![]() ![]() I am trying load the file into SQL Server 2012 using SSIS(SQL Server Data Tools 2012). The SQL Server connector is based on the Abstract Syntax Notation (ASN). ![]() Make a map of input cells to buffer columns, that would slow things down even more.Īnother argument that will be made is a valid one, but misses the point: Who changes CSV file layouts? They're (typically) constructed by computers, so they're not supposed to change. My Source File is () Pipe Delimited text file(.txt). Therefore, it is convinient to use external tables to load flat files into the. That's why it doesn't handle files with missing columns very well - it's not actually detecting the end-of-row delimiter like you'd think it was, that would add a smidgen of overhead, so they don't do it. Step 1 In order to attempt to parse the data contents of each csv flat file the file needed to be imported into a table in a raw unaltered format where each row in the flat file is loaded as a record or row in a single column table. As such, it's optimized to blow through the file and hammer contents into the square SSIS memory buffer The Flat File Source is supposed to perform fast (well - all the components are, but this is going to be the "unique" defense to this behaviour). ![]() I'll have to ask around a little about this - but I can guess as to the reasoning I'll get behind this behaviour: When using any other source, the column contents would follow the column headers. ![]()
