为什么此查询不适用于数字1？

时间：2011-09-21 14:09:35

标签： sql sql-server

此查询按预期返回5个结果

select * from [SalesLogix].[sysdba].[LEAD] where USERFIELD1 like '0'

但此查询不返回任何内容

select * from [SalesLogix].[sysdba].[LEAD] where USERFIELD1 like '1'

USERFIELD1是varchar 80字段

以下是数据库中的所有数据，你可以看到有两条记录，其中USERFIELD1 ='1'但它们之后似乎有一个换行符...可能是导致问题...无论如何都要抓住那两个记录

4 个答案:

答案 0 :(得分：4)

如果userField1中的1之后有字符，请尝试使用通配符，如下所示。

select * from [SalesLogix].[sysdba].[LEAD] where USERFIELD1 like '1%'

你写的声明

select * from [SalesLogix].[sysdba].[LEAD] where USERFIELD1 like '1'

基本上等同于

select * from [SalesLogix].[sysdba].[LEAD] where USERFIELD1 = '1'

您可能想要阅读LIKE clause

http://msdn.microsoft.com/en-us/library/ms179859.aspx

答案 1 :(得分：1)

使用

 where USERFIELD1 = '1
 '

您不需要LIKE，因为您没有使用任何外卡。

答案 2 :(得分：1)

  • 您使用LIKE错误。在其中放置通配符或模式，或使用=运算符。
  • 您的数据似乎格式不正确。

答案 3 :(得分：1)

尝试使用通配符

包围的值

即USERFIELD1 like '1%'

如果与换行符相关的话，应该排除你遇到的任何问题
