Memory Issue With Simple CLR Based Table-Value-Function (TVF)
Dec 15, 2005
Hi,
We are seeing memory issues with a simple C# based TVF that splits an input string into a table based a delimiter. Entries such as the following show up in the SQL log:
AppDomain 8 (DBName.dbo[runtime].7) is marked for unload due to memory pressure.
AppDomain 8 (DBName.dbo[runtime].7) unloaded.
These entries only show up after the TVF has been called many times (~ half million times or more).
We encountered the same memory issues with June CTP, but they appeared to be fixed in Sepetmber CTP. Somehow the issues come back for us in the SQL Server 2005 RTM version. With June CTP after these errors show up many many times, the SQL server had to be re-started.
I'd appreciate any comments/ideas regarding these error messages in the SQL log?
We are using the RTM version of SQL2005: Microsoft SQL Server 2005 - 9.00.1399.06 (Intel X86)

Hi~, I have 3 questions about memory based bulk copy.
1. What is the limitation count of IRowsetFastLoad::InsertRow() method before IRowsetFastLoad::Commit(true)?
For example, how much insert row at below sample?(the max value of nCount)
for(i=0 ; i<nCount ; i++)
{
pIFastLoad->InsertRow(hAccessor, (void*)(&BulkData));
}
2. In above code sample, isn't there method of inserting prepared array at once directly(BulkData array, not for loop)
3. In OLE DB memory based bulk copy, what is the equivalent of below's T-SQL bulk copy option ?
BULK INSERT database_name.schema_name.table_name FROM 'data_file' WITH (ROWS_PER_BATCH = rows_per_batch, TABLOCK);
-------------------------------------------------------
My solution is like this. Is it correct?
// CoCreateInstance(...);
// Data source
// Create session
m_TableID.uName.pwszName = m_wszTableName;
m_TableID.eKind = DBKIND_NAME;
DBPROP rgProps[1];
DBPROPSET PropSet[1];
rgProps[0].dwOptions = DBPROPOPTIONS_REQUIRED;
rgProps[0].colid = DB_NULLID;
rgProps[0].vValue.vt = VT_BSTR;
rgProps[0].dwPropertyID = SSPROP_FASTLOADOPTIONS;
rgProps[0].vValue.bstrVal = L"ROWS_PER_BATCH = 10000,TABLOCK";
PropSet[0].rgProperties = rgProps;
PropSet[0].cProperties = 1;
PropSet[0].guidPropertySet = DBPROPSET_SQLSERVERROWSET;
if(m_pIOpenRowset)
{
if(FAILED(m_pIOpenRowset->OpenRowset(NULL,&m_TableID,NULL,IID_IRowsetFastLoad,1,PropSet,(LPUNKNOWN*)&m_pIRowsetFastLoad)))
{
return FALSE;
}
}
else
{
return FALSE;
}

I want my query to list all SSNS that have more than one record in the table. I have this query:
Code:
SELECT SSN, name4, count(*) from [1099_PER]
group by SSN, name4
having count(SSN) > 1
It does retrieve the right SSNS and tells me how many times the SSN occurs in the table. However, I want my query results to display their full records.
For example
SSN NAME4 COUNT
123445555 WALTER - 4
I want the query to show me all four records for this SSN. I thought removing the count field would do this, but it still gives me only one instance of each SSN.

