We are working on C++ in eVC++ 3.0 environment (CE 3.0) with SQL CE 2.0.
We are trying with IRowsetIndex:: Seek method to access the data from the database.
We are facing problem when we try to access data from the table having composite index other than the first column.
For example:
The table ITEM contains the following columns:
1. ItemCode
2. PcNo
3. SubPcNo
4. BrandNo
5. DescText
6. ProductionKind
7. ProductionState
8. ClearingState
9. ST
10. TS
I€™ve two indexes for this table where the two indexes are
1. ItemKey1 on ITEM (ItemCode).
2. ItemKey2 on ITEM (PcNo, SubPcNo, BrandNo).
If I mention ItemKey1 as the index then the Seek method works perfectly.
But if I mention ItemKey2 as the index, then I€™m getting the error as €œDB_E_BADBINDINFO€?.
When we visted the MSDN for this problem we noted that:
1. When you use the Seek method on multiple fields, the Seek fields must be in the same order as the fields in the underlying table. If they are not, the Seek method fails.
2. When passing key values to an index rowset, the consumer performs these actions only for the number of key columns specified in the cKeyValues argument in IRowsetIndex:: Seek.
So we had the composite index such that columns of a composite index are physically aligned next to each other as in the table.
When the first column of the index is the first column of the table as in index ItemKey1 we found that the seek method works perfectly.
If we pass the index ItemKey2, we are again getting the error €œDB_E_BADBINDINFO€?.
What else have we missed out while passing the keys in IRowsetIndex:: Seek?
I know passing table/column name as parameter to a stored procedure isnot good practice, but sometimes I need to do that occasionally. Iknow there's a way can do that but forget how. Can someone refresh mymemory?Thanks.Saiyou
Hello everyone, I am new to ERWIN and I need helps from the experts outthere.We are using ERWin 4.1.2771 and have reversed engineered some MS SQLServer 2000 databases.The problem we are having is that we have a FK on a column to a tablewhere the PK of the referencing table is on another column (such as anidentity column). We have a unique index on the column in the PK tableand SQL Server allows you to build a FK reference even though thecolumn is not defined as the PK.Does anyone know how to create this type of FK within Erwin?Thank You
I'm running 2014 enterprise and getting an error on this form of a query...it says the multi part identifier "mns.col3" could not be bound. I'm aware that a cross apply would be more appropriate but i'm just prototyping and probably going to move to a set based approach anyway.The udf returns a table.
select mns.col1, mns.col2 from table1 mns left join dbo.udf_udf1(@firstofmonth,@lastofmonth, mns.col3) x on 1=1
I have a table with an Identity Column set up. I also have an index on the table that is set to Ignore Duplicate. Identity starts at 1 and is incremented by 1.
So first 5 rows inserted get identity
1
2
3
4
5
If I insert rows that get ignored because of the index with Ignore Duplicate, it is ignored correctly. But, the next row to get inserted will have an identity value of 7.
So, even though the insert was ignored because of the index with Ignore Duplicate, the Identity column was incremented behind the scenes.
I have created NONCLUSTERED index on table but my report is taking more time that's why i created columnstore NONCLUSTERED index on the same table but i have one query, if any table have row and column level index(same columns in index) . Which index query will consider.
I am trying to create a sample table in the Azure SQL  Data warehouse but its giving me a syntax error Incorrect syntax near the keyword 'CLUSTERED'.
CREATE TABLE [dbo].[FactInternetSales] ( [ProductKey] int NOT NULL , [OrderDateKey] int NOT NULL , [CustomerKey] int NOT NULL , [PromotionKey] int NOT NULL
Web Base application or PDA devices use to initiate the order from all over the country. The issue is this table is not Partioned but good HP with 30 GB RAM is installed. this is main table that receive 18,0000 hits or more. All brokers and users are using this table to see the status of their order.
The always search by OrderID, or ClientID or order_SubNo, or enter any two like (Client_ID+Order_Sub_ID) or any combination.
Query takes to much time when ever server receive more querys. some orther indexes are also created on the same table like (OrderDate, OrdCreate Date and Status)
My Question are:-
Q1. IF Person "A" query to DB on Client_ID, then what Index will use ? (If any one do Query on any two combination like Client_ID+Order_ID, So what index will be uesd.? How does MS-SQL SERVER deal with these kind of issues.?
Q2. If i create 3 more indexes on ClientID, ORderID and OrdersubID. will this improve the performance of query.if person "A" search record on orderNo so what index will be used. (Mind it their would be 3 seprate indexes for Each PK columns) and composite-Clustered index is also available.?
Q3. I want to check what indexes has been used? on what search?
Q4. How can i check what table was populated when, or last date of update (DML)?
My Limitation is i Dont Create a Partioned table. I dont have permission to do it.
In Teradata we had more than 4 tb record of CRM data with no issue. i am not new baby in db line but not expert in sql server 2003.
I'm running a merge replication on a sql2k machine to 6 sql2k subscribers. Since a few day's only one of the merge agents fail's with the following error:
The merge process could not retrieve generation information at the 'Subscriber'. The index entry for row ID was not found in index ID 3, of table 357576312, in database 'PBB006'.
