Solution 1

RuleId column requires a value. Here you are not passing it into the stored procedure.
The direction is an OUPUT parameter.

SqlParameter p3 = cmd.Parameters.Add("@RuleID", SqlDbType.Int);
p3.Direction = ParameterDirection.Output;

ALTER procedure [dbo].[uspInsertRuleset] @RuleSetID int out
,@RuleTypeID int out,
@RuleID int out,
@minRange nvarchar(20),
@maxRange nvarchar(20),
@invalidChars nvarchar(50),
@isMandatory bit,
@allowZeroAsValue bit,
@RuleSetName nvarchar(20),
@UserID int,
@RuleTypeName nvarchar(20),
@RuleName nvarchar(50)
as
begin

select @RuleTypeID=rtRuleTypeID from dbo.pltblRuleTypes where rtRuleTypeName=@RuleTypeName;

select @RuleID=rulesRuleID from dbo.tblRules where ruleAttribute=@RuleName and rulesRuleTypeID=@RuleTypeID;

select @RuleSetID=Max(rsetRuleSetID)+1 from dbo.tblUserRuleSet

IF @RuleSetID is null
set @RuleSetID=1;
ELSE
select @RuleSetID=Max(rsetRuleSetID)+1 from dbo.tblUserRuleSet

alter table [dbo].[linkRulesRuleSets] nocheck constraint all

INSERT INTO [dbo].[linkRulesRuleSets]
([RuleSetID]
,[RuleTypeID]
,[RuleID]
,[minRange]
,[maxRange]
,[invalidChars])
VALUES
(@RuleSetID,
@RuleTypeID,
@RuleID,
@minRange,
@maxRange,
@invalidChars)

alter table [dbo].[linkRulesRuleSets] check constraint all

end
this is my stored procedure and rule id is not null
