Insert Two Rows Into Two Tables At The Same Time From A Formview
Jul 31, 2007
I have a formview that uses a predefined dataset based on a cross table query. When the formview is in insert mode I need to insert the data into two seperate tables. Essentially I have tblPerson and tblAddress and my formview is capturing username, password, name, address line1, address line 2, etc. I presume I need to use a stored procedure to insert a row into tblPerson and then insert a row intp tblAddress. This is easy enough to do but the tables use RI and tblPerson has an imcremental primary key which needs to be innserted into a foreign key field in my address row. How do I do this? I'm using SQL Server.
Hello,I have 4 tables having Customer, Customer_personal_info, Customer_Financial_info, Customer_Other_infoIn this Customer table had a primary key CustomerID , related with every other table with fkey.I want to insert data into four tables using one form having TABs .I created class and storedProcedures to insert row for each table.How to execute all four classes using beginTrans-commitTrans-Rollback-EndTrans. Thanking you,
Can one of you help me with using a cursor that would insert only 100 rows at a time from source table 1 to target table 2. I am not able to loop beyond the first 100 rows.
Here is what I have till now:
CREATE procedure Insert100RowsAtaTime AS SET NOCOUNT ON
declare @Col1 int declare @Col2 char(9) DECLARE @RETURNVALUE int DECLARE @ERRORMESSAGETXT varchar(510) DECLARE @ERRORNUM int DECLARE @LOCALROWCOUNT int
declare Insert_Cur cursor local fast_forward FOR SELECT top 100 Col1,Col2 from Table1 WHERE Col1 not in ( SELECT Col1 /* Col1 is PK. This statement is used to prevent the same rows from being inserted in Table 2*/ from Table2)
set @RETURNVALUE = 0 set @ERRORNUM = 0
BEGIN
open Insert_Cur fetch NEXT from Insert_Cur into @Col1, @Col2 while (@@FETCH_STATUS = 0) insert into Table2 (Col1,Col2) select @Col1,@Col2
SELECT @ERRORNUM = @@ERROR, @LOCALROWCOUNT = @@ROWCOUNT IF @ERRORNUM = 0 BEGIN IF @LOCALROWCOUNT >= 1 BEGIN SELECT @RETURNVALUE = 0 END ELSE BEGIN SELECT @RETURNVALUE = 1 RAISERROR ('INSERT FAILS',16, 1) END END ELSE BEGIN SELECT @ERRORMESSAGETXT = description FROM [master].[dbo].[sysmessages] WHERE error = @@ERROR RAISERROR (@ERRORMESSAGETXT, 16, 1) SELECT @RETURNVALUE = 1 END
I want to Insert 10000 rows at a time and commit in sql server , Isthere a way to do it if the source tables have no id fields ?What would be the most efficient method?ThanksAjay
I have formview and want to get uniq id from SQL Server 2005 after it inserted. I think i should put some code in the event of oniteminserted, anybody have sample code Thanks Hu
Hello,I am trying to determine the best way to do the following. For simplicity we have two tables Master and Awards. These share a common pk UFID. Master contains columns (UFID, AccountName...) Awards contains columns (ID, UFID, AwardingAgency, Amount) When a user submits a new award in Formview I would like to populate the UFID automatically so that the user does not have to enter this each time. I am currently using the logged in username to select records for that user only. The value of this username matches Master.AccountName. Since I am hoping to use this same logic across many tables, I would appreciate any suggestions as to how best handle this.Thanks,Ken
i need to insert data into 2 tables. first in one, and the id of the register i just inserted is a field from the register in the other table (+ other data). inserting in this 2 tables should be invisible to the user so it has to be done automatically. the dumb way i guess would be using 2 ADODB.recordsets (rs,rs1). first insert in one store the id in a var (after rs.update, rs.movelast, var=rs.fields("id")) and after this inserting a register in the new recordset (rs1)
I m trying to INSERT a record to my Consultants table using sqldatasource and formview: here is my sqldatasource code: <asp:SqlDataSource ID="sqlDS1" runat="server" ConnectionString="<%$ ConnectionStrings:myDB %>"InsertCommand="INSERT INTO [Consultants] ([firstName],[lastName],[skillCategoryID],[resourceManagerID],[AMgroupID],[skillSet],[statusID],[location],[comments],[profile],[isAvailable],[dateModified],[focusID]) VALUES (@FNAME, @LASTNAME, 1, @RESOURCEMANAGERID, @AMGROUPID, @SKILLSET, @STATUSID, @LOCATION,@COMMENTS,@PROFILE,@ISAVAILABLE,getdate(),1)">
