I want to distinguish between static SQL, dynamic SQL, and embedded
SQL, but couldn't find too much useful resources in the web.
For example, if we put SQL statements (SELECT, INSERT, UPDATE, etc...)
inside an application (e.g. Java application, VB application, etc...),
do we consider those SQL statements as static SQL? or embedded SQL?
How about dynamic SQL? any practical examples?
Please advise. thanks!!
dear experts,
i heard in a session, that the tables which are modifying continuously are known as dynamic tables.and which are not are known as static tables.
my question is how to find the statics to judge static and dynamic tables?
Hi All,
We're currently preparing for a project for a bank client of ours where we would be using SQL Server 2008's data mining capabilities.
In the context of the out-of-the-box algorithms of SQL08 does the algorithms Logistics, Clustering and Logistic Regression includes Dynamic Logistics, Dynamic Clustering and Dynamic Logistic Regression?

Joseph
I have gotten mixed comments on this topic. I have a 64 bit machine running 64 windows 2003 standard and 64 SQL 2005 standard with 8 GB of RAM. We want to upgrade it to 32 GB. What is the best approach to do this? Dynamic or Stattic giving min and max server memory a value ? and if static what value should I use for 32 GB knowing that this box is only being used for SQL.

View 3 Replies View RelatedIn one step of an SSIS package, i create an outgoing XLS filename based on the current datetime setting, a la:
"myFileName_" + (DT_WSTR,4)YEAR( getdate()) + RIGHT("0" + (DT_WSTR,2)MONTH( getdate()),2)+
RIGHT("0" + (DT_WSTR,2)DAY( getdate()),2) +
RIGHT("0" + (DT_WSTR,2)DATEPART("hh", getdate()),2) +
RIGHT("0" + (DT_WSTR,2)DATEPART("mi", getdate()),2) +
RIGHT("0" + (DT_WSTR,2)DATEPART("ss", getdate()),2) +".xls"
which provides the format as myFileName_yyyymmddhhmmss.xls.
This value is then assigned to a variable, user::myFilenameDateTime.
This variable is referred to in various steps which need the full pathname or filename.
I found, though, that in subsequent steps, the value for user::myFilenameDateTime is re-calculated whenever the variable is invoked.
So in one Task i created the physical output XLS file and named it "correctly", eg, myFileName_20070428090204.xls; in the next Task, i call a Stored Procedure in SQL Server 2005 to email the file with a corresponding message (that pulls in more data from the database).
The single Parameter to the Stored Procedure (that does the emailing) is the supposed/expected full Pathname of the outgoing file just produced but the parameter no longer represents the original filename -- and has changed slightly (a few seconds have been added) and the filename is now, myFileName_20070428090210.xls; consequently, my Email Distribution program cannot find the file with that specific name, although File = myFilename_20070428090204.xls does certainly exist.
so it appears that these variables are calculated realtime whenever encountered.
1) Am I misunderstanding something or misusing the variable assignment?
2) How can i keep << myFileName_yyyymmddhhmmss.xls >>, "static" throughout the duration of the overal SSIS Process.
3) I would think that even if I assign the derived myFileName value initially to ANOTHER "static" variable, this won't achieve anything because the new variable will be re-calculated again, as well, when it is invoked.

Hi every one,
Could you please anyone tell me how to have static and dynamic columns in a matrix?
We can add static columns by right clicking detail text box and add column. But it will repeat for each column group. I need static columns in the dynamic columns level itself.
Thanks in advance!
I need to put a dynamic table (the amount of rows I control) into a static container (with a fixed size).
View 2 Replies View RelatedI'm trying to setup a dynamic ole db connection using the SA user ID, it has to be dynamic because the server name will change and it has to be SA because we're pulling information from system databases that some users don't have access to.
If I setup a regular static connection using SA credentials it works like a charm of course. When I create an expression to use the User:erver variable it doesn't work, it throws an error message saying that "The login failed for user sa" among other things, I'm thiking that the sa's password is not being saved.
Where exactly do I place a password for dynamic connections using sql server users? On the connection string? On the password property of the source? Any ideas?
I'm using Delphi 2006 to create a DLL which will be integrated into SQL 2005. It's been a long road and I've made a lot of headway, however I am currently having the following problem creating the stored procedure:
My dll name is 'Crystal_Reports_Test_01'
In the DLL, my class is named 'Class01'.
In the DLL, my procedure is named 'TestMe'
I've managed to integrate the DLL into SQL using the following statement:
CREATE ASSEMBLY TEST_ERIC_01
AUTHORIZATION dbo
FROM 'c:mssqlassembliescrystalreports.dll'
WITH PERMISSION_SET = UNSAFE
I am attempting to create the stored procedure which points to the 'TestMe' method inside of the DLL. FYI: 'CrystalReports' is the namespace above my class that I had to add in order to get it to locate the class. The following code is used to create the stored procedure:
create procedure dbo.Crystal_Reports_Test_01(
@Parm1 nvarchar(255)
)
as external name TEST_ERIC_01.[CrystalReports.Class01].TestMe
But I get the following error:
Msg 6573, Level 16, State 1, Procedure Crystal_Reports_Test_01, Line 1Method, property or field 'TestMe' of class 'CrystalReports.Class01' in assembly 'CrystalReports' is not static.
I'm not sure what this means exactly. I think it means the method (the procedure) is not using Static method binding but should be. I have no idea what this really means or how to accomplish this in the DLL - or if I'm even going about this in the right way.
Any help would be appreciated ! I'll post the Delphi code (DLL) below.
Thanks,
Eric Gooden
library CrystalReports;uses System.Reflection, System.Runtime.InteropServices;...................type Class01 = class public procedure TestMe([MarshalAs(UnmanagedType.LPWStr)] var sVarString: wideString); export; end;procedure Class01.TestMe([MarshalAs(UnmanagedType.LPWStr)] var sVarString: wideString); export;begin sVarString:= 'Lets change the value and see if the stored proc. gets the change.';end;end.
I have some data in Excel - sheet1 which would be static.
Now I need to import data from SQL Server (using a query) and Union above static data with this SQL data and later I will have to create PowerPivot table in Sheet2.
Which is suitable option for me to import data from SQL to excel as I see "From SQL Server" option under "Data" and "Power Query" tab as well.
How to merge above SQL data with existing static data?

