Question

美好的一天，

我想选择一个平均字段

的表格

SELECT 
    CAST(SurveyDept AS NVARCHAR(100)) as Dept_name,
    CAST(SurveySubDept AS NVARCHAR(100)) as Subdept_name
    AVG(SurveyReachability) as total_R,
    AVG(SurveyProfessionalism) as total_P,
    AVG(SurveyProactiveness) as total_Pr,
    AVG(SurveyCompetence) as total_C,
    AVG(SurveyResponse) as total_Re
FROM 
    dbo.tb_SurveyDeptInfo 
GROUP BY 
    CAST(SurveyDept AS NVARCHAR(100)), 
    CAST(SurveySubDept AS NVARCHAR(100))
ORDER BY 
    CAST(SurveyDept AS NVARCHAR(100)),
    CAST(SurveySubDept AS NVARCHAR(100))

结果如下：

我想要做的是将“子部门名称”排除在值（转移）和价值（检查和公用事业服务付款）（如果存在）

所以我在（order by）之后添加了以下内容：

WHERE Subdept_name NOT IN (SELECT *
                           FROM dbo.tb_SurveyDeptInfo
                           WHERE CAST(SurveySubDept AS NVARCHAR(100)) = 'Transfers'
                              OR CAST(SurveySubDept AS NVARCHAR(100)) = 'Check & Utility Service Payments')

你能告诉问题在哪里，它没有返回任何记录

Answer 1

只需将beforeToHtml子句添加到整个查询中：

public function beforeToHtml(\Magento\Catalog\Block\Product\View\Description $originalBlock)
{
    $originalBlock->setTemplate('Vendorname_Modulename::description.phtml');
}

您的查询无效，因为您有WHERE。子查询返回多个列，因此会出错。

我不明白你为什么要向SELECT CAST(SurveyDept AS NVARCHAR(100)) as Dept_name, CAST(SurveySubDept AS NVARCHAR(100)) as Subdept_name AVG( SurveyReachability ) as total_R, AVG( SurveyProfessionalism ) as total_P, AVG( SurveyProactiveness ) as total_Pr, AVG( SurveyCompetence ) as total_C, AVG( SurveyResponse ) as total_Re FROM dbo.tb_SurveyDeptInfo WHERE CAST(SurveySubDept AS NVARCHAR(100)) NOT IN ('Transfers', 'Check & Utility Service Payments') GROUP BY CAST(SurveyDept AS NVARCHAR(100)), CAST(SurveySubDept AS NVARCHAR(100)) ORDER BY CAST(SurveyDept AS NVARCHAR(100)),CAST( SurveySubDept AS NVARCHAR(100));做明确的案件。这些似乎只是混乱了查询。我会尝试：

IN (SELECT * . . )

试试这个

[DisplayName("JSON Extraction Rule")]
[Description("Extracts the specified JSON value from an object.")]
public class JsonExtractionRule : ExtractionRule
{
    [DisplayName("Name/path of attribute")]
    [Description("String to fetch the attribute from the Json Object.")]
    public string Name { get; set; }

    [DisplayName("Fetch 4 first characters only")]
    [Description("Set to true if only the first 4 characters of the attribute should be fetched.")]
    public Boolean fourFirstCharacters { get; set; }

    public override void Extract(object sender, ExtractionEventArgs e)
    {
        if (e.Response.BodyString != null)
        {
            var json = e.Response.BodyString;

            if (json.StartsWith("["))
            {
                json = "{\"array\":" + json + "}";
            }

            var data = JObject.Parse(json);

            if (data != null)
            {
                var attribute = data.SelectToken(Name).ToString();
                if (fourFirstCharacters)
                {
                    e.WebTest.Context.Add(this.ContextParameterName, attribute.Substring(0, 4));
                } else
                {
                    e.WebTest.Context.Add(this.ContextParameterName, attribute);
                }                   
                e.Success = true;
                return;
            }
        }

        e.Success = false;
        e.Message = String.Format(CultureInfo.CurrentCulture, "Not Found: {0}", Name);
    }
}

SQL select查询排除值
