问题一:这标红色的符号 取掉
一直没有见过标红色的符号,尝试把这些符号粘贴出来到 notepad 发现它是乱码,尝试将它粘贴到sql查询分析器里,发现它显示空白。对于这样的数据,一直想着找到这个acsi码,然后问题就迎刃而解了。 结果找了一大堆的相关资料,都没有类似的问题。最后,采用直线式思维,直接索性就把那个字符粘到Sql查询分析器的窗口里,解决方案如下:
SELECT
[F0L_MID],
ltrim(rtrim(REPLACE([F0L_MID],'',' ')))
FROM [pfvaults].[dbo].[OMEGAFld]
问题以然解决,哪位高手要是遇见 标红的 字符,还请一块出来分享,看那个到底是什么东东
筛选出FOL_MID字符串除过 前后标红的特殊字符,以空格开始或者以空格结尾的 结果集(注意where后的条件)
SELECT
[F0L_MID]
FROM [pfvaults].[dbo].[OMEGAFld]
where
[F0L_MID] like ' %' or
[F0L_MID] like '% '
