sqlxml

问题 I have XML data that is used to store quiz results. I need to convert this into two tables, one containing the questions, and the other containing the answers, but crucially, have a relation between them. Currently this relation only exists in the XML structure (there are no ID values, etc.). After a day of research and testing out different approaches, I've got as far as extracting the two parts, but cannot figure out how to create the hierarchy: declare @xml xml = N'<quizresult> <question>

问题 I've tried using "FOR XML PATH", "FOR XML EXPLICIT" and "FOR XML AUTO" but the data is never structured with the correct heirarchy. Basically, I have one parent table (Customers) and 3 child tables. Each table has a customerid column. There is a one-to-many relationship from the Customers table to each of the 3 child tables. As a mock example, I have a parent "Customers" table, and I have 3 other tables - Products, Hobbies and Vehicles - all related to the Customers table by a customerid.

问题 I am generating a XML file from a SQL Server query. I have some problem about sorting elements issues. For example, there is simple code as below. <test> <tree abc="123"/> <tree abc="789"/> <tree-order abc="456"/> </test> As you can see tree and tree-order are different elements and I want to sort by attributes as <test> <tree abc="123"/> <tree-order abc="456"/> <tree abc="789"/> </test> like this. Anyone has good idea to solve this problem? Thank you. Sorry I have detail question as below AS

问题 I'm trying to generate an XML output from SQL and need to use a UNION statement and also name the output column. I had this working before when I didn't need to use a UNION statement using: select( SELECT [CompanyName], [Address1], [Address2], [Address3], [Town], [County], [Postcode], [Tel], [Fax], [Email], [LocMap] FROM [UserAccs] FOR XML PATH ('AccountDetails'), root ('Root') ) as XmlOutput Which named the output XML column as XmlOutput I am now trying: select( SELECT [CompanyName],

问题 is there any chance of getting the output from a MySQL query directly to XML? Im referring to something like MSSQL has with SQL-XML plugin, for example: SELECT * FROM table WHERE 1 FOR XML AUTO returns text (or xml data type in MSSQL to be precise) which contains an XML markup structure generated according to the columns in the table. With SQL-XML there is also an option of explicitly defining the output XML structure like this: SELECT 1 AS tag, NULL AS parent, emp_id AS [employee!1!emp_id],

问题 I have a large XML file that I need to import and parse into tabular structure ("flatten") in SQL Server. By "large" I mean a file that is around 450 MB, contains up to 6-7 nested levels and lots of elements, ~300. I tried parsing the file both with OPENXML and Xml.Nodes . Both of the methods are slow. A partial query which reads a parent element and it's nested grandchildren takes several minutes if not dozens to run. I tried using the SQLXML Bulk Load method. Unfortunately I couldn't -

问题 I have XML stored in my table. This table has columns id type int, and value type XML. I'm using SQL Server 2012. XML looks like this: <?xml version="1.0" encoding="utf-16"?> <Weather> <Forecast> <Description>sky is clear</Description> <Date>6.9.2013 23:50:36</Date> <MinTemp>13</MinTemp> <MaxTemp>13</MaxTemp> <Pressure>995</Pressure> <Humidity>68</Humidity> </Forecast> </Weather> This XML can have up to then Forecast parts. How can I with simple SELECT statement get for instance Humidity