I have a DTS package that transfers some columns defined as varchar(8000).
Sometimes, the values in the columns defined this way have embedded CR/LF in them. When they do, DTS does not always transfer the values to the target.
Any idea why? Workarounds? TIA.
I have the following stored procedure...
CREATE Procedure UserGetInfo2 (@UserID int, @SystemTimePeriodID int )As set nocount onSELECT Users.UserId as UserID, Users.UserName as UserName, Users.RealName as RealName, UserTimePeriod.BudgetCode as BudgetCode, UserTimePeriod.SystemTimePeriodID as SystemTimePeriodID, Users.Password as Password, Users.SSN as SSN, Users.Location as Location, Users.ScheduleType as ScheduleType, Users.EmployeeType as EmployeeType, Users.TimeAccounted as TimeAccountedFROM Users INNER JOIN UserTimePeriod ON Users.UserId = UserTimePeriod.UserIDWHERE (users.userID= @UserID) AND (UserTimePeriod.SystemTimePeriodID = @SystemTimePeriodID)returnGO
The problem lies in that when a person has a SystemTimePeriodID over a certain value, there is no UserTimePeriod record since it has not been created yet.
Obviously, I need to wrap this in an IF...EXISTS
IF EXISTS (SELECT UserTimePeriodID FROM UserTimePeriod WHERE (SystemTimePeriodID = @SystemTimePeriodID) AND (UserID = @UserID))
(the SELECT above, since that's what needs to come back if the data exists)
ELSE
Do the same select but put in a static value for BudgetCode, like '0000'
GO
How could I do the part where the IF...EXISTS fails?
I'm... not sure I can use RETURNS, since it feeds into this recordset:
rstUserInfo2.Open "UserGetInfo2 " & Request("UserID") & ", " & Request("SYSTIMEPERIODID")
and later uses values from that RecordSet, such as <td><%=rstUserInfo("BudgetCode") & ""%></td>

Why is using an embedded SELECT statement faster than using an embedded UDF that has the same exact SQL code within?
Example (not syntax corrected)
Ex1:
SELECT myValue1, myValue2 FROM myTable WHERE aValue = (SELECT Value FROM someTable WHERE myIndex = 800)
is much faster than something like
Ex2:
SELECT myValue1, myValue2 FROM myTable WHERE aValue = (dbo.FN_myUDF(@vmyIndex))
Given that dbo.FN_myUDF has the same code as the embedded select in the first example.
TIA,

I'm looking into a problem a friend is having, and I'll say right offthe bat that I work with with php and MySQL, and not MS SQL.What he is attempting to do (in MS SQL) is take two database fieldsfrom a table (string fields), multiply them together, and put them intoa third field. This third column in the table has not yet been createdthe time of running the query.If it needs to be multiple queries, that is fine. My first thought isto use a simple ALTER query to add the column to the table, then tocall a UPDATE function which uses a select statement inside of it. I'mnot sure if something like this can even be done.// ------------ Suggested queryUPDATE chrisslu SET 'discquantity' = '(SELECTchrisslu.quantity*chrisslu.nr_of_discFROM chrissluWHERE (str(period,6)>=? AND str(period,6)<=?))' WHERE(str(period,6)>=?Andstr(period,6)<=?)// ------------ End Suggested queryIt starts with an UPDATE, but replaces the value to be set with aSELECT statement. I honestly don't even think this query issyntactically correct, I'm just trying to get the general concept down:).So, question the first: Is this type of query possible? The reasonI'm doing this is because I was told MS SQL has no way of storingtemporary variables... otherwise I would just call a SELECT statement,store the variable, and UPDATE the new field from the variable afterthe ALTER statement.Second question: If it is possible, am I on the right track, or doesit need to be entered in completely different than what I have?Third: Regarding the 'type'. Do I need to do any kind of typecastingor conversion of the fields? Both chrisslu.quantity andchrisslu.nr_of_disc are string fields (that is what I was told, theymay be varchar of some kind). In order to use them in a mathstatement, do they have to be floats, or doubles, or something similar?I appreciate any response, I know this was a long winded question.Chris

