[Mapserver-users] Expression parser error

[Leah Roderman]

I'm curious about a msyyparse() error that is clogging my mapserv.out log. Here's the offending layer lifted straight from my mapfile:


LAYER
  NAME "roads"
  DATA tgr06001lkA
  STATUS DEFAULT
  TYPE LINE
  CLASSITEM "ZIPL"
  CLASS
    EXPRESSION ([ZIPL] > 94600 AND [ZIPL] < 94700)
    COLOR 0 0 0
  END # class
END # layer


>From the browser, the layer displays and Mapserver doesn't seem to hang. I went digging around the archives and tried variations on the expression line above, with differing display results but was unable to eliminate the logfile error (except of course by removing the layer in question altogether).

displays correctly :([ZIPL] > 94600 AND [ZIPL] < 94700)
displays correctly: (([ZIPL] > 94600) AND ([ZIPL] < 94700))
displays nothing: ([ZIPL] > 94600) AND ([ZIPL] < 94700)
displays nothing: ('[ZIPL]' > '94600' AND '[ZIPL]' < '94700')
displays nothing: ('[ZIPL]' > '94600') AND ('[ZIPL]' < '94700')
displays nothing: (('[ZIPL]' > '94600') AND ('[ZIPL]' < '94700'))

Please let me know if you've encountered same and found a way to eliminate those irksome errors; thanks.
