is there a way to process a file x records at a time?
We have a table that I need to append to an existing table. The date columns are currently in char but must be converted to datetime for the existing table. The problem is I have bad data. There are 3 million rows where the date field isn't valid for SQL's datetime format. Since this is the data I have, I have to work with it. I would like for SQL to just insert a null if it comes upon a bad date. Currently when it encounters a field that isn't valid, it stops the process with an error.
I have tried to go around it below, but there is still something "hanging" I would like to be able just to insert one million rows at a time and if it errors, then I can look at the next million, find the error, fix it and continue on.
Any suggestions? Or if you have a better idea all together I would love to see it.
SQL Server 7.0, SP2
,CASE
when
(substring(check_date,1,4) not between '1997' and '2000' or
substring(check_date,5,2) not between '01' and '12' or
substring(check_date,7,2) not between '01' and '31') THEN null
ELSE cast(check_date as datetime)
END AS check_date
have created a Database Application in Java and display all the records in tabular format of one Table. This table have Millions of Rows, If I run Select * from Table, then my Machine not responding, so Now I wants to add paging of 1000 rows at one time.
Is there are any option/query to read block of rows at one time and then query again for next page ?
i.e In MYSQL have LIMIT clause with Select Statement
I am trying to add the hours between each time block stored in a database.
In this database a user enters the begin time and the end time. For example the course MATH0001 would start at 8am and end at 10am. Therefore the user would enter 0810 in the start field and 1000 in the end field. The course MATH0001 doesn't run the entire semester it may only run from 8th Jan - 15th March and the course is scheduled in a room called GR4. Now because a course can be scheduled modularly, one room could have several courses scheduled in this manner.
The problem: I need to find out how many hours GR4 is used but it contains the following courses
A day only has 13 hours. Therefore the total hours spent in GR4 should be 12 hours. This is calculated by adding the hours between 8am and 5pm = 9 hours and 5pm an 8pm = 3 hours. I would not include 9am to 1pm because it is a subset of the 8am to 5pm slot.
Now, how to accomplish this but below is the code that i have thus far:
I forgot to mention that this code was to just test my 'final code' results and it outputs the table shown above. Anyway for testing purposes I have limited the search to the room GR4 and the day Tuesdays.
Code: select DISTINCT ssrmeet_room_code, ssrmeet_start_date, ssrmeet_end_date, ssrmeet_crn, ssrmeet_begin_time, ssrmeet_end_time, (((CAST(M.SSRMEET_END_TIME AS INT))-(CAST(M.SSRMEET_BEGIN_TIME AS INT)))+10)/100 As HoursPerClass,
I have a stored procedure that runs every 5 minutes. I have one block in the procedure that will only run if there are records in a temp table. In addition, I would like this block to run only if the current time is between 0 and 5 minutes past the hour or between 30 and 35 minutes past the hour.
Currently, my block looks like this: IF OBJECT_ID('tempdb..#tmpClosedPOs') IS NOT NULL BEGIN
I can get the current minutes of the current time by using:
Select DATEPART(MINUTE,GetDate())
I know that it should be simple, but I'm pretty new at Stored Procedures. How do I alter the IF statement to check for the time and only run the block if it's between the times I stated? I started to DECLARE @Minutes INT, but wasn't sure where to go from there.
I'm stuck. I have a table that I want to pull some info from that I don''t know how to.
There are two colomuns, one is the call_id column which is not unique and the other is the call_status column which again is not unique. The call_status column can have several values, they are ('1 NEW','3 3RD RESPONDED','7 3RD RESOLVED','6 PENDING','3 SEC RESPONDED','7 SEC RESOLVED').
The call_id could be any number, I only want the 6 PENDING rows where there are other rows for that call_id which have either 3 3RD RESPONDED or 7 3RD RESOLVED. If someone knows how it would be a great help.
I have the following stored procedure to test scope of variables
alter proc updatePrereq @pcntr int, @pmax int as begin
[Code] ....
In the above script @i is declare in the if block only when the @pcntr value is 1. Assume the above stored procedure is called 5 times from this script
declare @z int set @z = 1 declare @max int set @max = 5 while @z <= @max begin exec dbo.updatePrereq @z, @max set @z = @z + 1 end go
As i said earlier `@i` variable exists only when `@pcntr` is `1`. Therefore when i call the stored procedure for the second time and so forth the control cannot enter the if block therefore @i variable wouldn't even exist. But the script prints the value in `@i` in each iteration, How comes this is possible should it throw an error saying `@i` variable does not exist when `@pcntr` values is greater than `1`?
Does anyone know how to select rows by their position in a table. I need to be able to e.g return the 2,000th - 2,200th rows as a set. I will have many concurrent clients connecting to this table so I do not want to use cursors. The table is 800,000 in length. Any ideas people?
