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
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 RelatedHow can I create a Table whose one field will be 'tableid INT IDENTITY(1,1)' and other fields will be the fields from the table "ashu".

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.
I 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
236 NULL
236 NULL
And I want to run a query and make it look like this:
Series Linenumber
234 1
234 2
235 1
235 2
234 3
234 4
235 3
235 4
236 1
236 2
236 3
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.
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.

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

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
Hi
I want to enter rows into a table having more number of columns
For example : I have one employee table having columns (name ,address,salary etc )
then, how can i enter 100 employees data at a time ?
Suppose i am having my data in .txt file (or ) in .xls
( SQL Server 2005)
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 ?
I have a list of items in one table and a field (pageName) in another table that may contain one of the aforementioned items somewhere within that field. There is no fixed position within the field where the itemNo may be so I can't just use SUBSTRING(pageName,2,5) in(select itemNo from tblItem).
Logically, it's like I need to combine IN and LIKE: select pageName where pageName LIKE IN %select itemNo from tblitemNo%..LIKE can only handle one comparison string.
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 ?

I have 2 tables with 2 fields in common between them. How do I get a count of rows in table 1 but not in table 2 matching those 2 fields? Thanks.
Hello all:
Is it possible to creates fields of the table dynamically?. I have this situation in my project. This is just a small sample. I have row of length 140. I don't wan't to declare all this fields manually using the create table command.
The description of table is as, in this table all the field are of type varchar only, there are like 140 columns.
create dummy emp (
field1 VARCHAR(100), field2 varchar(200), field3 VARCHAR(100).... )
Table: Dummy
================================================== ==
field1 field2 field3..........
Empid Empname empaage1 sam 23...........
2 rai 22............
.
.
.
n raj 45.............
================================================== ==
Now I want to create another table as "EMP" , with proper data type
fields too..
create table emp (
empid int, empname varchar(100), empage int....)
The table should look like as:
Table: EMP
================================================== ==
Empid Empname empaage............
1 sam 23...............
2 rai 22................
.
.
.
n raj 45.................
================================================== ==
I want to do this dynamically.....
Some how I need to extract those field from table[dummy]; the first row acts as a column header for the table[Emp] and the subsequent row acts as a record for the table[Emp]
A small rough snippet of the code will be appreciated....
Waiting for replies........

Hello,
I am receiving the following error:
Column name or number of supplied values does not match table definition
I am trying to insert values into a temp table, using values from the table I copied the structure from, like this:
SELECT TOP 1 * INTO #tbl_User_Temp FROM tbl_User
TRUNCATE TABLE #tbl_User_Temp
INSERT INTO #tbl_User_Temp EXECUTE UserPersist_GetUserByCriteria @Gender = 'Male', @Culture = 'en-GB'
The SP UserPersist_GetByCriteria does a
"SELECT * FROM tbl_User WHERE gender = @Gender AND culture = @Culture",
so why am I receiving this error when both tables have the same
structure?
The error is being reported as coming from UserPersist_GetByCriteria on the "SELECT * FROM tbl_User" line.
Thanks,
Greg.

Hi,
I am new to sql and is working with sql server managment 2005 +c# 2005.
My application needs to create a blockdiagram sort of thing say
if in my database i got a table 'Addition' with 'a', 'b', 'c',and the primary key addition_id, and c is related to a and b as c = a+ b.
there is stored procedure name usp_addition which contains this relation. Each time any insert or update is done this sp is executed and all the values are updated for accordingly.
My problem starts in the front end where i need to draw the graphical representation of table addition.
In this graphical representation, I need to draw the labels a, b, c and the arrows from a and b which will connect to c, showing that c has a, b as inputs.
I got the label using dataset and datacolumns but hte problem is how to create the arrows the name of labels (i.e my column names from which the arrow should start and end)
How does I get the information that c as two inputs a, b. I dont need the values since i just want to view the columns in table and which column is input to another column.
Since I need to do this dynamically because my tablename, and the number and name of column would differ does any body knows how to do this.
