For example, if a hash aggregate operator is used in the first step of a query plan, full data of downstream operators is required to create a hash table for an aggregate operation. For common queries with filter conditions, data is calculated and returned in real time. In this scenario, ...
wild, if given, is a pattern string. It can contain the SQL % and _ wildcard characters. In this case, the statement displays output only for the columns with names matching the string. There is no need to enclose the string within quotation marks unless it contains spaces or other ...

2) Explain why functions with an array parameter are usually complemented with an additional integer parameter (reference specifics in this workshop to explain your answer). Explain what does the following function do: void foo(Queue *q, Stack *s) { while (!q->isEmpty() { s->push(q->...
Type casting isa method used to change the variables/ values declared in a certain data type into a different data type to match the operation required to be performed by the code snippet. In python, this feature can be accomplished by using constructor functions like int(), string(), float...
PLAN_TABLE cannot be joined with GDS foreign tables. For a query that cannot be pushed down, only such information as REMOTE_QUERY and CTE can be collected from PLAN_TABLE after EXPLAIN PLAN is executed. For details, see Example 2. PLAN: saves plan information into PLAN_TABLE. If informati...

A string, for example, is a data type that is used to classify text and an integer is a data type used to classify whole numbers. The data type defines which operations can safely be performed to create, transform and use the variable in another computation. There are two types of data...
