我有一个包含两列的数据库,一个日期,然后是一个句子的列。示例:" 2016-12-5" "我今天去了商场"。如何将这些句子列分成每行一个单词,同时仍将它们连接到正确的日期?

使用split
功能:
CREATE FUNCTION [dbo].[Split]
(@String VARCHAR (max), @Delimiter CHAR (1))
RETURNS
@temptable TABLE (
[items] VARCHAR (max) COLLATE SQL_Latin1_General_CP1_CI_AS NULL)
AS
begin
declare @idx int
declare @slice varchar(max)
select @idx = 1
if len(@String)<1 or @String is null return
while @idx!= 0
begin
set @idx = charindex(@Delimiter,@String)
if @idx!=0
set @slice = left(@String,@idx - 1)
else
set @slice = @String
if(len(@slice)>0)
insert into @temptable(Items) values(@slice)
set @String = right(@String,len(@String) - @idx)
if len(@String) = 0 break
end
return
end
创建函数后,试试这个:
SELECT '2016-12-5' AS [Date],items Value FROM dbo.Split('I went out to the mall today',' ')
