您可以将标量函数的输出与检查语句中的标量进行比较吗？ SQL
Can you compare the output of a scalar function with a scalar in a check statement? SQL
我想在创建 table 时将标量函数的输出与 CHECK 语句中的标量值进行比较，但它似乎无法进行正确的比较。如果标量函数 returns 1，我希望检查语句被“检查”。有什么办法可以做到这一点吗？ （该函数在最后一个检查语句中被调用）
语句 运行 成功，如果我 运行 函数退出 CHECK 函数它 return 是正确的值（0 或 1），但是当我插入函数returned值中满足1的数据，错误为returned。这是我的代码和我试过的代码，
CREATE TABLE COLONO (
numero INT,
nome NVARCHAR (150) NOT NULL,
dtnascimento DATE NOT NULL CHECK(DATEDIFF(year, dtnascimento, GETDATE()) BETWEEN 6 AND 17),
contacto NVARCHAR(50) CHECK(contacto LIKE '+351[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]'),
escolaridade INT NOT NULL CHECK(escolaridade BETWEEN 1 AND 12),
ccidadao VARCHAR(15),
cutente DECIMAL(10,0),
equipa INT NOT NULL FOREIGN KEY REFERENCES EQUIPA(numero),
PRIMARY KEY (numero),
UNIQUE (contacto),
UNIQUE (ccidadao),
UNIQUE (cutente),
CHECK(dbo.get_grupo6(equipa,DATEDIFF(year, dtnascimento, GETDATE())) = 1)
);
我的函数get_grupo6是
CREATE FUNCTION get_grupo6(@equipa INT,@idade INT)
RETURNS INT
AS
BEGIN
RETURN(
SELECT CASE WHEN @idade BETWEEN idademinima AND idademaxima THEN 1 ELSE 0 END
FROM grupo WHERE nome IN(SELECT grupo FROM equipa WHERE numero=@equipa)
)
END
创建grupo table如下
CREATE TABLE GRUPO (
nome NVARCHAR(25) CHECK(nome IN ('iniciados','júniores','séniores')),
idademinima INT NOT NULL CHECK(idademinima>5),
idademaxima INT NOT NULL CHECK(idademaxima<18),
PRIMARY KEY (nome),
CHECK(idademaxima>idademinima)
);
equipa table 的创建如下
CREATE TABLE EQUIPA (
numero INT,
grupo NVARCHAR(25) NOT NULL,
designacao NVARCHAR(150) NOT NULL,
PRIMARY KEY (numero),
FOREIGN KEY (grupo) REFERENCES GRUPO(nome),
);
当我插入数据时出现以下错误 return，即使该函数 return 将我期望的值 return （没有错误应该是 returned):
消息 547，级别 16，状态 0，第 219 行
INSERT 语句与 CHECK 约束“CK__COLONO__110145FE”冲突。冲突发生在数据库“master”，table“dbo.COLONO”。
该语句已终止。

马克思,
我发现您 table 中的 CHECK 语句没有错误。请参阅此处的 dbfiddle；它按预期工作，因为您尝试 INSERT 的值违反了 CHECK 语句并且将不起作用。
如果您单击 link 并向下滚动，您会看到根据您提供的数据，函数无法对其中的某些行 return 1。即，这是一个失败的例子：
INSERT INTO COLONO VALUES (368,'Matilde Borges','2013-03-20' /* dtnascimento */,
'+351922657141',6,'73250721',8286872705,35905,22 /* equipa */)
当我们逐步执行您的 dbo.grupo6 函数时，我们看到 equipa.numero = 22，它会显示 grupo = júniores，这需要年份在 11 和 14 之间。但是，从今天到提供的日期之间有 7 年，无法通过 CHECK。
在执行 INSERT 语句时没有办法真正捕获 this 的值（至少，在不使用 TRIGGERS 或 TRY-CATCH 尝试评估答案的情况下）。如果一个失败，所有的插入都将失败。如果数据模型是灵活的，您可以考虑使用位列来存储此结果，从而允许您在记录功能检查值的同时执行 INSERT。然后你可以查询在这个函数中有或没有 1 的那些，并进一步调查。
执行插入时，失败如下：
INSERT INTO COLONO (numero, nome, dtnascimento, escolaridade, eeducacao, equipa) values (2,'test', '2020-11-22', 1, 1, 1);
有错误：
The INSERT statement conflicted with the CHECK constraint "CK__COLONO__dtnascim__2E26C93A". The conflict occurred in database "TEST", table "dbo.COLONO", column 'dtnascimento'.
