Aggregation In A Hierarchy Involving Non-leaf Data.
May 22, 2008
NOTE: I apologize to anyone (especially moderators) who may notice that I am basically repeating a question that was already posted by me in another recent thread. The reason why I am reposting is because I want to filter my question down to its crux because the other question may not have been asked in the most clear way.
The Question:
The sceanrio is this.
(1) I have a sales person dimension with a hierarchy.
(2) In this hierarchy, Bill and Ted roll up to John.
(3) Bill sells 10 units, Ted sells 8 units, and John sells 5 units.
When you process this hierarchy, what would you expect the total to be for John?
(A) 23, which is the sum for Bill, Ted, and John
or
(B) 18, which is the sum of Bill and Ted only and overwritting John's number
I say (A) and I think most will choose the same, and all the examples I've been reflects (A).
However, in my simple cube I get (B).
Is there a setting I need to adjust to get (A)?

I have a multi dimensional cube. Among the dimensions I have, there is one dimension that has one hierarchy defined. When I view any of my measures on this hierarchy, I don't want the measures to be aggregated. I read some threads here having to do with semi additive behaviors, but Im not sure if it applies to my case. (or maybe it does and I'm just not getting it)
For example,
DimPerson
PersonID, PersonName, AnotherPersonID
1 , Person_A , null
2 , Person_B , 1
3 , Person_C , 1
The purpose of "AnotherPersonID" is to have a self join that describes a certain relationship. So, in this case, Person B and C are related to Person A. I describe this relationship using a hierarchy where A is a parent of B and C. However, I don't want the measures for Person_A to be replaced by the sum of the measures in Person_B and Person_C.
Why do I have a hierarchy if I don't want to sum the numbers? This is motivated by the need to dynamically report on A's numbers when B or C's numbers are reported. I'm just using persons as an example, but, in my case I have a bunch of members that can be paired with another member in that dimension. And when I report on a member that joins to another member in that dimension, I need to dynamically report on that member's measures as well.
Lastly, If the use of a hierarchy is not the best approach for this, would you recommend another approach?

Env: SQL Server 2012
I'd like to import some tables into MDS entities.
So I found MDSModelImport Program.
Importing is worked. And I confirmed to imported columns of tables as leaf Attributes.
I tried to insert data. But In Explorer Leaf Attributes are not shown except Code and Name.
So I couldn't insert data. In Excel also it does.

I'm a newbe in the realm of database reporting. At my current position, I'm reporting off of CRM databases using Crystal V-11. Previously I'd experience working with HR databases using the same reporting tool. I am interested in progressing to work with database design and scripting. Any suggestion from anyone on which certifications to pursue?
Thanks.

eventually I started using DERIVED Tables and Sub queries within them if needed. I like choking down all the queries in the selects joining them and having your result set select there to choose from all the aliases, it also resolves while doing this. So much easier IMO than using CTE's or TEMP Tables. I was big on temp tables for a while...
I'm curious though if you want to count a type of criteria in a column do you use a standard case in your inner query choking it down just for those particular counts? Then do another case on the other criteria and END AS with the alias name?
E.G.
CASE WHEN COLUMN1 = PIZZA THEN COUNT(COLUMN1) END AS PIZZACOUNT
CASE WHEN COLUMN1 = ROOTBEER THEN COUNT(COLUMN!) END AS ROOTBEERCOUNT
ETC...........

I manage a legacy system that dumps it's data into a number of different databases (same schema) on a nightly basis using bulk insert. I need to formulate a strategy for efficiently aggregating that data into a single database right after these nightly extractions complete. Here is my current stategy:
1. Duplicate the legacy system's database schema and add an identifier column to specify which database the data loaded from.
2. Each night, delete all records in the table.
3. Each night, for each database:
3a. Set each table's default value to a value that references the current database being loaded.
3b. Use the legacy system's flat files and format files to bulk insert into the database.
3c. Clear the default value.
What other steps would faciliate performance? Dropping and recreating the indexes? Does anyone forsee faults in this strategy?
Thanks,
Matt

How can I get the data from a table that stores hierarchical information keeping the right order and hierarchy levels?
I also need to specify a first level....let me explain.
Table: Sites
Id (PK)
Title
Url
ParentId
If I have something like this:
1 | Test | http://localhost | NULL
2 | Sub-Test | http://localhost/subtest | 1
3 | SecondItem | http://anotherServer | NULL
4 | ChildOfSub-Test | http://localhost/subtest/child | 2
And I specify that I want all child items below the Id 2, it must return:
Id | Title | Url | ParentId | Depth
2 | Sub-Test | http://localhost/subtest | 1 | 0
4 | ChildOfSub-Test | http://localhost/subtest/child | 2 | 1
How can I do this? I've saw some examples with CTEs, but they always return all of the items.

