Hello Everyone

i am working on some portlet issue, where the background query for this portlet is having the code like this SELECT trunc(NVL(:param_startdate, sysdate), 'DY') + 1 cur_monday FROM dual.

:param_startdate is not taking any values given in the format like this: 02062017, 06022017, 06-FEB-2017, 020617, 060217and 06-FEB-17. this giving me an error.

ORA-01722: invalid number
01722. 00000 -  "invalid number"
*Cause:    The specified number was invalid.
*Action:   Specify a valid number.


checked this ora-01722 in google, its saying :The attempted conversion of a character string to a number failed because the character string was not a valid numeric literal. Only numeric fields or character fields containing numeric data may be used in arithmetic functions or expressions. Only numeric fields may be added to or subtracted from dates.

not sure where i am missing any value/type/format.

waiting for your wonderful solutions:)
