Question

I’m trying to store a Int64 variable to data column with bigint data type. Following is my sql insert query and parameter declarations.

cmd.CommandText = "INSERT INTO tbl_subscribers VALUES ('@callerID2', '@timeStamp', '@unregisterDate ', '1')";

cmd.Parameters.Add("@callerID2", SqlDbType.BigInt);
        cmd.Parameters["@callerID2"].Value = SMSObject.callerID;
        cmd.Parameters.Add("@timeStamp", SqlDbType.DateTime);
        cmd.Parameters["@timeStamp"].Value = SMSObject.timeStamp.ToString("yyyy-MM-dd HH:mm:ss");
        cmd.Parameters.Add("@unregisterDate", DBNull.Value);
        cmd.Parameters["@unregisterDate"].Value = DBNull.Value;

When it try to store the data, I get

Error converting data type varchar to bigint.

Any advices?
