We are getting the CSV file and we need to load this file into the SQL server table. There are multiple ways to load in the SSIS.
In this
demo, we will see how we will load the CSV file using the script task.
Below is the file.
We need to load it into the below table.
Let’s how to load this file.
Taking Script task.
In the
script task we are writing the below code.
public void Main() { try { // TODO: Add your code here char[] delimiters = new char[] { ',' }; //CSV file with comma separated DataTable dt = new DataTable(); using (StreamReader reader = new StreamReader("H:\\SSIS1\\Source\\Sales.csv")) //Reading the CSV file { string[] headers =
reader.ReadLine().Split(','); // Adding the Header into
the data table foreach (string header in headers) {
dt.Columns.Add(header); } dt.Columns.Add("Created_Date"); //Adding Created_Date column in the header dt.Columns.Add("Created_by"); // Adding created_by column in the header while (!reader.EndOfStream) { string[] rows =
reader.ReadLine().Split(','); DataRow dr = dt.NewRow(); for (int i = 0; i <
headers.Length; i++) { dr[i] = rows[i]; } dr["Created_date"] = DateTime.Now; //Adding Created_Date dr["created_by"] = "Bagesh"; //Adding Created_by dt.Rows.Add(dr); } } // creating connection to the data base string connection = "Data
Source=BAGESH-PC\\BAGESHDB;database=Test;integrated Security=SSPI;"; SqlConnection con = new SqlConnection(connection); //create object of
SqlBulkCopy which help to insert SqlBulkCopy obj = new SqlBulkCopy(con); //assign Destination table
name obj.DestinationTableName = "sales_Stg"; //Mapping the Source column
with destination column. //Keep in mind we need to
provide the correct mapping otherwise it will throw an error obj.ColumnMappings.Add("SalesOrderNumber", "SalesOrderNumber"); obj.ColumnMappings.Add("SalesAmount", "SalesAmount"); obj.ColumnMappings.Add("UnitPrice", "UnitPrice"); obj.ColumnMappings.Add("ExtendedAmount", "ExtendedAmount"); obj.ColumnMappings.Add("TaxAmt", "TaxAmt"); obj.ColumnMappings.Add("Created_Date", "Created_Date"); obj.ColumnMappings.Add("created_by", "created_by"); //Opining the connection con.Open(); //insert bulk Records into
DataBase. obj.WriteToServer(dt); //Closing the conntion con.Close(); Dts.TaskResult = (int)ScriptResults.Success; } //If any error comes logging
that error catch (Exception ex) { Dts.Events.FireError(0, "Fire Error", "An error occurred:
" +
ex.Message.ToString(), "", 0); Dts.TaskResult = (int)ScriptResults.Failure; } } |
Build and
close the script window and click ok.
Now our
package is ready to run.
