Please find below my queries, and help me to understand things..
1. How to find the port number of a specific SQLServer instance?(I have heard that the different instance of the SQLServer runs in different port number)
2. How to create a new instance for an existing SQLServer database? and how would i connect to it with my JDBC Connection string which usually reads as,
I am currently using SQL Server version 6.5 and am trying to execute the BCP command from the command prompt to update my database. Right now, if the tables doesn't have any primary key constraints, the BCP works fine and inserts all the rows to the database. Suppose the table has some primary keys and the datafile to the BCP has some duplicate records in it. It says, the following
Starting copy... Msg 2627, Level 14, State 1: Server 'DHRUVA', Line 1: Violation of PRIMARY KEY constraint 'PK_docket_booking4_1__10': Attempt to insert duplicate key in object 'docket_booking4'.
It does not insert any rows to the database. Is there anyway I can overcome this error and proceed on with the BCP to copy data. THe datafile which I give will have duplicate records.
i. If we have files and filegroups in place we have improved performance on backup and restore .Can we have any other improved perfortmance ? 2.If we are rebuilding or reorganising indexes on a table,which one will the degrades the performance more on the production server and which sits more on the transaction log. 3 how can we check the tableid in the database.
Hello i attended one interview . I have some doubts
1.) Indexes decreases the performance for insert ,UPDATE commands.? what will u do to increase the performance with these statements. 2.).tell me the 5 steps do u consider while writing a stored procedure to increase the performance.? 4).Is truncate a DDL or DML operation ? 5.) How to delete duplicate rows from a table? 6).table1 has an identity coluimn with 5 rows. delete opearation is performed on table 1.If user enters a new row what wiil be identity column no 1 or 6? table2 has an identity coluimn with 5 rows. truncate opearation is performed. .If user enters a new row what wiil be identity column no 1 or 6? 7.) when do we go for sub queries and when do we go for joins ? 8) could me tell the difference between sp and function.?
Hi, I am totally new to sql server and have got a few doubts.I couldnt find it in earlier posts.Sorry if it is a repetition
*Can we get all the table names of a database by Query? *How to create a similar copy of a table by using AS..does this work in sql server 2000?(tried but showing error) *can we modify the column properties(like ensuring NOT NULL) after the table is created?
I am having this question in my mind from when I started using SSIS.. In a package I have an OleDB source and a flat file destination. and I hook up the source to destination in SSIS and run the package.. it works .. fine.. but internally what is done??? does SSIS performs BCP out ???
set @DN=@DN+'AA9999' select @ID = ID from TableA where status='A' and ColumnA like '%'+@DN ColumnA is NonClusteredIndex
When I use = symbol it goes for Index Seek (like below query) otherwise its going for table scan. Could anyone advice me which index need to be used for getting 'Index Seek' when I use like Operator. Basically TableA has millions of records.
select @ID = ID from TableA where status='A' and Code = 'AA9999'
soon soon, í´ll have to devellop some procedures to read an ASCII file to supply MS SQL tables. As I´ve read some old post, I´ve understand that I have to use BULK INSERT , or else, BCP or DTS. I´d like to know the diference between this commands and witch of them is more powerful, faster and efficient. If you can give me some implementation tips, I will be very grateful.
hi, here i am inserting the total dates between 1983/08/26 to 2006/08/26. i.e the table will have 36525 recoeds approximately. after executing the command i verified the table n i noticed that the last record in this table was 2025/xx/xx approximately. why? defualtly what is the capacity of a sql table. can i change the table properties to hold more num. of records. please help me on this.

I've to do a mining project and I intend to use the SSIS.
I've done a clustering plugin last year on analysis services and I also want to use it.
Let me try to explain the architecture of the process:
1) Receive data (read data from the database - these data are texts, actually)
2) Pre-process the data (transform the texts in a sparse matrix) using a new plugin
3) Call my clustering plugin and assign it to read the table created on the previous step
4) Call my KNN plugin to classify other pre-processed texts using the clusters found on the previous step as classes.
5) Show results.
Alright... It all running as a workflow on integration services
Here are my doubts:
A) How to view and use my plugin made for Analysis Services on Integration Services ? (is it possible or will I have to create another plugins from zero just to run on Integration Services ?)
B) Assuming the previous step is possible, how to modify my plugins to define inputs and outputs to do the correct communications between each plugin ? I think this is the most important question. Is it simple to do ? Is there any documented examples ?
I have 25 columns in my excel which is the second row in the excel. I have merged column comprising of 3-4 columns so like wise 7 columns as the 1st row. How can I suggest SSIS that 2ns row in the header or column names? Is there a way to validate values in each cell in excel for their data types using SSIS? Also is there any way using SSIS that I can refer to specific cell in the excel?
Here i am going to ask some questions in SSIS pls clarify my doubts...
1. Can i include a package with in another package? like If i have 20 packages..i need to run all packages at a time ..for this can i create a package and can i place all those packages in to a single package?
2. If i have 700 packages then how to run those packages all at a time?
3.Can i develop a Workflow or package in SSIS with out using Data Flow Tasks? Like with the help of only control Flow Tasks can i create a package or workflow?
I have a SQL cluster 2005 with 2 nodes. I involved a ETL (DTS) on SSIS.
I used OLEDB to get a connection ORACLE and INFORMIX.
I used a user and password to authenticate.
When I publish the package, to the Integration Services.
I publish it to the MSDB so in case that we have a failover that the package is the same.
However in case of switching server (failover) the package that I published on NODE 1 does not run on NODE 2.
And it fail:
OnError,EDVSQLCLUSTER02,DOMAIN-LISBOA olo,Insert pt_fornsap,{F06434D9-431B-48B7-A3E6-F17E04A29488},{4FF70682-705E-4410-885F-36F25BC1EC8C},22-09-2006 2:00:01,22-09-2006 2:00:01,-1071636471,0x,An OLE DB error has occurred.

I have few more clarification regarding time series. Firstly In my model the month level product sales value represented across 1st day of every month. So that the key time column is of datetime datatype containing a sequence of dates representing the 1st day of every month of the year. Eg: 2006-01-01, 2006-02-01€¦€¦€¦. etc. all in (yy-mm-dd) format But when I make prediction for next five months, though it makes monthly predictions the date part for the months are random whereas I expect the date part to be 1st of every month. What is the reason for this and how can I overcome it. Secondly Predicted sales values for some time period are negative though I do not have any negative value in the training data. What is the reason for this and how can I rectify it?
Thirdly In one of your earlier posts you had said that the time series algorithm does not have any built in time intelligence but uses the key time column as a time sequence stamp. So If have to make predictions for a particular time period where the time slice for each time period is 25 days or 50 days etc, then I understand that the input data used to train the model should be in the same time sequence. Or Can I specify the span of the time period according to which the prediction needs to be made? Basically how can I use the same time series model to make monthly, yearly, quarterly, daily or predictions or for custom time period like I have mentioned above.
I am currently using SQL Server 2000 server. I have run some BCP command to import data to SQL from CSV and Text files with the help of FORMAT files through Windows Scheduler.
My doubt is, if I swich to SQL Server 2005, whether the same BCP commands will supported? If no, What are the things I need to do to run the BCP commands in 2005 as in 2000?
I heard that the BCP utility is no longer support in 2005 and this can be done thru SSIS utility. Is it right...? Is SQL Server 2005 support to use the BCP commands without going to SSIS utility?
