Filtering Data Based On Select Parameter Values
Jun 6, 2006
Hi,
I am using SQL 2005. I have a SELECT query in a stored proc with 3 parameters:
@subaccount,@numDaysCutoff,@numDaysPcts. The proc needs to be modified to return data when subaccount values are any of these:
FRRIJ
FRRIC
FRMM
ROBECO
FRJV
MAIL
FRUKV
FRICE
Currently I use a WHERE condition and am able to get data correctly. However, for a NULL value I should get everything including those not in the above list. Should I use CASE statement instead? How?
@subaccount VARCHAR(8) = NULL
, @numDaysCutoff INT = 1
, @numDaysPcts INT = 1
SELECT Subaccount = ISNULL(h.subaccount, lo.subaccount)
, SecurityID = ISNULL(h.security_id, lo.security_id)
, SecurityName = s.name
, QtyHeldAndPending = ISNULL(h.quantity, 0) +
(CASE WHEN lo.type = 1 THEN lo.resulting_quantity * (-1)
WHEN lo.type = 2 THEN lo.resulting_quantity
ELSE 0 END )
, L.AverageDailyVolume
, XDaysVol = L.AverageDailyVolume * @numDaysPcts
, CutoffVol = L.AverageDailyVolume * @numDaysCutoff
, DaysVolHeld = h.quantity / NULLIF(L.AverageDailyVolume, 0)
, HeldPctNDaysVol = h.quantity / NULLIF((L.AverageDailyVolume * @numDaysPcts), 0) * 100
, TargetedHoldingsUSD = tm.ApprovedPortfolioTarget * iv.value_usd
, CutoffVolUSD = L.AverageDailyVolume * @numDaysCutoff * s.price_usd
, TargetedPctNDaysVol = (tm.ApprovedPortfolioTarget * iv.value_usd) /
NULLIF((L.AverageDailyVolume * @numDaysPcts * s.price_usd), 0) * 100
, DaysVolTargeted = (tm.ApprovedPortfolioTarget * iv.value_usd) /
NULLIF((L.AverageDailyVolume * s.price_usd), 0)
, NDaysCutoff = @numDaysCutoff
, NDaysPcts = @numDaysPcts
FROM subaccount_positions_table h --vGlobalHoldings h
JOIN iv_subaccount_table iv ON iv.subaccount = h.subaccount
FULL OUTER JOIN LiveOrders lo ON lo.subaccount = h.subaccount AND lo.security_id = h.security_id
FULL OUTER JOIN TM_DerivedSecurityTargetDetail tm ON tm.Subaccount = h.subaccount AND tm.SecurityID = h.security_id
LEFT JOIN dbo.security_table s ON s.security_id = COALESCE(h.security_id, lo.security_id)
LEFT JOIN dbo.SecurityLiquidity L ON L.SecurityID = h.security_id AND SourceID = 99
WHERE (h.subaccount = ISNULL(@subaccount, h.subaccount)
OR lo.subaccount = ISNULL(@subaccount, h.subaccount) )
AND status = 1
AND ( h.quantity > (L.AverageDailyVolume * @numDaysCutoff) -- qtyHeld > XDaysVol
OR -- Targeted Vol exceeds cutoff
ISNULL((tm.ApprovedPortfolioTarget * iv.value_usd), 0) >
ISNULL((L.AverageDailyVolume * @numDaysCutoff * s.price_usd), 0) -- Target > XDaysVol
)
ORDER BY ISNULL(h.subaccount, lo.subaccount), ISNULL(h.security_id, lo.security_id)
Thanks in advance!!!

I have a gridview connected to a sqldatasource, and it works pretty good. It gives me the subsets of the information that I need. But, I really want to let them choose all the companies and/or any status. What's the best way to get all the values in the gridview...besides removing the filters :)
I thought the company would be easy, I'd just set the selected value to blank "", and then it'd get them all....but that's not working. And, for the boolean, I have no idea to get the value without having a separate query.
(tabs_done=@tabsdone) and (company like '%' + @company + '%')1 <asp:DropDownList ID="drpdwnProcessingStatus" runat="server">
2 <asp:ListItem Value="0">Open</asp:ListItem>
3 <asp:ListItem Value="1">Completed</asp:ListItem>
4 </asp:DropDownList>
5
6
7 <asp:DropDownList ID="drpdwnCompany" runat="server">
8 <asp:ListItem Value="">All</asp:ListItem>
9 <asp:ListItem Value="cur">Cur District</asp:ListItem>
10 <asp:ListItem Value="jho">Jho District</asp:ListItem>
11 <asp:ListItem Value="sea">Sea District</asp:ListItem>
12 <asp:ListItem Value="san">Net District</asp:ListItem>

