All of them return boolean TRUE, FALSE, or NULL depending upon the boolean values of the operands.

hive.evaluation is set to true (which is the default) a UDF can give incorrect results if it is nested in another UDF or a Hive function.

This bug affects releases 0.12.0, 0.13.0, and 0.13.1. NULL if A or B is NULL, TRUE if string A matches the SQL simple regular expression B, otherwise FALSE. The _ character in B matches any character in A (similar to .

in posix regular expressions) while the % character in B matches an arbitrary number of characters in A (similar to .* in posix regular expressions).

For example, 'foobar' like 'foo' evaluates to FALSE whereas 'foobar' like 'foo_ _ _' evaluates to TRUE and so does 'foobar' like 'foo%'.

NULL if A or B is NULL, TRUE if any (possibly empty) substring of A matches the Java regular expression B, otherwise FALSE.

For example, 'foobar' RLIKE 'foo' evaluates to TRUE and so does 'foobar' RLIKE '^f.*r$'. The type of the result is the same as the common parent(in the type hierarchy) of the types of the operands.For example since every integer is a float, therefore float is a containing type of integer so the + operator on a float and an int will result in a float. The type of the result is the same as the common parent(in the type hierarchy) of the types of the operands. When A and B are both integers, the result is a double type except when the hive.compat configuration parameter is set to "0.13" or "latest" in which case the result is a decimal type.Note that if the multiplication causing overflow, you will have to cast one of the operators to a type higher in the type hierarchy. The following operators provide support for creating logical expressions.The following built-in collection functions are supported in Hive:.For example, cast('1' as BIGINT) will convert the string '1' to its integral representation.A null is returned if the conversion does not succeed.