After having built a decision tree model to predict a boolean output attribute using 64-bit SQL Server 2005 (build 9.0.3054), we have observed that predictions for some cases are being done at non-leaf nodes in the tree.
Specifically, after executing a prediction join which returns:
- CaseTable.CaseID
- MiningModel.OutputAttribute
- PredictProbability(MiningModel.OutputAttribute)
- PredictNodeId(MiningModel.OutputAttribute)
and comparing the values of PredictNodeID(MiningModel.OutputAttribute) with the mining model content column [NODE_UNIQUE_NAME] to determine the actual "rule" used to make the case-level prediction.
We have observed that for a subset of cases, predictions are being made at nodes in the tree that are not leaf nodes. Specifically, predictions are being made at a node that is 3 levels deep. The leaf nodes below this inner-tree node are 2 levels further down the tree.
Also supporting the fact that that predictions are being made at this non-leaf node is that the PredictProbability corresponds exactly with the output attribute distribution at this non-leaf node.
In this particular application, we would have obtained better results if the predictions were made at the leaf-nodes.
A few questions:
1. Why are predictions with decision trees made at non-leaf nodes?
2. Is there a way to "force" predictions to occur at leaf nodes via DMX?
Thanks in advance for any information or advice.

I have the following scenario. I want to apply some calculations on different levels and then aggregate them up.
First measure calculates at Productgroup,color,store,size level
ProductGroup Color Store Size Amount Quantity
Measure:Amount*Quantity (ProductGroup, Color, Store, Size)
A Blue Store A L 100 6 600
A Red Store A S 150 4 600
A Green Store A M 160 7 1120
B Blue Store A L 300 3 900
[Code] ........
The other measure ignores color
ProductGroup Store Size Amount Quantity
Measure:Amount*Quantity (ProductGroup, Store, Size)
A Store A L 100 6 600
A Store A S 150 4 600
A Store A M 160 7 1120
B Store A L 640 15 9600
[Code] ...
Ignoring that gives another figure for productgroup B. In the pivot, I should see both measures at whatever attribute, except for the measure that excludes color will be null if tried split on color
ProductGroup Amount Quantity (ProductGroup, Color, Store, Size) (ProductGroup, Store, Size)
A 410 17 2320 2320
B 640 15 2820 9600
C 170 5 430 430
How should the two measure be defined:
Measure (ProductGroup,Color,Store,Size)
Measure (ProductGroup,Store,Size)

Out of nowhere my derived hierarchies starting showing the following message in the MDS UI
No Level Defined: This Derived Hierarchy is incomplete......
As you can see below the structure is defined and still in tact. This message shows up in by the Explorer & System Admin areas. I'm also able to query the subscription view setup without any issue.
This is with 2012 w/ no CUs. Same setup in running in another environment without issue.

At the 2nd level, the calculated measure will only be correct if it is Averaged. And at the 1st level, the calculated measure will only be correct to take these Average value from 2nd level and Sum then up together.
Level 1 Level 2
A
X1
X2
=================
(Avg of X1 + X2)
B
Y1
Y2
Y3
=================
(Avg of Y1 + Y2 + Y3)
===================================================
(Sum of (Avg of X1 + X2) + (Avg of Y1 + Y2 + Y3) )
Currently, Instead of summing all the 3 averaged value, it is averaging against all the items like,
(Avg of X1 + X2 + Y1 + Y2 + Y3)
My MDX currently looks something like that
[Measure].[Value] / [Dimension].[Attribute.count] -> so i can get the avarage at the 2nd level but it doesn't require on the 1st level but retaining this value.
How can i do an average on the leaf level and using these average values to sum at parent level?

I have a time dimension which has Date, Week, Month and Year. However, the hierarchy will have only Week, Month and Year. It works great for any Sales measure with AggregateFunction as SUM.
I have created a new measure with AggregateFunction = LastNonEmpty. Also in the backend, I have pushed all the inventory data to last date in every month as inventory is always looked on a monthly basis not on a weekly basis. This measure shows correct data for every last week of the month in the hierarchy. However, Months and Years are displayed as zeros.