Is it possible to fill a parameter list with values based on another parameter value?
Here's what I have so far (which hasn't worked)...
I'd like to generate a report listing information for a student. The report viewer would first select a school from the first drop-down menu, and then the second drop-down menu would populate with the list of students at that school.
I have a dataset that calls a sp which returns a list of schools (SchoolID and SchoolName fields from the database table).
I have another dataset that calls a sp (with SchoolID as the parameter) which returns a list of students for that school.
Both datasets return the appropriate data when tested individually, but when I set up the Report Parameters and build the report, these errors come up...
The value expression for the query parameter '@SchoolID' refers to a non-existing report parameter 'SchoolID'.
The report parameter 'Student' has a DefaultValue or a ValidValue that depends on the report parameter "SchoolID". Forward dependencies are not valid.
...Is it possible for the reoprt to generate a list of available parameter values based on the value selected for another parameter?
Any help you can give me would be great!! Thank you

Hello, I am trying to use a boolean parameter to filter data in a table, but there is something I am missing.
Basically I want something like this:
I have a boolean parameter, "EP", and I have a filter set on my table as:
Expression Operator Value
=Fields!REFERRAL_SOURCE.Value = IIF (Parameters!EP.Value, "1297", ????)
Using the filter tab, I can't specify an expression for the 'Operator' so I was trying to work it out using either '=' or 'like'. What needs to go into the ???? in order for the referral source to be "not 1297" (i.e. the inverse of the filter)?
Or, am I completely missing an easy way to do this?
Thanks.

Data Scenario – Sitemaster entity has two attributes (Region and Country).
Region and Country are both domain-based attributes on separate entities [Region and . The Country entity has a domain based attribute on REGION.
Data relationship looks like this… REGION > COUNTRY
Customer Requirement
Customer would like the MDS UI to filter the Country drop-down options based on the Region selection.
To my knowledge – the only filtering that can be done is based on user security using Hierarchy Membership Permissions.

Hi everyone,
I have this semi-complex query that is selecting items from numerous tables residing on 2 different databases. So far the query works perfectly. Here is the problem: The user is given the option of selecting items based on whether a course is Completed (C) Incomplete (I) Passed (P) Failed (F) or (ALL). I am not really sure how to do the select all, the others I can do depending on the value...
Any thoughts??
Query:
sql Code:

Hi,
I have created a report using Report designer (Visual Studio, using Data Model as a data source), in the report I had created few datasets (with single filed) to populate the report parameters, lets say I have created a multi valued Parameter CustomerName and assigned field from a dataset,
result are coming correctly and combo box is getting populated but the customers are not in alphabetical order!
I want to sort it and need to specify it in report (please note that I am using Report Model as a data source and I can€™t sort the source table in the data base to get the result sorted)
Please let me know if anybody has done that or forward me if know some link which talks about it.
Thanks in advance.

Hi All,
I have requirement where first I need to show only one report
parameter. Based on user selection I need to prompt or show the user
another report parameter.
Say suppose I have 3 parameters. User selects first value in first
parameter I should not show the other 2 parameters. If user selects
second value in first parameter I should show second parameter and
hide third parameter. There is no relationship between these 2
parameters except user selection. Similarly if user third value in
first parameter then I should show third parameter and hide second
parameter.
Is this possible? I can not see any Visible property for report
parameters.
If yes, how to achieve this functionality?
Appreciate your help.

Raghu

I am a newbie to SQL Server.
I have a problem, in filtering the records returned by a query.
I have a table which contains 1 million records, it has a user defined primary key which is of character type.
The problem is i need to filter the output of a select query on the table based on two parameters i send to that query.
The first parameter will be the starting row number and the second one is the ending row number.
I need a procedure to do this.
For Eg:
MyProc_GetRowsFromBigTable(startRowNo,endRowNo) should get me only the rows in the specified range.
Thanks in advance,

