如何在Sql server 2008R2中搜索日期时间(How to Search datetime in Sql server 2008R2)

我有一个SQL搜索的问题。 我想在datetime的帮助下搜索,因为在我的项目中,时间非常重要。 当我使用这样的查询

where registration_date = '2014-06-19 00:12:08.940' 

它确实有效,但一旦我尝试搜索使用

where registration_date like '2014-06-19%' 

我没有结果。 因为我想搜索在特定日期(包括时间)发生的所有注册,我假设我不知道具体时间...


i am having problem with a sql search . i am trying to search with the help of datetime because in my project time is very important. when i use query like this

where registration_date = '2014-06-19 00:12:08.940' 

it does works but as soon as i try to search using

where registration_date like '2014-06-19%' 

i get no results. because i want to search for all the registration taken place on a specific date including time, i am assuming that i dont know the specific time...

最满意答案

我使用for循环尝试了这一点。 检查这个简单的例子是否适合你。 接受了这篇文章的命令。

RM = rm -f
FLAGS =  -Cr -O1 -gv -gw -g -vw
builddir = ./build/
TD = ./tasks/
SHELL := /bin/bash

targets=$(shell for file in `find . -name '*.pas' -type f -printf "%f\n" | sed 's/\..*/\.out/'`; do echo "$$file "; done;)

all: $(targets)

%.out:%.pas
  fpc $< $(FLAGS) -o (builddir)$@

clean:
    $(RM) $(builddir)*

I tried this out using a for loop. Check if this simple example works for you. Took the command from this post.

RM = rm -f
FLAGS =  -Cr -O1 -gv -gw -g -vw
builddir = ./build/
TD = ./tasks/
SHELL := /bin/bash

targets=$(shell for file in `find . -name '*.pas' -type f -printf "%f\n" | sed 's/\..*/\.out/'`; do echo "$$file "; done;)

all: $(targets)

%.out:%.pas
  fpc $< $(FLAGS) -o (builddir)$@

clean:
    $(RM) $(builddir)*
