![]() ![]() SQL*Plus 12.2 has added a set markup csv option, and when you turn on text quoting ![]() sqlplus on the other hand has been around as long as Oracle has been and it is everywhere. It may be that the people who install and maintain database and ETL servers are just dinosaurs who don’t trust new stuff. ![]() I have not seen it used as a replacement for sqlplus and am not completely sure why. It has a robust set of output formats and is quite handy with CSV, both for exporting and for importing! Although it ships with the Oracle client, it may or may not be installed on your ETL server. It supports most of the cruft of sqlplus while also adding new stuff and many of the features of SqlDeveloper. SQLcl (SQL Developer Command Line) is a Java-based tool. That is not a viable solution to something you want to automate. These work well, but they require a person to execute them. You chan choose whether or not to quote and whether or not to include column headers. Toad and Sqldeveloper both have CSV format file output options. Generating CSVįrom an Oracle database there are tools we can use to generate a CSV output file. If the input file follows RFC4180, I suspect Oracle sqlldr will parse it just fine. When the input file does not comply, as for instance when a non-quoted string contains the delimiter, all bets are off. I did not go out of my way to torture it the way I did my split function, yet the only issues I’ve ever encountered with it had to do with funky non-ascii characters, which is only tangentially related to the CSV format in that it depends on an understood common or convertible character set. Sqlldr (and by extension external tables) support a text import option that should work for most honest CSV input files:įIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"' Yet it seems to work just fine, passing all of the test cases I can conjour to throw at it. The regular expression it employs is so ugly the comments outweigh the code ten to one. I have what I think is a complete solution for parsing CSV in the Oracle PL/SQL function split. ![]() Parsing a CSV file seems simple until you read all of the rules and sit down to try to do it. There is a semi-official standard for the format at RFC4180, but if you read it you will find it is fairly permissive about how you can quote fields that contain separators and even newlines.
