sql server duplicate values ​​are counted after

The existing name is converted to Pinyin, a0101 is the name, and a0103 is the pinyin generated by executing the stored procedure

The requirement is that if a0103 is repeated, add '1' after the second data
Add '2' to the third data

Example:
Insert name Liu Min to generate liumin
Insert Liu Min to generate liumin1
Insert Liu Min to generate liumin2

Thanks
