Flat File with random bad rows.

I have a text file that come from our client that is Column deliminated by ~ and row deliminated by {CR}{LF}.

There is a comment field that appearently is not cleaned up and has {CR}{LF} within the comment field.

I am new to SSIS and I'm wondering if there is a way to detect and correct the bad rows?

example file formet:

ORDERID~DATE~Comment~Address

1~2/3/2007~Some Comment~1234 oak st

2~2/3/2007~Some messed

up comment~345 oak st.

3~2/3/2007~Another comment~3214 asdf blvd.

Thank you.

You can use the Microsoft Visual Basic .NET RTrim function in a script run from the Script Component (configured as a transformation), to remove white space characters such as line feed and carriage return characters.

So the package data flow would include a Flat File Source connected to a Script Component. The output of the Script Component can then be sent to a destination or another transformation.

For information about the VB function, see "LTrim; RTrim; and Trim functions" at http://msdn2.microsoft.com/en-us/library/h9wz3dez(VS.71).aspx. For information about the Script Component, see "Extending the Data Flow with the Script Component" at http://msdn2.microsoft.com/en-us/library/ms136118.aspx.

How do you specify the line-feed character in the REPLACE function?

Try

\n

Generally, you use a \ character to escape special characters. \n indicates new line, \t indicates tab, etc.

Thanks John, that works great

If you enclose the escape character in quotes ("\n"), the expression will parse. For more information about using characters that require escape sequences in string literals, see "Literals (SSIS)" at http://msdn2.microsoft.com/en-us/library/ms141001.aspx.