<InsertParameters> <asp:FormParameter FormField="txtFName" Name="FNAME" /> <%--other parameters--%></InsertParameters></asp:SqlDataSource> now in my formview i have this:<asp:FormView DefaultMode="Insert" ID="FormView1" runat="server" DataSourceID="sqlDS1" DataKeyNames="id"> <table border="0" cellspacing="5" cellpadding="0"><tr> <td class="blacktextbold">First Name:</td> <td class="blacktext"><asp:TextBox ID="txtFName" CssClass="txtfield" Width="200" runat="server" Text="<% #Bind('firstName')%>" /> <asp:RequiredFieldValidator ControlToValidate="txtFName" runat="server" ValidationGroup="gpInsert" ErrorMessage="Required Field" Display="Dynamic" CssClass="redtextsmallbold" /> </td></tr> </table> THE PROBLEM:no matter what i put the txtFName field its ALWAYS null and i get INSERT error as column firstName cant accept NULLany ideas? ur help would be appreciated
Guys, here is my scenario: I have 3 tables 1) Vendor 2) Service 3) Service Product Each vendor has the ability to have any number of services, all with any number of service products. How should I setup my page so I can edit/insert vendors, and tie a list of service products and services to them? My plan was to have a Formview with either a checkboxlist, or multilist (to select multiple items - but they don't work that way) and then store selected items in another table (each item selected with its own record) to hold onto the vendor id and tie it to a service id and a product id, but I was unsure how to do this. Any help would be greatly appreciated. FYI I am writing in VB.
I setup the databse and Visual Web Developer to use stored procedures when the insert command is used. The database also uses the field UserName that I pass using a SessionParameter within the InserParameter block from the Membership.GetUser.Username from the aspnet_ tables.
My difficulty is when using the "Formview" as the body to with which to insert (I wanted the design versatility of FormView) I get an error: "system.formatExpression: Input string was not in a correct format" when I leave the textboxes empty and invoke the insert command. I first assumed that the bound textboxes are not being converted correctly when left blank, so I used the ConvertEmptyStringToNull=True, with no success. I then coupled that with the Type=[correct format] still with the same error. Alas, my final attempt was to set defaults in the "ALTER PROCEDURE" within the stored procedure itself.
Dear All, i have a SqlDataSource with a simple select command(e.g. "select a,b,c from foo"). The insert command is a stored procedure and takes less parameters than there are columns in select statement (e.g. "insertFoo(a char(10))"). When used in combination with form view, i get "Procedure or function insertFoo has too many arguments specified" error. It seems that form view always posts all columns as parameter collection (breakpoint in formview_inserting event shows this) to insert command. Am I doing something wrong or is this by design? Is the only solution to manualy tweak parameters in formview_inserting event? TIA Jernej
I have an PL/SQL procedure @ Oracle database which extracts 10000 rows from a table and Now I have load all the 1000 rows into SQL 2005 tables.
I have extracted the data from oracle into DataAdapter/dataset , Now I want to load all the rows to SQL 2005 tables. Please help how I can load..
If I use insert statement everytime , it makes server busy and takes much time for 10000 inserts to complete(even using Procedure goes heavy since for every insert have to call this).
Is there any possibility that i can pass the REF Cursor / Dataset/dataAdapter into SQL stored so that inserts will have happen all together ??
i've read the transact-sql command, i known that the select command use to retrieve many fields from many tables with one command select * from table1,table2 yes, but i ' ve not seen the way to add,delete or update those fields from those tables with one command...
Is it possible? why? I don't have any idea , can u help me I want to know the sql commands , if it's possible
I have a form view that I am using to insert new data into a sql express database and would like to find a way to avoid attempting to insert a record if the key already exists. is there a way to do this with the formview insert command. Everything works great until I try to add a record with an already existing value in the unique key field, then it breaks.
