To generate a data point in this table, we start from a possible password P0, compute its fingerprint, h(P0) and then compute a new possible password R(h(P0)), which becomes P1. Next, we continue this process from P1. Without storing anything other than P0, we compute the sequence P1, P2,... until the fingerprint starts with 20 zeros; that fingerprint is designated h(Pn). Such a fingerprint occurs only once in about 1,000,000 fingerprints because the result of a hash function is similar to result of a uniform random draw, and 220 is roughly equal to 1,000,000. The password/fingerprint pair [P0, h(Pn)], containing the fingerprint that starts with 20 zeros is then stored in the table.

For a good database with almost no gaps, the memory needed to store the calculated pairs is a million times smaller than that needed for method 2, as described earlier. That is less than four one-terabyte hard disks. Easy. Also, as will be seen, using the table to derive passwords from stolen fingerprints is quite doable.

Many computations must be done to establish the first and last column of the rainbow table. By storing only the data in these two columns and by recomputing the chain, hackers can identify any password from its fingerprint.

We will start off by giving the keywords ALTER TABLE, then we will follow it up by giving the original name of the table, after that, we will give in the keywords RENAME TO and finally, we will give the new table name.

We will start off by giving the keywords DELETE FROM, then we will give the name of the table, and after that we will give the WHERE clause and give the condition on the basis of which we would want to delete a row.

Generally, in a table, we will have a lot of redundant information which is not required, so it is better to divide this complex table into multiple smaller tables which contain only unique information.

The INNER JOIN creates a new result table by combining column values of two tables (table1 and table2) based upon the join-predicate. The query compares each row of table1 with each row of table2 to find all pairs of rows which satisfy the join-predicate.

There are so many times where user needs to find out the specific constraint information of the table. The following queries are useful, SELECT * From User_Constraints; SELECT * FROM User_Cons_Columns;

The output of Cross Join is called a Cartesian product. It returns rows combining each row from the first table with each row of the second table. For Example, if we join two tables having 15 and 20 columns the Cartesian product of two tables will be 1520=300 rows.

Our database comprises of a lot of different entities such as tables, stored procedures, functions, database owners and so on. To make sense of how all these different entities interact, we would need the help of schema. So, you can consider schema to be the logical relationship between all the different entities which are present in the database.

We will start off by giving the keywords ALTER TABLE, then we will give the name of the table, following which we will give the keywords DROP COLUMN and finally give the name of the column which we would want to remove.

A trigger is a stored program in a database which automatically gives responses to an event of DML operations done by inserting, update, or delete. In other words, is nothing but an auditor of events happening across all database tables.

We start off by giving the keywords INSERT INTO then we give the name of the table into which we would want to insert the values. We will follow it up with the list of the columns, for which we would have to add the values. Then we will give in the VALUES keyword and finally, we will give the list of values.

Yes, SQL server drops all related objects, which exists inside a table like constraints, indexex, columns, defaults etc. But dropping a table will not drop views and sorted procedures as they exist outside the table.

A live lock is one where a request for an exclusive lock is repeatedly denied because a series of overlapping shared locks keep interferring. A live lock also occurs when read transactions create a table or page.

When two or more tables have been joined using equal to operator then this category is called an equi join. Just we need to concentrate on the condition is equal to (=) between the columns in the table.

We start off with the keywords CREATE UNIQUE INDEX, then give in the name of the index, after that, we will give the ON keyword and follow it up with the name of the table. Finally, in parenthesis, we will give the list of the columns which on which we would want this unique index.

We start off by giving the keywords ALTER TABLE, then we will give in the name of the table. After that, we will give in the keywords MODIFY COLUMN. Going ahead, we will give in the name of the column for which we would want to change the datatype and finally we will give in the data type to which we would want to change.

IN MYSQL, we will start off by using the ALTER TABLE keywords, then we will give in the name of the table. After that, we will use the CHANGE keyword and give in the original name of the column, following which we will give the name to which we would want to rename our column.

In ORACLE, we will start off by using the ALTER TABLE keywords, then we will give in the name of the table. After that, we will use the RENAME COLUMN keywords and give in the original name of the column, following which we will give the TO keyword and finally give the name to which we would like to rename our column.

A view is a database object that is created using a Select Query with complex logic, so views are said to be a logical representation of the physical data, i.e Views behave like a physical table and users can use them as database objects in any part of SQL queries.

A trigger allows you to execute a batch of SQL code when an insert,update or delete command is run against a specific table as Trigger is said to be the set of actions that are performed whenever commands like insert, update or delete are given.

Aggregate functions are used to evaluate mathematical calculations and return single values. This can be calculated from the columns in a table. Scalar functions return a single value based on input value.

SQL Constraints are used to specify the rules of data type in a table. They can be specified while creating and altering the table. The following are the constraints in SQL: NOT NULL CHECK DEFAULT UNIQUE PRIMARY KEY FOREIGN KEY

In SQL cross join, a combination of every row from the two tables is included in the result set. This is also called cross product set. For example, if table A has ten rows and table B has 20 rows, the result set will have 10 * 20 = 200 rows provided there is a NOWHERE clause in the SQL statement.

A query first takes the lowest level lock possible with the smallest row level. When too many rows are locked, the lock is escalated to a range or page lock. If too many pages are locked, it may escalate to a table lock.

From the Object Explorer window pane, go to the table where the column is present and choose Design. Under the Column Name, select the name you want to rename and enter the new name. Go to the File menu and click Save.

Indexes are database objects which help in retrieving records quickly and more efficiently. Column indexes can be created on both Tables and Views. By declaring a Column as an index within a table/ view, the user can access those records quickly by executing the index. Indexes with more than one column are called Clustered indexes.

In such cases, if the saft has been maintained, a quick pump-out and immediate lowering of the water table can be done if needed, in order to avoid flooding of the basement and the probable ruin of any valuable items located there.

The saft should extend above the basement floor until the highest observed level of the water table plus a safety margin of at least 50 cm, because according to the principle of communicating vessels, after the pumping-out stops, the water level inside the saft will rise to the same height as the water level around the basement. 041b061a72