Hi,I am having a problem with aquery. Firstly here is a script to createthe table and insert some sample data:CREATE TABLE [dbo].[tbltemp999] ([Machine_Name] [char] (17) COLLATE SQL_Latin1_General_CP1_CI_AS NOTNULL ,[EventDate] [datetime] NOT NULL ,[EventID] [int] NOT NULL) ON [PRIMARY]GOINSERT INTO tbltemp999 VALUES ('MOBL','2004-08-16 12:05:14.000',6006)INSERT INTO tbltemp999 VALUES ('MOBL','2004-08-16 12:08:32.000',6005)INSERT INTO tbltemp999 VALUES ('MOBL','2004-09-22 12:24:45.000',6006)INSERT INTO tbltemp999 VALUES ('MOBL','2004-09-22 12:28:25.000',6005)INSERT INTO tbltemp999 VALUES ('MOBL','2004-11-03 17:53:38.000',6006)INSERT INTO tbltemp999 VALUES ('MOBL','2004-11-03 17:57:02.000',6005)INSERT INTO tbltemp999 VALUES ('MOBL','2004-11-04 12:09:10.000',6006)INSERT INTO tbltemp999 VALUES ('MOBL','2004-11-04 12:12:48.000',6005)The EventIDs 6005s represents a system start up and an EventID 6006represents a system shut down/restart. I already have a query tocalculate the downtime of a particular date range. So when i want tofind the total uptime of a date range in the past i do the following:Date1 00:00:00.000 to Date2 23:59:59.999 then subtract the downtime.My problem arises when Date2 is todays date as the time of23:59:59.999 would not have reached so the calculations are alwayswrong.How can I make the Date2 also read the current time?If this is vague info feel free to ask me to explain better.ThanksSunny
Your help is greatly appreciated. How do you query each one of the following:
1) SELECT FieldValue WHERE DateTime is from 8:30AM - 12:00PM and 6:00PM - 9:30PM on Mondays thru Fridays (i.e. exclude Sat & Sun) for the whole month of January 2008.
2) SELECT FieldValue WHERE DateTime is from 9:30PM - 8:30AM on Mondays thru Fridays, AND ALL-DAY on Saturdays & Sundays for the whole month of January 2008.
Hi, I want to select the 8 most saled products from large orders table... the problem is that when i use the "distinct" sentence (something like this- "SELECT TOP 8 distinct id, products, productid FROM tbl_orders ORDER BY id") I get back the distinct of any columns.... (and any ID is distinct, of course), but if i don't include the id's in the distinct sentence, i can't order by id's. can i get the last orders, only by distinct product, and not by distinct id, and order them by the id's?

I have two tables a stock table and a price table and I want to select the correct price for the Stock Date.
Problem is sometimes there is a promotion date in the price table between the live dates so the rows double up. Below is my sql but I get over 17,000 rows when it should be about 16,964.
I will post up the table and data.
SELECT a.[Company] ,a.[ProductID] ,a.[ColourSize] ,a.[StockDate] ,a.[Quantity] ,b.[Ticket Price] FROM[Stock_Ledger] a LEFT OUTER JOIN [Product_Prices] b ON a.[Company] = b.[Company] AND a.[ProductID] = b.[ProductID] AND a.[ColourSize] = b.[ColourSize] AND a.[StockDate] BETWEEN b.[StartDate] AND b.[EndDate] ORDER BY a.[StockDate],a.[ProductID],a.[ColourSize]
I have a table stock, on the table I have company_name, stock_value, sector. Now I want to get top five rows from this table depending on the five highest value of stock_value and for each sector. The query has to run on both oracle DB and Microsoft SQL Server with top priority MSSQL. I will appreciate if you help me on this
I know I can use "First" to specify a number of rows to return from a query but is it possible for the number of rows returned to be based on a parameter, something like this:
SELECT FIRST @someNumber name, age FROM friends WHERE age > @ageInput

hi!I have two tables with same structure. I need to run a select query thatwill return only the rowsfrom one table that are not in the other.In MySQL it would beselect * from table1 MINUS select * from table2.but in MsSql I can not find the apropriate way to do this.Any Help?Zvonko
I was wondering how you perform a select statement based on a specific date that will show all the records no matter which times belong to the specific date.
I have been having trouble with this one when using a single date, I think this is because of the time property as no records are displayed.
I have questions and answers from one table, I need to select questions as column names and answers column values as the results for the questions column.
I got the following query:SELECT TOP (8) ext.extID, ext.Quote, ext.sourceTitle, ext.extRating, gf_game.gameID, gf_game.catID, gf_game.URL, gf_game.TitleFROM gf_game_ext AS ext INNER JOIN gf_game ON gf_game.gameID = ext.gameIDWHERE (ext.Approved = 1)ORDER BY ext.extID DESC which is e.g. producing this output: 6000 -some text- Title 90 1960 2 tom-cl tom cl5999 -some text- title 90 1960 2 tom-clcl asdf5998 -some text- title 90 1959 2 tom-cl-cl asdfWhat I'd like to do now is to filter out the duplicate GameIDs (= 1960) so that just one unique row with the gameid 1960 is remaining. If I put in a SELECT DINSTINCT TOP(8) it just counts for the table ext, but I need it to count for gf_game.gameID - is that possible?Thanks a lot!
I have to select rows based on if the transaction date = todays date.The column is defined as numeric 8 with 0 decimal.how to code for todays date with such a column?
I would like to filter the second table taking one row per ID of Field A (first table) and selecting the rows whose sum of E is equal to the value in field C; in this example the resulting table should be:
SELECT RN_TEST_ID AS 'Test ID', MAX(RN_EXECUTION_DATE) AS 'Last Execution Date', MAX(RN_EXECUTION_TIME) AS 'Execution Time', RN_DURATION AS 'Run Duration' FROM RUN
1. The query should only return one record for each test id
2. The record returned should be the most recent. By most recent I mean the RN_EXECUTION_DATE and RN_EXECUTION_TIME of the returned row should be the most recent in time.
For example, in the sample data there are multiple rows with the same test id (for example 10668 and 10525. The 10525 is even more problematic since its execution date is the same for both rows returned - the execution times differ. Again, I want one record per test id and that record should be the most recent in time.
As a beginner i am having trouble with this. i have two different tables , both have a name column, nvarchar datatype. I would like to select from table B all the rows which contain a name which is not in table A. Then insert these rows, into table A
tried a few different ways & just keep getting strange errors that refer to courier font ??
