For each item below, specify whether the statement is true (T) or false (F). It is possible for the system to generate attribute values automatically in order for users not to have to specify the value of an attribute in the INSERT INTO statement. For an attribute declared in this fashion, we can still specify values in the INSERT INTO statement. When you create a Foreign Key Constraint in SQL Server, the system automatically creates an index on the referencing attributes. While creating a CHECK constraint, if there are tuples violating the condition we specify as part of the CHECK constraint, "cascading" specification eliminates these inconsistencies. "cascading" specification causes all "violating tuples" to be deleted. The wildcard character *', means 0 or 1 character. In other words, it matches zero or one character. We can not specify group conditions if we do not group the tuples. Therefore, In a SELECT statement HAVING clause can not be specified without a GROUP BY clause. | CROSS JOIN = INNER JOIN WHERE is always TRUE. The ´character used in an SQL SELECT statement means "all the tuples". JOIN combines two relations. It takes the second relation, and appends it to the end of the first relation. OUTER JOIN types return only nonmatching tuples.
