I have a column- amount.
I need to split this into 5 and show it for the next 5 years.
Example:
If the amount is 1000, I need to split it equally into 5 and show it for the following 5 years.
Like 1000/5 and the answer should be
2018-200, 2019-200, 2020-200, 2021-200, 2022-200.
How can this be done in Mysql?

So I currently have a database with about 100.000 measurement results from 850 unique tests on 20 devices at 4 different temperatures.
Now i want to create 4 tables from my database containing 850 rows (1 for each unique test) and 20 columns containing the result of each of the unique devices at a single temperature.
I have attached a picture to visualize this below.
Anyone know what kind of SQL operation i should be using to get this output?
I'm not sure if SSRS is dumb, or I am (I'm leaning towards both).
I have a dataset that (as a result of joins etc) has some columns with the same values duplicated across every row (fairly standard database stuff):
rid cnt bid flg1 flg2
-------------------------------
4 2882 1 17 3
5 2784 1 17 3
6 1293 1 17 3
18 9288 2 4 9
20 762 2 4 9
Reporting based on cnt is straightforward enough. I can also make a tablix that shows the following:
bid flg1 flg2
------------------
1 17 3
2 4 9
(Where the tablix is grouped by Fields!bid.Value and the columns are just Fields!flg1.Value and Fields!flg2.Value respectively.)
What I can't figure out is how to display the sum of these values -- specifically I want to show that the sum of flg1 is 21 and the sum of flg2 is 12 -- not the sum of every row in the dataset (counting each value more than once).
(Note that I'm not looking for a sum of distinct values, as they may not be unique. I want a sum of one value from each bid group, because it's from a table join so they will always have the same value.)
If possible, I'd also like to be able to do a similar calculation at the top level of the report (not in any tablix); although I'd settle for hiding the detail row if that's the only way.
Obviously, Sum(Fields!flg1.Value) isn't the answer, as this either returns 51 (if on the first row inside the group) or 59 (if outside it).
I also tried Sum(Fields!flg1.Value, "bid") but this wasn't considered a valid scope.
I also tried Sum(First(Fields!flg1.Value, "bid")) but apparently you're not allowed to sum first values for some weird reason (and may have had the same scope problem anyway).
Using Sum(Max(Fields!flg1.Value, "bid")) does work, but feels wrong. Is there a better way to do this?
(Related: is there a good way to save the result of that calculation so that I can later also show a Sum of those totals without an even hairier expression?)
There are two basic ways to do this.
Do what you have already done (Sum(Max(Fields!flg1.Value, "bid")))
Sum the rendered values. To do this check the name of the cell containing the data you want (check it's properties) and then use something like =SUM(ReportItems!flg1.Value) where flg1 is the name of the textbox, which is not necessarily always the same name as the field.
I'm using Microsoft Access 2007 to query two separate SharePoint sources.
The first has most of the data I need. The unique ID number for each row in the first has a corresponding column in the second. The ID from the first can occur multiple times in the second. (It's a mapping between two different databases of defects.)first.
What I want to do is this: find all the ID's from table one that occur in the second, and list ID's from the second for each item that corresponds with the first. For starters, I want something a bit like this:
Table 1 ID Table 2 ID's
5 9, 13, 23
10 11, 15
20 8
But there's also more data from Table 1 I want to display for each item.
What I'm getting is this:
Table 1 ID Table 2 ID Table 1 Data
5 9 Row 5 Additional Data
5 13 Row 5 Additional Data
5 23 Row 5 Additional Data
10 11 Row 10 Additional Data
10 15 Row 10 Additional Data
20 8 Row 20 Additional Data
What I want is something like this:
Table 1 ID Table 2 ID's Table 1 Data
5 9, 13, 23 Row 5 Additional Data
10 11, 15 Row 10 Additional Data
20 8 Row 20 Additional Data
Or perhaps:
Table 1 ID Table 2 ID's
5 9, 13, 23
Row 5 Additional Data
10 11, 15
Row 10 Additional Data
20 8
Row 20 Additional Data
How can I create a report like that?
Comma-separated list from multiple records
Grouping of multiple data rows into a comma-separated list is not a built-in feature of Access. There are various ways to do this, but I most often see links to Allen Browne's tutorial.
Multi-line row details
The difference between your last two examples is just a matter of formatting a Form or Report in Design View. A Report (here capitalized) in Access is a specific type of object for generating custom, formatted views of your data, often for printing or read-only viewing. A Form is a dynamic, on-screen view of your data. I suspect that your use of "report" is of a more general sense.
First of all, there is no way to make multiple lines using the default Datasheet View of tables and queries. To get multiple lines per row of data, you need to create a Form or Report object in Access. In Design View, you can move the data controls around the detail area to produce multiple lines for each data row. I suggest searching for tutorials on the web for creating Access Forms and Reports.
See Guide to designing reports.
ok, i'm not sure if i can explain this right.
Lets say i have a table with three columns (id, price, maxcombo)
maybe there's like 5 rows in this table with random numbers for price. 2. id is just incremental unique key)
maxcombo specified if that price can be in a combination of up to whatever number it is.
If x was 3, i would need to find the combination that has the maximum value of the sum 1-3 columns.
So say the table had:
1 - 100 - 1
2 - 50 - 3
3 - 10 - 3
4 - 15 - 3
5 - 20 - 2
the correct answer with be just row id 1.
since 100 alone (and can only be alone based on the maxcombo number)
is greater than say 50 + 20 + 15 or 20 + 15 or 10 + 20 etc.
Does that make sense?
I mean i could just calculate all the diff combinations and see which has the largest value, but i would imagine that would take a very long time if the table was larger than 5 rows.
Was wondering any math genius or super dev out there had some advice or creative way to figure this out in a more efficient manner.
Thanks ahead of time!
I built this solution to achieve the desired query. However, it hasn't been tested in terms of efficiency.
Following the example of colums 1-3:
SELECT max(a+b+c) FROM sample_table WHERE a < 3;
EDIT:
Looking at:
The correct answer will be just row id 1
...I considered maybe I misunderstood your question, and you want the query just obtain the rowid. So, I made this other one:
SELECT a FROM sum_combo WHERE a+b+c=(
SELECT max(a+b+c) FROM sum_combo WHERE a > 3
);
Which would for sure take too long in larger tables than just 5 rows.
I would like help with sql query code to push the consequent data in a specific column down by a row.
For example in a random table like the following,
x column y column
6 6
9 4
89 30
34 15
the results should be "pushed" down a row, meaning
x column y column
6 null or 0 (preferably)
9 6
89 4
34 30
SQL tables have no inherent concept of ordering. Hence, the concept of "next row" does not make sense.
Your example has no column that specifies the order for the rows. There is no definition of next. So, what you want to do cannot be done.
I am not aware of a simple way to do this with the way you are showing the table being formatted. If your perhaps added two consecutively numbered integer fields that provide row number and row number + 1 values, you could join the table to itself and get that information.
After taking a backup of you table:
Make a PHP function that will:
- Load all values of Y into an array
- Set Y = 0 (MYSQL UPDATE)
- load the values back from PHP array to MYSQL
