Substance Abuse Addiction is a complicated disease that affects the behavior and functions of the brain. It occurs when a person becomes dependent on a drug or medication. This could include legal and illegal drugs, prescription drugs, and alcohol. Substance abuse not only affects individuals, it also affects their friends, family, and other people around them. In 2012, there was an estimated 23.1 million Americans aged 12 and older who needed treatment for substance abuse (SAMHSA, 2014). Educating ourselves and others on preventing and treating substance abuse disorders is important because it can affect a person’s physical and mental health. Substance abuse can affect anyone. Some people can be functioning addicts, meaning one would never knew they had a problem. Others have trouble keeping a job, forming romantic relationships, they become needy, and withdrawal from their family and friends. Physical dependence is when the body becomes adjusted to a substance, and needs that substance to function normally. Psychological dependence is when a person uses a substance to feel the effect it produces, but their body is not dependent on it. An individual may have biological and psychological characteristics that make them vulnerable to substance abuse. Biological characteristics include genes, gender, and ethnicity. Scientists estimate that genetic factors account for about 40-60 percent of a person’s vulnerability to drug addiction (NIH, 2014). Introducing drugs during adolescence also increases vulnerability due to the brain not being able to make wise decisions. Men are also more likely to become substance abusers. Psychological characteristics include personality disorders, such as anxiety, depression, or schizophrenia. When a person has a personality

Joins in Sql

SQL Join is used for combining column from two or more tables by using values common to both tables. JoinKeyword is used in SQL queries for joining two or more tables. Minimum required condition for joining table, is(n-1) where n, is number of tables. A table can also join to itself known as, Self Join. Types of Join The following are the types of JOIN that we can use in SQL. * Inner * Outer * Left * Right Cross JOIN or Cartesian Product This type of JOIN returns the cartesian product of rows from the tables in Join. It will return a table which consists of records which combines each row from the first table with each row of the second table. Cross JOIN Syntax is, SELECT column-name-list from table-name1 CROSS JOIN table-name2; Example of Cross JOIN The class table, ID | NAME | 1 | abhi | 2 | adam | 4 | alex | The class_info table, ID | Address | 1 | DELHI | 2 | MUMBAI | 3 | CHENNAI | Cross JOIN query will be, SELECT * from class, cross JOIN class_info; The result table will look like, ID | NAME | ID | Address | 1 | abhi | 1 | DELHI | 2 | adam | 1 | DELHI | 4 | alex | 1 | DELHI | 1 | abhi | 2 | MUMBAI | 2 | adam | 2 | MUMBAI | 4 | alex | 2 | MUMBAI | 1 | abhi | 3 | CHENNAI | ...

Outer Join and Scalar Queries

...and the number of sections that they have taught. Make sure to show the number of sections as 0 for instructors who have not taught any section. Your query should use an outer join, and should not use scalar subqueries. By using the university schema provided by db-book.com the following queries were done on the university database. The first query uses an outer join which works similar to the join operation but it keeps the rows that don’t match between the two tables that would be lost in a join operation. There are three forms of outer join: a) Left outer join displays the results from the left table even if the condition does not find any matching record in the right table. b) Right outer join will displays the results from the right table regardless if there is matching data in the left table. c) Full outer join will retain all rows from both tables, regardless if the data matches or not. The group by clause when used in a select statement collects data from multiple records and groups the results into one or more columns. The below is the query using left outer join operation: select ID, name, count(sec_id) as Number_of_sections from instructor natural left outer join teaches group by ID, name; The next query was written by using a scalar subquery without using an outer join operation. A scalar subquery is where the output of a subquery returns only one row which contains one single column/attribute. By using the select statement with count (*)...

Note

...In SQL, a join is used to compare and combine rows from two or more table. Inner Join: An inner join returns records only those records are common in both tables. Outer Join An outer join returns a set of records (or rows) that include what an inner join would return but also includes other rows for which no corresponding match is found in the other table. There are three types of outer joins: * Left Outer Join (or Left Join) * Right Outer Join (or Right Join) * Full Outer Join (or Full Join) Each of these outer joins refers to the part of the data that is being compared, combined, and returned. Sometimes nulls will be produced in this process as some data is shared while other data is not. Left Outer Join A left outer join will return all the data in Table 1 and all the shared data (so, the inner part of the Venn diagram example), but only corresponding data from Table 2, which is the right join. Right Outer Join A right outer join returns Table 2's data and all the shared data, but only corresponding data from Table 1, which is the left join. Full Outer Join A full outer join, or full join, which is not supported by the popular MySQL database management system, combines and returns all data from two or more tables, regardless of whether there is shared information. Think of a full join as simply duplicating all the specified information, but in one table, rather than multiple tables. Where matching data is missing, nulls will be produced. These...

Database Management

...Written Assignment 3 Explain the SQL commands Union, Intersect, and Minus with concepts like union-compatibility, and syntax alternatives such as IN/NOT IN and various JOIN options Database Management CIS-311 There are many different SQL commands. This assignment will focus on UNION, INTERSECT, and MINUS. UNION combines unique rows returned by two SELECT statements. UNION ALL functions in the same way as UNION except that it also returns duplicates. INTERSECT gives you rows that are found in both queries by eliminating rows that are only found in one or the other. An INTERSECT is simply an inner join where we compare the tuples of one table with those of the other, and select those that appear in both while weeding out duplicates. MINUS returns the rows that are in the first query but not the second by removing the rows that are only found in the second query. There are three primary SQL commands involved when implementing a Union, Intersection and difference relational operators. As you may know, SQL data manipulation commands are set-oriented which are involved in operating over entire sets of rows and columns in tables at once. The UNION, INTERSECT, and MINUS statements make sure these operations occur. Union, Intersect and Minus only work properly if relations are Union-Compatible, which is based on the names of the relation attributes that must be the same and their data types must be alike. Being compatible does not mean the data types have to be exactly the...

It was very interesting to see family from huge city such as New York living without car, subway,TV,taxi,refrigerator far from civilization. "No impact man" means no air conditioning, no newspapers, no shopping for new clothes, no disposable diapers,no coffee, no toilet paper because Colin was thinking what if he actually try not to impact environment.
