I have a table that contain a field names as mgrs, the value that stored in mgrs fields is like \'42SWC227821555\' may contain more charachters, and may contain lower case lette
Instead of BETWEEN clause use STRCMP(expr1, expr2) function for string comparison operations:
BETWEEN
WHERE STRCMP(mgrs, '42SWC227821555') >= 0 AND STRCMP(mgrs, '42SWC227821570') <= 0
