I am currently using SQL Server 2008R2.
I am using this script:
SELECT a.productname, a.orderdate, a.workarea
FROM database1table1 AS a
WHERE a.orderdate >='2016/08/01'
Which gives the output:
PRODUCT NAME ORDER DATE WORKAREA
x 2016/08/07 NULL
y 2016/08/09 HOLDING
z 2016/08/10 ACTION
a 2016/08/12 ACTION
My problem arises when I amend the above script to read,
...
WHERE a.orderdate >='2016/08/01'
**AND a.workarea NOT IN ('HOLDING')**
When I do this, not only does it remove 'HOLDING', but it also removes the NULL rows as well, which I definitely do not want.
Please can you suggest an amendment to the script to prevent the NULLS being removed - I only want to see the value 'HOLDING' taken out.
With many thanks!
You can try a workaround
AND ISNULL(a.workarea,'') NOT IN ('HOLDING')
It will transform all null a.workarea in the "where" the "not in" works correctly

I need to be able to use variables in table names - I basically have the same set of tables used for different types of data, so I would like to just have one dashboard and swapping between all types instead of always having to set up multiple identical dashboards.
My query is something like:
select * from table_$variable_name;
Where my list of possible variable is something like cat, dog, bird
I can seem to make this work, if I only put the variable as shown above I get the following error
Error 1146: Table 'table_$variable_name' doesn't exist
If I enclose it in curly brackets, I get this error instead.
Error 1064: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '{bird}' at line 1
(i.e. with the selected variable actually being visible this time)
I'm not sure if the issue is having underscores in the table names, I tried putting underscores around my variables too to check and I had no luck with that.
Another thing I tried was gradually adding on to the table name, so e.g.
select * from table_$variable;
Still returns an error, but I can see the table name starting to form correctly
Error 1146: Table 'table_bird_' doesn't exist
However, as soon as I add another underscore, the variable is not picked up abymore
```Error 1146: Table 'table_$variable_' doesn't exist``
I'm sure it's something silly I am missing in the syntax of the query - anyone has any suggestions?
Using this https://grafana.com/docs/grafana/latest/variables/templates-and-variables/ for reference
As #arturomp suggests, use
${var:raw}
At least in my case, this was the solution that worked.
I found double square brackets work. e.g.
Rather than
select * from table_$variable_name;
use
select * from table_[[variable_name]];
I am trying to get the price items for performance block storage that are generic (not specific to a certain datacenter). I can see that these have the locationGroupId set to blank or null, but I can't seem to get the objectFilter to work with that, the query returns nothing. If I omit the locationGroupId filter I get a result that contain both location-specific and non-location specific prices.
GET /rest/v3.1/SoftLayer_Product_Package/759/getItemPrices.json?objectMask=mask[locationGroupId,id,categories,item]&objectFilter={"itemPrices":{"categories":{"categoryCode":{"operation":"performance_storage_space"}},"item":{"keyName":{"operation":"$=GBs"}},"locationGroupId":{"operation":"is null"}}}
I am guessing there is something wrong with the object filter, any ideas?
If I filter on locationGroupId 509 it works:
/rest/v3.1/SoftLayer_Product_Package/759/getItemPrices.json?objectMask=mask[locationGroupId,id,categories,item]&objectFilter={"itemPrices":{"categories":{"categoryCode":{"operation":"performance_storage_space"}},"item":{"keyName":{"operation":"$=GBs"}},"locationGroupId":{"operation":509}}}
The reason it the first query didn't work while the second did was that I used the command "curl -sg" to do the request. While that eliminates the need to escape the {}[] characters - it also turns off escaping other characters correctly in the URL - like the space in "is null". Changing that to "is%20null" solves the issue.
I am posting this as the answer as I find it likely for others to encounter this problem.
How do I run a query using a value from a textbox from a form I have? I know that there is another post here at Stackoverflow dealing with this issue but I found it to be insufficient for my needs.
