I am building a report with Microsoft SSRS (2012) having a multi-value parameter #parCode for the user to filter for certain codes. This works perfectly fine. Generally, my query looks like this:
SELECT ...
FROM ...
WHERE
TblCode.Code IN (#Code)
ORDER BY...
The codes are of following type (just an excerpt):
C73.0
C73.1
...
C79.0
C79.1
C79.2
Now, in additon to filtering for multiple of these codes I would like to als be able to filter for sub-strings of the codes. Meaning, when the user enters (Example 1)
C79
for #parCodes The output should be
C79.0
C79.1
C79.2
So eventually the user should be able to enter (Example 2)
C73.0
C79
for #parCodes and the output would be
C73.0
C79.0
C79.1
C79.2
I managed to implement both functionalities seperately, so either filtering for multiple "complete" codes or filterting for sub-string of code, but not both simultaneously.
I tried to do something like
...
WHERE
TblCode.Code IN (#parCode +'%')
ORDER BY...
but this screws up the Example 2. On the other hand, if I try to work with LIKE or = instead of IN statement, then I won't be able to make the parameter multi-valued.
Does anyone have an idea how to realize such functionality or whether IN statement pared with multi-valued parameters simply doesn't allow for it?
Thank you very much!
Assuming you are using SQL server
WHERE (
TblCode.Code IN (#parCode)
OR
CASE
WHEN CHARINDEX('.', Code)>0 THEN LEFT(TblCode.Code, CHARINDEX('.', TblCode.Code)-1)
ELSE TblCode.Code
END IN (#parCode)
)
The first clause makes exact match so for your example matches C73.0
The second clause matches characters before the dot character so it would get values C79.0, C79.1, C79.2 etc
Warning: Filtering using expressions would invalidate the use of an index on TblCode.Code

The following query (qryCurLotNewProducts) produces a data set that I want process further with another query (qryBNP_CFRecordset):
//qryCurLotNewProducts
SELECT tblNewProducts.*
FROM tblNewProducts INNER JOIN tblCurLot ON (tblCurLot.CatalogNum = tblNewProducts.CatalogNum) AND
(tblNewProducts.LotNum = tblCurLot.CurLot);
When I run this second query to list only the "CF" products found in the first query, I get the `Data type mismatch in criteria expression' error.
//qryBNP_CFRecordset
SELECT qryCurLotNewProducts.*, tblABCategory.UNSPSC, tblAmount.ProductSize
FROM tblAmount RIGHT JOIN (tblABCategory RIGHT JOIN qryCurLotNewProducts ON tblABCategory.ABCategory = qryCurLotNewProducts.ABCategory) ON tblAmount.Amount = qryCurLotNewProducts.Amount
WHERE (((qryCurLotNewProducts.CatalogNum) Like "A700-###CF") AND ((qryCurLotNewProducts.DateEntered) Between #1/1/2000# And #3/1/2020#))
ORDER BY qryCurLotNewProducts.CatalogNum, Abs(qryCurLotNewProducts.LotNum);
If I remove the CF from the search string (so "A700-###"), the query correctly outputs a list containing all items that contain that pattern:
If I use strings like "A700-####F" or "A700-###ZZ" or other combinations like that, I don't get an error but rather an empty results set.
Notably, "A700-001CF", "A700-002CF", etc all create the data type error. It seems there is something about the CF key combination that is causing trouble.
Has anybody else ever seen this issue? Do I need to use some kind of delimiter to tell SQL to not view CF as some kind of special switch?
Abs(qryCurLotNewProducts.LotNum) wont work with the values for Products ending in CF. Your LotNum-Column has a text-type.
Edit: Your LotNum-Column has a text-type as you can see in your first screenshot.
I am attempting to write a query for an Altiris report. This query is looking for machine information. The query works fine, however the problem I am running into is with my parameters. I have set up multiple parameters within Altiris to allow me to filter and search through the report for multiple fields. Then, in my query, I add those parameters into the WHERE statements.
All of the parameters were working fine, until I added Make and Model parameters. We have quite a few machines that do not have information populated into these fields. So when I add in the WHERE xxxx LIKE N'%Make%', I lose about 500 machines based on it now only looking for machines with something in that field. I tried to fix this by adding lines like the following:
Where ((xxxx LIKE N'%Make%' OR xxxx is null))
This kind of worked, in that now the report shows all machines... But if I enter "HP" into the Make parameter field and then rerun the report... it shows all HP machines like I want, but also all of the null machines as well.
How can I rewrite my where statements so that they do not exclude machines in the report, and allow me to filter by all HP machines, without showing null values as well?
Hope this made sense, and thank you
In this snip of code, the last two lines make me lose about 500 machines in my total machine count of the report. It is omitting all machines that have null values.
WHERE
(dbo.OS_Version.[OS Name] LIKE N'%OSName%') AND
(dbo.OS_Version.[OS Version] LIKE N'%Build%') AND
(dbo.OS_Version.Name LIKE N'%Name%') AND
(dbo.Inv_AeX_AC_Identification.[Hardware Serial Number] LIKE N'%Serial%') AND
(dbo.vHWComputerSystem.Manufacturer LIKE N'%Make%') AND
(dbo.vHWComputerSystem.Model LIKE N'%Model%')
This is how I tried to fix it, and now I get all 20,000 machines. But my make/model fields report on null fields as well.
