Masked SQL Query
is there a function of some kind that can search by masked param? example: pass a 5 char value XDWTR and return all rows that match any char. combinations from another table that has the masked values: AW_, _CH, _DW, _DW,____R. my masked values are always 5 char. this search would return 2 matches the _DW___ because the second and third DW match the second and third value of XDWTR. the other ___DW_ starts in the 3rd pos. so it's not a match. the ____R is a match because it's the last pos. that matches the R in XDWTR.
any helpful example would be great.

I think you want:
where masked_param like concat('%', masked_value, '%')
If the masked values are really five characters, then the concat() is not necessary:
where masked_param like masked_value
This is using the fact that _ is the escape character in like for any single character.
