ASP.NET insertion and joining data between tables

Posted By:      Posted Date: September 01, 2010    Points: 0   Category :ASP.Net
I have the following tables:1.) PRODUCT_INFORMATION2.) CUSTOMERS3.) DISTRIBUTORS4.) PRODUCT_NAME5.) CONTROLLEREach table has a primary key assigned. The customers table has an ID column and a CUSTOMER_NAME column with unique index property set to avoid any duplication. How do I insert values in the product_information table that has a foreign key column from the CUSTOMERS table if we insert a value in the CUSTOMER_NAME field of the CUSTOMERS table. I want to know how can I create a join between all the tables so that when I insert values in individual tables they are joined with a serial number column in the PRODUCT_INFORMATION  table?Please suggest!!

If you need to search your entire database for specific data, this query will come in handy.

So when a client needs a custom report or some sort of custom development using Great Plains, most of the time I will have to track down the data in the system by running this query and find the table(s) it is in.

Unable to prepare the SSIS bulk insert for data insertion

Hi,   I am using SQL Server Destinations in my data flow tasks. I'm running this package in the server until i encountered this error:   OnError,,,LOAD AND UPDATE Dimension Tables,,,10/24/2007 1:22:23 PM,10/24/2007 1:22:23 PM,-1071636367,0x,Unable to prepare the SSIS bulk insert for data insertion.

SQL ServerDestination error - Unable to prepare the SSIS bulk insert for data insertion.

Having searched the forum, this one clearly has form... However beyond assisting those who have fallen at the first hurdle (i.e. forgetting/not knowing that they cannot execute the package remotely to the instance of SQL Server into which they are inserting), the issues raised by others have not been addressed. Thus I am bringing nothing new to the table here - just providing an executive summary of problems which others have run into, written about, but not received answers for.   First the complete error: Description: Unable to prepare the SSIS bulk insert for data insertion.  End Error  Error: 2008-01-15 04:55:27.58     Code: 0xC004701A     Source: <xxx> DTS.Pipeline     Description: component "<xxx> failed the pre-execute phase and returned error code 0xC0202071.  End Error  DTExec: The package execution returned DTSER_FAILURE (1).  Started:  4:53:34 AM  Finished: 5:00:00 AM  Elapsed:  385.384 seconds.  The package execution failed.  The step failed.   Important points It mostly works - It produces no error more than 9 times out of 10. It fails on random dataflows - My package has several dataflows, (mostly) executing concurrently. Where the error occurs it does not do so on the same dataflow each time: on one run it'll fail on dataflow A whilst B,C,D and E succeed, then A-E will all succeed (and continue doing so for the next ten runs thereafter), and

XSL Lookup to another List in a View. Joining in data from another List. xsl:value-of select=

I've been able to create a DataView with data joined from two SP Lists. I did this using SPD, a linked Source, and doing joined subviews.  The technique works nicely, but I have to create my DataView from scratch.As an alternative, I took an existing AllItems View in SPD, converted it to XSL, and was able to add a column from another List as follows:   <TD Class="{$IDA1VDGH}" style="width: 62px; height: 23px"><xsl:value-of select="/dsQueryResponse/Master/Rows/Row/@Lastname" />The problem is, it reports the column for the first row everytime. I'm new to XSL and was wondering..    using XSL, and preserving all the original columns already in the View, is there anyway to make the added column smarter, maybe with a filter?I noticed in my working example, I have this filter (I guess where the subview join magic is)            [@Title = $dvt_ParentRow/@Key] which does not resolve syntax:I tried this, but it does not work, only finding one match, and it also seems to get set for the entire Dataview and not just the column.     [../../../Master/Rows/Row/@Title = @Key] I guess I'm looking either for the SPD steps, or XSL code for adding a single column from another list, joined in by a column in both lists.Thanks for any help or information.

Import a flat file with combined data into separate SQL tables using SSIS

I have a flat text file (comma delimited) that is essentially multiple files, each with its own format, combined into one file. The file is coming from an external software vendor so unfortunately we don't have much choice but to work with what we are receiving. Here is an example of what the file could look like: Customer Data CustID,FName,LName,PhNum,Email 12345,John,Smith,,jsmith@gmail.com 12346,Jane,Doe,8001111111,jdoe@hotmail.com Customer Plan CustID,PlanType,PlanName,PlanStart 12345,0,Plan1,01/01/2010 12345,2,PlanVis,01/01/2010 12346,3,PlanLf,04/01/2010 12346,0,Plan1,01/01/2010 Customer Payment CustID,LastPayment,Amount 12345,09/01/2010,100.00 12346,05/01/2010,50.00 There is an empty line between each 'section' of data. I adapted a VB script I found online that can take the incoming file and save off each section as its own file so that each one can be separately imported, but this seems inefficient. I'm really new to SSIS in general, but it seems like it shouldn't be that difficult to take the data, split it where there is an empty line, and then import each section into the appropriate SQL table. Any ideas would be most welcome. Thanks!

for ajax data insertion in page what is faster than innerHTML ?

I m doing an ajax work where web service will return data and on client side and I am creating html table with data. I am using var (to hold string of generated html code), do string concatinations to generate table, tr and td tags and put data in it. Than I put this html table with data into a div using innerHTML. Please note I am applying inline css in this dynamic html code. The issue I am facing is web service will return a huge amount of data. What I tested is even on local machine it took about 10-12 minutes to process (concatinating, creating tags putting data in table, applying css) 10000 rows. Stored procedure just take 3-4 seconds in returning data. Please guide me how this inbrowser processing time can be reduced ? I am doing it for speed in some wrong way ? Or is there some technique for it or some method faster than innerHTML and string concatinations ? thanks
