需要计算Mysql中字段的出现次数

Question

我有一个列中列出了一些值，我想计算组合字符串的出现次数

RowNo  DT1-Increased_CT_Reason_Start_to_Accept

1  ERIC_Drive Test Taking too Long;#ERIC_Lack Of GSC Resources/Queuing  DT  Drives;#ERIC_Cluster Having Too Many RF Issues Needing Tuning;#
2  ERIC_Drive Test Taking too Long;#ERIC_Lack Of GSC Resources/Queuing DT Drives;# 
3  ERIC_Drive Test Taking too Long;#
4  ERIC_Drive Test Taking too Long

我必须计算出现次数，我想要的输出是

DT1-Increased_CT_Reason_Start_to_Accept                   count  

ERIC_Drive Test Taking too Long                            4  
ERIC_Lack Of GSC Resources/Queuing  DT Drives              2
ERIC_Cluster Having Too Many RF Issues Needing Tuning      1
