出现的ssrs数据集中没有字段-动态SQL

Question

我正在尝试使用数据库名称作为@CATALOG参数通过SSRS运行此操作，但不会填充字段列表。 任何建议将不胜感激。

DECLARE @SQLScript AS NVARCHAR(4000)

SET @SQLScript = 
'USE ' +@CATALOG + CHAR(13) +
'SELECT
    LD.ProvSpecMon_A AS Dept,
    LD.ProvSpecMon_C AS SubjArea,
    LD.ProvSpecMon_B AS CourseCode,
    L.LearnRefNumber AS PersonCode,
    CASE 
        WHEN L.PlanEEPHours + L.PlanLearnHours >= 540 THEN 'FT' 
        ELSE 'PT'
    END AS LearnerType,
    LD.AimType,
    LD.LearnAimRef AS LearningAim,
    AIM.LearnAimRefTitle AS LearningAimTitle,
    EFA.OnProgPayment,
    EFA.StartFund
FROM Valid.Learner L
INNER JOIN Valid.LearningDelivery LD
    ON LD.LearnRefNumber = L.LearnRefNumber
LEFT JOIN Rulebase. DV_Learner AGE
    ON AGE.LearnRefNumber = L.LearnRefNumber
LEFT JOIN Rulebase.EFA_LEARNER EFA
    ON EFA.LearnRefNumber = L.LearnRefNumber
LEFT JOIN Rulebase.EFALearningDeliveryLARSInput AIM
    ON AIM.AimSeqNumber = LD.AimSeqNumber
    AND AIM.LearnRefNumber = LD.LearnRefNumber
WHERE
    EFA.StartFund = 1
    AND LD.AimType = 5
ORDER BY
    L.LearnRefNumber'

EXECUTE sp_executesql @SQLScript

如果要参数化目录，则必须参数化连接字符串。

在数据源属性中，选择“ Embedded connection ，然后在连接字符串表达式中添加参数。

您可以在连接字符串中使用参数：

="Data Source=" & Parameters!ServerName.Value & ";Initial Catalog=" & Parameters!Catalog.Value
