i have a small website where users upload excel sheet and is stored in db. the sheets uploaded have a heading in A1:D then column names and then the data. i would like to skip the heading in A1:D and start importing from there

ive tried to copy what my sheet looks like:
Report for March 2019				
Task    Caption   Start Date	
19139   GP        01/11/2017		

i want to skip the heading 'Report for March 2019'

i am using sqlbulk copy and oledb and i have set HDR=Yes in connection string

What I have tried:

//declare destination table
        string ssqltable = "mytab";
        // make sure your sheet name is correct, here sheet name is sheet1, so you can change your sheet name if have different
        string myexceldataquery = "Select * FROM [Details$])";
        try
        {
            //create our connection strings
            string sexcelconnectionstring = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + excelfilepath + ";Extended Properties=" + "\"excel 12.0;hdr=yes;\"";

            string sclearsql = "TRUNCATE TABLE " + ssqltable;
            SqlConnection sqlconn = new SqlConnection(strConnString);
            SqlCommand sqlcmd = new SqlCommand(sclearsql, sqlconn);
            sqlconn.Open();
            sqlcmd.ExecuteNonQuery();

            //series of commands to bulk copy data from the excel file into our sql table
            OleDbConnection oledbconn = new OleDbConnection(sexcelconnectionstring);
            OleDbCommand oledbcmd = new OleDbCommand(myexceldataquery, oledbconn);
            oledbconn.Open();
            OleDbDataReader dr = oledbcmd.ExecuteReader();




            SqlBulkCopy bulkcopy = new SqlBulkCopy(strConnString);
            bulkcopy.DestinationTableName = ssqltable;
            //Mapping Table column    

            bulkcopy.ColumnMappings.Add("Task", "[Task]");
            bulkcopy.ColumnMappings.Add("Caption", "[Caption]");
            bulkcopy.ColumnMappings.Add("Start Date", "[Start_Date]");



            {
                bulkcopy.WriteToServer(dr);

            }
            oledbconn.Close();
            sqlconn.Close();

You're very welcome.
Your select statment has to provide the range of rows/columns to retrieve, not just the starting cell.

Something like SELECT * FROM [Details$A2:C3]

hi , i get the following error 'Syntax error in FROM clause.' and the number of rows in my sheets vary
Member 14183767 23-Apr-19 4:00am    
Hi Thank you it works! i had a bracket that was causing the syntax error
Try doing a read on the data reader before passing it to WriteToServer.

If WriteToServer doesn't "reposition" (most "stream readers" don't), then bulk copy should start on the second record.

OleDbDataReader dr = oledbcmd.ExecuteReader();
dr.Read();
...