Hey,First, sorry if this post appear twice, because, I can not find my postrecently send, trying to post it once again.I'm out of ideas, so, I thought, will search help here again :(I'm trying to prepare a view for ext. app. This is in normal cases veryeasy, but what if the view structure should be dynamic?!Here is my point (I will siplify the examples).I have a table:create table t_data (id bigint identity (1,1) not null,valvarchar(10) not null,data varchar(100) not nullconstraint [PK_t_data] primary key clustered(id) with fillfactor = 90 on [PRIMARY] )goinsert into t_data (val, data) values('1111111111','1234567890abcdefghijklmnoprstuvwxyz 1234567890abcdefghijklmnoprstuvwxyz67890abcdefghij klmnoprstuvwxyz')insert into t_data (val, data) values('2222222222','1234567890abcdefghijklmnoprstuvwxyz 1234567890abcdefghijklmnoprstuvwxyz12345abcdefghij klmnoprstuvwxyz')insert into t_data (val, data) values('3333333333','12345abcdefghijklmnoprstuvwxyz12345 67890abcdefghijklmnoprstuvwxyz1234567890abcdefghij klmnoprstuvwxyz')insert into t_data (val, data) values('4444444444','67890abcdefghijklmnoprstuvwxyz12345 67890abcdefg12345hijklmnoprstuvwxyz67890abcdefghij klmnoprstuvwxyz')insert into t_data (val, data) values('5555555555','1230abcdefghijklmnoprst12345uvwxyz1 234567890abcdefghijklmnoprstuvwxyz67890abcdefghijk lmnoprstuvwxyz')gocreate table t_dataVal (id bigint identity (1,1) not null,valvarchar(10) not null,fill varchar(4) not nullconstraint [PK_t_dataVal] primary key clustered(id) with fillfactor = 90 on [PRIMARY] )goinsert into t_dataVal (val, fill) values ('1111111111','AAAA')insert into t_dataVal (val, fill) values ('2222222222','KKKK')insert into t_dataVal (val, fill) values ('3333333333','DDDD')insert into t_dataVal (val, fill) values ('4444444444','ZZZZ')insert into t_dataVal (val, fill) values ('5555555555','CCCC')gocreate table t_conf (id bigint identity (1,1) not null,start int not null,length int not null,description varchar(20) not null,constraint [PK_t_conf] primary key clustered(id) with fillfactor = 90 on [PRIMARY] )goinsert into t_conf (start, length, description) values (1,10,'value_1')insert into t_conf (start, length, description) values (11,3,'value_2')insert into t_conf (start, length, description) values(55,15,'value_3')insert into t_conf (start, length, description) values (33,2,'value_4')insert into t_conf (start, length, description) values (88,1,'value_5')insert into t_conf (start, length, description) values (56,7,'value_6')goNow here is the issue:table t_conf contain data, which can be modified by user. The user isseting the appropriate values.Now, there should be a view, which returns:- as headers (collumn names) this what is defined in description columnof t_conf (for example: value_1, value_2 ... value_6)- as values, substrings of all data from t_data, cutted with start andlength values for appropriate decription from t_conf.- first two columns of view, should be column val and fill of t_dataValtableSo the effect should be like this:valfillvalue_1value_2value_3value_4value_5value61111111111AAAA1234567890abc....2222222222KKKK1234567890abc....3333333333DDDD12345abcdefgh....4444444444ZZZZ67890abcdefgh....5555555555CCCC1230abcdefghi....of course, for all other value_x should be the appropriate substringsshown.Sounds simple, hm?Well, I'm trying to do this, since yesterday evening, and can not :(In real life, the call of view/function might happend a lot.The table t_data might have around 4000 records, but the data string islonger (around 3000 characters).Application, might acess a udf, which returns table, and I was focusingin that.Was trying, to create local temp table in function, to insert values,using cursor over t_conf.Unfortunately, everything what I get, is just a vertical representationof the data, and I need it horizontal :(The other problem in function is, that I can not use exec() (wll known)so I can not even create a table,dynamicly, using as column names description value from table t_conf,and as size of field length from this table.Sorry, that the description is maybe not exactly for my problem, butthis is because I'm not even sure, which way to use :(any help will be appreciated!Thank You - Matik

I have a requirement regarding a color combination data. I have a lookup table that holds a colorid, p1, p2, p3, p4 to p8 which will be having colors Red, Green and Amber. P1 to P8 columns holds these three colors based on their combinations.
I have attached the look up table data for reference.I need to pass the color values to p1 to p8 and need to retrieve the color id based on the passed color. If we pass values for all p1 to p8 then it is easy to get the color code, however it will not happen. The passed values may be dynamic. ie we will not have all 8 values all the times. sometimes we will have 2 colors passed, sometimes 5 colors will be passed.
If i pass only two colors say red and red, i need the color id of only the row that has red and red for p1 and p2 alone. i dont want want all the colorid's that has red and red in p1 and p2 and some other colors in p3 to p4.
The exact colorid of the combination must be returned on passing the values to p1 and p2.I am passing Red and Red as values to P1 and P2. In the look up table we can have 10 rows that has red and red i p1 and p2 like
colorid p1p2p3p4p5p6p7p8
1 redred
10 redredred
20 redredred
30 redredredred
40 redredredredred
50 redredredredredred
60 redredredredredredred
70 redredredredredredredred
So the result must have only the colorid 1 and not all the colorid's listed above. when I pass 3 red as values for p1, p2, p3 then the result must be 10. Colorid 1, 20, 30, 40, 50, 60 and 70 must not come in the result.I need a function or procedure that will accept the arguments and provide me the result based on the values.

I am looking to test this feature - and the "Transaction Performance Collector" has recommended me a table to port to In-Memory OLTP.
I have now tried the "Table Memory Optimization Advisor" tool.
After a couple of tweaks to the table design - the tool is now passing validation but the tool is not allowing to progress to the next step:
Could it be down to not having enough memory? But would this not show in the advisor?

