Populating SQL Database With Something Similar To Access's Dropdown Lookup Field.
Sep 5, 2007
I am using two tables, courses and video with a one to many relationship with the videos table being the many. How do I populate the courseID in the video table with the corresponding courseID from the courses table using a combination of Formview & Gridview or two Gridviews, or a dropdown field populated with the course name and courseID in a Form or details view.This is a simple task in Access accomplished using a dropdown list to select the correct video.
Say I want to lookup a value in another dataset, but there is a grouping that requires you to know what the values for each level is in order to get to the correct detail record. Can you still use the lookup function with more than one field to compare against? So for example
Department \___SalesPerson \___Measure
I want to be able to add a new row at the Measure level, but lookup each field from another dataset. In order to do that I will need the Department AND SalesPerson values to do the lookup, but I dont think the Lookup function will let us do that will.
I have just started to look at SQL and have a theory question that I could apply to a test I want to run. I have some legacy data from a previous project and the database was not designed properly (in my opinion). They have ONE field to capture City and State information. All the data is formatted City, State .
Does SQL have commands that can look at data in a field, strip out info before and info after a comma and then write that to other fields?
So, I would like to normalize this to take the data in a field called CityState and parse it, trim it and then populate two new fields 1) City and 2) State.
I have 2 databases: one for our intranet & another for our internet website.In the intranet database, we have a table called "Clients". A new client can be added in one of 2 ways:
1) One of our employees manually adds the client via the intranet 2) A new customer subscribes to our services via our website, thus becoming a new "client" (when subscribing online, we also add a record to an "Accounts" table located in our internet website database, but we'd also like to add a record to our intranet's Clients table as well).
In the client table is a field called "CreatedBy" which expects the UserId of whoever created the account. Again, this UserId can belong to either an employee via the intranet or a new customer via our internet website. how do I distinguish where the UserId in the dbo.Clients.CreatedBy field is coming from?
My 1st thought was to append a negative to the CreatedBy UserId# if it came from a customer via the website, but that just seemed too quirky (i.e. if an employee added a client and his UserId was '10', the Clients.CreatedBy would be '10'. If a customer subscribed via the website, the Clients.CreatedBy would be '-10'. Where customers can once again sign up online. So, I need a way to keep these databases separate but keep track of which db a user's coming from when we create a new Client record.
I'm a bit stumped at this. I have done this before a bunch of times. The difference is that this time I have two rectangles in the footer. For the each, the visibility is set to an expression which checks whether the page is page 1 or 2. If it is 1, the first rectangle is visible, if 2, the second. When I reference the hidden fields on the main area of the report via ReportItems, they come through fine on the first rectangle, but are invisible on the second. I've tried the same exact fields and every time they are visible in rectangle1, and invisible in rectangle2. What is going on here???
I am not sure If I can do this with a lookup, but what I would like todo is perhaps use lookup to retrieve a control date from anunassociated table to control what date is entered in another table.For example :the main table , table 1 has many entries with a field called date_enter which is the date the record was entered.table 2 has a control_dateIf the date entered in table 1 is less than or = to the control date wewant to give the user a error message.I am thinking of using display only field and lookup to set itWould need to have the date value from the control table available tothe active table of table 1 when entering the the date_enter.However as there is no join field between the two tables am not surehow to do it. Was thinking might have to add a key field that wasallways null and in the BEFORE EDITADD EDITUPDATE section set it sothat the key would be nullAm using Informix 5 , Any help would be apprecia
I have a combo box where users select the customer name and can eithergo to the customer's info or open a list of the customer's orders.The RowSource for the combo box was a simple pass-through query:SELECT DISTINCT [Customer ID], [Company Name], [contact name],City,Region FROM Customers ORDER BY Customers.[Company Name];This was working fine until a couple of weeks ago. Now wheneversomeone has the form open, this statement locks the entire Customerstable.I thought a pass-through query was read-only, so how does this do atable lock?I changed the code to an unbound rowsource that asks for input of thefirst few characters first, then uses this SQL statement as therowsource:SELECT [Customer ID], [Company Name], [contact name],City, Region Fromdbo_Customers WHERE [Company Name] like '" & txtInput & "*' ORDER BY[Company Name];This helps, but if someone types only one letter, it could still bepulling a few thousand records and cause a table lock.What is the best way to populate a large combo box? I have too muchdata for the ADODB recordset to use the .AddItem methodI was trying to figure out how to use an ADODB connection, so that Ican make it read-only to eliminate the locking, but I'm striking outon my own.Any ideas would be appreciated.Roy(Using Access 2003 MDB with SQL Server 2000 back end)
There are two separate SQL Server databases involved that reside on two different servers. One of the depts within our building wants to have building permit data imported from Permit Database on Server "A" to their own database on Server "B".
I dont think this will be an overly complicated process. There are only a few fields they want populated (5 or 6 tops). This will have to be ran every weeknight via some sort of scheduled task in Windows or SQL.