WHERE
(dbo.OS_Version.[OS Name] LIKE N'%OSName%') AND
(dbo.OS_Version.[OS Version] LIKE N'%Build%') AND
(dbo.OS_Version.Name LIKE N'%Name%') AND
(dbo.Inv_AeX_AC_Identification.[Hardware Serial Number] LIKE N'%Serial%') AND
((dbo.vHWComputerSystem.Manufacturer LIKE N'%Make%') OR (dbo.vHWComputerSystem.Manufacturer is null)) AND
((dbo.vHWComputerSystem.Model LIKE N'%Model%') OR (dbo.vHWComputerSystem.Model is null))
I'm guess that if you don't enter a value for a parameter, it's coming through as an empty string, and of course, every varchar is LIKE '%%'.
I'm not sure what RDBMS this is, but if the ISNULL function is available, try this:
where ((ISNULL(xxxx,'') LIKE N'%Make%')
This replaces nulls with the empty string before doing the LIKE comparison.
I think you want something like this:
(cs.Manufacturer LIKE N'%#Make%' OR #Make = '') AND
(cs.Model LIKE N'%#Model%' OR #Model = '')
I am using = '' rather than IS NULL because you are clearly not passing in the parameters as NULL values (the LIKE wouldn't work).
This does not provide a method for filtering to get only the NULL values, because you are using the "special value" for the parameter to mean "don't apply a filter here".
Note that cs is intended as a table alias. I also strongly recommend that you use table aliases so your queries are easier to write and to read.
I think you're looking for something like WHERE ISNULL(Model, '') LIKE '%Model%'. However, you should replace '%Model%' with a variable. The above example would literally match the word 'Model'
DECLARE #Model NVARCHAR(100) = 'T-800'
...
WHERE ISNULL(Model, '') LIKE '%' + #Model + '%'
^ This would not include rows with NULL Model values
I'm building a SSRS report and would like one of my parameters to be optional where data is entered or not.
Here is an example query for a better understanding:
SELECT
C1
,C2
,C3
FROM
db_Database..tb_Table
WHERE
tb_Table_DateTime between [THEN] and [NOW]
AND
tb_Table_Integer IN (#Integer)
I'm trying to work out if, in my query, I can ignore the whole:
AND tb_Table_Integer IN (#Integer)
line if user chooses not to input any number.
Bascially, I want all data returned unless specified otherwise via #integer.
If not possible in the query, can this be achieved in the Visual Studio?
Cheers.
This is typically handled by doing:
WHERE . . . AND
(#Integer IS NULL OR tb_Table_Integer = #Integer)
Do not use IN (#Integer). It sort of implies that you think that #Integer could be a list. That is not possible.
The most common way to do this is with coalesce or nullif. Like this:
WHERE coalesce(#integer,tb_Table_Integer) = tb_Table_Integer
Suddenly I've realized that while this works in groovy just like it is expeceted:
Sql.newInstance(connectionParams).rows("SELECT FROM ITEMS WHERE id = ?", [200])
this won't work
Sql.newInstance(connectionParams).rows("SELECT FROM ITEMS WHERE name LIKE '%?%'", ["some"])
All you can get is
Failed to execute: SELECT FROM ITEMS WHERE name LIKE '%?%' because:
The column index is out of range: 1, number of columns: 0.
My questions are:
Is it intentionally implemented this way? I've never needed to have a parametrized text search, so I'm not sure where this behaviour is typical or not.
How can I nevertheless safely parametrize statement with text search in it?
I believe you want to include the %'s in the parameter, like:
Sql.newInstance(connectionParams).rows("SELECT FROM ITEMS WHERE name LIKE ?", ["%some%"])
I have inherited a MS database, to work from, this database also links to other programs so I don't want to change the database tables itself.
I'm using Visual Basic 2010,
What I need to do is have a range of filters on this table and then one extra filter entered by the user.
e.g. they enter '50' and range '5' I need to search the dataset using the range of '45 to 55'
This is my code so far for the dataset:
SELECT [CUTTER NO]
,CUTTER_ID
,[SIZE-Inches]
,[MM-Across]
,[MM-Round]
,TYPE
,[LEADING EDGE]
,[CUTTER TYPE]
,ACROSS
,ROUND
,[WIDTH PAPERmm]
,[GAPS ACROSSmm]
,[GAPS ROUNDmm]
,[Serial Number]
,[T G]
,Repeat
,[Repeat MM]
,[L&G]
,Notes
FROM [Cutter List]
WHERE (TYPE <> 'DISCONTINUED')
AND (TYPE <> 'SPEC')
AND (CUTTER_ID <> NULL)
AND ([CUTTER TYPE] = 'MP')
AND (TYPE <> 'BUTT')
ORDER BY CUTTER_ID, [MM-Across]
What I need to type into this SQL is:
WHERE [MM-Across] LIKE #[MM-Across] and [MM-Round] LIKE #[MM-Round]
Which from what I can tell on the net is wrong as I cannot have [] in a where.
I even tried :
SELECT [MM-Across] AS mmacross
FROM [Cutter List]
WHERE ('mmacross' LIKE '#mmacross')
This it accepts but I get an different error appear saying
"The Schema returned by the new query differs from the base query."
What am I doing wrong? I don't understand the last error or how to avoid this.
Two things:
You can definitely have brackets "[..]" in WHERE clauses, they just have to be in the correct places (just like anywhere else), and
You cannot use the brackets in variable or parameter references, and that means that, unlike columns, you cannot have special characters in their names, like "-" in "#MM-Across", so just change your parameter names to something like "#MM_Across".
Note that the column names are fine, it's your parameter and/or variable names that you have to change (I cannot tell which these are from your snippet).
So instead of this:
WHERE [MM-Across] LIKE #[MM-Across] and [MM-Round] LIKE #[MM-Round]
Try this:
WHERE [MM-Across] LIKE #MM_Across and [MM-Round] LIKE #MM_Round
Of course, you will also have to change the parameter/variable names wherever they are declared and passed in. If you post the code that does this, I can show you how to change that also (thoguh it may be obvious by now).