Hi there!
I've an embedded image (logo) in my report, and in the preview it looks wonderful, but after deploy the logo doesnt appear in the report (report server).
The url of the dead-link-image is http://hamsql1/Reports$BI/Reserved.ReportViewerWebControl.axd?.
I thought that an embedded image is stored "in" the report, but it seems to be an other place. Is it nessecary to deploy an embedded image too? Is it a problem of permissions (i read it in another threat)? How to set these image-see-permission? Or is there an other problem?
Every idea is very welcome!

i have input and output tables
i will have to use input table to read data and then in procedure update/insert into output table ) insert values from input and dditioanl calulate charges.
ok, there is my problem:
An Internet service provider has three different subscription
packages for its customers:
Package A: For $15 per month with 50 hours of access provided.
Additional hours are $2.00 per hour over 50 hours.
Assume usage is recorded in one-hour increments,
i.e., a 25-minute session is recorded as one hour.
Package B: For $20 per month with 100 hours of access provided.
Additional hours are $1.50 per hour over 100 hours.
Package C: For $25 per month with 150 hours access is provided.
Additional hours are $1.00 per hour over 150 hours
Assume a 30-day billing cycle.
1) Create a table to hold customer input billing data.
2) Populate input table with follwing records:
CustomerID Pkg Hours
---------- --- ------
1000 A 49
1010 A 50
1020 a 90
1030 a 130
1090 B 40

1140 C 45
1150 c 85
1160 c 149
1170 c 150
1180 c 200
3) Create a table to hold customer data used to generate
the statement to be sent to the customer. It should
include CustomerID, Package, HoursUsed, and Charges.
Write an SQL script that reads customer billing data,
calculates a customer’s monthly charges, and populates
the customer statement table.
Use Cursor to process records and Stored Procedures for
ProcessBill and calcCharges.

What you mean by static group in matrix?
View 2 Replies View RelatedThis seems like it should be extremely obvious. I don't know if I'm just going insane or what...
If I add a matrix to my report and then right click a "data cell", I can add columns and rows. I go ahead and add however many columns and rows I want. Now I want to delete one of the rows I just added, how do I do that?
I have tried highling the entire row, but it doesn't allow me to delete it. If I select just one cell and click delete, it deletes the column and not the row. I can just use the "undo" command right after I create it, but if I have already done numerous other things to the report, it removes all of that first.
I must be missing something very obvious here.
Hello,
I have a dll which is developed in C#. I have made a reference to it from Reporting Services under Report Properties.
My problem is, that the methods in this dll are not static. Therefore under the Classes in Report Properties I have written the class-name and the instance-names of the instances that I need to use from this class (as I understand it, this is what you have to do if using non-static methods). In a text-box, I call one of the instances in the class, but I get this error:
[rsInvalidName] 'MyMethod()' is not a valid code class name. Names of objects must be CLS-compliant identifiers.
What exactly have I done wrong here?
Thanks

Hi,
I have a data; descriptions (types of elements in my system) on rows, and results (numeric values) of different branches for each description on columns. I have one entry (one row) for each individual day (so i have year, month and day columns) I prepared a report for this data (using enable drilldown; year --> month --> day --> description and its numeric values on the row) But I have to add new descriptions using my own descriptions, like formulas... My descriptions and my new descriptions made of with old ones, should be listed one under the other
For ex;
new_description = (descr1 + descr2) / descr7
Can I do this on report design step? If so, how?
Hi!
I have a function that uses a constant value on its calculations. This value is defined on a table. I don't want to query this table everytime I call the function (I call it on a loop from my Java code). Is there anything like a static variable I could use?
Thank you!
I have a Select statement that was working just fine:
string sSqlCmd = "INSERT INTO SiloKeywords (Silo_ID, Keyword, UserName) SELECT Silo_ID,'" + Keyword + "', '" + strUsername + "' FROM SiloNames WHERE Silo_Name = '" + Uri + "'";
the PM now wants to capture the internal User, which I have done but I am having real problems with the syntax if the internal User exists:
string sSqlCmd = "INSERT INTO SiloKeywords (Silo_ID, Keyword, UserName, IsInternal) SELECT Silo_ID,'" + Keyword + "', '" + strUserName + "', if EXISTS(SELECT * FROM InternalUsersList WHERE Alias = '" + arrResult[1] + "') 1 ELSE 0 FROM SiloNames WHERE Silo_Name = '" + Uri + "'";
I am completely lost here.
Thanks for any help
