hi,
i'm wondering if there's a possibility for me to insert values into a table without knowing fix number of fields? in other words, i won't know how many fields i have in a single table until users enter data.
any suggestions or recommendations are welcome. thanks in advance.
what is the best way to uses ssis to deal with a CSV file that contains a number of records that contain a different number of fields ?
I could just load as a single column delimited by <CRLF> but then I would have to write the code to parse the line, effectively detokenising the columns myself but if that is the case then why uses ssis at all ?
Hi,
I have a fairly basic query I want to make but I'm struggling on figuring out how to do it. Let's say I have some fields (e.g. Value1, Value2, Value3, etc). I simply want to do a Select statement that returns the highest value among those fields for every row in my db.
At first I thought of the built in Max function until I realized that is for within a column only.
Any help would be appreciated, thank you.
My users login from the tbl_users table.
I would like to store all information on them in this table but that amounts to quite a lot of fields (about 50) and some of these will store a lot of HTML text in them.
Is it best to split the table up for performance reasons or will it make little difference?
Thanks,
JB
I'm new to SQL Server 7. Is there a limit to the number of fields that a table can have?
View 1 Replies View RelatedI have a Column named 'Series' and a column named 'Linenumber'. They look like this:
Series Linenumber
234 NULL
234 NULL
235 NULL
235 NULL
234 NULL
234 NULL
235 NULL
235 NULL
236 NULL

And I want to run a query and make it look like this:
Series Linenumber
234 1

235 2
234 3
234 4
235 3
235 4
236 1

So basically I want Linenumber to be an increment column but to increment seperately for each value of Series. RDBMS is Microsoft SQL Server 2008.
I am working on a project which requires having a form that must be filled by the user. The number of the fields on this form is arround 150. Is it a good idea to have a database table with 150 fields (columns)? If its not what would be a better approach for this case? Handling this many fields on a windows form is another issue but first I would like to know about how to deal with the data storage.
Any help is appreciated.
Thanks

View 4 Replies View RelatedWhat I need to do is re-populate a unique number into multiple fields,
Let me explain, An employee can appear in the first table only once but can be in the second table multiple times with multiple employee numbers .There is a field called TFN that is unique and we are using it to create a unique id called KRid so what I have done is created 2 tables namely TEST_TBL and TEST2_TBL . In TEST_TBL I am populating a KRid with a unique no being produced by the TFN field only once i.e 12345 being the resulting unique id number. If an employee has 2 employee numbers i.e empno 1 and empno 1000,only employee no 1 will have the unique KRid created but nothing for 1000 because the record already exists , so what has me stumped is that the TFN for employee empno 1 and the TFN for empno 1000 are the same. How do I get the KRid (12345 from empno 1) to populate empno 1000 in TEST2_TBL , The second table has all records in so I can group the second table by TFN id but how do I populate employee 1000 in the second table with the KRid 12345.
Please help!!!!! Below are how the tables are set up and an example of the result.

