1.7. LTRIM函数、RTRIM(函数和TRIM函数——删除指定字符串 LTRIM(s1,s2)函数用来删除字符串s1左边的字符串s2 RTRIM(s1,s2)函数用来删除字符串s1右边的字符串s2 TRIM(s2 FROM s1)函数用来删除字符串s1左右两端的字符串s2 如果在这3个函数中不指定字符串s2,则表示去除相应方位的空格。 select LTRIM('***hello**...
Rtrim(string)返回不带后导空格的字符串副本,即除去字符串后面的空格; Trim(string)返回不带前导空格与后导空格的字符串副本,即除去前面与后面的空格; string是参数任何有效的字符串表达式,如果string中包含NULL,则返回NULL。 二. Len函数,返回字符串内字符的数目或者是储存一变量所需的字节数 Len(string|varname...