I'm trying to get to grips with the formview control and have a problem regarding where an exception is raised if SQL server raises an error when an insert is taking place. I am new to both asp.net & c# I have put the following code in the SqlDataSource2_Inserted & Formview1_Inserted events as a way of determining where the exception is raised: if (e.ExceptionHandled){ string exceptionmessage = e.Exception.Message; lblStatus.Text = exceptionmessage;} These two events are the only one's that have the ExceptionHandled and Exception properties. I run the code with data that will raise a duplicate key error from SQL Server but the error is not being caught by either of these two handlers. All I get is a page that starts with Server Error in '/SourceCode' Application.
Violation of UNIQUE KEY constraint 'IX_reftblAntigens'. Cannot insert duplicate key in object 'reftblAntigens'.The statement has been terminated. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.Data.SqlClient.SqlException: Violation of UNIQUE KEY constraint 'IX_reftblAntigens'. Cannot insert duplicate key in object 'reftblAntigens'.The statement has been terminated.... Is there somewhere else I should be looking to handle this sort of thing? I thought using the databound controls would make life easier but I'm actually finding it more of a pain than coding everything myself.
I am trying to do the following: Insert n rows into A Table called EAItems. For each row that is inserted into EAItems I need to take that ItemID(PK) and insert a row into EAPackageItems. I'm inserting rows from a Table called EATemplateItems. So far I have something like this: (I have the PackageID already at the start of the query). INSERT INTO EAItems(Description, Recommendation, HeadingID)SELECT Description, Recommendation, HeadingIDFROM EATemplateItems WHERE EATemplateItems.TemplateID = @TemplateID INSERT INTO EAPackageItems(ItemID, PackageID) ....
I have no idea how to grab each ITemID as it's created, and then put it into the EAPackageItems right away.
I have a form to assign JOB SITES to previously created PROJECT. The JOB SITES appear in the DataList as it varies based on customer. It can be 3 to 50 JOB SITES per PROJECT. I have "PROJECT" table with all necessary fields for project information and "JOBSITES" table for job sites. I also created a new table called "PROJECTSITES" which has only 2 columns: "ProjectId" and "SiteId". What I am trying to do is to insert multiple rows into that "PROJECTSITES" table based on which checkbox was checked. The checkbox is located next to each site and I want to be able to select only the ones I need. Btw the Datalist is located inside of a formview and has it's own datasource which already distincts which JOBSITES to display. Sample: ProjectId - SiteId 1 - 5 1 - 9 1 - 16 1 - 18 1 - 20 1 - 27 1 - 31 ProjectId stays the same, only values for SiteId are being different. I hope I explaining it right. Do I have to use some sort of loop to go through the automatically populated DataList records and how do I make a multiple inserts to database table? We use SQL Server 2005 and VB for code behind. Please ask if I missed on some information. Thank you in advance.
I am using VS2005 (VB) to develop a PPC WM5.0 Program. And I am using SQLCE 3.0. My PPC Hardware is in 400MHz.
The question is when the program try to insert the first record into sdf database after each time the program started. It takes a long time. Does anyone know why and how can I fix it?
I will load the whole database into a dataset when the program start and do all the "Insert", "Update", "Delete" in this dataset and fill it into database after each action.
cn.Open() sda = New SqlCeDataAdapter(SQL, cn) 'SQL = Select * From Table scb = New SqlCeCommandBuilder(sda) sda.Update(dataset) cn.Close()
I check the sda.update(), it takes about 0.08s for filling one record into database normally. But:
1. Start the PPC Program
2. Load DB into dataset
3. Create a ONE new record in dataset
4. Fill back to DB
When I take this four steps everytime, the filling time is almost 1s or even more!
Actually, 0.08s is just a normal case. Sometimes, it still takes over 1s to filling back a dataset which only inserted one record when the program is running. (Even all inserted records are exactly the same in data jsut different in the integer key)
However, when I give up the dataset and using the following code:
cn.Open() Dim cmd As New SqlCeCommand(SQL, cn) ' I have build the insert SQL before (Insert Into Table values(XXXXXXXXXXXXXXX All field)
I found that it is still the same that the first inserted record takes more time, but just about 0.2s. And the normal insert time is around 0.02s. It is 4 times faster!!!
We need to select rows from the database that have been recently inserted/updated. We have a main primary table (COMMIT_TEST) and a second update table (COMMIT_TEST_UPDATE). The update table contains the primary key and a LAST_UPDATE field which is a datetime (to tell us when an update occurred). Triggers on the primary table are used to populate the update table.
