All three join operations work in a similar manner, with the difference being the rows that are returned. A left join and right join are also commonly called "semi-joins." Both operate in the same manner, with the difference being which table is the primary table. In a left join, all rows on the left-hand table that meet the criteria are returned, even if there is no matching right-hand table data for that row. A right join is the complementary version of a left join; all rows on the right-hand table are returned, even if there is no left-hand table data. A full join returns all matching rows, even if there is no data on either the left-hand table or the right-hand table.

No. Being able to join the military is not considered a human right, and governments have full reign to impose restrictions on who may or may not join their armed forces.
"Joint" typically refers to connecting or combining two things together, such as joints in the body or a joint effort. "Join" refers to the act of coming together or connecting with others to form a group or alliance.

In right-to-work states, workers are not required to join a union or pay union dues as a condition of employment. This can lead to lower union membership rates and potentially weaker unions. In non right-to-work states, workers can be required to join a union or pay union dues, which can result in higher union membership rates and stronger unions.
Full outer join will fetch at maximum 'addition of 2 tables' Ex: Table A - 2 rows; Table B - 3 rows. Full outer join will fetch in 2+3 = 5 rows. Where as in Cartesian product will fetch in 'product of 2 tables'. Ex: Table A - 2 rows; Table B - 3 rows. Full outer join will fetch in 2x3 = 6 rows
Join is used to combine related tuples from two relations . Full outer join cover all possible combinations of common tuples.
The difference between a full penetration weld and a deep penetration weld is the depth at which the metals being joined are actually joined. A full penetration weld is a slight puncture only to heat the two metals and join them. A deep penetration weld is a deeper hole puncture that is held and a metal wire is melted to join the metals.
In order to join to tables you must use enable the Join Properties dialog box. To make this box appear, right click the relationship line between both tables.

An INNER JOIN between two tables means that the joining values have to be present in both tables, while an FULL JOIN means that the values can be in either of the two tables. This is also know as a FULL OUTER JOIN.As an example, imagine a customer table with a code,name and type and an auxiliary table with a type id and type description;select * from Customer1 Record One 0012 Number 2 0013 The third 002Select * from CustomerType001 Type_one003 Another One(you'll notice that the type code '002' is missing).select Customer.Name, Customer.TypeCode, TypeCode.Description from Customer INNER JOIN CustomerType on (CustomerType.Code = Customer.TypeCode)Record One 001Number 2 001(The third record is missing because there wasn't a corresponding value in the CustomerType table for the inner join)select Customer.Name, Customer.TypeCode, TypeCode.Description from Customer FULL JOIN CustomerType on (CustomerType.Code = Customer.TypeCode)Record One 001Number 2 001The third 002(Which works because of the FULL - aka OUTER - JOIN)
