Is there any way to sum a column in rdlc by matching previous column? Let say I have a Code_No column and the Value of this column may be duplicate. I want to sum its left column only if the value of this Code_No column are different.

The Yield values need to be created in the Measure column which is based on the same column values.
That is the Value of (Saleable MetIN+Saleable Thermal)/FeedIN.
I tried using CTE but the query is getting too big.
Columns Names:
YEAR,
ANO_MONTH,
ANO_WEEK,
MONTH_CODE,
WEEK_CODE,
EQMTID,
MEASURE,
VALUE
I have this data:
It's ordered ascendingly by the left hand column. I'd like a query that says if the timestamp in the right-hand column is before the timestamp of the preceding row, to return that row.
TIA
I am trying to create a dynamic column in a table whose column name will be today's date and values will be populated based on a mathematical operation of an existing column. For example table, t1 has column a,b,c and I want to add a column called '04-26-2021' whose value will be a+b+c values. Does anyone know how we can implement it in Postgresql? Thanks
I have a column group nested in row groups. I want for the column group to only show a row for each item in the row group.
Is there any way to do this?
I resolved this by adding a row group inside the column group. I grouped the Results column using row group and it worked!
I have a database table that has multiple codes in one column that correspond to certain values in another column. For example, a particular code in column A corresponds to a value in column B. There are thousands of duplicate entries in column A that correspond to different values in column B. I want to add up all of the values in column B that have the particular code in column A, while only keeping one copy of the code from column A. You may think of the columns as key-value pairs, where column A contains the key and column B contains the value.
Basically, I want to add all the values in column B where column A is a specific value, and I want to do for this all of the unique "keys" in column A. I'm sure that this is a simple task; however, I am pretty new to SQL. Any help would be greatly appreciated.
Here is the result I'm looking for.
This should work:
SELECT
A,
SUM(B) AS sum_b
FROM [yourTable]
GROUP BY A
SELECT COLUMNA, SUM(ISNULL(COLUMNB,0)) AS TOTAL
FROM
dbo.TableName
GROUP BY COLUMNA