总能做到：
SELECT CHECK_CLAUSE
FROM INFORMATION_SCHEMA.CHECK_CONSTRAINTS
WHERE CONSTRAINT_NAME='CK__COLONO__dtnascim__2E26C93A';
给出输出：
CHECK_CLAUSE
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
(datediff(year,[dtnascimento],getdate())>=(6) AND datediff(year,[dtnascimento],getdate())<=(17))
(1 row affected)
这意味着 (datediff(year..... 语句是插入失败的原因。
我想在创建 table 时将标量函数的输出与 CHECK 语句中的标量值进行比较，但它似乎无法进行正确的比较。如果标量函数 returns 1，我希望检查语句被“检查”。有什么办法可以做到这一点吗？ （该函数在最后一个检查语句中被调用）
语句 运行 成功，如果我 运行 函数退出 CHECK 函数它 return 是正确的值（0 或 1），但是当我插入函数returned值中满足1的数据，错误为returned。这是我的代码和我试过的代码，
CREATE TABLE COLONO (
numero INT,
nome NVARCHAR (150) NOT NULL,
dtnascimento DATE NOT NULL CHECK(DATEDIFF(year, dtnascimento, GETDATE()) BETWEEN 6 AND 17),
contacto NVARCHAR(50) CHECK(contacto LIKE '+351[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]'),
escolaridade INT NOT NULL CHECK(escolaridade BETWEEN 1 AND 12),
ccidadao VARCHAR(15),
cutente DECIMAL(10,0),
equipa INT NOT NULL FOREIGN KEY REFERENCES EQUIPA(numero),
PRIMARY KEY (numero),
UNIQUE (contacto),
UNIQUE (ccidadao),
UNIQUE (cutente),
CHECK(dbo.get_grupo6(equipa,DATEDIFF(year, dtnascimento, GETDATE())) = 1)
);
我的函数get_grupo6是
CREATE FUNCTION get_grupo6(@equipa INT,@idade INT)
RETURNS INT
AS
BEGIN
RETURN(
SELECT CASE WHEN @idade BETWEEN idademinima AND idademaxima THEN 1 ELSE 0 END
FROM grupo WHERE nome IN(SELECT grupo FROM equipa WHERE numero=@equipa)
)
END
创建grupo table如下
CREATE TABLE GRUPO (
nome NVARCHAR(25) CHECK(nome IN ('iniciados','júniores','séniores')),
idademinima INT NOT NULL CHECK(idademinima>5),
idademaxima INT NOT NULL CHECK(idademaxima<18),
PRIMARY KEY (nome),
CHECK(idademaxima>idademinima)
);
equipa table 的创建如下
CREATE TABLE EQUIPA (
numero INT,
grupo NVARCHAR(25) NOT NULL,
designacao NVARCHAR(150) NOT NULL,
PRIMARY KEY (numero),
FOREIGN KEY (grupo) REFERENCES GRUPO(nome),
);
当我插入数据时出现以下错误 return，即使该函数 return 将我期望的值 return （没有错误应该是 returned):
消息 547，级别 16，状态 0，第 219 行 INSERT 语句与 CHECK 约束“CK__COLONO__110145FE”冲突。冲突发生在数据库“master”，table“dbo.COLONO”。 该语句已终止。 消息 547，级别 16，状态 0，第 220 行 INSERT 语句与 CHECK 约束“CK__COLONO__110145FE”冲突。冲突发生在数据库“master”，table“dbo.COLONO”。

马克思,
我发现您 table 中的 CHECK 语句没有错误。请参阅此处的 dbfiddle；它按预期工作，因为您尝试 INSERT 的值违反了 CHECK 语句并且将不起作用。
如果您单击 link 并向下滚动，您会看到根据您提供的数据，函数无法对其中的某些行 return 1。即，这是一个失败的例子：
INSERT INTO COLONO VALUES (368,'Matilde Borges','2013-03-20' /* dtnascimento */,
'+351922657141',6,'73250721',8286872705,35905,22 /* equipa */)
当我们逐步执行您的 dbo.grupo6 函数时，我们看到 equipa.numero = 22，它会显示 grupo = júniores，这需要年份在 11 和 14 之间。但是，从今天到提供的日期之间有 7 年，无法通过 CHECK。
在执行 INSERT 语句时没有办法真正捕获 this 的值（至少，在不使用 TRIGGERS 或 TRY-CATCH 尝试评估答案的情况下）。如果一个失败，所有的插入都将失败。如果数据模型是灵活的，您可以考虑使用位列来存储此结果，从而允许您在记录功能检查值的同时执行 INSERT。然后你可以查询在这个函数中有或没有 1 的那些，并进一步调查。
执行插入时，失败如下：
INSERT INTO COLONO (numero, nome, dtnascimento, escolaridade, eeducacao, equipa) values (2,'test', '2020-11-22', 1, 1, 1);
有错误：
The INSERT statement conflicted with the CHECK constraint "CK__COLONO__dtnascim__2E26C93A". The conflict occurred in database "TEST", table "dbo.COLONO", column 'dtnascimento'.
总能做到：
SELECT CHECK_CLAUSE
FROM INFORMATION_SCHEMA.CHECK_CONSTRAINTS
WHERE CONSTRAINT_NAME='CK__COLONO__dtnascim__2E26C93A';
给出输出：
CHECK_CLAUSE
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
(datediff(year,[dtnascimento],getdate())>=(6) AND datediff(year,[dtnascimento],getdate())<=(17))
(1 row affected)
这意味着 (datediff(year..... 语句是插入失败的原因。
