I have a requirement to display row values as column names in a data grid view. I want to get the store names into columns using sql select statement. (Please refer the attached image). I want user to enter some values under each column. So STORE 1, STORE 2, STORE 3 should displays as columns in datagrid view. Does anyone can help me to get this work?
while googling i found this can be done using PIVOT in SQL. But in this table i don't have any aggregate columns. Any help pls?
the result should be somthing like
You may know that your data only contains a single row for each pivoting column, but SQL Server has to construct a plan that could accommodate multiple rows.
So, use PIVOT and just use an aggregate that, if passed a single value, will return that same value. MIN() and MAX() fit that description (as does SUM if you're working with numeric data)
You may use specific function of dynamic pivot and pass your query with item count column.
You can use below link which provided you function and can easily show you expected output.

The table retrieves data from the table "Group" with 2 columns First key "GroupNumber" and GroupName"I am trying to create a sql query in Microsoft Access from a table with two columns that will works as below:
Based on the user's selection from the first column the query has to return the value of the second column, and based on the user's selection from the second column the query has to return the value of the first.
Any idea how is possible to express the user's selection in sql? Ty
Some more data would be useful. AT this moment, it is hard to understand what it is exactly you are trying to do.
However, you mention two different selecting actions that need to be done by the user, so two SELECT statements would work.
To return the value of the second column based on user selection of the first: SELECT second_column_value FROM table WHERE first_column_value = value_selected_by_user
To return the value of the first column based on user selection of the second:SELECT first_column_value FROM table WHERE second_column_value = value_selected_by_user
or you can use drop-down lists, if the situation allows
Try providing more data to get more useful answers.
I have a column of type string in my table, where multiple values are separated by pipe operator. For example, like this,
Value1|Value2|Value3
Now, what I want is to have a query, which will show three rows for this row. Basically something similar to the concept of explode in Dataframes.
Note that I am using Spark SQL. And I want to achieve this using SQL, not dataframes.
I got it working by using the following query.
select t.*, explode(split(values, "\\|")) as value
from table t
\\| here can also be replaced by [|]. Just specifying | doesn't work.

I am trying to create an SSRS report which will run select * on a table passed in as a parameter and display all the data from that table. As I understand it, I can't use a table for this. I want to use a pivot table to achieve this.
select * from #table will return something like this (from the adventureworks DB)
I want to display the date in this format:
Question
How do I achieve this? I looked at using PIVOT/UNPIVOT, but all the examples I've seen use static column names and aggregates.
I won't know the column names at design time (or run time), I'm assuming I will need column headers like 'table name', 'value1', 'value2' etc?
Limitations
I won't have access to create stored procedures. Ideally, the report should be able to be run entirely from SSRS without having to create new tables etc.
Performance is not a concern.
Edit
Editing to add some clarity. The column names in the example above are only an example. The #table parameter could be any table, column names won't be know at design time. The column names could be col1, col2, or name, address... etc.
You can do this with a normal tablix, with a column group on BusinessEntityID
Create a normal tablix.
Remove the row group (group only)
Insert a new parent column group, grouped by BusinessEntityID
Delete the top row (row only)
Add each of the row titles in, as per your suggested output
Add each of the values in the second column
I am using PyODBC to fetch some data, since I am not fetching all data in my table, I need to write a query which grabs only rows which have associated columns. For example my initial query is:
SELECT SRNumber FROM SO_SC_1 WHERE SRNumber LIKE '%1-%'
This returns the SRNumber values that I want.
Next I want to return the associated last edited user with this SRNumber. This column is named last_edited_user. What is the proper syntax to incorporate multiple queries into one for this scenario? Basically I would like to use the initial query and grab all associated data for each SRNumber.
You query all needed columns using their comma separated names
SELECT SRNumber, last_edited_user
FROM SO_SC_1
WHERE SRNumber LIKE '%1-%'
Problem
We are currently working with some data which is stored as in the screenshot below. We are using this to display information in a C# application. The only way we can get the application to work as needed is to have the information in one single row.
We have tried some methods on Display multiple rows and column values into a single row, multiple column values to no avail.
Desired output
We require each row with the same date and vehicleID to be on the same row to be output from our stored procedure.
Any help would be greatly appreciated. Cheers.
if I understood correctly, you don't know how many unique date/vehicle_id combinations there are in the data. hence you can't just do a pivot over a set list of values.
in this case, you would need to build up a list of the date/vehicle ids dynamically, and then pivot over that list.