If we insert or update the primary table in a transaction, we would expect that the datetime of the insert/update would be at the commit, however it seems that the insert/update statement is cached and getdate() is executed at the time of the cache instead of the commit. This causes problems as we select rows based on LAST_UPDATE and a commit may occur later but the earlier insert timestamp is saved to the database and we miss that update.
We would like to know if there is anyway to tell the SQL Server to not execute the function getdate() until the commit, or any other way to get the commit to create the correct timestamp.
We are using default isolation level. We have tried using getdate(), current_timestamp and even {fn Now()} with the same results. SQL Queries that reproduce the problem are provided below:
/* Different functions to get current timestamp all have been tested to produce the same results */ /* SELECT GETDATE() GO SELECT CURRENT_TIMESTAMP GO SELECT {fn Now()} GO */ /* Use these statements to delete the tables to allow recreate of the tables */ /* DROP TABLE COMMIT_TEST DROP TABLE COMMIT_TEST_UPDATE */ /* Create a primary table and an UPDATE table to store the date/time when the primary table is modified */ CREATE TABLE dbo.COMMIT_TEST (PKEY int PRIMARY KEY, timestamp) /* ROW_VERSION rowversion */ GO CREATE TABLE dbo.COMMIT_TEST_UPDATE (PKEY int PRIMARY KEY, LAST_UPDATE datetime, timestamp ) /* ROW_VERSION rowversion */ GO /* Use these statements to delete the triggers to allow reinsert */ /* drop trigger LOG_COMMIT_TEST_INSERT drop trigger LOG_COMMIT_TEST_UPDATE drop trigger LOG_COMMIT_TEST_DELETE */ /* Create insert, update and delete triggers */ create trigger LOG_COMMIT_TEST_INSERT on COMMIT_TEST for INSERT as begin declare @time datetime select @time = getdate()
insert into COMMIT_TEST_UPDATE (PKEY,LAST_UPDATE) select PKEY, getdate() from inserted end GO create trigger LOG_COMMIT_TEST_UPDATE on COMMIT_TEST for UPDATE as begin declare @time datetime select @time = getdate()
update COMMIT_TEST_UPDATE set LAST_UPDATE = getdate() from COMMIT_TEST_UPDATE, deleted, inserted where COMMIT_TEST_UPDATE.PKEY = deleted.PKEY end GO /* In our application deletes should never occur so we dont log when they get modified we just delete them from the UPDATE table */ create trigger LOG_COMMIT_TEST_DELETE on COMMIT_TEST for DELETE as begin if ( select count(*) from deleted ) > 0 begin delete COMMIT_TEST_UPDATE from COMMIT_TEST_UPDATE, deleted where COMMIT_TEST_UPDATE.PKEY = deleted.PKEY end end GO /* Delete any previous inserted record to avoid errors when inserting */ DELETE COMMIT_TEST WHERE PKEY = 1 GO /* What is the current date/time */ SELECT GETDATE() GO BEGIN TRANSACTION GO /* Insert a record into the primary table */ INSERT COMMIT_TEST (PKEY) VALUES (1) GO /* Simulate additional processing within this transaction */ WAITFOR DELAY '00:00:10' GO /* We expect at this point that the date is written to the database (or at least we need some way for this to happen) */ COMMIT TRANSACTION GO /* get the current date to show us what date/time should have been committed to the database */ SELECT GETDATE() GO /* Select results from the table we see that the timestamp is 10 seconds older than the commit, in other words it was evaluated at */ /* the insert statement, even though the row could not be read with a SELECT as it was uncommitted */ SELECT * FROM COMMIT_TEST GO SELECT * FROM COMMIT_TEST_UPDATE
Any help would be appreciated, we understand we could make changes to the application/database to approximate what we need, but all the solutions have identified suffer from possible performance issues, or could still lead to missing deals (assuming the commit time is larger than some artifical time window).
I have created several global temp tables to cache some intermediate results ... However, it seems that after a while those tables will be dropped by SQL Server 2005 automatically (I have not restarted the server and no drop table statement ever executed against those tables). Is this a feature by design? How to make those global temp tables persistence to next service restart?

