I am trying to compare values from two columns but I don't know what I am doing, I tried select custom5,skipcount substr( custom5, 1, 4) as 'mynumber' from songs where custom5 > '0000%' where skipcount > cast( substr( custom5, 1, 4) as int ); But that is obviously wrong?
View 4 RepliesHi 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 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.
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 am trying to compare columns in two tables with a wildcard character.
One table: Other Table:
----------------------
ID Col1 | ID Col2
---------------------
1 1 1 1A
1 1B
2 2 2 2A
3 3 3 3A
4 5 4 5A
4 5B
4 5C
5 7
6 27
7 50 7 50A
-------------------------------
I want to writing something like:
SELECT Table1.ID, Table1.Col1, Table2.ID, Table2.Col2
From Table1, Table2
WHERE (Table1.ID = Table2.ID) AND (Table2.Col2 LIKE Table1.Col1%)
which obviously does not work.
basically "column2 Text%" so if ID = 1, Col1 = 1 => will have the following comparisons turn out true:
1A LIKE '1*'
1B LIKE '1*'
How can I do a comparison like 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

Hi
i have this variable called order1 in the table called datetable and i want to display out the duplicate orders in sql. how do i do that? do i need to use group by ?
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
2 aaaaa 20051001 12:10
3 bbbbb 20031002 15:05
4 bbbbb 20031002 15:50
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'.

View 4 Replies View RelatedI have one database with several tables in it (table 1, table2, table3). In each table is two colums (colum1 = a number (201220) and colum2 = a number (0.50). Now, both tables will have rows with the same data in colum 1, but colum two will have different numbers (different prices). My goal is to run a query that will compare both colums in all three tables, take the lower of the three based on colum 2 and spit out the row. Obviously, this would output all rows (around 175k). The point is to create a least cost spreadsheet (csv) file based on evaluating all three tables.

Below is a query that I have written to obtain some information. The problem arises when we have a patient who goes from Patient Type '1' to Patient Type '2'.

I have two table with the same name that reside in different databases. The two database have the same name, but reside in two linked servers
TABLE A: [ServerA].[ProdDB].dbo.[Orders]
TABLE B: [ServerB].[ProdDB].dbo.[Orders]
How do i find out if the two tables have the same number of columns or if the a column that exists on TableA does not exist on TableB.
Does any one have a script that could help me with this task. Thanks
I am using SQL Server 2005
I have a situation in SSRS to get the common values between the two columns where the values are sorted comma separated as below.Ex:
ColumnA :  abc,cde,efg  Â
ColumnB : cde,xyz,abc  Â
the result in  Â
ColumnC : cde,abc
similarly Column A and B will have n number records. I need to right an expression or the Code function to get the required result in ColumnC. I am using SharePoint Lists as Datasource. Cannot write SQL query to achieve this requirement.
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'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 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

Hi Guys.
I have a problem. I have two feilds in a table. Both of them are (int). I want to be able make sure the same number is not put in both columns for each row. Both colums have to be a different number, and also if one is null, the other cannot be. How do I go about enforcing this policy?
For Example:
This is what I want
ID Column1 Column2
--- -------- ---------
1 5 8
2 5 7
3 null 10
4 6 2
This is what I DO NOT want:
ID Column1 Column2
--- -------- ---------
1 5 5
2 5 5
3 7 7
4 null null
I created a unique constraint between the 2 columns, but it still allows dups within the row. Please help me.
How would I compare 2 rows to find the difference in the columns?
Example:
ID Column1 Column2 Column3
1 Text1 Text4
2 Text1 Text2 Text3
Result:
Column1: Text2 New
Column3: Text4 Old Text3 New
