What is the equivalent of OracleBulkCopy in PostgreSQL?             

Are you talking about the PL/SQL "bulk collect into" feature?

If not, what exactly is "OracleBulkCopy" doing? Can you show some code examples?

Probably COPY: https://www.npgsql.org/doc/copy.html

Hi Again,



Following is the implementation that I have used using OracleBulkCopy wherein I have mapped the DB & data table columns [Highlighted in yellow]. But in the 'Text Copy' how can I specify these mappings.



public static void MYFunc (DataTable dt)

{

string error = string.Empty;

OracleConnection connection = CreateConnection();

connection.Open();

OracleBulkCopy bulkCopyRecords = new OracleBulkCopy(connection);

bulkCopyRecords.DestinationTableName = "EMPLOYEE ";

bulkCopyRecords.ColumnMappings.Add("EMPLID", "EMPLOYEE_ID");

bulkCopyRecords.ColumnMappings.Add("CATEGORY_ID", "CATEGORY_ID");

try

{

bulkCopyRecords.WriteToServer(dt);

}

catch (Exception ex)

{

error = ex.Source + " -> " + ex.Message + "<br /><br />" + ex.StackTrace + "<br />";

}

finally

{

DisconnectConnection(connection);

}

}



Thanks

This will be quite different in the PostgreSQL case.
Read the documentation on COPY.

You will have to rewrite your code.

That’s the question - What's the code that I need to rewrite the code in postgre?

Thanks
