The extended ASCII characters (0x0080 - 0x00ff) are not supported. These comprise the ASCII control characters and the ASCII printable characters. Note: The built-in CSV driver handles hex-defined delimiter characters in the range 0x0000 - 0x007f only. Row_Number GSsource_order_id GScategory GSorder_dt GSship_dt GSstatus The following sample flat file rows use the GS character (hex value: 0x001d) as delimiter: Delimiters like these can be set up in the Connection Wizard, using their hex values with the "0x" syntax. Examples might come from the ASCII control character range, such as the "Start of Heading" (SOH) character or the "Group Separator" (GS) character. In some cases, you may find yourself confronted with files delimited by a non-printing character. The setup in the Connection Wizard Delimiter Options looks like this: Row_Number BELsource_order_id BELcategory BELorder_dt BELship_dt BELstatusĢ BEL2 BELOvernight BEL BELnull BELPending The following sample flat file rows use the bell character ('\a') as delimiter: Less common options are the "bell" character ('\a') and the vertical tab ('\v'), which are handled using their escapes as convenience sytnax. The most common of these, the tab escape ('\t') is handled as a standard choice due to its continued frequency. QuerySurge supports some of the C-style Escape characters as delimiters. The following sample flat file rows use the sequence as setup in the Connection Wizard Delimiter Options looks like this: As with all unconventional delimiters, a multicharacter delimiter is set up using the Other option in the Delimiter Options section of the QuerySurge Connection Wizard. QuerySurge's builtin flat file driver handles multicharacter delimiters.

In its "true" CSV format, our sample data looks like: Sample Data for this articleįor the examples in this article, we use some basic sales data. This article shows the setup for testing the data in flat files with nonstandard delimiters. While many (perhaps most) flat files follow the standard of using comma- or tab- delimiters, with frequency, users encounter files for data testing with QuerySurge that use unconventional delimiters. Flat files, despite being a venerable technology, are still in common use across countless Data Warehouse ETL/LT processes.
