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:
2^32 times as many values can be represented
Explanation:
32-bit. This means that the number is represented by 32 separate one’s and zero’s. 32 bits of 2 possible states = 2^32=4,294,967,296 possible values.
Integer meaning that only whole multiples of one are accepted.
Signed meaning that negative values are accepted. This halves the number of possible positive values (roughly), so the largest number you can represent is 2^31–1=2,147,483,647, but instead of 0, the smallest number you can represent is -2,147,483,648. An unsigned 32-bit integer, by contrast, can represent anything from 0 to 4,294,967,295.
Answer: Discretionary access control (DAC)
Explanation: Discretionary access control is the control system that is imposed over the information system. The information systems contains different objects and subjects that gets the permission to do the operations.
The operation which the components can do are sharing the data to other object or subjects, privilege providence, change in the rules for the access, security entities getting changed etc.
Here is a somewhat cryptic solution that works:
#include <algorithm>
#include <cstdlib>
using namespace std;
void q(char c, int count)
{
for (int i = 0; i < count; i++) {
putchar(c);
}
}
void p(int b1, int plusses)
{
q(' ', b1);
q('+', plusses);
}
int main()
{
for (int i = -3; i <= 3; i++)
{
int pl = min(6, (3 - abs(i)) * 2 + 1);
p(6-pl, pl);
i == 0 ? p(0, 6) : p(6, 0);
p(0, pl);
putchar('\n');
}
getchar();
}