Hello all. I have an Access table with EmpName, JobTask, and Hours. Multiple lines can contain the same Employee with the same JobTask. What I need to do is to list the Employee, JobTasks (grouped), and summed hours for each JobTask.
DB Ex:
John Doe Welding 8
John Doe Cleaning 4
Bubba Smith Fork Lift 3
John Doe Welding 7
Steve Johnson Welding 5
Bubba Smith Fork Lift 6
Page output:
John Doe
Welding 15 hrs.
Cleaning 4 hrs.
Bubba Smith
Fork Lift 9 hrs.
Steve Johnson
Welding 5 hrs.
This is how I figured it should be, but it's not working for me:
SELECT EmpName, SUM (Hours), JobTask
FROM tblEmpTime
Group By JobTask
Any suggestions would be greatly appreciated.
Thanks,
Parallon

Hey all,
Very simple question from a real n00b: In many of my stored procedures I am repeating a CASE statement where I'm replacing null values with zero, like this:
(CASE WHEN @Field IS NULL THEN 0 ELSE @Field END)
I have many SPs where I have that code repeated literally dozens of times. Is there any performance benefit to creating a function to perform this task and using that instead of the repeated CASE statements? Or am I trying to be too clever?
Thanks!

Hi, I need to write a simple function to format the contents of the fields in my table. I bascially want to say that if the value in a field is below '0' then format the text in colour red and if the value in the field is 0 or above then format it in black. Obviously this can be done by writing an expression in each field but i would prefer to write a function - any ideas.....

Hi All,
Does anyone know how to return a date the sql query analyser like (Aug 2, 2004)
Right now, the following statement returns (Aug 2, 2004 8:40PM). This is now good because I need to do a specific date search that doesn't include the time.
Many thanks in advance!!

I have a really basic question. The following SQL query works for me:
Select EnterUserID, Enterdate
from tblCsEventReminders
where EnterDate >= Convert(datetime, '2015-04-01')
I am essentially trying to write a query to count the number of user logins after a certain date, so I need to count 'EnterUserID' but I am having problems getting the count() function to work.

I have created an assembly with permission set safe, and a function inside the assembly.
The function reads data from the same SQL Server as it is running inside. For connection I use the "Context connection = true", and the function has the SystemDataAccessKind attribute set to Read.
However when I execute my CLR function I get an error saying something like:
"The request for permission of type System.Data.SqlClient.SqlClientPermission...... failed"
I do, as the login user, have been granted the necessary rights, so I don't believe this is the answer to the error.
And my .dll is also signed.
Has this something to do with writing something a config file?
I have had simular problems with reporting services but fixed them by entering a node in the rspolicy.config file. If this is the case here - which .config file should i modify...machine.config?

Here is one such function:CREATE FUNCTION my_max_market_date () RETURNS datetimeBEGINDECLARE @mmmd AS datetime;SELECT max(h_market_date) INTO @mmmd FROM holdings_tmp;RETURN @mmmd;ENDOne change I had to make, relative to what I had working in MySQL, wasto insert 'AS' between my variable and its type. Without 'AS', MS SQLinsisted in telling me that datetime is not valid for a cursor; and Iam not using a cursor here. The purpose of this function is tosimplify a number of SQL statements that depend on obtaining the mostrecent datetime value in column h_market_date in the holdings_tmptable.The present problem is that MS SQL doesn't seem to want to allow me toplace that value in my variable '@mmmd'. I could do this easily inMySQL. Why is MS SQL giving me grief over something that should be sosimple. I have not yet found anything in the documentation for SELECTthat could explain what's wrong here. :-(Any ideas?ThanksTed

We were asked to create an SQL function to return a unit price based on various criteria. The function works fine except for the tiered pricing (use of BillingPriceTable) calculation. What we need to do is break up the total quantity passed to the function and return the total of prices found. In our example, we passed a quantity of 9,721 units and need to return a total price of 231.92 using the table below.
Low Qty High Qty Fee Actual Qty Price
0 7500 0.025 7500 187.50
7501 15000 0.020 2221 44.42
Below is the table definition that we have to work with (ugghh).
CREATE TABLE [dbo].[BillingPriceTable](
[PriceTableID] [int] IDENTITY(1,1) NOT NULL,
[entity] [varchar](4) NULL,
[PriceTableCode] [varchar](10) NULL,
[PriceTableName] [varchar](40) NULL,
[Code] ....
What we have so far is shown below. The columns that start with bdxx are the "High Qty" values and the columns that start with prxx are the price for that quantity range. So, the current SELECT is shown below and it returns the price based on the entire qty of 9,721 and returns a unit price of 0.020 and should return 0.023857628
The current SELECT is shown below and is returning 0.020 which is the fee for the total rather than calculating the fee twice, once for the 0-7500 and again for the 7501-15000 (actually 7501-9721). Two things came to mind, one was a WHILE loop and the other was possibly a ranking function of some sort.
ALTER FUNCTION [dbo].[fn_GetPrice]
(
@plincdvarchar(3),
@pgrpcodevarchar(4),
@pitmcodevarchar(4),
@qtydecimal(10,1) = 1,
@corpnbrvarchar(9)
)
[Code] ....