Hello,
I have a DTS package that migrates data from Excel to Access to SQL Server. Before that occurs, at the very beginning, I have a delete script that deletes the existing data in the Access database. When I hit that first step, it gives me the error:
Microsoft JET Database Engine (-2147467259) - The Microsoft Jet database engine cannot open the file '<path to access .mdb>'. It is already opened exclusively by another user, or you need permission to view its data.
I checked the permissions and the account that the web site is running under (impersonated) has full permissions to the file. Also, I am running the web site on my machine, I'm triggering the DTS package through .NET code, the access database is on a file/print server, and the SQL Server is a separate machine.
I'm thinking that maybe the issue is that the access database is on a separate machine, but I'm not quite sure.

Hi All,
I have a table called [History] with the following fields and types.
Date(datetime), PriceZone(varchar), ProductID(varchar), ProductName(varchar), Category(varchar), SubCategory(varchar), Price(decimal 2 places), Cost(decimal 2 places), Units(Big Int), DollarSales(decimal 2 places), Margin(decimal 2 places), Profit(decimal 2 places)
Each record represent information for each ProductID, per PriceZone, per Date. There's always one record per product; per zone; per Date.
Here is the sample of the records (Just for example I am just using one product in one zone)
Date, PriceZone, ProductID, ProductName, Category, SubCategory, Price, Cost, Units, DollarSales, Margin, Profit
2008-04-30,Zone1,001,Lays Chips,Snacks,Chips,2,1.5,10,20,25,5
2008-04-29,Zone1,001,Lays Chips,Snacks,Chips,2,1.5,8,16,25,4
2008-04-28,Zone1,001,Lays Chips,Snacks,Chips,2,1.5,15,30,25,7.5
2008-04-25,Zone1,001,Lays Chips,Snacks,Chips,2,1.5,13,26,25,6.5
2008-04-22,Zone1,001,Lays Chips,Snacks,Chips,2,1.5,11,22,25,5.5
2008-04-21,Zone1,001,Lays Chips,Snacks,Chips,1.98,1.5,15,29.7,24.24,7.2
2008-04-20,Zone1,001,Lays Chips,Snacks,Chips,1.98,1.5,15,29.7,24.24,7.2
2008-04-19,Zone1,001,Lays Chips,Snacks,Chips,1.95,1.5,18,35.1,23.08,8.1
2008-04-16,Zone1,001,Lays Chips,Snacks,Chips,1.9,1.5,20,38,21.05,8
2008-04-15,Zone1,001,Lays Chips,Snacks,Chips,1.8,1.5,40,72,16.67,12
2008-04-10,Zone1,001,Lays Chips,Snacks,Chips,1.8,1.5,32,57.6,16.67,9.6
2008-04-09,Zone1,001,Lays Chips,Snacks,Chips,1.8,1.5,27,48.6,16.67,8.1
2008-04-08,Zone1,001,Lays Chips,Snacks,Chips,1.8,1.4,29,52.2,22.22,11.6
2008-04-01,Zone1,001,Lays Chips,Snacks,Chips,1.8,1.4,30,54,22.22,12
Now using the table information, I want to run a script to get the following fields;
Date, PriceZone, ProductID, ProductName, Category, SubCategory, Price, Cost,UnitsSum_ForLast4Dates, UnitsSum_ForLast12Dates, DollarSalesSum_ForLast4Dates, DollarSalesSum_ForLast12Dates, AvgMargin_ForLast4Dates, AvgMargin_ForLast12Dates, ProfitSum_ForLast4Dates, ProfitSum_ForLast12Dates
So output in the above example would be;
Date, PriceZone, ProductID, ProductName, Category, SubCategory, Price, Cost,UnitsSum_ForLast4Dates, UnitsSum_ForLast12Dates, DollarSalesSum_ForLast4Dates, DollarSalesSum_ForLast12Dates, AvgMargin_ForLast4Dates, AvgMargin_ForLast12Dates, ProfitSum_ForLast4Dates, ProfitSum_ForLast12Dates
2008-04-30,Zone1,001,Lays Chips,Snacks,Chips,2,1.5,46,224,92.00,424.70,25,22.30,5.00,88.70
Here;
Date is the maximum date available in the entire [History] table. Meaning the "Date" value will be same for all the records in the output.
Price is the Price for that product in that zone on Date
Cost is the cost for that product in that zone on Date
About "Last4Dates" & "Last12Dates":
"Last4Dates" is the last 4 dates in the entire table from 'Date" value , including "Date" value and prior 3 dats before the "Date" value. In the above data set example it would be from "2008-04-25" to "2008-04-30"
"Last12Dates" is the last 12 dates in the entire table from 'Date" value, including "Date" value and prior 11 Dates before the "Date" value. In the above data set example it would be from "2008-04-09" to "2008-04-30"
UnitsSum_ForLast4Dates and UnitsSum_ForLast12Dates is the sum of Units for 4 and 12 weeks respectively; per product, per zone
DollarSalesSum_ForLast4Dates and DollarSalesSum_ForLast12Dates is the sum of DollarSales for 4 and 12 weeks respectively; per product, per zone
AvgMargin_ForLast4Dates and AvgMargin_ForLast12Dates is the Average of DollarSales for 4 and 12 weeks respectively; per product, per zone
ProfitSum_ForLast4Dates and ProfitSum_ForLast12Dates is the sum of Profit for 4 and 12 weeks respectively; per product, per zone
How Can I achieve this in SQL?
Can someone please help me as soon as possible.
Thanks,
Zee

