What Value Should I Update To SQL Table If Nothing Is Entered?
Oct 22, 2005
My form has an optional field for date entry. If user did not enter anything then how can I still maintain null value in the table in an update operation? Thanks for advice.
I'm entering a Selection record for a partiuclar lotID, Once entered, I need to obtain its SelectionID then use it to update a another field within that record. Here's what I've been doing... --insert values into a testchangeorders table INSERT INTO testchangeorders VALUES (2,3,3,3,1,'red',0,5) --Find the SelectionsID of the last record created for that partiuclar LotID SELECT MAX (SelectionsID) FROM testchangeorders WHERE LotID = 2 --Once located, I was trying to update a field called uniqueID with a contantination of '3-' & the record's SelectionsID UPDATE testchangeorders SET UniqueID = ('3-' & SelectionID WHERE SelectionsID = SELECT MAX (SelectionsID) AND LotID = 2)
I have 2 SQL server 2000 machines, I need to take a table from each one and combine them together based on a date time stamp. The first machine has a database that records information based on an event it is given a timestamp the value of variable is stored and a few other fields are stored in Table A. The second machine Table B has test data entered in a lab scenario. This is a manufacturing facility so the Table A data is recorded by means of a third party software. Whenever a sample is taken in the plant the event for Table A is triggered and recorded in the table. The test data may be entered on that sample in Table B several hours later the lab technician records the time that the sample was taken in Table B but it is not exact to match with the timestamp in Table A. I need to combine each of these tables into a new SQL server 2005 database on a new machine. After combining the tables which I am assuming I can based on a query that looks at the timestamp on both Tables A & B and match the rows up based on the closest timestamp. I need to continuously update these tables with the new data as it comes in. I havent worked with SQL for a couple of years and have looked at several ways to complete this task but havent had much luck. I have researched linked servers, SSIS, etc Any help would be greatly appreciated.
I have a table where the designer allowed time reporting for 8 different types of activity on each timecard, then stored the hours by activity in 8 separate columns in the database. Example:
Table A. Column Headers: Employee|Date|Phase1Hours|Phase2Hours, etc... Data: Fred Jones| 7/15/13 |3|3, etc...
The problem is there is no way based on this structure to get an employee's hours for the day in columnar form.
To get this data into columnar form I have used Select queries with Union All, for instance:
SELECT Employee, Date, Phase1 FROM Table A UNION ALL SELECT Employee, Date, Phase2 FROM Table A ,etc.....
Query is running slow (I am guessing it is because the same table is repeatedly being accessed).
I need to have a script where it ask the user for a value, the script will search for all records that match the value. Then it will display the numbers of records found and ask the user to enter a different value. The rest of the script will use this new value and increment by 1 n times as the number of records found. I started the script where it will ask for "HANDLE" and display the number of records found with that "HANDLE"
declare @HANDLE as varchar(30) declare @COUNT as varchar(10) declare @STARTINV as varchar(20)
set @HANDLE = ?C --This is the parameter to search for records with this value set @STARTINV = ?C --User will input the starting invoice number SELECT COUNT as OrderCount FROM SHIPHIST where HANDLE = @HANDLE
I just can't figure out how to proceed to use the entered invoice # and increment by 1 until it reach the number of records found.
This will be the end results:
Count=5 --results from query STARTINV=00010 --Value entered by user

Hi
Probably a dumb question but I'm doing an insert into a table with an identity field. How do I get the key back straight after I add it?
Is there a way to get the last ROWGUIDCOL entered into a table? I don't believe that doing a SELECT MAX will work, and we really need a way to do this. Does anyone have a nifty way to do this?
Hi every one I want to get the currently entered or updated record in the database table by using SQL Query or stored procedure. Thanx in advance Take care Bye

My database has many table, each table has a DateEntered (datetime), EnteredBy (nvarchar(50), LastUpdate (datetime), and LastUpdateBy (nvarachar(50). Is there an easy (ha) way to pull a list of the records that were entered and/or updated for a date range. Hopefully without a select for each table. Maybe a tool someone knows of?
Hi I have the problem that the below defined paramter gets entered in the database as a interger. the Field in the DB is a nvarchar(5) and the controll that suplies the value is a TextBox this is the parameter definition:<asp:ControlParameter ControlID="tbComment" Name="Comment" PropertyName="Text" Type="String" /> Why do I get this error, why does ASP to whant to make an integerfrom this text field? When putting a interger value in the textbox all works well and the data gets posted to the database. I use a SqlDataSource with automatic generated script.
I have a VB.NET program that displays the time extracted from a SQL Server database datetime datatype by way of a User-defined scalar function I created. However, sometimes information is entered into the system through the program that does not have a time-- only a date. SQL Server automatically assigns a time of 12:00 AM to these values (since they're a datetime). Is there any way to detect when this happens in my user-defined scalar function so that when I try to extract time values, I can instead return a message/time of my choice? I would rather not assume that all 12:00 AM values are automatically inserted by SQL Server since this might not actually be the case.
I have a procedure that allows a user to enter two dates to run a query. I would like to display those dates on the generated report underneath the title. "5-01-07 to 5-31-07" How would I do this?
I'm having a problem with some data in our database, basically a web app is storing data into the DB and then recalling it to display to a user. The problem I am having is that for one particular function the DB is causing the app to fail, the app code works for 95% of the data inserted into the DB by the users but it is failing on a few records.. I'v gone through the data manually checking for funny characters or spaces or anything else which is different from the other records, but everything seems to be in order. I doubt very much that this is a system app code problem as the code is working perfectly for all the other records...
Can anyone advise me on what else I can check.. really stuck on this one guys
I need to be able to prevent an invalid character from being entered into a sql 2000 databae on import from oracle.
In short, I need to exclude a certain character from being entered and need to be able to send an email which specifies that an attempt was made to enter this character, if the change was due to an insert or an update, the row to be affected in the target database, date and time info. Also the source of the data.
If this is not possible, is it viable to remove the character after insert and still send the email with the required info?