I formated my textbox into Medium Date format with its default value being =Date(). However, when I pick up a date and open my report I get this error:
Runtime error 3071: Expression Too Complex
My where clause is this
WHERE
(
(AllInfo.DateOpened >= CDate([Forms]![Main Form]![WindowPrintOptions]![CustomizedReport]!txtDateOpenedFrom.Value))
)
and I am sure it is this code piece that is throwing the problem since when I take it out of the query the error message simply disappears.
Any ideas?
Try with:
(AllInfo.DateOpened >= DateValue([Forms]![Main Form]![WindowPrintOptions].[Form]!txtDateOpenedFrom))
)
Folks,
I got the problem. It was the "AllInfo" alias. It wasn't applicable at that escope inside the query. By changing the proper things, it was enough to write:
[Forms]![Main Form]![WindowPrintOptions]![CustomizedReport]!txtDateOpenedFrom.Value
Issue solved. Thank you all!
I Have created a stored procedure:
#DeviceID nvarchar(20) =''
WITH EXECUTE AS CALLER
AS
SELECT
amd.BRANDID,
amd.DEVICEID
FROM AMDEVICETABLE amd
where
left(amd.Deviceid,len(#DeviceID)) in (#DeviceID)
The length of amd.Deviceid is about 15 characters
In Visual Studio I create a parameter #DeviceID and when I am entering e.g ABCDE ( the first 5 characters from Deviceid) everything is working perfect.
the problem is that I want to put multiple values like
jhmcl*, jhmgd*.
So I created my own little version of your report and I believe the problem is your LEN() function. I'm surprised it doesn't return an error because it errors out in Report Builder for SQL Server 2014(simple version of SSRS). I would test what your LEN(#DeviceID) is returning. I would bet it's not returning the correct value. Instead you might try this to cover every possible pattern. I don't know how it will work performance wise.
SELECT DeviceID
FROM YourTable
WHERE LEN(DeviceID,1) IN (#DeviceID)
OR LEN(DeviceID,2) IN (#DeviceID)
OR LEN(DeviceID,3) IN (#DeviceID)
..
OR LEN(DeviceID,15),IN(#DeviceID)
I'm trying to import a .csv file into phpmyadmin where several fields are purposefully left blank. I need these field to register as null values and not just left as a blank string.
I know in the field properties you can select to allow "null" vs. "not null" for each field, but it still doesn't change cell to a null value while importing. After the import I can manually go check the null box for each field on each record, but that it unrealistic considering the amount of data I'm working with.
Is there a way to get phpmyadmin to set these blank cell to null values on import?
I've been experience similar issues.
If you download a PhpMyAdmin CSV file with NULL values, you'll notice that NULL doesn't get encapsulated with quotes. So you'll have a line like this:
"1";"2";NULL;NULL
"2";"2";NULL;NULL
etc.
However, if you edit a CSV file in something like Open Office Calc, it might change this to put quotes around NULL, like so:
"1";"2";"NULL";"NULL"
"2";"2";"NULL";"NULL"
etc.
What should work is doing a search and replace for ["NULL" = NULL].
In your case, because you have empty (blank) fields, you'll be looking at doing a search and replace like this:
[,, = ,NULL,]
And probably a second pass for NULL values at the end of a line like so:
[,\n = ,NULL\n]
Ancient question, but in case another MySQL noob like myself comes across it.
The find/replace rigamarole jmbertucci describes is avoidable if you're in charge of the creation of the CSV file, for example when you're backing up your own databases. In phpMyAdmin, if you select "custom" export method, you will see replace NULL with: and the default is NULL. Simply change that to "NULL" and you save yourself a step.
I ran into this same problem and jmbertucci's answer worked great. I did run into one additional problem. In the case with a row of data like such
"hello","world",,,,,,
which has multiple sets of null values in a row doing a search replace with [,, = ,NULL,] as jmbertucci suggested won't work as you intend it to on the first pass. Instead you'll end up with
"hello","world",NULL,,NULL,,NULL
You should continue to do the search replace to until you end up with 0 occurrences replaced