We're experiencing a large number of deadlocks since we began runningSQL Server 2000 Enterprise Edition SP3 on a Dell 6650 with hyperthreading intel processors. We don't have the same problem on Dell6650's w/o the hyper threading. If I turn off the parallel queryprocessing option the deadlocks stop. I've tried all of the suggestionsfrom the Microsoft Knowledge Base under the following link -http://support.microsoft.com/?kbid=837983The only suggestion that actually yielded results was turning offparallel query processing but I don't want to give up what should be aperformance advantage if it wasn't for the deadlocks. Query tuning andindex tuning hasn't helped. Any suggestions? I haven't applied SP4yet.

Hello, this is probably the most helpful forum I have found on the Net in awhile and you all helped me create a DB for my application and I have gotten kind of far since then; creating stored procedure and so forth. This is probably very simple but I do not yet know the SQL language in depth to figure this problem out. Basically I have a printer monitor application that logs data about who is printing (via logging into my app with a passcode, which is located in the SQL DB), what printer they are using, and the number of pages. I have 3 tables, one called 'jobs' which acts like a log of each print-job, a user table (which has data like Name=HR, Passcode=0150) and table listing the printers. Each table uses an integer ID field which is used for referencing and so forth. Tables were created with this command sequence:
create table [User_Tbl](
[ID] int IDENTITY(1,1) PRIMARY KEY,
[Name] varchar(100),
[Password] varchar(100),
)
go
create table [Printer_Tbl(
[ID] int IDENTITY(1,1) PRIMARY KEY,
[Name] varchar(100),
[PaperCost] int
)
go
create table jobs(
[JobID] int IDENTITY(1,1) PRIMARY KEY.
[User_ID] int,
Printer_ID int,
JobDateTime datetime,
NumberPrintedPages int,
CONSTRAINT FK_User_Tbl FOREIGN KEY ([User_ID])
REFERENCES [User_Tbl]([ID]),
CONSTRAINT FK_Printer_Tbl FOREIGN KEY ([Printer_ID])
REFERENCES Printer_Tbl([ID])
)
go
I need display some data in a datagrid (or whatever way I present it) by using a query. I can do simple things and have used a query someone on here suggested for using JOINS, and I understand but I can't figure out how to make this particular query. The most necessary query I need for my report needs to look like this: (this will be from a data range @MinDate - @MaxDate)
Username PagesOnPrinter1 PagesOnPrinter2 TotalPagesPrinted Cost
--------- ---------------- --------------- ---------------- ----
HR 5 7 12 .84
Finance 10 15 25 1.75
So it gives the username, how many pages printed on each printer, the total pages printed, and the total cost (each printer has a specific paper cost, so it is like adding the sum of the costs on each printer). This seems rather simple, but I cannot figure out how to translate this to SQL.
One caveat I have is that the number of printers is dynamic, so that means the the columns are not really static. Can this be done? And if so how can I go about it? Thanks everyone!

