to create pivot tables that organize and display values without calculations count, sum, average, etc.
This can be used if the table contains text data or if you need the real values displayed in the cells. Create a Pivot table that displays text data or number values that are not summarized count, sum, etc It is also much simpler than typing codes and don't require any 3rd party add-on.
You must select only the exact the data range you have. I would ask, if it's possible to have two different types of values in the value area, side by side, perhaps in two columns. Thank you in advance! Alas, I have a new problem. If I have multiple rows for "Daniel" with "created" in other words, he created multiple timesthis creates a problem. I want the value -- not a count -- but Excel won't concatenate the values in the same cell -- it spits out an error that says:.
Error: There were too many elements in the enumeration to complete the operation.
Suggestions for this one? Ideally, what I want is one row for Daniel with all times he created in the same cell with some separator between them. In mine, everything wound up in the right pivoted columns, but I still have 3 rows. The values I used for the pivoted column were text not time -- does this make a difference? How can I consolidate so that I only have one row for each "person" using your example? Aha; I figured it out. I had concatenated two other columns and not removed the originals until after the pivot, thus there was data that didn't fully match.
Once I moved up the removal of those columns, it worked like a charm! Excel - Pivot tables with text values or numbers without calculations. Objectives Create a Pivot table that displays text data or number values that are not summarized count, sum, etc Power Query tool data selection.

Understood on there being thousands of Comids but that wasn't the question. How many allocations can you have per Comid? If the answer is "unknown", then have a look at the following article for how to easily do dynamic cross tabs. For better and faster solutions please check It's easy. If you don't want this, change the order by clause to use the ComId.
Essentially the same solution as Jeff's, but with pivot instead of case and a larger number of returned columns. I believe that individual case statements are more efficient than pivot, I just like the readability of the pivot operator. I have used Dynamic Cross tab to deal with this thing, Now i need help in sending pipe delimited data to a text file.

SQL Server has a PIVOT relational operator to turn the unique values of a specified column from multiple rows into multiple column values in the output cross-tabeffectively rotating a table. It also allows performing aggregations, wherever required, for column values that are expected in the final output.
As you can see in the image below, it has sales information for some countries for a couple of years.Video_021 How to Pivot Column using Don't aggregate function with Power Query?
Also, if you notice, for each country and for each year there is a separate row. Now by using the PIVOT operator, we will convert row values into column values with the script given below and the results as shown in the image below.
Though we have used the SUM aggregation function, in this case there is no summation, as there is only one row for each unique combination for country and year.
Please note the use of brackets for pivot column values; these are required. If you notice in the above script, we have provided values, and for pivot columns as these values are available in the original datasets.
But what if some additional values are expected to come in the future, for example andetc. In that case, you can still use the pivot column values, which are expected to come or which are still not available in the original dataset in the future though you will see NULL for its values.
The script below shows this scenario and the image below shows NULLs for the years and as there is no data for these years. In that case, you can write a dynamic query to first grab all the unique values for the pivot column at runtime and then a write dynamic query to execute it with the pivot query as shown below:.
Let me demonstrate this with an example; lets create a table with pivoted data from the previous query with the script below. The image below shows data of the newly created table with pivoted data.
The image below shows rotated data:. The reason is, Pivot performs aggregation while rotating row values into column values and might merge possible multiple row values into single column value in the output. For example, consider for a given country and year there are two values, say and Now when you pivot it, the output will have as the column value if you have SUM as the aggregation function.
Later if you want to unpivot it back, you will get not the bi-furcated values and as original. Having said that, we can say if the pivoted values are aggregated values, it will not be possible to get the original data back. I also talked about writing a dynamic query to write a dynamic pivot query in which possible pivot column values are determined at runtime.

Learn from thousand of experts, get answers to your questions and share knowledge with peers. I am trying to fetch a data from database where i want to use pivot function.
But i have seen in many examples it is requiring an aggregate functions of SQL. Pivot requires the usage of the aggregation function, but it can be applied to varchar values, it does not have to be only count or sum.
Also, you should include sample data as requested on the FAQ - Re: 2. How do I ask a question on the forums? Sure, you can do it, but it's more complicated and less efficient. Pivoting is a type of aggregation, that is, producing one row of output from many rows of input. Since you want to do aggregation, take advantage of the functions designed for it.
With that said, there are also aggregate functions that only apply to strings. If you apply them to numbers, Big Brother Oracle may not throw an error, but it will convert numbers to strings first, without asking you if that's OK. Unless I have missed something which is entirely possible The point is OP's "test"data is rubbish for showing anything of use for pivoting methods with aggregates as it does not need aggregating.
But if that's the case, then 1 the OP should say so, he shouldn't let us guess based on the posted sample; and 2 the data model would be quite inefficient. More likely, in the real-life problem, this additional assumption is actually false. I used MAX. In any case, my best guess is that the OP has seen examples with SUMand didn't think that would work on strings.

In your OP, you stated that you will have an larger number of rows to turn into columns. If that is the case, then you can use dynamic SQL:.
A workaround might be to ensure that the obligatory aggregation is only ever applied to a single record. In Excel for example the output could be:. Learn more. Pivot rows to columns without aggregate Ask Question. Asked 7 years ago.