Problem & Info:
I am bringing in an Excel file. I need to first strip out any non-detail rows such as the breaks you see with totals and what not. I should in the end have only detail rows left before I start moving them into my SQL Table. I'm not sure how to first strip this information out in SSIS specfically how down to the right component and how to actually code the component to do this based on my Excel file here: http://www.webfound.net/excelfile.xls
Then, I assume I just use a Flat File Source coponent or something to actually take the columns in the Excel and split into an OLE DB Datasource to shove each column into a corresponding column in my SQL Server Table. I have used a Flat File Source in the past to do so with a comma delimited txt file but never tried with an Excel.

I decided to change over from Microsoft Access Database file to the New SQLServerCe Compact edition. Although the reading of data from the database is greatly improved, the inserting of the new rows is extremely slow.
I was getting between 60 to 70 rows per sec using OLEDB and an Access Database but now only getting 14 to 27 rows per sec using SQLServerCe.
I have tried the below code changes and nothing seams to increase the speed, any help as I would prefer to use SQLServerCe as the database is much smaller and Im use to SQL Commands.

From what I know, when you execute an INSERT INTO table1 (field0) SELECT field0 FROM table 2 ORDER BY field0 the rows are inserted in whatever order the server engine thinks is better at that moment. Is it any way I can have field0 in table1 inserted in the order I need?
My problem is that I can not touch table1, it is used by a legacy application which I am not allowed to modify. I was thinking about creating a clustered index, adding an id field, etc, but I can not know how this will affect the front end application.
table1 and table2 have only a few hundred records.
table2 = CREATE TABLE [Test_FinalPlasma] ([nameID] [int] NOT NULL , [name] [varchar] (2000) NULL ) The update that is not giving the "good" order =

Unfortunately I can not order the [name] field after the update, because it looks something like

Currently, I'm using the following steps to migrate millions of records from Foxpro tables to SQL Server tables:
1. Transfer Foxpro records to .dat files and then bcp to SQL Server tables in a dummy database. All the SQL tables have the same columns as the Foxpro tables. 2. Manipulate the data in the SQL tables of the dummy database and save the manipulated data into the SQL tables of the real database where the tables may have different structure from the corresponding Foxpro tables.
I only know the following ways to import Foxpro data into SQL Server:
#1. Transfer Foxpro records to .dat files and then bcp to SQL Server tables #2. Transfer Foxpro records to .dat files and then Bulk Insert to SQL Server tables #3. DTS Foxpro records directly to SQL Server tables
I'm thinking whether the following choices will be better than the current way:
1st choice: Change step 1 to use #2 instead of #1 2nd choice: Change step 1 to use #3 instead of #1 3rd choice: Use #3 plus manipulating in DTS to replace step 1 and step 2
I am writing a query to return some production data. Basically i need to insert either 1 or 2 rows into a Table variable based on a decision as to does the production part make 1 or 2 items ( The Raw data does not allow for this it comes from a look up in my database)
I can retrieve all the source data i need easily but when i come to insert it into the table variable i need to insert 1 record if its a single part or 2 records if its a twin part. I know could use a cursor but im sure there has to be an easier way !
Below is the code i have at the moment
declare @startdate as datetime declare @enddate as datetime declare @Line as Integer DECLARE @count INT
set @startdate = '2015-01-01' set @enddate = '2015-01-31'
I am working on a SQL Server table designed by a partner company and cannot change the data structures. There is a table with a list of people available for calling out to a security system (keyholders).
From a web form, I need to allow my users to change the telephone calling order of the keyholders in the table.
The two important fields are AccountCode nVarChar and CallOrder nVarChar - where AccountCode + CallOrder must be unique.
As an example, the table may contain records with the following data..
1234, 1, Fred 1234, 2, Bert 1234, 3, Bob
If the user wants to make Bob the number 1 keyholder, Fred number 2 and Bert number 3 - what is the best practice for me to approach the update ?
There is a stored procedure that inserts a row into 'Vendors' table. Is it possible that two different calls to this sp happen at the same time and as a result, each sp inserts into the table its row at exactly the same time?
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.

I have a table of machine data that captures fault codes, time machine stopped and time machine started. I can easily calculate the downtime, but how do i take the last start time and subtract it from the next stop time (1 row from the next row) to get an up time. I need it to group by short date and fault as I intend to use Excel as a reporting tool and pulling in all data will not fit. What is the most efficient way? Thanks, Lee
