按顺序插入SQL

我有一个SQL表，其中有一列名为

信用卡代码

数据例

CCARD-000093
CCARD-000094
CCARD-000095
CCARD-000096
CCARD-000097
CCARD-000098
CCARD-000099
CCARD-000100
CCARD-000101

将数据插入此表时，如何获取序列中的下一个值

这就是我目前所拥有的

SELECT 'CCARD-' + 
(SELECT CAST(MAX(CAST(SUBSTRING(ccc.CreditCardCode,7, 6) as INT)) AS 
NVARCHAR(MAX)) FROM CustomerCreditCard ccc)

这就产生了CCARD-101

如何使其返回

CCARD-000101

？

如果要在插入记录时增加表，可以使用Identity和Presisted概念自动增加

IF OBJECT_ID('TestTables', 'U') IS NOT NULL 
BEGIN
    DROP TABLE TestTables 
END

从要开始的位置重置标识

DBCC checkident ('TestTables', reseed, 93)

CREATE TABLE TestTables
(
    CreditCard AS ('CCARD-0000' + CAST(AutoIncId as varchar)) PERSISTED NOT NULL PRIMARY KEY,    
    [AutoIncId] INT IDENTITY NOT NULL,
    [Bank] VARCHAR(10)
);


INSERT INTO TestTables ([Bank]) VALUES ('Indus')
INSERT INTO TestTables ([Bank]) VALUES ('ICICI')
INSERT INTO TestTables ([Bank]) VALUES ('HDFC')
INSERT INTO TestTables ([Bank]) VALUES ('DBS')

SELECT * FROM TestTables

下一个值，固定长度，前导为“0”：

SELECT 'CCARD-' + RIGHT(REPLICATE('0',6)+CAST(1+MAX(CAST(SUBSTRING(ccc.CreditCardCode,7, 6) as INT)) AS NVARCHAR(6)),6) 
FROM CustomerCreditCard ccc

SELECT 'CCARD-' + RIGHT(REPLICATE('0',6)+CAST(1+MAX(CAST(SUBSTRING(ccc.CreditCardCode,7, 6) as INT)) AS NVARCHAR(6)),6) 
FROM CustomerCreditCard ccc

这似乎奏效了

INSERT INTO CustomerCreditCard (CustomerCode, CreditCardCode, CreditCardDescription, NameOnCard, Address, City, State, PostalCode, Country, ExpMonth, ExpYear, Telephone, Email, IsActive,  ResidenceType, UserCreated, DateCreated, UserModified, DateModified, County, StartMonth, StartYear)
  SELECT c.CustomerCode, 
    (SELECT 'CCARD-' + REPLICATE('0', 6 - LEN((SELECT CAST(MAX(CAST(SUBSTRING(ccc.CreditCardCode,7, 6) as INT)) + 1 AS NVARCHAR(MAX)) FROM CustomerCreditCard ccc))) +
(SELECT CAST(MAX(CAST(SUBSTRING(ccc.CreditCardCode,7, 6) as INT)) + 1 AS NVARCHAR(MAX)) FROM CustomerCreditCard ccc)), 
    'Web Credit Card',
    c.CustomerName, 
    c.Address, 
    c.City, 
    c.State, 
    c.PostalCode, 
    c.Country, 
    'Jan', 
    2025, 
    c.Telephone, 
    c.Email, 
    1, 
    c.ResidenceType, 
    'webadmin', 
    GETDATE(), 
    'webadmin', 
    GETDATE(), 
    c.County, 
    'Jan',
    2010
    FROM Customer c
  WHERE c.CustomerCode = 'CUST-015056'

请共享序列代码和

next value for

返回的内容。我无法正确获取

next value for

的语法，因此无法使其返回值。您最好对此数据使用计算列，只需使用常规int标识即可。这样，您就不必担心下一个值的计算。请共享序列代码和
