Hi rajendren,

select a~num

a~bgcnam

b~qnum

INTO TABLE itab

from AQGDBBG as a

join AQLQCAT as b

on b_{num eq a}num

[Former Member]

select a_{num a}bgcnam b~qnum into table itab

from aqgdbbg as a inner join aqlacat as b

on a_{num = b}num.

Joined tables are used in a select statement to combine data from two or more tables that share one or more columns. With Open SQL you can use inner join and left outer join.

Syntax

')'.

If the join is a left outer join the following additional restrictions apply to the search condition:

· The search condition must contain comparison predicates only

· Comparison predicates can only be combined by use of AND

· Each comparison predicate can compare two columns, where the two columns must be from the respective tables that are to be joined. If the left hand side of the join is itself a join, the column reference must not be from a outer table (where outer table is the right table of a left outer join). The comparison predicate can also compare one column reference from a table on the right-hand side of the join with a constant value.

Examples

SELECT employee_name, manager_name

FROM employees AS e JOIN managers AS m

ON e.manager_id = m.manager_id

The INNER JOIN. This query produces a list of all employees that have a manager along with their respective managers. Here, the FROM clause contains an inner join of two tables.

SELECT employee_name, manager_name

FROM employees AS e LEFT OUTER JOIN managers AS m

ON e.manager_id = m.manager_id

The LEFT OUTER JOIN. This query produces a list of all employees along with their respective managers. If an employee does not have a manager, the manager’s name is NULL. Here, the FROM clause contains an left outer join of two tables.

Hope this clarified your doubt.
