See more:

Cscode:

string FIRST_NAME = txtFirstName.Text.Length == 0 ? null : txtFirstName.Text;

SP:

cmd.Parameters.AddWithValue("@FIRST_NAME", FIRST_NAME);

Error:

INSERT_NEW_STARTER_DETAILS' expects parameter '@FIRST_NAME', which was not supplied.

I am trying insert null value into database when the textbox is empty. but the SP insert the data when there is text in textbox and not inserting when it is empty (null).

Is there any other easy way to achieve it.

Thanks,
Sathish

Hello,

You can try this,
add null as default paramter value and don't pass any value if you want it to be null

example:

In your Sp

create procedure sp_PassNullValueInSp(@para1 varhcra(10), @para2 varchar(10)= null)

C# Code

cmd.Parameters.AddWithValue("@para1", "value1");
//No need to pass para2 if it is null