Hi SQL fans,I realized that I often encounter the same situation in a relationdatabase context, where I really don't know what to do. Here is anexample, where I have 2 tables as follow:__________________________________________ | PortfolioTitle|| Portfolio |+----------------------------------------++-----------------------------+ | tfolio_id (int)|| folio_id (int) |<<-PK----FK--| tfolio_idfolio (int)|| folio_name (varchar) | | tfolio_idtitle (int)|--FK----PK->>[ Titles]+-----------------------------+ | tfolio_weight(decimal(6,5)) |+-----------------------------------------+Note that I also have a "Titles" tables (hence the tfolio_idtitlelink).My problem is : When I update a portfolio, I must update all theassociated titles in it. That means that titles can be either removedfrom the portfolio (a folio does not support the title anymore), addedto it (a new title is supported by the folio) or simply updated (atitle stays in the portfolio, but has its weight changed)For example, if the portfolio #2 would contain :[ PortfolioTitle ]id | idFolio | idTitre | poids1 2 1 102 2 2 203 2 3 30and I must update the PortfolioTitle based on these values :idFolio | idTitre | poids2 2 202 3 352 4 40then I should1 ) remove the title #1 from the folio by deleting its entry in thePortfolioTitle table2 ) update the title #2 (weight from 30 to 35)3 ) add the title #4 to the folioFor now, the only way I've found to do this is delete all the entriesof the related folio (e.g.: DELETE TitrePortefeuille WHERE idFolio =2), and then insert new values for each entry based on the new givenvalues.Is there a way to better manage this by detecting which value has to beinserted/updated/deleted?And this applies to many situation :(If you need other examples, I can give you.thanks a lot!ibiza

im not sure wats going wrong because the record is not being added. Please help!!
Hi again, In ASP.net, is there any elegant way to handle a set of time inserts from a form when the 2nd time is past midnight? Specifically, I have a form with 2 textboxes on it (startTime and endTime) that are set up to accept time values (using AJAX MaskedEditExtender for formatting/validation - pretty cool). This data is posted to a sub that enters the data into a table (T_Details). However, I've noticed that the data inserted as part of the record (SQL field is smalldatetime) doesn't take into account the fact that a time value past 23:59:59 in the "endTime" textbox is a time on the next day - it simply rolls to an A.M. date for the same day as the date for the pre-midnight value from the "startTime" textbox. I'm sure that I can simply do some conditional coding and modify the date if necessary but is there a better way to do it? Thanks as always...this forum is a great resource
Hi, I'm inserting a few columns into my db (they all have a nvarchar(50) ).. but i noticed when i retrieve them out of the db, the length of the string always have some trailing white spaces behind them and such when I try to do stuff like dropdownlist.items.findbyvalue(), it normally fails.I did trace and before the string get into the db, they were teh right length. so I'm not sure where did I do things wrong? thanks

I have a table where table row gets updated multiple times(each column will be filled) based on telephone call in data.
Initially, I have implemented after insert trigger on ROW level thinking that the whole row is inserted into table will all column values at a time. But the issue is all columns are values are not filled at once, but observed that while telephone call in data, there are multiple updates to the row (i.e multiple updates in the sense - column data in row is updated step by step),
I thought to implement after update trigger , but when it comes to the performance will be decreased for each and every hit while row update.
I need to implement after update trigger that should be fired on column level instead of Row level to improve the performance?
'The value you entered is not consistent with the data type or length of the column'
when trying to enter data into a feild, the feild type is char and the length is 100 i'm entering text 3 words long but no where near a 100 characters long any one know why this is happening?
I'm trying to create a WHERE clause that will have different results depending on a parameter that is entered. For example, if you put in a number, it will only calculate the rows where the column ID matches that number. However, if you put in 0, which doesn't exist in that column ID, it will instead calculate all the data in the table.
So the below would be a very basic idea of what I'm trying to do, but I'm not sure how to do it with proper syntax.
Hi,I want to know the optimal solution, to find if all the data was entered. Lets say, Table A (date field) and for a given month, i need that all the days in the given month are present in the Table A. Right now i have different solutions, 1) a stored procedure which loops through all the days in the given month against a select statement on Table A2) a stored procedure, create a temp table which contains all the dates in the given month, and a single select statement using where condition (select * from.... where datefield not in (select * from...))I want to know what is the best solution of these two or any other solution.Thanks
