I Have a very simple question regarding SSRS, I also tryied many ways but not getting correct value
:
Example:Say i have report and i have to add first three column into last column as
column1 Column2 Column3 Total
2 4 6 12
1 2 3 6
I tried to add this logic in my expression code as :
=Sum(Fields!Column1.Value, "DataSet1")+Sum(Fields!Column2.Value, "DataSet1")+Sum (Fields!Column3.Value, "DataSet1")
But this is not working and returning #ERROR in last column , can you please suggest the correct way to add the column values into one column.
Try Removing SUM() function because this is an aggregate function
Fields!Column1.Value + Fields!Column2.Value + Fields!Column3.Value
or just change your sql query to something like
select Column1, Column2, Column3, Column1 + Column2 + Column3 Total
from [your Table]
[where id = ???]
Can you use the combination of the textboxes instead of the sum of the fields?
ReportItems!textbox1.value+ReportItems!textbox2.value+ReportItems!textbox3.value

I have tried to select something with SQL, and I've a problem with it.
What I want:
SQL SELECT * FROM table WHERE ? = '5';
Select everything which = 5, BUT not specify from which column.
Example:
From this ""database"", you should receive the 1st and the last row.
Is that possible?
You have to list the columns but you can use in. The where clause looks like:
where 5 in (price, height)
Note: This assumes that the columns have the same type. You could get type conversion errors if they are not.
Also, given the names of the column and the data, I assume that the columns are stored as numbers. Hence, I dropped the single quotes around 5. If they are really strings, then use the single quotes.
you need to add a condition to your query with or keyword so if any of them match the row will be shown as a result
SELECT * FROM tablename WHERE price =5 or height= 5
better you list your columns by name instead of using * after SELECT
I have a MySQL table with 8 fields/columns. Of these, 5 columns have either 0 or 1 as values. I would like to show only those fields whose value is 1 for a particular ro .
The obvious method is to run a query like this:
SELECT * FROM table WHERE field1=1 OR field2=1 OR field3=1 OR field4=1 OR field5=1 ;
This will yield a resultset containing 8 fields/columns where the conditions are satisfied.
But what I want to try is to run a query which gives a result-set containing only that fields which has 1 as value.
Is it possible?
If possible, how can I do this?
Unfortunately, I don't think this is possible.
If you think about it when reading the resultset you'll have
to for example do :
$row[0]
Which will vary from row to row with what you're trying to do.
The result of $row[0] will always be 1 but the column selected
will differ from row to row, which is pretty confusing IMO.
A solution would be to change the design of the table and set:
visibleField1, visibleField2, visibleField3, visibleField4, visibleField5
and fill the column with the name of the field you want to show.
or name the field visibleFields and fill it with "field1,field2,field5" when you want to show those three
There's probably other ways to do this design change.
You could try it like this:
SELECT id,
CASE
WHEN field1 = 1 THEN 'badge_name'
WHEN field2 = 1 THEN 'other_badge_name'
...
END AS badge
FROM your_table
You can see an example at the link below that uses a couple stack overflow badges:

I am trying to run a query directly in MySQL to run through a series of records and replace the value of field with just the field character of the row.
e.g based on a column called formname
row 1 - Renault
row 2 - Citreon
row 3 - Jaguar
That will return..
row 1 - R
row 2 - C
row 3 - J
I can do this easily using native PHP functions but unsure how to do this using a native MYSQL function SUBSTR function?
You can use left
update table
set column = left(column,1)
or for select you can write
select col1,left(col2,1)
from table
Demo
To get this with the SUBSTR() function like you are asking for, you would use:
SELECT Field1, SUBSTR(field2, 1, 1)
FROM MyTable
The function definition: SUBSTR(str,pos,len)
Hello I have a table with 4 column in the column 4 the value come from a list box already pre establish by me , let say column 4 is populate by value a,b,c,d,e,f,g,h,i,j.
presently I can sort them in alpha order and get that on a PHP page .
I will like to be able to get on a page just d,e and f
how can I achieve that
thank you all
SELECT * FROM mytable WHERE mycolumn4 IN ('d','e','f')
You can just do:
SELECT column4
FROM TABLE
WHERE column4 IN ('d','e','f')
ORDER BY column4 ASC;
or if you know you want the elents with letters "bigger" than 'd' but don't know how many they are, you can do:
SELECT column4
FROM TABLE
WHERE column4 >= 'd'
ORDER BY column4 ASC;
I'm having trouble with sorting out a query for the following:
Data:
Column1 Column2
2 0
0 -2
I'm trying to select the difference between Column1 and Column2, with a minimum of 0. Eg.
Row1=2
Row2=0
My current query is SELECT (Column1 - Column2) as total FROM blah.
I tried adding max(Column2, 0) into the query, but that just errors.
Try:
SELECT GREATEST(Column1 - Column2, 0)
from Table
The MySQL function MAX() is an aggregate function, often used in combination with a GROUP BY. It only takes one argument (the name of the column of which you want to select the maximum value). The GREATEST() function is the function you need (as Michael Pakhantsov pointed out).
