![]() ![]() When SSIS processes the first row of data, it’s going to get to the end of that row still expecting to find a pipe delimiter to indicate the end of that field. With a file like this, SSIS will continue to consume data for each field until it find the specified field delimiter – even if that means that the data is “gobbled up” from the next line in the file! Let’s assume that the outputs on my Flat File Source component define 11 fields (the largest number of fields found in this file snippet). This type of format where delimiters are simply left off when values at the end of the row are missing or NULL is, unfortunately, a relative common event that ETL developers must address. You can see that we’re not only missing the data but the delimiters as well, which is the root of the problem. As shown, the rows in the pipe-delimited file can have as few as seven and as many as eleven columns.Īlthough you and I can look at this file and interpret its meaning, previous versions of SSIS cannot (see note below regarding SSIS in SQL Server 2012). ![]() In this small sample file, you can see that we are dealing with medical data with an inconsistent format. Frequently I am asked how to properly use SQL Server Integration Services to handle ragged flat files, an example of which is shown below. ![]()
