I'm pretty new to sql server and now I need to create a script that:
Compares the values of the row with the same id as the row with the update table(which has updated values in it) in which the price, description or replacement part have been changed.
If they did change they should be updated and if they haven't been changed nothing should happen...
I am relatively new to SQL and as a project I have been asked to create the SQL for a simple database to record train details. I want to implement a check constraint which will prevent data from being inserted into a table if the weight of the train is more than the maximum towing weight of the locomotive. FOr instance, I need to add the unladen weight and maximum capacity of each wagon (located in the wagon type table) and compare it against the locomotive maximum pulling weight (the locomotive class table). I have the following SQL but it will not work:
check((select SUM(fwt.unladen_weight+fwt.maximum_payload) from
hauls as h,freight_wagon as fw,freight_wagon_type as fwt,train as t where
h.freight_wagon_serial_number = fw.freight_wagon_serial_number and
fw.freight_wagon_type = fwt.freight_wagon_type and
h.train_number = t.train_number) <
(select lc.maximum_towing_weight from locomotive_class as lc,locomotive as l,train as t where
lc.locomotive_class = l.locomotive_class and l.locomotive_serial_number = t.locomotive_serial_number))
The hauls table is where the constraint has been placed and is the intermediary table between train and freight wagon.
I may not have explained this very well; but in short, i need to compare the sum of two values in one table against a values located in another table...At present I keep getting a message telling me the sub query cannot return more than one row.
How can I compare column in the same table and show only column and value that has been changed.
declare @t table (GroupID CHAR(6),Text1 VARCHAR(MAX),Text2 VARCHAR(MAX),Text3 VARCHAR(MAX))
insert into @t
SELECT '11111','Text1','Text2','Text3'
insert into @t
SELECT '11111','Text1','Text2','Text4'
END RESULTS:
Column Name Old New
Column 3 |'Text3' |'Text4'
When our DB was converted from 6.5 to 7, the some column check constraints changed
to table constraints.
Is there a way to change them back, short of rebuilding the table? I can't find a syntax
to add a column constraint without adding a column. Some of the affected tables contain
millions of rows, so I'd rather not rebuild them.
When I create a test table with a column and a table check, I see that in sysconstraints
"colid" and "status" are different, and in sysobjects "info" and "status" are different. I
am leary of tweaking the database catalog though. Heck, this is SQL 7; I don't even
know if these are real tables or mirages.
create table zzzfoo (
myname char(30) check (myname in ('foo', 'bar')),
myfuzz char(30),
check (myfuzz in ('cotton', 'wool', 'linen'))
)
select sc.* from sysconstraints sc, sysobjects so
where sc.id = (select id from sysobjects where name = 'zzzfoo')
and sc.constid = so.id and so.type = 'C'

Hi..
I got 10 Tables with data in it for 100 Loans. The data can be Good and Bad .....
I had a Update Proc which Updates the 10 tables with the Good data what ever i pass...for this 100 Loans
Tha Proc will update the existing data in all tables whether it is Good or Bad Data.
when the updating is completed I want to know what are the Loans that were updated where there is a Bad Data in atleast one Field of the 10tables.
I don't want to check field by field in each table.... if there is a bad data and my proc updated with a Good Data i want to know that Loan.
Can any one has an idea on this,,,,
Thanks

Hi All,
I receive the input file with some 100 columns and some 20k+ rows and I want to check the incoming input row is existed in the database or not based on 2 key columns. If the row is existed then I need to check all the columns (nearly 100 columns) values in input and the database are equal or not. If both are equal I need to treat them seperately if not there is a seperate logic. How Can I do that check for each row and for each column?
Basically the algorithm is like this, if the input file row is not existed in the database then treat that as new row else if the input row is existed in the database then check all the columns are equal or not. If all the columns are equal then treat that as existing row and do nothing else if some columns are not equal then treat this row seperately.
I found some thing to achieve the above thing.
1. Take the input row and check in the database.
2. If the row is not found in the database then treat it as new row.
3. If row is found in the database then
a) Take the source row and prepare a concatenated string for all the columns
b) Take the database row and prepare a concatenated string for all the columns
c) Find out the hash code for the 2 strings and then compare hash codes for equal.
The disadvantage of this is running a loop 2*m*n times where m is the number of rows and n is the number of columns. It should be done 2 times for input file row and database row.
Can anybody suggest a good method to do this?
What does the function "GetHashCode" for InputBuffer in method "Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer)" will do?
Will it generates hash code based on all the columns values?
Pls clarify.
Regards
Venkat.

