Import CSV File Error : Column Value containing column delimiter

Question

I am trying to Import a Csv File into SQL SERVER using SSIS

Here\'s an example how data looks like

Student_Name,Student_DOB,Student_ID,Student_Notes         


        

Answer 1

If import CSV file is not a routine

1. Import CSV file in Excel
2. Search error rows with Excel rows filter and rewrite them
3. Save Excel file in TXT Tab delimited
4. Import TXT file with SSIS Else make a script that search comma in the Student Notes column range

Answer 2

In The Flat File Connection Manager. Make the File as only one column (DT_STR 8000)

Just add a script Component in the dataflowtask and Add Output Columns (Same as Example Shown)

in The script component split each row using the following Code:

\\Student_Name,Student_DOB,Student_ID,Student_Notes,Student_Gender,Student_Mother_Name

Dim strCells() as string = Row.Column0.Split(CChar(","))

Row.StudentName = strCells(0)
Row.StudentDOB = strCells(1)
Row.StudentID = strCells(2)
Row.StudentMother = strCells(strCells.Length - 1)
Row.StudentGender = strCells(strCells.Length - 2)

Dim strNotes as String = String.Empty

For int I = 3 To strCells.Length - 3

strNotes &= strCells(I)

Next

Row.StudentNotes = strNotes

it worked fine for me

Answer 3

A word of warning: I'm not a regular C# coder.

But anyway this code does the following:

It opens a file called C:\Input.TXT

It searches each line. If the line has more than 5 commas, it takes all the extra commas out of the third last field (notes)

It writes the result to C:\Output.TXT - that's the one you need to actually import

There are many improvements that could be made:

• Get file paths from connection managers
• Error handling
• An experienced C# programmer could probably do this in hlaf the code

Keep in mind your package will need write access to the appropriate folder

public void Main()
{
    // Search the file and remove extra commas from the third last field

    string sInputLine;
    string sOutputLine;
    string sDelimiter = ",";
    String[] sData;
    int iIndex;

    // open the file for read
    using (System.IO.FileStream inputStream = File.OpenRead("C:\\Input.txt"))
    {
        using (StreamReader inputReader = new StreamReader(inputStream))
        {
            // open the output file
            using (StreamWriter outputWriter = File.AppendText("C:\\Output.txt"))
            {
                // Read each line
                while (null != (sInputLine = inputReader.ReadLine()))
                {
                    // Grab each field out
                    sData = sInputLine.Split(sDelimiter[0]);
                    if (sData.Length <= 6)
                    {
                        // 6 or less fields - just echo it out
                        sOutputLine = sInputLine;
                    }
                    else
                    {
                        // line has more than 6 pieces 
                        // We assume all of the extra commas are in the notes field                                

                        // Put the first three fields together
                        sOutputLine =
                            sData[0] + sDelimiter +
                            sData[1] + sDelimiter +
                            sData[2] + sDelimiter;

                        // Put the middle notes fields together, excluding the delimiter
                        for (iIndex=3; iIndex <= sData.Length - 3; iIndex++)
                        {
                            sOutputLine = sOutputLine + sData[iIndex] + " ";
                        }

                        // Tack on the last two fields
                        sOutputLine = sOutputLine +
                            sDelimiter + sData[sData.Length - 2] +
                            sDelimiter + sData[sData.Length - 1];


                    }

                    // We've evaulted the correct line now write it out
                    outputWriter.WriteLine(sOutputLine);
                }
            }
        }
    }