[DateCurrentStatus] [datetime] NULL,
[FormType] [varchar](10) NOT NULL,
) ON [PRIMARY]
There can be more than one record per FirstName, LastName. FormType can be N for new or D for departing.
I want to do this for each record:
Read the FormType and Department from the record with the most recent activity (SubmittedDate) for each user
Convert Department to a 4 character department number
Update CurrentStatus with (FormType concatenated with the 4 character dept number) in all records for that user.
I have created another table called UserMostRecent which contains the most recent record for each user.
I have written a query to do this by brute force (read a record, set local variables, update a record), but I would like learn a simpler way to do it. I don't understand the syntax of CASE because it seems to change depending on where it is used.
Here is what I have tried that does not work. Error is "Incorrect syntax near word CASE"
UPDATE HelpDesk_NewUser
SET DateCurrentStatus = b.DateMostRecent,
CurrentStatus = (b.FormType + a.Department
CASE
WHEN 'Roads Department' THEN '3000'
WHEN 'Engineering and Survey Services' THEN '1900'
WHEN 'Waste Management' THEN '8999'
WHEN 'Kern Air Pollution Control District' THEN '9149'
WHEN 'Environmental Health' THEN '4113'
WHEN 'Building Inspection' THEN '2625'
WHEN 'Animal Control' THEN '2760'
WHEN 'Planning Department' THEN '2750'
WHEN 'Community and Economic Development' THEN '5940'
WHEN 'Resource Management Agency' THEN '2730'
WHEN 'Code Compliance' THEN '2620'
WHEN 'Roads Kern Regional Transit' THEN '8998'
END)
FROM HelpDesk_NewUser a JOIN UserMostRecent b
ON (a.LastName = b.LastName and a.FirstName = b.FirstName)
Thank you, forum participants. You are the best!

Here are the tables I am dealing with:
Tables
license TABLE
---------------
license_id int PK
vendor_id int FK
po_id int FK Nulls
license_type_id int FK
lic_user_id int FK Nulls
location_id int FK Nulls
lic_start_date smalldatetime Nulls
days_allowed int Nulls
serial_num varchar(50) Nulls
activation_key varchar(50) Nulls
max_users int Nulls
comments varchar(1000) Nulls
software TABLE
------------------
software_id int PK
os_id int
software_name varchar(150)
comments varchar(1000) Nulls
software_license TABLE
--------------------------
license_id int PK , FK
software_id int PK , FK
comments varchar(1000) Nulls
dept_license TABLE
---------------------
dept_id int PK , FK
license_id int PK , FK
comments varchar(1000) Nulls
purch_order TABLE
---------------------
po_id int PK
po_number varchar(50)
po_date smalldatetime
comments varchar(1000) Nulls
dept_purch_order TABLE
----------------------------
po_id int PK , FK
dept_id int PK , FK
comments varchar(1000) Nulls
I am using the following stored proceedure to try to create a useful report from those tables:
Code Block
ALTER PROCEDURE [dbo].[ListDepartmentLicenses]
@Department int,
@Software int
AS
BEGIN
SET NOCOUNT ON;
SELECT dept_license.license_id,
license.lic_start_date,
department.dept_name,
purch_order.po_number,
software.software_name
FROM dept_license
JOIN license
ON dept_license.license_id = license.license_id
JOIN department
ON dept_license.dept_id = department.dept_id
JOIN dept_purch_order
ON dept_purch_order.dept_id = dept_license.dept_id
JOIN purch_order
ON dept_purch_order.po_id = purch_order.po_id
JOIN software_license
ON dept_license.license_id = software_license.license_id
JOIN software
ON software_license.software_id = software.software_id
WHERE (department.dept_id = @Department or @Department Is Null) and
(software.software_id = @Software or @Software Is Null)
ORDER BY license.lic_start_date
END
The sproc compiles fine but I get no rows returned.

