CREATE TABLE t1(a char(10)); INSERT INTO t1 VALUES('0123456789'); SELECT CASE WHEN REGEXP_LIKE(a,CHR(0)) THEN 1 ELSE 0 END col, DUMP(a) FROM t1; The output I am getting like this - col dump(a) ----------- ----------------------------------- 1 Typ=96 Len=10: 48,49,50,51,52,53,54,55,56,57 I am totally confused, if there is no chr(0) as shown by the dump(a), how regexp_like is finding the chr(0) in the column and returning 1? Shouldn't it return 0 here? CHR(0) is the character used to terminate a string in the C programming