All DBCC CHECKDB command's return 0 errors :confused: I'm not sure if the table that's referred to in the message is on the distribution side or the subscribers side? A select * from sysobjects where id=357576312 gives different results on both sides . .
Hi everyone, When we create a clustered index firstly, and then is it advantageous to create another index which is nonclustered ?? In my opinion, yes it is. Because, since we use clustered index first, our rows are sorted and so while using nonclustered index on this data file, finding adress of the record on this sorted data is really easier than finding adress of the record on unsorted data, is not it ??
Hi,Would like to know the performance differenece between Multi-columnIndex vs Single Column Indexes. Let's say I have a table with col1,col2, col3 along with a primary key column and non-indexed columns.In queries, I will use col1, col2, and col3 together and some timesjust one or two of these three columns. My questions is, should Icreate one index contains col1, col2, and col3, or create 3 seperatedcolumns. I.e. each column has its own index. Any performancedifference?Thanks a lot.
When I was but a young developer, I saw many databases that made use of XREF columns to manage the revision history of records; if a customer had a change of name, a new customer record was created with the new name and the old record was given a cross reference to the new record. Often the user was also required to enter a reason for the cross reference.
This was a very practical paradigm, easily understood by users as it mirrored business practices that were followed regarding paper records. It presented some issues for reporting however, as following xref chains did not translate easily into set based grammars.
Fast forward to the modern times. The prevalent approach has been the use of effective dating and transactional dating, which -- while possibly superior from an algebraic standpoint -- has its own drawbacks in application.
One weakness is the lack of a paradigm or strong metaphor. This often leads to imperfect implementations where data entry errors cannot be distinguished from more meaningful changes, or historical reporting that presents incorrect information because of the multiplicity of dates.
In addition, of particular interest is that often no facilities exist in modern systems to handle real world situations involving duplicate records: a customer is entered into a system, changes names, and is entered into the system again under the new name. The error is discovered some time later, after invoices or statements may have been sent to both customer records, but no function exists within the system to indicate that both records refer to the same entity. It becomes an issue for DBAs to deal with and resolve.
I would be interested to hear any comments or rebuttals from individuals as to which technique they feel is superior, and additional weaknesses or strengths of the two techniques.
I need to select status values form 1 of 4 possible columns, and I need topass the column name to select on as a parameter to the stored procedure.Does anyone have an example of the syntax for the stored procedure?such as:CREATE PROCEDURE dbo.sp_Document_Select_ByStatus(@SelectColumn nVarChar)ASSET NOCOUNT ON;SELECT *FROM DocumentsWHERE (@SelectColumn = 0)The columns to select on are BIT columns.The error message on the above SP is:'Syntax error converting the nvarchar value 'P' to a column of data typeint.'At this point, the passed in parameter is a string "ProducerStatus"ThanksMichael
I would like to know on how to pass a column name into a particular variable.
Example Table_name    Column_name Tablenm       Name Tablenm       Age Tablenm       Phone
The output will be:
ColName     Value Name       Alexander Grahambell Age         32 Phone       123456 Name       Sanosuke Sagara Age         35 Phone       246790
I'm writing a simple voting script and have columns for each options. I need to update the data based on whichever option the user picks.I.e...If the user picks option 1 then execute UPDATE mytable SET option1 = option1 + 1If the user picks option 2 then execute UPDATE mytable SET option2 = option2 + 1 Etc., etc.What's the best way to do that without building an ad-hoc SQL statement? There could be many options so I dont want to have lots of redundant SQL statements.Can I just use a varible in a stored proc and do something like this? UPDATE mytable SET @optionUserpicked=@optionUserpicked + 1Thanks in advance
HII m trying to use the following Store Procedure to search Suppliers... user provides a Column Name (Search By) and an Expression... but i m not getting it work properly... plz review it and tell me wots wrong with this stored procedure is...

Is there a way to pass the column name as a query parameter?? If I use '@Question', like below, I get an error. If I change it to the actual name of the column 'Question1', it works fine. However, I need it to be dynamic so I can pass the column name [Question1, Question2, Question3, etc...] in and not have to define this for each question.
Doesn't Work!!
Code:
SELECT
1.0 * SUM(CASE WHEN @ColumnName > 1 THEN 1 ELSE 0 END) / COUNT(*) AS 'Good', 1.0 * SUM(CASE WHEN @ColumnName = 0 THEN 1 ELSE 0 END)/ COUNT(*) AS 'OK', 1.0 * SUM(CASE WHEN @ColumnName < 0 THEN 1 ELSE 0 END) / COUNT(*) AS 'Poor'
FROM tableA AS A INNER JOIN tableB AS B ON A.SessionID = B.SessionID
WHERE (A.SurveyID = @SurveyID) AND (A.SubmitDate BETWEEN @BeginDate AND @EndDate)
Works, but I need to pass in the column name dynamically.