I seem to have a little problem with my SQL. I'm attempting to use a an .NET grid-view to page a list of search results using an ObjectDataSource (ODS). It's a very simple search setup. The ODS retrieves the Search keyword from the query-string sending it to the BLL's GetResult method which then utilises the DAL's version and retrieves the result. Not all of them of course because I'm paging so it only retrieves the first page (Lets say the first 10 items). This part of the SQL works fine as the same SQL method is used else where on the site and it's well tested. But to to use the Paging function I'm using the SelectCountMethod attribute of the ODS. Again this gets the Search term from the QueryString and sends it too the BLL which retrieves the information from the DAL. Now this is where it starts playing up. The Sql count method is as follows and is run as a Stored Procedure: 1 ALTER PROCEDURE dbo.StoreName_Store_GetProductSearchCount
2 (
3 @SearchQuery nvarchar
4 )
5 AS
6 SET NOCOUNT ON
7
8 SELECT COUNT(*)
9 FROM StoreName_Products
10 WHERE Title LIKE '%' + @SearchQuery + '%'
Nice and Easy. Not a Problem... Isn't it? When I run this query by selecting the database in the Server Explorer in VS2005 and running a 'New Query', it retrieves the correct results. (I only run this query from the Start of the SELECT Query in this mode, don't add the stuff above it)When I run this query through the website as intended and retrieves the int from the Stored Procedure, it always returns the entire count of the number of products in the table.At first I thought It might be a simple error with my caching system. Nope, it's not as after I purged it, it still returns the same value. I thought, well maybe just maybe the BLL or the DAL are some point converting it to this number but I'm quite sure it wasn't... and nope it wasn't that either because the ExecuteScalar method was found to be returning this number. So I ran the Stored Procedure by opening it up and simply right clicking the SQL Query and Executing it adding a value for @SearchQuery when it requested. Bingo. It's returning the full number of the products.So my question is... What's the deal? How can the same query return two completely different results? and most of all... How do I overcome this? Is this because it's in a stored procedure and I should be executing it as a SqlCommand from my DAL? I'm a bit confused. Is there a problem running this sort of query in a stored procedure that I don't know about and probably really should?Thankful for any answers,Regards,Luke

I am trying to write a stored procedure which would execute following logic:
- The stored procedure takes 2 optional parameters @StartDate and @EndDate
@StartDate Datetime = null
@EndDate Datetime = null
- Since the parameters are optional user can enter either one or can leave both blank.
- If user doesnot enter any values for SD (start date) and ED (end date), stored procedure should run select query replacing those values with wildcard character '%' or NULL
- If user enters SD, query should use @StartDate as the SD and GetDate() as the ED
- If user enters ED, query should use @EndDate as the ED and MIN() of the Date field as SD
I was able to write query which did almost everything as is stated above expect for incorporating NULLs
The query is as below
CREATE PROCEDURE SearchDocumentTable
@FName varchar(100) = null,
@LName varchar(25) = null,
@ID varchar(9) = null,
@StartDate Datetime = null,
@EndDate Datetime = null
AS
IF ( @StartDate IS NULL)
Select @StartDate = MIN(DateInputted) from Document
Select
FName as 'First Name',
LName as 'Last Name',
ID as 'Student ID',
Orphan as 'Orphan',
DocumentType as 'Document Type',
DocDesc as 'Description of the Document',
DateInputted as 'Date Entered',
InputtedBy as 'Entered by'
From Document,DocumentTypeCodes
Where FName LIKE ISNULL(@FName,'%')
AND LName LIKE ISNULL(@LName,'%' + NULL)
AND ID LIKE ISNULL(@ID,'%' + NULL)
AND (DateInputted BETWEEN @StartDate AND ISNULL(@EndDate,GETDATE()) OR DateInputted IS NULL)
AND Document.DocTypeCode = DocumentTypeCodes.DocTypeCode
GO
Any help would be appreciated
Thanks in advance :)

Hello friends,
I am inserting non-english strings into my database table from my java program.
Code Snippet
sql = "insert into static_string1 values (?)";
PreparedStatement statement=connection.prepareStatement(sql);
statement.setString(1,statString);
where, statString is a string variable containing Hebrew characters.
Till here, my code works fine. i.e, Hebrew characters are properly inserted to the database.
The problem is when I try to retrieve the String_Id based upon the statString I inserted to the table static_string1.
Code Snippet
String sql = "select String_Id from Static_String1 where String like ('" + statString +"')";
Statement statement=connection.createStatement();
ResultSet rs=statement.executeQuery(sql);
rs.next();
int stringId=rs.getInt("String_Id");
I tried hardcoding the string in the query and to execute it from the SQL Server Management Studio as below
Code Snippetselect String_Id from Static_String1 where String like( ' הזח' );
But even this is returning null rows, even though the entry is present in the table Please help me out asap.
Please pardon me if this is not the right section to post my doubt. I didnt find any other relevant section here.