I was just interested in seeing if anyone has had prior experience working on data transfer like this. I would like to know what would be the best and most efficient way to approach this.
Dear Friends, I want your help to know the best way to cache the data of a dropdownbox returned by a SQL Query.(SELECT FIELD FROM DBO.TABLE) This data returned by database is used in more than one dropdown on multiple pages. I want to cache only the dropdown control, not the entire page. Which is the best way to do it? The data isn't refreshed often, probably once per month. Could you tell me the best way? THANKS
I have a table that I am basically reduplicating a couple of times for each part of this database that I want to create.Each table basically has the same data: The tables will be called motherTable, fatherTable, sonTable, daughterTable and so on.I am pretty much using the following in each column: UserID, MotherID(or FatherID or SonID, etc., etc. and so on for each unique table), FirstName, LastName, MiddleName, BirthPlace, Photo, Age.I don't see an option to copy a table and just modify the second ID part and rename that table accordingly.How can I make this an easier way of creating these similar tables without retyping all these columns over and over again?Thanks in advance.
I have a table where I want to populate it with data (certain fields) from another table. But I only want to populate the table if there is data in a certain field in the table I wish to get the data from.
How exactly would I do this test? Would an I have to perform an IF statement to test if the field contains a value first?
Can anyone help with the proper syntax to use to populate a JavaScript array using values from an SQL database. I tried doing the following with no results:
Hello Folks I am a total new boy to Visual Web Developer and am struggling to implement a lookup field in the SQL Server Express that ships with it. I am trying to find the equivelent of using the lookup wizard in MS Access. So in Access I can select the lookup wizard from the drop down list of datatypes and refer to another table of standing data. Once configured the tables contents appear as a drop down list in the field of the master table. So how do I create a table in SQL Server 2005 that uses another table to give a drop down list in one of its fields? I have found some excellent tutorials and books but none of them seem to drill down to this level of table design, can anyone recommend any books that do? Thanks Bradley
I'm doing a data conversion with one of my fields (SUMDWK) from one of the tables that will be used in a merge join. With the new, converted field, I do a look up. From this look up, I want to take a new field FiscalWeekOfYear, and replace the original field, SUMDWK. This is necessary because SUMDWK is one of the sorted fields. In the look up, it is not possible to change the Output Alias. Does anybody know a way around this? Thanks.
I'm using DTS to import data from an Access memo field into a SQL Server ntext field. DTS is only importing the first 255 characters of the memo field and truncating the rest.I'd appreciate any insights into what may be causing this problem, and what I can do about it.Thanks in advance for any help!
Hi I have to populate some datas from sql server database and display it directly in a CSV Format or CSV file. When i run the project it should provide me an option to whether open or save or cancel the file. when i click open it should be opened and be viewed in a excel sheet in CSV format and when i click save it should ask the destination folder and should be saved there in CSV format and when i click cancel it should be cancelled and the application should be closed. pls note that all these actions should happen in the same browser and should not be redirected to anyother page. Can anybody give me the detailed description and code in Asp.Net using C# .It's very Urgent. RegardsVijay.
I'm importing an Access database to SQL Server 2000. The issue I ran into is pretty frustrating... All Memo fields that get copied over (as Text fields) appear to be fine and visible in SQL Server Enterprise Manager... except when I display them on the web via ASP - everything is blank (no content at all).
I didn't have that problem with Access, so I ruled out the possibility that there's something wrong with the original data.
Is this some sort of an encoding problem that arose during database import? I would appreciate any pointers.
i've a reasonable amount of experience with MS Access and less experience with SQL Server. I've just written an .NET application that uses an SQL Server database. I need to collate lots of data from around the company in the simplest way, that can then be loaded into the SQL Server database.
I decided to collect the info in Excel because that's what most people know best and is the quickest to use. The idea being i could just copy and paste the records directly into the SQL Server database table (in the same format) using the SQL Server Management Studio, for example.
Trouble is, i have a problem with line feed characters. If an Excel cell contains a chunk of text with line breaks (Chr(10) or Chr(13)) then the copy'n'paste doesn't work - only the text up to the first line break is pasted into the SQL Server database cell. The rest is not pasted for some reason.
I've tried with MS Access too, copying and pasting the contents of a memo field into SQL Server database, but with exactly the same problem. I've tried with 'text' or 'varchar' SQL Server database field formats.
Since i've no experience of using different types of databases interacting together, can someone suggest the simplest way of transferring the data without getting this problem with the line feeds? I don't want to spend hours writing scripts/programs when it's just this linefeed problem that is preventing the whole lot just being cut'n'pasted in 5 seconds!
Can anyone point me any solution how to export a MEMO field from an Access database to a TEXT field from an MS SQL Server 2000. The import export tool from SQL server doesn't import these fields if they are very large - around 9000 characters.
