Calendar in my country is solar calendar. since Microsoft SQL not support from solar Calendar engineers for make database for date field use string data type instead date. and now i have a challenge with string date fields. i want now, how can change my date field to date without conversion to Georgian calendar?
I don't understand the request very well.
But because luna calendar date is completely different from normal calendar dates,
you only can show luna dates as "integer" other than string.
In that sense simply " int([luna day]) " is the only way to show luna day.
This shows from 1~29 or 30 as integer.
As you know, you can not use any "date" function on this field.
