附加信息

Duplicate of NIM042471. At 10.0 REST API supports input in JSON representation for defintion query which should be used for this case.

解决办法

1) add a new field (in the database) to store a numeric date representation (float, e.g.).2) convert values in the date field to the new numeric field.3) alter javascript code according to the following example to apply the definition based on the numeric field values (without any conversion of dates whatsoever):layerDefs[0] = "DateFloat < 20071231235900"; //value is: YYYYMMDDhhmmssYou could also store datetime values in a float field in the same format used by the JavaScript getTime() function (milliseconds since midnight of 1/1/1970). Use getTime() in the application to convert the desired datetime for the layer definition. Something like:d = new Date();d.setMonth(12);d.setDate(31);d.setYear(2007);d.setHours(23);d.setMinutes(59);d.setSeconds(0);time = d.getTime();layerDefs[0] = "DateMS > " + time;
