Question

以下查询从现有数据库中提取特定数据：

SELECT (
   SELECT AttributeData FROM SQLTable1 WHERE AttributeName = 'File Name') AS File_Name,
  (SELECT AttributeData FROM SQLTable WHERE AttributeName = 'Version Number') AS Version,
  (SELECT 'Category Name') AS Category,
   CAST(LEFT((SELECT AttributeData FROM SQLTable1 WHERE AttributeName = 'Duration 1'), 
   CHARINDEX('m', (SELECT AttributeData FROM SQLTable1 WHERE AttributeName = 'Duration 1'),1 )-2) AS float) AS Value,
   GETDATE() AS Date
FROM SQLTable2
GROUP BY FinalDisposition

UNION

SELECT (
   SELECT AttributeData FROM SQLTable1 WHERE AttributeName = 'File Name') AS File_Name,
  (SELECT AttributeData FROM SQLTable WHERE AttributeName = 'Version Number') AS Version,
  (SELECT 'Category Name') AS Category,
   CAST(LEFT((SELECT AttributeData FROM SQLTable1 WHERE AttributeName = 'Duration 1'), 
   CHARINDEX('m', (SELECT AttributeData FROM SQLTable1 WHERE AttributeName = 'Duration 1'),1 )-2) AS float) AS Value,
   GETDATE() AS Date
FROM SQLTable2
GROUP BY FinalDisposition

UNION

SELECT (
   SELECT AttributeData FROM SQLTable1 WHERE AttributeName = 'File Name') AS File_Name,
  (SELECT AttributeData FROM SQLTable WHERE AttributeName = 'Version Number') AS Version,
  (SELECT 'Category Name') AS Category,
   CAST(LEFT((SELECT AttributeData FROM SQLTable1 WHERE AttributeName = 'Duration 1'), 
   CHARINDEX('m', (SELECT AttributeData FROM SQLTable1 WHERE AttributeName = 'Duration 1'),1 )-2) AS float) AS Value,
   GETDATE() AS Date
FROM SQLTable2
GROUP BY FinalDisposition

这会创建一个如下所示的表：

| File_Name | Version |  Category  | Value |           Date          |
|:---------:|:-------:|:----------:|:-----:|:-----------------------:|
| File1     | 1.0.1   | Duration 1 |  0.04 | 2017-04-17 12:00:00.000 |
| File2     | 1.0.1   | Duration 2 | 0.008 | 2017-04-17 12:00:00.000 |
| File3     | 1.0.1   | Duration 3 | 0.066 | 2017-04-17 12:00:00.000 |

作为旁注，价值具有＆＃34;额外＆＃34; bits是因为原始数据的格式如下所示：0.04 minutes，0.008 minutes和0.066 minutes。我想摆脱这些分钟并投下一个漂浮物。

如何将该数据插入到另一个表中（我已将此表格与我要插入的表格的列格式相同）。

或者换句话说，如何将该信息移动到这样的插入语句中：

INSERT INTO [Database].dbo.SQLTable3(File_Name,Version,Category,Value,Date)

Answer 1

    INSERT INTO SQLTable3
    SELECT *
    FROM(   

            SELECT (
               SELECT AttributeData FROM SQLTable1 WHERE AttributeName = 'File Name') AS File_Name,
              (SELECT AttributeData FROM SQLTable WHERE AttributeName = 'Version Number') AS Version,
              (SELECT 'Category Name') AS Category,
               CAST(LEFT((SELECT AttributeData FROM SQLTable1 WHERE AttributeName = 'Duration 1'), 
               CHARINDEX('m', (SELECT AttributeData FROM SQLTable1 WHERE AttributeName = 'Duration 1'),1 )-2) AS float) AS Value,
               GETDATE() AS Date
            FROM SQLTable2
            GROUP BY FinalDisposition

            UNION

            SELECT (
               SELECT AttributeData FROM SQLTable1 WHERE AttributeName = 'File Name') AS File_Name,
              (SELECT AttributeData FROM SQLTable WHERE AttributeName = 'Version Number') AS Version,
              (SELECT 'Category Name') AS Category,
               CAST(LEFT((SELECT AttributeData FROM SQLTable1 WHERE AttributeName = 'Duration 1'), 
               CHARINDEX('m', (SELECT AttributeData FROM SQLTable1 WHERE AttributeName = 'Duration 1'),1 )-2) AS float) AS Value,
               GETDATE() AS Date
            FROM SQLTable2
            GROUP BY FinalDisposition

            UNION

            SELECT (
               SELECT AttributeData FROM SQLTable1 WHERE AttributeName = 'File Name') AS File_Name,
              (SELECT AttributeData FROM SQLTable WHERE AttributeName = 'Version Number') AS Version,
              (SELECT 'Category Name') AS Category,
               CAST(LEFT((SELECT AttributeData FROM SQLTable1 WHERE AttributeName = 'Duration 1'), 
               CHARINDEX('m', (SELECT AttributeData FROM SQLTable1 WHERE AttributeName = 'Duration 1'),1 )-2) AS float) AS Value,
               GETDATE() AS Date
            FROM SQLTable2
            GROUP BY FinalDisposition)X

将解析后的数据从一个数据库插入另一个数据库
