Body
I have minor improvements to jeb's clever "always" solution. Currently jeb's solution has the following issues: <ol> <li>If the leading path is enclosed in quotes, then the first output starts with ""</li> <li>If the trailing path is enclosed in quotes, then the last output ends with ""</li> <li>If any path contains harmless but non-functional consecutive "", then the output preserves the ""</li> <li>If var contains consecutive ;; delimiters then outputs ECHO is off</li> </ol> This solution fixes the minor issues, plus it uses 2 fewer substitutions. Also I eliminated the unnecessary repeated enabling/disabling delayed expansion within the loop. (Edit on 2011-10-30 simplified the ENDLOCAL logic) <pre><code>@echo off setlocal DisableDelayedExpansion set "var=%var:"=""%" set "var=%var:^=^^%" set "var=%var:&=^&%" set "var=%var:|=^|%" set "var=%var:<=^<%" set "var=%var:>=^>%" set "var=%var:;=^;^;%" set var=%var:""="% set "var=%var:"=""Q%" set "var=%var:;;="S"S%" set "var=%var:^;^;=;%" set "var=%var:""="%" setlocal EnableDelayedExpansion set "var=!var:"Q=!" for %%a in ("!var:"S"S=";"!") do ( if "!!"=="" endlocal if %%a neq "" echo %%~a ) </code></pre> If you want to see a blank line for each empty path resulting from consecutive ;; delimiters, then the last line of the FOR loop can simply read <code>echo(%%~a</code> instead. Or perhaps it would be more obvious to display empty paths as "" using: <code>if %%a=="" (echo "") else echo %%~a</code> The various empty path fixes work for jeb's simple solution as well. <h2>UPDATE: Here is a simple one-liner using JREPL.BAT</h2> You can use my <a href="http://www.dostips.com/forum/viewtopic.php?f=3&t=6044" rel="nofollow">JREPL.BAT regular expression text processing utility</a> to achieve a simple, very robust solution. JREPL.BAT is pure script (hybrid JScript/batch) that runs natively on any Windows machine from XP onward. <pre><code>jrepl "([^;\q]+|\q.*?(\q|$))+" $0 /x /jmatch /s path </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