I created a CLR function based on following VB code:
Imports Microsoft.SqlServer.Server
Public Partial Class SqlClrVB
<Microsoft.SqlServer.Server.SqlFunction()> _
Public Shared Function GetTotalPhysicalMemory() As Integer
GetTotalPhysicalMemory = My.Computer.Info.TotalPhysicalMemory
End Function
End Class
The VB code was complied into a DLL called totalmem.dll and call following TSQL to map it into a SQL function:
create assembly totalmem from '!WORKINGDIR! otalmem.dll'
WITH PERMISSION_SET=UNSAFE
go
create function fnGetTotalMem()
returns int
as external name totalmem.SqlClrVB.GetTotalPhysicalMemory
go
When I call this function, it returned following error:
select dbo.fnGetTotalMem()
Msg 6522, Level 16, State 2, Line 0
A .NET Framework error occurred during execution of user defined routine or aggregate 'fnGetTotalMem':
System.IO.FileNotFoundException: Could not load file or assembly 'System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.
System.IO.FileNotFoundException:

Anyone knows why I'm hitting this error? I didn't reference any System.Web interface why it needs to load System.Web assembly? The same code runs OK if I compile it as a separate VB application out side of SQL Server 2005.
Thanks much,

I’ve got a situation where the columns in a table we’re grabbing from a source database keep changing as we need more information from that database. As new columns are added to the source table, I would like to dynamically look for those new columns and add them to our local database’s schema if new ones exist. We’re dropping and creating our target db table each time right now based on a pre-defined known schema, but what we really want is to drop and recreate it based on a dynamic schema, and then import all of the records from the source table to ours.It looks like a starting point might be EXEC sp_columns_rowset 'tablename' and then creating some kind of dynamic SQL statement based on that. However, I'm hoping someone might have a resource that already handles this that they might be able to steer me towards.Sincerely,
Bryan Ax

I need to add a child table that will tell us who the participants counselor is, what I did was I did a Make Table query based off the primary key of the Parent table and made that the link (foreign key) for the People_tbl and the Counselor_tbl, so if the counselor changes then the user adds the record to the counselor tbl and then puts in the Effective date. The problem is that when I run a report it doesn't show the present counselor always shows the old counselor?
Code:
SELECT Student_ind.StudentFirstName, Student_ind.StudentLastName, Student_ind.[Student ID], People_tbl.[Family ID], People_tbl.FirstName,
People_tbl.LastName, People_tbl.[Parent ID]

I am working on a model where I have a sales fact table. Each fact record has four different customer fields (ship- to, sold-to, payer, and bill-to customer). I have one customer dimension table that joins to the sales fact table four times (once for each of the customer fields above). When viewing the data in Excel, I would like to have four hierarchies (ship -to, sold-to, payer, and bill-to customer) within Customer.
Is there a way to build hierarchies within my Customer dimension based on the same Customer table? What I want is to view the data in Excel and see the Customer dimension. Within Customer, I want four hierarchies.

Where EACH ROW(Except with Promotion ID ALL) Date Range Overlap with ROW(with promotion ID ALL) Date range
Note: ROW is Partition By ColumnA,ColumnB

Hello Friends,
I have two tables, And also I have Sample data in them.
create table X
(y int,
m int,
v int)
insert into X select 2007,1,5
insert into X select 2007,1,3
insert into X select 2007,2,9
insert into X select 2007,2,1
select * from X
Create table Y
(fy int,
fm int,
v int)
insert into Y select 2007,1,0
insert into Y select 2007,2,0
insert into Y select 2007,3,0
select * from X
select * from Y
I want to update the Table Y with the Sum of the Fields V from X based on the Criteria Y.fy = X.y and Y.fm = X.m
Using temporary table cannot be done.
Thanks in Advance,
Babz

over (PARTITION BY a.nif_antigo, r.novo ORDER BY a.nif_antigo)
from ACT_SECUNDARIAS a inner join
((select
[Code] ....
I want to make a delete statement like this:
select * into #table1 from actvidades_secundarias where rn>1
Delete from act_secundarias where act_secundarias.nif_antigo = #table1.nif_antigo and act_secundarias.cod_cae = #table1.cod_cae
But it seems that I cant delete like this.
