A join is a characteristic of a relationship between two database objects. The join type determines which records appear when you run a query to show information from two tables. There are three types: Inner Join, Left Outer Join, and Right Outer Join. The default setting is Inner Join which draws only matching records in both tables.
A type of query which retrieves data from more than one object at a time. A join allows the user to select attributes from multiple objects, then returns the data as if were all stored together in one object.
A "join" is a concept within SQL queries. If you want to draw related data out of two (or more) different tables and you want to link them based on a common field, it is called a join. You can use "inner" or "outer"... read more ... Usefulness: N/A(0 ratings) by BuckyF () Rate It! this definition is ... useful somewhat useful incorrect spam / offensive
A SQL method of combining database tables in order to obtain the desired information. In a join, multiple tables are connected by specifying the relationship between a column in one table and a column in another table.
a mechanism for selecting which rows from two related tables are included in an SQL statement, based on equality (or some other relationship, such as inequality, greater than, and so on) between the contents of selected columns
A query that selects data from more than one table. The data selected from the different tables is determined by conditions specified within the FROM clause of the statement. These conditions are called join conditions.
A logical pairing of tables in a database, based on matching data in a specific column(s). Creating joins in Discoverer Administrator is critical for identifying the folders available to the user in Discoverer Plus. When the user selects an item or folder to create a worksheet, only those folders having joins with the selected folder are available. Thus, if a join does not exist between two folders, neither the unselected folder nor its items are available for the worksheet. Joins are derived from matching columns or primary or foreign keys in the database.
In a physical database, the act of retrieving information from two tables based on a matched value in their related same-domain attribute. Example: Join the Department table to the Employee table on the Dept# column.
To relate datasheets of information in a database. Two related tables will have a common column (field) that is the key to the relationship. Inner joins (aka equi-joins) bring together rows from two tables whose common field match. Outer joins also include unmatched rows. Left joins include all the rows from the first/left table. Right joins include all the rows from the second/right table. See also relationships.
A query that selects data from more than one table. A join is characterized by multiple tables in the FROM clause. Oracle pairs the rows from these tables using the condition specified in the WHERE clause and returns the resulting rows. This condition is called the join condition and usually compares columns of all the joined tables.
The operation that takes two relations (sets or tables) and produces one new relation (query result – set or view) by collecting the combined rows and matching the corresponding columns with a stated condition to test between the two.
An association between a field in one table or query and a field of the same data type in another table or query. Joins tell the program how data is related. Records that don't match may be included or excluded, depending on the type of join. walqaba View
An operation that combines data from two or more files using specified fields. In DB2 UDB for AS/400, a relational operation that allows the program to retrieve data from two or more tables based on matching column values. To become a new member of an entity such as a cluster.
Related Terms: relational database, table, SQL In traditional databases, a "join" is a SQL query that pulls records from multiple tables and connects the records via common fields. For example, a join between the employee table the department table could show the names of each department, and the names of each employee in that department. Full-text engines do not usually do "joins" at search time; if database data of that sort is to be searched then it would be joined at index time, not search time.
Combing two tabular data sets into a single one based on a common field. Two tables with a common domain combined into a single table. SQL query that retrieves data from two or more sources at once based on matching field values.
Unix-like operating systems that merges the lines of two sorted text files based on the presence of a common field. It is a sort of implementation of the join operator used in relational databases but operating on text files.
A join combines records from two or more tables in a relational database. In the Structured Query Language (SQL), there are three types of joins: inner, outer, and cross. Outer joins are subdivided further into left outer joins, right outer joins, and full outer joins.
In mathematics, a join on a set is defined either as unique suprema (least upper bounds) with respect to a partial order on the set, provided such suprema exist, or (abstractly) as a commutative and associative binary operation satisfying an idempotency law. In either case, the set together with the join is a join-semilattice. The two definitions yield equivalent results, except that in the partial order approach it may be possible directly to define joins of more general sets of elements.
To connect, usually permanently. Means of joining include the use of adhesives, nails, nuts and bolts, mortice and tenon, pegs, rivets, screws, solder, staples, stitches, tapes, velcro, weaving, welding, and wire.
Arguments based upon a common template can be merged through a join. The joint answer to each question, in the resulting argument, is based upon the independent answers, from the original arguments, captured as independent bodies of evidence in support of that question.
