When I try to a call a Parameter within my SQL query, I’m getting this error “ORA-01036: illegal variable name/number”

This is my query -

“Select PON From (Select PON, order_number, order_version From CUPICSUP.ORDER_CONTENT_EXTRACT_MAIN Where ECCKT = ‘@IframeParameter’ Order By INSERTED_DATE DESC) Where ROWNUM = 1”

P:S - If I hard code the value in the place of Parameter. I’m able to get results

Someone please do help me with this issue. Your support is much appreciated.

Thanks in advance.

if this is a oracle SQL you are trying to fire then i have seen that instead of @ put :
Try with replacing the ECCKT = ‘@IframeParameter’ with ECCKT = :IframeParameter

I faced same issues replacing @ with : for parameter did not help. Instead I used assigned statement to build the string