Query goes as follows for table 1:
SELECT NPE000.EmpNumber, NPET00.RecordStatus, NPE000.KR_ID, NPE000.Surname, NPE000.FirstName, NPE000.SecondName, NPE000.Class, NPE000.DateEmployed, NPE000.DateOfBirth, NPE000.HoursPerDay, NPE000.HoursPerWeek, NPE000.PassportNo, NPE000.AwardCode, NPE000.EmailPayslipTo, NPE000.Location, NPE000.Grade, NPE000.DateTerminated, NPE000.EmploymentType, NPE000.DistCode, NPE000.EmpStatus, NPET00.TaxRefNo FROM NPE000 NPE000, NPET00 NPET00 WHERE NPET00.RecordStatus = 0 and NPET00.TaxRefNo <> ' 111111111' and NPET00.TaxRefNo <> ' 000000000' AND LENGTH(NPET00.TaxRefNo) >= 9 AND LENGTH(NPE000.KR_ID) >= 0 AND NPE000.EmpNumber = NPET00.EmpNumber
Query goes as follows for table 2:
SELECT NPE000.EmpNumber, NPE000.FirstName, NPE000.Surname, NPE000.Class, NPE000.Location, NPE000.EmploymentType, NPE000.EmpStatus, NPET00.TaxRefNo, NPE000.Paypoint, NPE000.KR_ID, FROM NPE000, NPET00 WHERE Recordstatus = 0 and (EmploymentType = 1 AND EmpStatus = 1 AND NPE000.EmpNumber = NPET00.EmpNumber
From this you can see that in table 1 it will only create 1 KR_ID for only one employee number but in table 2 I am bringing through all employee records. In table 2 I can group by NPET00.TaxRefNo which will bring all NPET00.TaxRefNo's togeather. From that I would like to populate the other employee numbers with the unique KR_ID.
Example:Table 1
000001,Jackson,James,Sam,7.6,38,12345,475431212
Example:Table 2
000001,Jackson,James,Sam,7.6,38,12345,475431212
001000,Jackson,James,Sam,7.6,38,,475431212
I hope this helps
Thanks in advance
Hi folks....
I am able to import a CSV file into a temporary table as long as I know the number of fields in the CSV file. Here is what I would like to do:
I would like to have a CSV file which has UP to 6 entries per row. I would like to insert each row into a table; if the there three fields, then I want to insert them into the first three columns to the temporary table. If there are four, then insert into the first four fields. Is this possible?
Does anyone have any suggestions?
Thanks!

I'm writing a query that will be used in Jasper Ireports, but prefer to have the values done ahead of time using SQL rather than relying on the report to do the lifting.The fields are pretty straight forward, only the display is where I have a question.
Fields Used: PERIOD ('MON-yyyy') and VALUE
The results must start with the CURRENT PERIOD (AUG-2014) in one column and the VALUE for the current period multiplied by 1/12 (VALUE*(1/12)).The next column should return the VALUE for CURRENT PERIOD - 1 (JUL-2014) and multiply by 2/12 (VALUE*(2/12))
This should continue for the last 11 months and would end with OCT-2013 with the value being multiplied (VALUE*(11/12)).Is the easiest solution to this a CASE statement looking at PERIOD then PERIOD minus one month, minus two months...etc?
I need to associate aggregate gross_revenue with calendar year, but do not have a date field that reflects payment dates, just contract periods a start_date and an end_date. The contract periods are typically 1 or 2 years and can start at any time I.e start_date 6/1/2012, end date 5/31/13. I think by finding the number of days that fall in each calendar year and storing in a temp table, I can create a simple formula to associate revenue to each year.

For example in a table with this fields "field1, L1,L3,L100" field2 the count is 3
it would be better to match a number into the like but i thinks it cannot be done in the like so i've to add another condition to ensure all the text after L is a number.
is this the best way to do it?
Select count(*) from Information_Schema.Columns Where Table_Name = @Table
AND column_name like 'L%' and ISNUMERIC(SUBSTRING(column_name,2, len(column_name)-1))=1
Im trying to determine the best way to store data gathered from a form that a user will fill out online. The form is dynamic and is customized at run time based on group-specific criteria. The end result is a form that might have 3 extra text boxes, 2 extra sets of radio buttons and a freeform textbox, whereas for another group, there might be a slightly different set of input fields. Now comes the issue of storing this data. Since the fields can be somewhat dynamic, it could get tricky to define table columns for each possible input field. So Im considering storing the data as xml. Has anyone else had to build custom forms and ended up storing the data as xml ?

How can I search for all the O'Connor's in my SQL Server database?eg: SELECT [Surname] ,[FirstName] FROM [myDB].[dbo].[Names] WHERE ([Surname] = 'O'Connor')
View 5 Replies View RelatedHi I have a table in my database and one of the columns is called 'Month'. Here only one month is inserted according to what the user selects from a dro down list.
WHat i want to be able to do is find the average of the column 'ScoreOut' on a month by month basis. My code works fine if th database contains at least one row with every month of the year represented.

