Question

您好我正在尝试在sql server中运行以下存储过程，并给出以下错误

在预期条件的上下文中指定的非布尔类型的表达式，接近＆＃39; LeadStatus＆＃39;。

存储过程只是更新字段＆＃39; RecQuality＆＃39;基于LeadStatus＆＃39;的价值column..RecQuality是一个整数字段。找到下面的存储过程

   Create Procedure [dbo].[ETL_SetRecordWeightsForLeadStatus]
    @TableName as varchar(50) ,
    @FieldName as varchar(50) 

As
Begin


    Declare @Sql nvarchar(500);



        SET @Sql = 'Update [dbo].[' + @TableName + '] 
                    Set RecQuality = Case When [' + @FieldName + '] = ''Tier-1'' Then  RecQuality +100
                                          When [' + @FieldName + '] = ''Tier-2'' Then  RecQuality +90
                                          When [' + @FieldName + '] = ''Tier-3'' Then  RecQuality +80
                                          When [' + @FieldName + '] = ''Tier-4'' Then  RecQuality +70
                                          When [' + @FieldName + '] = ''Tier-5'' Then  RecQuality +60
                                          When [' + @FieldName + '] = ''Tier-6'' Then  RecQuality +50
                                          When [' + @FieldName + '] = ''Tier-0'' Then  RecQuality +40
                                          Else  RecQuality +0 End 
                     Where LEN([' + @FieldName + ']) > 0 ';





    Execute sp_executesql @Sql;

End

当我运行下面的Sql时，单独用值运行正常的参数替换参数。

Update [dbo].[CannonListTest_WithStatus_deduped1] 
                Set RecQuality = Case When LeadStatus = 'Tier-1' Then  RecQuality +100
                                      When LeadStatus= 'Tier-2' Then  RecQuality +90
                                      When LeadStatus = 'Tier-3' Then  RecQuality +80
                                      When LeadStatus = 'Tier-4' Then  RecQuality +70
                                      When LeadStatus = 'Tier-5' Then  RecQuality +60
                                      When LeadStatus = 'Tier-6' Then  RecQuality +50
                                      When LeadStatus = 'Tier-0' Then  RecQuality +40
                                      Else  RecQuality +0 End 
                 Where LEN(LeadStatus) > 0

我无法准确找到问题所在。可以帮助我解决错误吗？

Answer 1

用于存储查询的nvarchar变量（@Sql）对于您使用的查询来说不够大。所以改变

Declare @Sql nvarchar(500);

到

Declare @Sql nvarchar(max);

在预期条件的上下文中指定的非布尔类型的表达式，接近＆＃39; LeadStatus＆＃39;