I have multiple web databases for storefront orders as linked servers on SQL Server 2008 R2. I need to organize the data for these orders into a structure that can be imported into my ERP application db frequently either on demand or periodically during the day. We are essentially trying to make the manual order entry process automated. My thought was to get the data into views that resemble the schema of the order table in my application db and then schedule a stored procedure with sql jobs or a load routine from within the ERP application that would insert data from the view into the order table.
have an excel file which contains lots of sheets. Some of them are named as DW-<day>-<month> (for e.g; DW-1-July). Like this I have sheets for the whole month. I have other sheets too with a different name. I would like to import data from these sheets only (DW ones). Upon my research I have found that this can be achieved via For Each Loop Container.
We are using lookup transformation in SSIS 2012. The lookup transformation queries a table with two date columns. When we hover the mouse over the two columns in the 'columns' tab of the lookup transformation editor, the two columns show as DT_WSTR instead of DT_DBDATE. This causes the SSIS package to fail due to data type mismatch.A similar abandoned thread is available at: URL....
We did some "at scale" fuzzy lookup tests today and were rather disappointed with the performance. I'm wanting to know your experience so I can set my performance expectations appropriately.
We were doing a fuzzy lookup against a lookup table with 25 million rows. Each row has 11 columns used in the fuzzy lookup, each between 10-100 chars. We set CopyReferenceTable=0 and MatchIndexOptions=GenerateAndPersistNewIndex and WarmCaches=true. It took about 60 minutes to build that index table, during which, dtexec got up to 4.5GB memory usage. (Is there a way to tell what % of the index table got cached in memory? Memory kept rising as each "Finished building X% of fuzzy index" progress event scrolled by all the way up to 100% progress when it peaked at 4.5GB.) The MaxMemoryUsage setting we left blank so it would use as much as possible on this 64-bit box with 16GB of memory (but only about 4GB was available for SSIS).
After it got done building the index table, it started flowing data through the pipeline. We saw the first buffer of ~9,000 rows get passed from the source to the fuzzy lookup transform. Six hours later it had not finished doing the fuzzy lookup on that first buffer!!! Running profiler showed us it was firing off lots of singelton SQL queries doing lookups as expected. So it was making progress, just very, very slowly.
We had set MinSimilarity=0.45 and Exhaustive=False. Those seemed to be reasonable settings for smaller datasets.
Does that performance seem inline with expectations? Any thoughts to improve performance?
I'm working with an existing package that uses the fuzzy lookup transform. The package is currently working; however, I need to add some columns to the lookup columns from the reference table that is being used.
It seems that I am hitting a memory threshold of some sort, as when I add 3 or 4 columns, the package works, but when I add 5 columns, the fuzzy lookup transform fails pre-execute:
Pre-Execute Taking a snapshot of the reference table Taking a snapshot of the reference table Building Fuzzy Match Index component "Fuzzy Lookup Existing Member" (8351) failed the pre-execute phase and returned error code 0x8007007A.
These errors occur regardless of what columns I am attempting to add to the lookup list.
I have tried setting the MaxMemoryUsage custom property of the transform to 0, and to explicit values that should be much more than enough to hold the fuzzy match index (the reference table is only about 3000 rows, and the entire table is stored in less than 2MB of disk space.
Hi everyone I've built an HttpModule and hooked into the Application_AuthorizeRequest to do some URL Rewriting. Basically what I'm doing is grabbing the URL such as www.mysite.com/about/, then doing a database lookup on the path (/about/) to see if I have a corresponding record for that string, and then rewriting the URL if a result is found (to something like www.mysite.com/About.aspx?id=1). My problem is that I am getting the following intermittent SQL error: An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) Whenever it happens I can hit refresh straight away and it will work fine. It also happens each time I upload a new web.config to my server. Any help would be appreciated! Thank you
We have been asked to look into using stored procedures with SQL Server 7.0 as a way to speed up a clients site. 99% of all the articles I have read along with all the books all say Stored Procedure should be used whenever possible as opposed to putting the SQL in your ASP script. However one of my colleagues has been speaking to Microsoft and they said that that they were surprised that our client wanted to use Stored Procedures as this was the old method of database access and that now he should really consider using COM objects for data access as itis much faster. Has anyone got any views on this or know of any good aticles regarding this matter ?
Actually this is in regard to SCD Type 2 Dimension, Scenario is like that I am moving Fact table from some old source and I have dimensionA description value in fact which I want to replace with appropriate id from Dimension Table and that Dimension table is SCD Type 2 based on StartDate and EndDate and Fact Table doesn't contains direct date value rather there is timeId in Fact so to update the value in Fact table I have to Join Time Dimension table and other Dimension Table to replace fact Description with proper Id.
I am doing a lookup that requires mapping 2 columns in the column mapping section. When I do this, I get the error "Row yielded no match during lookup" . The SQL that I captured in SQL profiler does find the record when I run it in Management Studio. I have already tried trimming everything to no avail.
Why is this happening?
I tried enabling memory restrictions but then I my package hangs and I get a SQLDUMPER_ERRORLOG.log file with the following logged:
