我有两张桌子，一张是

peson contains(personid Identity, firstname,Lastname,PlaceOfBirth,Gender)

和另一个

Education contains (Eduid identity, egreename,boardUniver,yearOfPassing,obtainedMarks, personid)

现在我的问题是每个人都有超过 1 度，但有些人有 1 或 2 度，那么我该如何跳过插入查询？

第一个表

Create table person(personid int Identity(1,1) primary key, firstname nvarchar(40), Lastname nvarchar(40), PlaceOfBirth nvarchar(40), Gender nvarchar(10))

第二张表

create table Education(Eduid int identity(1,1) primary key, Degreename nvarchar(40), boardUniver nvarchar(40), yearOfPassing nvarchar(40), obtainedMarks numeric(10,2), personid int, 
constraint fk_eduPerson foreign key (personid) references person(personid))

存储信息的过程

Create procedure EmpDetails
(
    @Firstname nvarchar(40),  @Lastname nvarchar(40), @PlaceOfBirth nvarchar(40), @Gender nvarchar(8), 
    @Degreename0 int, @boardUniver0 nvarchar(40), @yearOfPassing0 nvarchar(20), @obtainedMarks0 int,
    @Degreename1 int, @boardUniver1 nvarchar(40), @yearOfPassing1 nvarchar(20), @obtainedMarks1 int,
    @Degreename2 int, @boardUniver2 nvarchar(40), @yearOfPassing2 nvarchar(20), @obtainedMarks2 int, 
)
AS BEGIN
declare @personid int
INSERT INTO person(firstname,Lastname,PlaceOfBirth,Gender) values(@firstname,@Lastname,@PlaceOfBirth,@Gender)
SELECT @personid=@@IDENTITY
if(@Degreename0 !=NULL)
    BEGIN
    INSERT INTO Education(Degreename,boardUniver,yearOfPassing,obtainedMarks, personid) values (@Degreename0,@boardUniver0,@yearOfPassing0,@obtainedMarks0, @personid)
    END
IF(@Degreename1 !=null)
  BEGIN
    INSERT INTO Education(Degreename,boardUniver,yearOfPassing,obtainedMarks, personid) values (@Degreename1,@boardUniver1,@yearOfPassing1,@obtainedMarks1, @personid)
  END
IF(@Degreename2!=null)
   BEGIN
    INSERT INTO Education(Degreename,boardUniver,yearOfPassing,obtainedMarks, personid) values (@Degreename2,@boardUniver2,@yearOfPassing2,@obtainedMarks2,@personid)
    END
END

这不起作用..这会将所有行插入空..还有其他解决方案吗？如果有其他建议请给我..谢谢

尝试IS NOT NULL代替!= NULL. 在大多数关系数据库中，如果任一输入为 ，则比较运算符将返回 false NULL，即使它们都是。这是一个演示该行为的 SQL Fiddle。

（对不起。那个 SQL Fiddle 真的很管用。）

诚然，这令人困惑，因为这一事实应该意味着您的所有INSERTs 都被跳过了。我在这里看不到任何会插入空行的东西。

试试这个——

Create procedure EmpDetails
(
    ...
)
AS BEGIN
    DECLARE @personid INT
    INSERT INTO Person (firstname, Lastname, PlaceOfBirth, Gender)
    SELECT @firstname, @Lastname, @PlaceOfBirth, @Gender

    SELECT @personid = SCOPE_IDENTITY()

    INSERT INTO Education (Degreename, boardUniver, yearOfPassing, obtainedMarks, PersonID)

    SELECT a = @Degreename0, b = @boardUniver0, c = @yearOfPassing0, d = @obtainedMarks0, e = @personid
    WHERE @Degreename0 IS NOT NULL

    UNION ALL

    SELECT @Degreename1, @boardUniver1, @yearOfPassing1, @obtainedMarks1, @personid
    WHERE @Degreename1 IS NOT NULL

    UNION ALL

    SELECT @Degreename2, @boardUniver2, @yearOfPassing2, @obtainedMarks2, @personid
    WHERE @Degreename2 IS NOT NULL

END