I recently moved from SQL 2000 to SQL 2005.
The client side is vb6 and using Dcom dll's hosted on the db server.
I have a table which has oninsert trigger
When the recordset is updated in the com class it throws the foll error :
"Row cannot be located for updating. Some values may have been changed since it was last read."
The same code was working with SQL 2000 !!!
Any clues.

I am attempting to update a sql db using the update and parameter code in VB.net 2003 through MSDE for a web application. It updates changed data OK, but if the textbox value is deleted, the code does not update the sql db. I am new to this, and I'm sure it is something simple. Here is some sample code.
SqlConnection1.Open()
strSQLu = "UPDATE table1 " _
& "SET Field1Tag = @Field1Tag, Field2Tag = @Field2Tag " _
& "WHERE (Field1Tag = @Field1Tag) "
cmdCategoriesUpdate.CommandText = strSQLu
With cmdCategoriesUpdate
.Parameters("@Field1Tag").Value = txtFld1.Text
.Parameters("@Field2Tag").Value = txtFld2.Text
End With
cmdCategoriesUpdate.ExecuteNonQuery()
SqlConnection1.Close()
hi,
it is my first post on this forum, please be patient if i miss any important bit of information.
i am transporting data from a legacy system into mssql 2k5 using SSIS.
among those column of a dataset there are 13 columns, all necessary for operational reasons, that i need to ensure data consistance.
i believe i could do this check using the lookup data flow item, but surely there must be a way to do it in a more streamlined fashion.
since column names contain numbers to distinguish the version, eg; col01, col02, col03 .. col13.
i thought i could include the lookup within a loop and use a couple of variables to do this trick, but since i have not done it before i am asking for some sort of guidance from a guru among you folks.
please let me know if further clarification is necessary.
regards,
nicolas
Here is my statement:
Dim MyCommand As SqlDataAdapter
MyCommand = new SqlDataAdapter("select * from Request T1, Users T2 where RunID= "+ intRun_Num +" and T1.UserID = T2.UserID ORDER By Username", MyConnection)
I'm getting error saying:
Input string was not in a correct format.
the problem is the intRunNum. When I put intRunNum.toString(), there is no error but no results are coming up.
How do I get past this?

I'm stuck trying to compare date values from users selection against a database. I also need to add a condition statement on if the results return no match. How would I do that?
Also, I'm not even sure if my SELECT statement is right. The user will hit a date that will be in format m/d/yyyy and that will be compared to see if it exist in the database. The datebase column "date_created" is default with date/time( 8 ). But when I compare the to together, nothing returns back. The page loads successfully, but no results from the database.
Here is my code:
dim conpubs as sqlconnection
dim cmdSelectAuthors as sqlcommand
dim dtrAuthors As sqlreader
conpubs = New sqlconnection(configurationsettings.appSettings("STD"))
conpubs.open()
cmdSelectAuthors = New sqlcommand("Select * From HotNews WHERE date_created=" & y, conpubs)
dtrAuthors = cmdSelectAuthors.ExecuteReader()
Response.Write("<table><tr><td>")
While dtrAuthors.Read()
Response.Write(dtrAuthors("title") & "<br>")
End While
Response.Write("</td></tr></table>")
dtrAuthors.close()
conPubs.close()

guys this is kind of a biggie for me.
i've only used sql server to compare the Date Portion of date(s), not the whole string (mm/dd/yyyy hh:mi).
i have a table called Time_Check which has two fields with timestamps,
"TimeLastRun & TimeNextRun". i was trying to compare the Current TimeStamp that i pass from a vb.net form to a stored procedure and compare that DateTime to the TimeNextRun. I'd like to then Update the two Time Columns if rows are found. Should i maybe be using the DateDif Func if i know ahead of time how much time should be elapsed(say five minutes)?
Any Code help is appreciated
Create Procedure dbo.My_Time_Check
@myDate smalldatetime
as
select alertnumber,alertname,TimeLastRun,TimeNextRun
from time_check
where timeNextRun >= @myDate
--would like to update these two columns if rows are found
thanks again

thanks in advance.! any help?
well i actually get the answers by doin this...
select order1 from datetable group by order1 having count(*) > 1
however now i want to compare the values date1 in the first duplicate orders to the second duplicate order...like compare aaaa of the first row and aaaa of the second row ...how to do that? i need to compare the date1 in minutes..i only wan duplicate orders with minutes difference less than 30mins
eg
id Order1 date1
1 aaaaa 20051001 12:45

This is my first post and I am probably not using the correct terminology but I will try. I want to compare the value of one of my fields in a result set to the value of the same column/field, but from the previous row in the result set. I am trying to identify the row in the result set when the value in a specified column changes value. I want to identify this row by placing a 1 in the last column. If that value did not change, then place a 0 in the last column.
I am not sure if this will make sense to anyone out there. Please let me know if more clarification is needed and I will try to provide it. Thanks for all your help in advance.

