is there a way to colspan and rowspan in plsql spool into .csv?

is it possible to rowspan and colspan on .csv using spool? Like how you use a rospan and colspan in html <table< tags

Solution

  • No, the CSV format does not support data points spanning multiple rows and columns.

    RFC 4180: Common Format and MIME Type for CSV Files defines a CSV as:

    This section documents the format that seems to be followed by most implementations:

    1. Each record is located on a separate line, delimited by a line break (CRLF). For example:

      aaa,bbb,ccc CRLF
zzz,yyy,xxx CRLF

    2. The last record in the file may or may not have an ending line break. For example:

      aaa,bbb,ccc CRLF
zzz,yyy,xxx

    3. There maybe an optional header line appearing as the first line of the file with the same format as normal record lines. This header will contain names corresponding to the fields in the file and should contain the same number of fields as the records in the rest of the file (the presence or absence of the header line should be indicated via the optional "header" parameter of this MIME type). For example:

      field_name,field_name,field_name CRLF
aaa,bbb,ccc CRLF
zzz,yyy,xxx CRLF

    4. Within the header and each record, there may be one or more fields, separated by commas. Each line should contain the same number of fields throughout the file. Spaces are considered part of a field and should not be ignored. The last field in the record must not be followed by a comma. For example:

      aaa,bbb,ccc

    5. Each field may or may not be enclosed in double quotes (however some programs, such as Microsoft Excel, do not use double quotes at all). If fields are not enclosed with double quotes, then double quotes may not appear inside the fields. For example:

      "aaa","bbb","ccc" CRLF
zzz,yyy,xxx

    6. Fields containing line breaks (CRLF), double quotes, and commas should be enclosed in double-quotes. For example:

      "aaa","b CRLF
bb","ccc" CRLF
zzz,yyy,xxx

    7. If double-quotes are used to enclose fields, then a double-quote appearing inside a field must be escaped by preceding it with another double quote. For example:

      "aaa","b""bb","ccc"

    There is no mention of implementing rowspan or colspan or even of the concept of fields spanning multiple rows or columns.
