For SQL Management studio I used a variation of BWS  answer  This gets the data to the right of      or NULL if the symbol doesn t exist      CASE WHEN  RIGHT supplier reference  CASE WHEN  CHARINDEX     supplier reference 0     0 THEN     0 ELSE CHARINDEX      supplier reference  -1 END    lt  gt     THEN  RIGHT supplier reference  CASE WHEN  CHARINDEX     supplier reference 0     0 THEN     0 ELSE CHARINDEX      supplier reference  -1 END   ELSE NULL END

In MySQL  this works if there are multiple     characters in the string  SUBSTRING supplier reference FROM  LOCATE     supplier reference  1     It returns the substring after  1  having found the the first

I ve been working on something similar and after a few tries and fails came up with this   Example  STRING-TO-TEST-ON    ab cd ef gh   I wanted to extract everything after the last occurrence of      comma  from the string    resulting in  gh    My query is   SELECT SUBSTR  ab cd ef gh  FROM  LENGTH  ab cd ef gh   -  LOCATE     REVERSE  ab cd ef gh   -1  1   AS  wantedString    Now let me try and explain what I did       I had to find the position of the last     from the string and to calculate the wantedString length  using LOCATE     REVERSE  ab cd ef gh   -1 by reversing the initial string I actually had to find the first occurrence of the     in the string     which wasn t hard to do     and then -1 to actually find the string length without the      calculate the position of my wantedString by subtracting the string length I ve calculated at 1st step from the initial string length    LENGTH  ab cd ef gh   -  LOCATE     REVERSE  ab cd ef gh   -1  1   I have   1  because I actually need the string position after the last        and not containing the      Hope it makes sense    all it remain to do is running a SUBSTR on my initial string FROM the calculated position    I haven t tested the query on large strings so I do not know how slow it is  So if someone actually tests it on a large string I would very happy to know the results
