Sql 发生连接时将字符串转换为uniqueidentifier

我想创建一个存储过程，但我得到了一个错误，在一段时间后，我发现“ret_payrollcalculationInfo”包含xml列，并将BankGuid和BankBranchGuid存储为字符串，而不是uniqueidentifier，并且无法连接到它们的表

<BankGuid>92434DE6-3D3C-43F1-A89E-869AE5456B07</BankGuid>
<BankBranchGuid>00000000-0000-0000-0000-000000000000</BankBranchGuid>
<PayrollItemGuid>482C44DD-ECFB-4B79-9118-86B681CC51C9</PayrollItemGuid>
<SalariedType>1</SalariedType>

92434DE6-3D3C-43F1-A89E-869AE5456B07
00000000-0000-0000-0000-000000000000
482C44DD-ECFB-4B79-9118-86B681CC51C9

我想知道在发生内部连接时是否有方法强制转换uniqeidentifier。这里有一些代码

CREATE PROCEDURE [dbo].[ret_PayrollCalculations_GetCalculationSummaries]
(
    @CalculationCommandGuid uniqueidentifier,
    @OperationalUnitIDs varchar(512)
)
AS
DECLARE @UnitIds TABLE([ID] INT primary key)
IF ISNULL(@OperationalUnitIDs, '') <> ''
    INSERT INTO @UnitIds SELECT Distinct [Column] FROM com_udfSplit(@OperationalUnitIDs, ',')

SELECT DISTINCT
    calculaion.[PersonnelNo],
    calculaion.[FullName],
    calculaion.[Amount],
    calcInfo.[AccountNo],
    calcInfo.[SalariedType],
    bank.[Title],
    branch.[Title]
FROM
    ret_PayrollCalculationCommands command INNER JOIN
    ret_vwPayrollCalculations calculaion ON command.[Guid] = calculaion.[CalculationCommandGuid] INNER JOIN
    ret_PayrollCalculationInfo calcInfo ON calculaion.[Guid] = calcInfo.[PayrollCalculationGuid] INNER JOIN
    gen_Banks bank ON calcInfo.[BankGuid]   = bank.[Guid] INNER JOIN
    gen_Branches branch ON calcInfo.[BankBranchGuid] = branch.[Title]
WHERE
command.[Guid] = @CalculationCommandGuid

创建过程[dbo]。[ret\u PayrollCalculations\u GetCalculationSummaries]
(
@CalculationCommandGuid唯一标识符，
@操作单元ID varchar（512）
)
作为
声明@UnitID表（[ID]INT主键）
如果为空（@operationalUnitId，“”）
插入到@UnitIds中，从com_udfSplit（@OperationalUnitIDs，，）中选择不同的[Column]
选择不同的
计算，
计算。[全名]，
计算[金额]，
[AccountNo]，
calcInfo。[受薪类型]，
银行[名称]，
分支机构[名称]
从…起
ret_PayrollCalculationCommands命令内部联接
ret_vwPayrollCalculations Calculation ON命令。[Guid]=Calculation。[CalculationCommandGuid]内部联接
ret_PayrollCalculationInfo Calculation ON Calculation。[Guid]=Calculation。[PayrollCalculationGuid]内部联接
CANCINFO上的gen_bank银行。[BankGuid]=银行。[Guid]内部联接
gen_在calcInfo上分支分支机构。[BankBranchGuid]=分支机构。[标题]
哪里
命令。[Guid]=@CalculationCommandGuid

您只需将

VARCHAR

值强制转换为

唯一标识符

，例如：

CAST('482C44DD-ECFB-4B79-9118-86B681CC51C9' AS UNIQUEIDENTIFIER)

因此，您的

JOIN

子句变成这样：

ON command.[Guid] = CAST(calculaion.[CalculationCommandGuid] AS UNIQUEIDENTIFIER)
