An administrator is writing into a database and received an error detailed in the exhibit. The two steps to be taken to resolve this are :
Move the Execute SQL statement to be between Connect and Disconnect. Move the Prompt Message to be before the Disconnect statements.
Explanation:
- Dynamic SQL refers to SQL statements that are generated at run-time.
- To disconnect from a database, in the Database Navigator or Projects view, click the connection and then click the Disconnect button in the toolbar or click Database -> Disconnect on the main menu
- You can also right-click the connection and click Disconnect on the context menu
- The PROMPT command may be used to display messages to the user, perhaps supplying a short summary of what your script is going to accomplish.
- The SQL EXECUTE command executes an SQL command and binds the result to 4D objects (arrays, variables or fields).
- A valid connection must be specified in the current process in order to execute this command. The sqlStatement parameter contains the SQL command to execute.
Answer:
ring network
Explanation:
In a ring network, the nodes are arranged in a circular pattern where each node is connected to two adjacent nodes. In this topology, any node can communicate with any other node via the intermediaries.
In comparison,
- in a star network every communication needs to pass through a central hub node
- in a bus, each node is connected to a shared linear communication bus.
- in a hierarchical network nodes are organized along a tree structure layout.
1)How many memory cards (how many can you computer hold)
2)Company (some companies run better than others)
3)Amount of memory (xGb)
Answer:
Explanation:
The following pseudocode for this method using operations of the ADT list would be the following
swap(aList, indexI, indexJ) {
initialize temp_variable = Retrieve(indexI, aList)
Insert(Retrieve(indexJ, aList), indexI, aList)
Insert(Retrieve(indexI, aList), temp_variable, aList)
}
This code basically saves the aList index of i , into a temporary Variable. Then it sets the aList index of i to the value of the element in index of j. Then it does the same for the index of j with the tem_variable. If we assume that the indexes of i and j exist, then it can crash our entire program if those indexes are missing from the list when we try to access them.
The difference is that system on a desk top preforms all the basic tasks like file management, memory management handling input and output and controlling peripheral devices such ad disk and printers where as some smart phone work on specific hardware
