1.xml.exist Enter an XQuery expression that returns either 0,1 or null. 0 means not present, 1 indicates existence, NULL indicates NULL input 2.xml.value Enter an XQuery expression that returns a SQL Server scalar value 3.xml.query Enter an XQuery expression that returns a SQL Server XML type stream 4.xml.nodes Enter an XQuery expression that returns a set of row

First, Introduction One of the major changes in Microsoft SQL Server 2005 is the inclusion of XML data types. This data type is the first class type, just like INT or VARCHAR, and SQL Server 2005 allows you to query and process this data type in-place using a series of XML-s

SQL for xml query sample, xmlsample Sample 1: declare @x xml select @x=' select @x.query('/ArrayOfScheduledTime/ScheduledTime/RecurrenceType')/* Select o. value ('recurrencetype [1] ', 'varchar (20)') 'recurrencetype 'from (select @ x 'X') t cross apply x. nodes ('/ArrayOfScheduledTime/ScheduledTime') x (o)/* Rec

I often want to use data set parameters for processing stored procedures, but SQL server does not provide such services. Oracle seems to have, and this is the gap ~~~ There is no way for SQL Server to be used in this way. Although SQL server does not explicitly provide a data set parameter, we can use some of its functions to implement it.

follows:SELECT Hobbyid as ' MyCode ', hname as ' MyName ' from @hobby for XML PATH (' Myhobby ')So at this point the node name of our column will also be programmed with our custom name Oh! Now that we can customize the nodes and columns of the row, can we build the output that we like? Or look at the code:SELECT ' [' +hname+ '] ' from @hobby for XML PATH (')Yes, we can also define the output format of a S

Sometimes it may be useful to associate or analyze data from SQL Server to other departments at once, a requirement that is certainly simple for SSIS, but a lot of times it makes a fuss to create a SSIS package just by exporting the data one at a time, while the SQL The Import Export tool for the server there are a lot of bugs, the easiest way is to bcp. Data exported to

Data exported to XML After SQL Server 2005, a FOR XML clause is provided to natively support XML in a relational database. This command enables you to convert a two-dimensional relational result set to XML, which can be saved as

ObjectiveIn SQL Server sometimes we need to descendant a table in the past, then we can batch update in the stored procedure, get the corresponding data in batches.But the parameters of the stored procedure are fixed, so here we can work around the parameters of the XML type, and then convert it directly into the table we need in the stored procedure.Specific imp

the code:SELECT '[ '+hname+' ]' from @hobby for XML PATH (") Yes, we can also define the output format of a String type field by using the symbol + number. The results are as follows:[climbing] [swimming] [food]So how do other types of columns customize? That's OK, let's convert them to string type! For example:SELECT‘{‘+str (Hobbyid) + ' } ",[ ' +hname+" ] "from @hobby forxml path ( ")