I am trying to compare the last two values in the same column of atable. First of all, I have a column titled Row_Index that uses anindex which starts at 1 and increments by 1. What I am trying to dois compare the values in the column 'Shift_Date' for the maximum valueof Row_Index and the (maximum value - 1) of Row_Index. I've beentrying to declare two strings, setting each string equal to one of myvalues, and then comparing the strings. But this doesn't seam to beworking right. I'm not sure I am even declaring the stringscorrectly. Does anyone know how I can do this. A sample of what oneof my values looks like in Shift_Date is ' 6/25/2007'.

I have a table with one column. The values can be Y or N. How do I compare the 2 values and return a result depending on the comparison. For example, if I my column data looks like this.
Y
N
I need to compare them and if they match return a specific value and if they are different return a specific value.
I have 2 databases( "A" + "B") with identical number of tables and identical number of records for each table. There are also identical number of fields pre record per table. Table A has had the sensitive data within the fields scrambled.
I need to know if there is a way to read down each DB table by table, record by record, field by field and compare the data values. If they are different I need to output the Field name, the data value and the Table name from the Scrambled Table (lets say its "A").
I have the following variables VehicleID, TransactDate, TransactTime, OdometerReading, TransactCity, TransactState.
VehicleID is the unique vehicle ID, OdometerReading is the Odometer Reading, and the others are information related to the transaction time and location of the fuel card (similar to a credit card).
The records will be first grouped and sorted by VehicleID, TransactDate, TransactTime and OdometerReading. Then all records where the Vehicle ID and TransactDate is same for consecutive rows, AND TransactCity or TransactState are different for consecutive rows should be printed.
I also would like to add two derived variables.
1. Miles will be a derived variable that is the difference between consecutive odometer readings for the same Vehicle ID.
2. TimeDiff will be the second derived variable that will categorize the time difference for a particular vehicle on the same day.
My report should look like:
VehID TrDt TrTime TimeDiff Odometer Miles TrCity TrState
1296 1/30/2008 08:22:42 0:00:00 18301 000 Omaha NE
1296 1/30/2008 15:22:46 7:00:04 18560 259 KEARNEY NE

I need to determine if a value for a group of rows is the same or different and I am not sure where to begin. I am fairly new to writing T-Sql code. I am working with SQL Server 2005. This is a work assignment; I am not a student.
I have two tables: One for Course and another for CourseDays. As the Course table implies, it lists courses for a school. The CourseDays tables has a row for each day a course is held. For instance, one course maybe held on Monday, Wednesday, and Friday, so there would be three rows, one row for each day. A given course could be held in a different room for each day. I am trying to write a query that returns one row for each course, and if the room number is the same for each day the class is held, return that room number in the row, else return 'Various'.
Course table:
CourseID, Desc
1 English
2 History
3 Science
CourseDays table:
CourseID, Day, RoomID
1 M 320
1 W 445
1 F 680
2 T 123
2 Th 123
3 M 514
3 T 514
3 W 521
3 Th 901
3 F 521
Expected results:
CourseID, Desc, RoomID
1 English Various
2 History 123
3 Science Various

1. ITEM 2 (id=11) is not returned because it has the assignment to category 'SQUARE' in master cat 2 additionally
2. ITEM 3 (id=12) is not returned because it has the assignment to category 'BLACK' in master cat 1 additionally
3. ITEM 4 (id=13) is not returned as it does not have assignment to category 'CIRCLE' in master cat 2 but only to 'WHITE' in master cat 1
3. ITEM 5 (id=14) is not returned as it does not have assignment to category 'WHITE' in master cat 1 but only to 'CIRCLE' in master cat 2

I was wondering if anyone knew how to take a value from a subreport and
compare it to a value iwthin the main report. We are trying to see if
the value in the subreport is greater than the value returned in the
main report. We want to make the value test red if it is greater than.
I know how to compare these values if they were in the same report, but
when it comes to subreports I am lost. Any ideas? Thanks in advance.