Hello all. I hope someone can offer me some help. I'm trying to construct a SQL statement that will be run on a Dataset that I have. The trick is that there are many conditions that can apply. I'll describe my situation:
I have about 1700 records in a datatable titled "AISC_Shapes_Table" with 49 columns. What I would like to do is allow the user of my VB application to 'create' a custom query (i.e. advanced search). For now, I'll just discuss two columns; The Section Label titled "AISC_MANUAL_LABEL" and the Weight column "W". The data appears in the following manner:
(AISC_Shapes_Table)
AISC_MANUAL_LABEL W
W44x300 300
W42x200 200
(and so on)
WT22x150 150
WT21x100 100
(and so on)
MT12.5x12.4 12.4
MT12x10 10
(etc.)
I have a listbox which users can select MULTIPLE "Manual Labels" or shapes. They then select a property (W for weight, in this case) and a limitation (greater than a value, less than a value, or between two values). From all this, I create a custom Query string or filter to apply to my BindingSource.Filter method. However I have to use the % wildcard to deal with exceptions. If the user only wants W shapes, I use "...LIKE 'W%'" and "...NOT LIKE 'WT%" to be sure to select ONLY W shapes and no WT's. The problems arises, however, when the user wants multiple shapes in general. If I want to select all the "AISC_MANUAL_LABEL" values with W <= 40, I can't do it. An example of a statement I tried to use to select WT% Labels and MT% labels with weight (W)<=100 is:
Code SnippetSELECT AISC_MANUAL_LABEL, W
FROM AISC_Shape_Table
WHERE (W <= 100) AND ((AISC_MANUAL_LABEL LIKE 'MT%') AND (AISC_MANUAL_LABEL LIKE 'WT%'))
It returns a NULL value to me, which i know is NOT because no such values exist. So, I further investigated and tried to use a subquery seeing if IN, ANY, or ALL would work, but to no avail. Can anyone offer up any suggestions? I know that if I can get an example of ONE of them to work, then I'll easily be able to apply it to all of my cases. Otherwise, am I just going about this the hard way or is it even possible? Please, ANY suggestions will help. Thank you in advance.
Regards,
Steve G.

...and passing the exact same parameter values to with the following execute statement...
USE [Geomusdb]
GO
DECLARE @return_value int
EXEC @return_value = [petrander].[DynamicQuery]
@museum = 1,
@collection = 1,
@binomen = N'le',
@locality = N'Fakse'
SELECT 'Return Value' = @return_value
GO
gives me 0 rows!? What is different!?

While using a DateTime field, is there an easy way of filtering based on time of day? Ex. Anything that happened after 3:00 PM on any given day?
The easiest way I've found of doing so is :
Code:
SELECT *
FROM MyTable
WHERE ({ fn MOD(DATEDIFF(ss, '01/01/2000 00:00:00', [Date]), 3600 * 24) } >= DATEDIFF(ss, '00:00:00', '15:00:00'))
To me that seems a bit complicated... but it works...
Anyone that knows of a better way any help would be appreciated (or if you don't think there's a better way knowing that would help as well)

I have a few tables that have an disabled attribute using a BIT datatype. A lot of my queries on the front end look like:
SELECT *
FROM TableA
WHERE disabled <> 1
There's usually some other constraints on the query (get TOP 10 and greater than a certain date for example). Right now my tables are very small (only a couple thousand rows). I don't anticipate these tables having more than 100,000 rows.
Right now let's say there's only a CLUSTERED INDEX on the date field, and regular INDEXES on the identity field and perhaps some other UNIQUE name in the table.
Unless I am doing ranged queries on the CLUSTERED INDEXED field, I'm going to be performing table scans almost every time, right?
This sort of goes along with another question:
Say you run the following (SQL Server):
CREATE TABLE TestA (
[id] INT IDENTITY (1, 1) PRIMARY KEY,
disabled BIT DEFAULT 0
)
GO
INSERT INTO TestA (disabled) VALUES ('0')
GO
INSERT INTO TestA (disabled) VALUES ('0')
GO
INSERT INTO TestA (disabled) VALUES ('1')
GO
INSERT INTO TestA (disabled) VALUES ('0')
GO
INSERT INTO TestA (disabled) VALUES ('0')
GO
INSERT INTO TestA (disabled) VALUES ('0')
GO
INSERT INTO TestA (disabled) VALUES ('0')
GO
INSERT INTO TestA (disabled) VALUES ('1')
GO
INSERT INTO TestA (disabled) VALUES ('0')
GO
INSERT INTO TestA (disabled) VALUES ('0')
GO
INSERT INTO TestA (disabled) VALUES ('1')
GO
INSERT INTO TestA (disabled) VALUES ('1')
GO
INSERT INTO TestA (disabled) VALUES ('0')
Since [id] is a PK there will be a CLUSTERED INDEX placed on it. My question is; what does the optimizer do when you perform the following query?
SELECT TOP 3 *
FROM TestA
WHERE disabled <> '1'
My assumption is that since there's a CLUSTERED INDEX it will simply iterate through every tuple and check to see if disabled is not '1'. If my assumption is correct then these kind of boolean fields aren't a big deal if TOP queries are performed on a CLUSTERED INDEX.
So I guess what I am getting at is: Are bit attributes a sign of bad design? As tables get larger will performance degrade significantly? Would a better design be to have a seperate table of disabled items (which may result in large NOT IN subqueries)?
Any information on his would be greatly appreciated.