Hello,
I have a global report which contains many countries, and I want a specific user (let's say French) to access only to a specific country (France).
So far in SSAS, I have created a role, and assigned my user to this role. When I browse the cube with the new role, I see only the information regarding the country France.
However when the user access to the report through the web interface he can see all the countries. Moreover when I browse the cube with the user (DomainUserName) which belong to the role, I can see all the countries.
So I think I have missed something about role security and the link SSAS-SSRS...
Do you have ideas about how to deal with my problem?
Any help is welcome...

Hi,
My company is starting to use nvarchar columns in our database products. We just found out that, suppose table T1 has a my_nvarchar_col column, and there is a row containing a unicode text say "some Chinese", if you want to select that row, you have to append "N" in front of the unicode constant in the "WHERE" clause. That is:
select * from T1
where my_nvarchar_col = N'some Chinese'
will return that row, while
select * from T1
where my_nvarchar_col = 'some Chinese'
will return NOTHING.
This brings us a huge problem - we have tens of thousands of such queries in our existing PowerBuilder code base. Do we have to go through all of them to add "N" to the "WHERE" clause? Is there a way we can set some attribute of SQL Server so that we do not need to do that?
Project stalled and I am under extreme pressure so please help ASAP!!
First we need to run all packages for initial loading and then we need to run all packages every night.
But inside all packages we need to mark some records as invalid data.
How to deal with all these invalid data after data migration?
If I reject to transfer these data, I will get reference error during next data migration loading.
Hi please could someone give me a explination of how SQLserver deals with multiple databases, We have multiple website that are all run from the same server all from SQLserver. Now we have a couple of databases which are very busy and have a lot of people constantly accessing them and then we have quite a few with much less traffic.
How would these databases effect each other? Would the busy database, mean that the many small databases will all be slowed dramtically?
Everything is okay at the moment but we are considering putting another fairly large database on the server and am worried about it having a sever effect on the smaller databases. Cheers Ed
Try hard to become familiar with T-SQL.Can anybodey tell me the best way to deal with set's provided by astored procedure. Til yesterday I thougt trapping set in temp tableusing INSERT EXEC is a way out of this, but then I struggeled withnested INSERT EXEC's.What are all the system proc's good for if the results cannot beevaluated? The approach of modular programming is to have code doingsimilar things in one place.If I try to make use of sp_helprolemember to get login names for moreroles, pack the logins in one table and return the result set in a SP,the procedure which calls that is unable to evaluate the set.On the other hand I read the advice, not to access system tablesdirectly.Is there a way out?

Hi, all experts here,
Thanks for your kind attention.
I have a question on missing_value substitution. As we know in the algorithm parametres setting, there is an option for us to select the method to deal with the missing_value: None, Previous, or Mean. My question is: to numeric data column, we can select Mean method to deal with its missing value. But how about discrete type of data column? What is the best practice to deal with this kind of data? I do think it to a great extent matters the quality of the models being trained?
Can please any of you guys here give me any advices and suggestions on this based on what best practices you have got?
I am looking forward to hearing from you shortly and thanks a lot in advance.
With best regards,

First a bit of background.
We use the Windows-logon to authenticate en identify the user. With this logon we check within most of our reports what a user is allowed to see.
Depending his level or geographical location he is allowed to run reports on one to all sites. He can selects the sites from a Multiple Select box. This works fine.
Now, we want to use data-driven subscriptions, I understand why we can't use this parameter, but how do you people deal with this kind of configurations.
I would prefer not to 'double' the reports in a normal and a subsciption version .....
I try to convert a Procedure that join 8 tables with INNER AND OUTER JOIN, my understanding is that the Lookup task is the one to use and I should break these joins into smaller block, it takes a long time to load when I do this, since each of these tables had 10-40mill. rows and I have 8 tables to go thru, currently this Stored Procedure took 3-4min to run, by converting this to 8 Lookup tasks, it ran for 20min. has anyone run into this issue before and know a work around for this.
