How to INSERT an array of values in SQL Server 2005?

Question

如何编写SQL代码来INSERT（或UPDATE）一个值数组（可能是一个伴随的字段名数组，或者带有两者的矩阵），而不需要简单的迭代？

Answer 1

I construct the list as an xml string and pass it to the stored procs. In SQL 2005, it has enhanced xml functionalities to parse the xml and do a bulk insert.

Answer 2

Simple way to concatenate the values into a list and pass it to the sp.

In the sp use dbo.Split udf to convert back to resultset (table).

Create this function:

CREATE FUNCTION dbo.Split(@String nvarchar(4000), @Delimiter char(1))
returns @Results TABLE (Items nvarchar(4000))
as
begin
declare @index int
declare @slice nvarchar(4000)

select @index = 1
if @String is null return

while @index != 0

begin
select @index = charindex(@Delimiter,@String)
if @index !=0
select @slice = left(@String,@index - 1)
else
select @slice = @String

insert into @Results(Items) values(@slice)
select @String = right(@String,len(@String) - @index)
if len(@String) = 0 break
end return
end

and then try:

select * from dbo.split('a,b,c,d,e,f,g,h,i,j,k,l', ',')

I understand that you are talking about writing stored procedure to accept array of values

With SQL Server 2005 you would need to use XML variable

SQL 2008 adds support to table variable as parameters

Here you can find good examples of passing a table to a stored procedure as XML and as table variable (SQL Server 2008)

If your data is already in the database you could use INSERT SELECT syntax. It's slightly different from INSERT VALUES one...

INSERT recipient_table (field1, field2)
SELECT field1_from, field2_from
FROM donor_table
WHERE field1_from = 'condition'