I understand that Multi-Select Parameters are converted behind the scenes to an In Clause when a report is executed. The problem that I have is that my multi-select string parameter is turned into an in claused filled with nvarchar/unicode expressions like:
Where columnName in (N'Value1', N'Value2', N'Value3'...)
This nvarchar / unicode expression takes what is already a fairly slow-performing construct and just drives it into the ground. When I capture my query with Profiler (so I can see the In Clause that is being built), I can run it in Management Studio and see the execution plan. Using N'Values' instead of just 'Value1', 'Value2','Value3' causes the query performance to drop from 40 seconds to two minutes and 40 seconds. It's horrible. How can I make it stop!!!?
Is there any way to force the query-rewriting process in Reporting Services to just use plain-old, varchar text values instead of forcing each value in the list to be converted on the fly to an Nvarchar value like this? The column from which I am pulling values for the parameter and the column that I am filtering are both just plain varchar.
Thanks,
TC

I want to filter out the duplicate rows based on three columns. I got this quick query from Microsoft site to filter out the duplicate rows, but I am getting the result that filters out the non-duplicate one too. Below is the query
;With Temp as (
SELECT row_number() over (partition by [id],[p_date], order by [id],[p_date],) as Row,
[code]...
In the above case id is null, but in some rows id is not null . The above is obviously not duplicate.

I have 2 tables each containing a material type. Table 1 contains material from their 3D application. Table 2 contains material with specific values that is not ours and we cannot rename or edit the data. I need a type of junction or mapping table that can connect the user material to the preset material. for example:
User Material = Wood-MDF
Preset Material = MDF Panel
I figured that i would make this table with 3 fields (ID, UserMaterialID, PresetMaterialID).How would i then construct a query view / Stored procedure that would return the Preset data values based on the user material id?

Ok I have a query "SELECT ColumnNames FROM tbl1" let's say the values returned are "age,sex,race".
Now I want to be able to create an "update" statement like "UPATE tbl2 SET Col2 = age + sex + race" dynamically and execute this UPDATE statement. So, if the next select statement returns "age, sex, race, gender" then the script should create "UPDATE tbl2 SET Col2 = age + sex + race + gender" and execute it.

Hello all,
I am using SQL Server in a project where I want to fetch the records that were inserted after a time specified in my query.
Suppose 10 records were inserted at 10:00 AM(morning) and 5 were inserted at 10:15 AM( 15 minutes later). I am running a query at 10:20 AM( 5 minutes after the second transaction). I need this query to be such that it selects the records inserted 10 minutes before. So it will show only the records inserted at and after 10:10 AM and willl not show those inserted at 10:00 AM.
Please help me in making such a query.
I am trying and I think that some Date & Time functions will help but still not able to achieve it.
Thanks in advance

Option 1 would be to filter by a range of value ie: WHERE member.age BETWEEN (@Start) AND (@End)
-say everyone between the ages of 50 through 80
Option 2 would be to filter by specific but multiple values ie: WHERE member.age IN (@Age)
-say anyone who is 25, 50 and 75.

I am using two drop downs, like so:

Selected="True" Text="All Cities" /></asp:DropDownList>
I have ????? in the value fields because I don't know what value needs to be passed to negate filtering (to choose all). The Dropdowns have the following SQLDatasources:<asp:SqlDataSource ID="ChurchStateDropData" runat="server" ConnectionString="<%$ ConnectionStrings:tceDatabaseOnlineSQLConnection %>" SelectCommand="SELECT DISTINCT [State] FROM [ChurchView]" DataSourceMode="DataReader"></asp:SqlDataSource>
<asp:SqlDataSource ID="ChurchCityDropData" runat="server" ConnectionString="<%$ ConnectionStrings:tceDatabaseOnlineSQLConnection %>" SelectCommand="SELECT DISTINCT [City] FROM [ChurchView] WHERE ([State] = @State)" DataSourceMode="DataReader"> <SelectParameters> <asp:ControlParameter ControlID="ChurchStateDrop" Name="State" PropertyName="SelectedValue" Type="String" /> </SelectParameters></asp:SqlDataSource>
Now, lets say I wanted to pass a value to the WHERE statement in ChurchCityDropData to coincide with 'All States', what would I replace value="??????" with? Now you may think I'm crazy to do such a thing, but this actually has to do with adding a Denomination Dropdown to show Denominations from all states or all cities. I will figure out the best logic for that later, I just want to know the wildcard to pass to the parameter to choose all states (negate filtering).
