我想根据姓名、企业名称、大学名称、技能名称搜索表格。
假设我将按名称搜索一次，按企业名称搜索，再次按大学名称搜索，但是当我输入名称时，我单击搜索按钮我会显示正确。但是，当我输入企业名称或大学名称时，我无法正确输入企业名称列，就像 null 一样。
我写了一个这样的存储过程：
ALTER PROCEDURE [dbo].[SearchPeople_test]
(
@FirstName nvarchar(255),
@Location nvarchar(100),
@MembershipUserID uniqueidentifier,
@UniversityName nvarchar(255),
@Postcode nvarchar(20),
@BusinessName nvarchar(255),
@AssociateMemberID uniqueidentifier,
@SkillName nvarchar(255),
@Debits int,
@Gender int
)
AS
BEGIN
SET @SkillName = [dbo].[fnGetMemberskills](@AssociateMemberID)
SET @Debits = [dbo].[fnGetMembersSpentCredits](@AssociateMemberID)
SET NOCOUNT ON;
SELECT DISTINCT AssociateMember.ID AS ID
,AssociateMember.Firstname AS FirstName
,AssociateMember.Lastname AS LastName
