I have list of thigs to be checked like A,B,C is present in col2 at some rows number of tabl3…
So do i have some function which gives like true or false…or anything like that

Answer 1

You can test if one string exits within a string (e.g. a column in your table) with the INSTR function, or with the LIKE operator:

SELECT * FROM mytable WHERE INSTR(col2, 'A') > 0

SELECT * FROM mytable WHERE col2 LIKE '%A%'

You can then add additional predicates by using the OR operator.
