SQL Server :: Insert Large No Of Excel Sheet Rows Into Database Table?
Aug 17, 2010
I have an excel sheet that contains around 30,000 rows and 18 colmns. These no of rows and columns may increase in future. I need to read all these records from excel sheet and insert into a table in sql database. For reading the excel book I am using Oledbconnections. The possible solutions I have known as per my knowledge, to insert the data are
1. To insert one record at a time which makes 30,000 database hits. How will this affect the performance?
2. To use liked servers - bu this is not working for me.I do not have database permissions to use linked servers. So, the only option i have is the first one.

I do not have MS-office.This is in ASP.NET and C#.NETI am new to this concept.And friends there is a problem , i have 400 columns , which is not possible to insert into Open Office Excel , i need to insert other columns into new sheet

i have an aspx page which has a fileuploader and a button
initially i have to browse the file and after browsing the file i have to check the extension if the extension is xsl or xslx then only i have to enable the submit button
once the submit button is enabled i have to insert this data into the table
and i have to display the number of succesfully inserted rows and no of unsuccessfull insertions .
success and failure is dependent on the mismatch of the datatype between the excel sheet and the database column

i need to insert multiple rows at a time into database table(sqlserver) from datatable or gridview. Actually iam looping through the rows of gridview and inserting each row. Is there any method to insert entire table of rows at a time into database table. Both datatable columns and database table coulmns are similar.
I had task in my project to export grid view rows to excel sheet I serached and I had code and I did it but this class export only current page from grid view so I want also to export all gridview rows.
Class:
using System; using System.Data; using System.Configuration; using System.IO; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Web.UI.HtmlControls;.........

I work with Visual studio 2005 and Sql server data base. I extract 1 million rows from a database and I put the rows in a Sql table. With a simple direct extraction, in a few minutes I complete the operation:
Dim cmd As New SqlCommand(query, cnSql) cmd.ExecuteNonQuery() cmd.Dispose().
But, if I must select and modify some fields between extraction and introduction, it takes a lot of time! I work in this way. I extract rows from Dbase, Table1, and I put all into a Collection using dataReader:
Dim cmd As New SqlCommand(query, cnSql) Dim coll As New Collection coll.Clear() Dim dr As SqlDataReader = cmd.ExecuteReader() I replace some fields with the string "YES". Dim toRepl As String = "" If dr.HasRows Then Do While dr.Read toRepl = dr(5).ToString If Len(toRepl) <= 3 Then ToRepl = "YES" collPrel.Add(dr(0).ToString) collPrel.Add(dr(1).ToString) .................. .............. collPrel.Add(toRepl) collCount = collCount + 1 Loop End If dr.Close() cmd.Dispose() Now, I insert all into a SQL Table2: Dim a As String = "", b As String = "", c As String = "" etc. For i = 1 To collPrel.Count Step 6 a = collPrel.Item(i).ToString b = collPrel.Item(i + 1).ToString .............. ............... f = collPrel.Item(i + 5).ToString queryIns = "INSERT INTO Tab (name, adress, etc) VALUES ('" & a & "', '" & b & "', '" & c & "', etc. ) Dim cmdIns As New SqlCommand(queryIns, cnSql) cmdIns.CommandTimeout = 600 cmdIns.ExecuteNonQuery() cmdIns.Dispose() Next
This way to work goes right but it is necessary a lot of time for completing the operation.
i have made a connection and retrieve the data from the excel sheet. however when i run a query to update or insert some data into excel sheet it will generate an error "Cannot expand named range"
