Question

我有一个列，让我们说Col_A的值为The subscriber already handles the [Price plan][%]. The subscriber cannot handle it again.注意通配符%。现在，我传入以下输入参数：The subscriber already handles the [Price plan][MyProduct]. The subscriber cannot handle it again.

我需要执行一个LIKE语句，该语句将返回相同的行，与我将指定的[Price plan][******]无关。

我尝试过以下操作，但未找到任何行：

select * from LD_DATA
  where UPPER(Col_A) LIKE UPPER('The subscriber already handles the [Price plan][test]. The subscriber cannot handle it again.');

请注意'The subscriber already handles the [Price plan][test]. The subscriber cannot handle it again.'是我的输入参数变量。

请帮忙吗？

Answer 1

如果我清楚地理解你的问题

 select * from LD_DATA
      where UPPER(Col_A) LIKE UPPER('The subscriber already handles the %. The subscriber cannot handle it again.');

Answer 2

必须切换WHERE条件才能使输入参数与列值匹配，反之亦然。

所以，而不是where UPPER(Col_A) LIKE UPPER('The subscriber already handles *)它应该是where UPPER('The subscriber already handles *') LIKE UPPER(Col_A)

Answer 3

您必须使用[]包围特殊字符（或范围）。你不需要逃离结束括号。 select * from LD_DATA where Col_A LIKE 'the subscriber already handles the [[]Price plan][[]%]. the subscriber cannot handle it again.';

SQL LIKE语句匹配内部值
