result of select query for date field - JS date object?

Posted by gwf on 02-May-2016 12:22

As part of a series of select queries I want to be able to test whether a field is a date. This server-side code returns false:

function main () {
  var isthisadate = rbv_api.selectQuery('SELECT field1#value FROM object1', 1);
  return isthisadate[0][0] instanceof Date;
}

main();

And this code returns [object JavaObject]:

function main () {
  var isthisadate = rbv_api.selectQuery('SELECT field1#value FROM object1', 1);
  var toString = Object.prototype.toString;
  return toString.call(isthisadate[0][0]);
}

main();

So is the result of the select query not a JS date object? How do I test whether the data type of the field is a date?

Thank you,

Greg

Hi Greg,

The return type of select query will be array of strings irrespective of the data type being used in object column.

Please use rbv_api.formatDate(arg1, pattern) function which will format the date according the format specified in the parameter. It will return a valid date , if arg1 is a valid date otherwise it will return null.

Example:

var date=rbv_api.selectQuery("SELECT dateField FROM SampleObject",1);
var formatDate=rbv_api.formatDate(date[0][0], "yyyy-MM-dd HH:mm:ss");
if(formatDate){
rbv_api.println("valid date");
}else
{
rbv_api.println("invalid date");
}

Shiva