Code:
SELECT
1.0 * SUM(CASE WHEN Question1 > 1 THEN 1 ELSE 0 END) / COUNT(*) AS 'Good', 1.0 * SUM(CASE WHEN Question1 = 0 THEN 1 ELSE 0 END)/ COUNT(*) AS 'OK', 1.0 * SUM(CASE WHEN Question1 < 0 THEN 1 ELSE 0 END) / COUNT(*) AS 'Poor'
FROM tableA AS A INNER JOIN tableB AS B ON A.SessionID = B.SessionID
WHERE (A.SurveyID = @SurveyID) AND (A.SubmitDate BETWEEN @BeginDate AND @EndDate)
Hello, I'm quite new to T-SQL, but since I'm trying to create a statistics page on database contents (Counting savesets in Enterprise Vault saveset Databases) I prefer to do the coding in the databases. I create temp tables for the distinct partitions in the saveset table. Then I pass 2 variables to the EXEC function, but it seems unable to pass the ['+@idpartition+']-variable as a value: Declare @EVBase varchar(20)Declare @IdPartition INTSet @EVBase=(SELECT EVMbxName from Servers) Set @IdPartition=(SELECT TOP 1 Dist_Partitions FROM TEMP_EV1)EXEC('SELECT COUNT (IdPartition)FROM ['+@evbase+']..SAVESET SS LEFT OUTER JOIN SavesetStore SSS ON SS.SavesetIdentity = SSS.SavesetIdentityWHERE [IdPartition] = ['+@idpartition+'] AND StoreIdentifier IS NULL') Server: Msg 207, Level 16, State 3, Line 2Invalid column name '0'. If I change the last line to: WHERE [IdPartition] = 2 AND StoreIdentifier IS NULL')The script runs fine - but I need the value from the table. Any help will be appreciated. Best regards, Tim

Hi!I want to pass a column name, sometimes a table name, to a storedprocedure, but it didn't work. I tried to define the data type aschar, vachar, nchar, text, but the result were same. Any one know howto get it work?Thanks a lot!!Saiyou
I am trying to pass a variable set by a Row count transformation to a derived column transformation. There are actually three separate Row Count transformations storing to different variables. In the derived column trans. the expression i am using is @[User::ClientCount] and the variable type is Int32 and I am passing it to an I4 database column. After the derived column trans. all rows just come out with 0s in the row count columns. Does anyone know why this would be? Please let me know if you need more information.
Hello, It is possible to write stored procedures which take table names as parameters; is it also possible to do this with table valued functions?
For example, a simple stored procedure is this:
CREATE PROCEDURE SelectTop(@tableName sysname) AS BEGIN
Execute('Select top 10 * from ' + @tableName + ';')
END
I want to be able to do the analogous thing with a table valued function (so that I can query the result set, without having to create a temp table). How should I do this (i.e., pass a tablename as an argument to a table valued function)?
After several hours of trying, I trow the towel in the ring and come here to ask a question.
Source system uses a timestamp column in the transaction tables. which is equal to a non-nullable binary(8) datatype (sql 2000 bol).
What I want to do is get the timestamp at the start of the transfer and at the end of the transfer of data. and store these in a controltable
I try to do this in 2 sql execute tasks:
sqltask 1: "select @@DBTS AS SourceTimestamp" and map the resultset to a variable. Here come's the first problem what variable type to take ?
DBNULL works (meaning it doesn't give errors) (BTW: is there a way to put a variable as a watch when debugging sql tasks ?)
INT64 and UINT64 don't work error message that types for column and parameter are different
STRING works
Then I want to store this variable back in a table of a different data source
sqltask2: "insert into controltable values(getdate(), ?)" and make an input parameter that takes the previous timestamp ...
if I took DBNULL as a type for the variable there doesn't seem to be a single parameter type that works ???
if i take STRING as a type for the variable I have to modify the sql to do the explicit conversion from string to binary so I change CAST(? as binary). It doesn't return any error but the value stored in the table is 0x00000000000 and not the actual timestamp.
Any help on this one ? Why are the INT64/Bigint not working here, you can perfectly do a convert(bigint, timestampfield) in sql ?
How came the SQL datatypes, and the variable datatypes, parameter datatypes are so badly alligned to each other (and all seem to use different names) ?
I am building a generic SSIS where it takes a text source file and converts to a destination source file . However in the process I want to set the row delimiter and the column delimiter dynamically through the package variable. So that I can use it for any file transfer.
I saw the option for row delimiter in the file connection string property but did not see any column delimiter option.
I have the following in my table. As you can see the Geo field is null (which is of type Geography), what I'm trying to do is populate that with an update statement by comparing the latitude and longitude for each row so I can then work out the distance, I've been following this tutorial to workout the distance which is giving me the desired results
[URL] ....
The issue I have is passing in the points i.e latitude and longitude and then updating the Geo field for the row, I currently have 11938 rows in my DB so I need to run this against all of them. I thought I had it I was thinking of update then select from the source but then I realized I need to pass the lat and long in for the points and that's where I got confused
MSSql2000: According to docs: "Columns of type bit cannot have indexes on them"
Its impossible to define index on bit column using EM but ‘create index …’ command in QA is working and the index is created. I understand why not to create index like this but … its valid or invalid operation to create index on BIT column ?
