It is very important to remember that whenever we want to join the tables it is mandatory that there should be at least one common field between them. Without a common field between the tables we can not join the tables.

All rights reserved. Quick Reference. Joins the columns of two or more data sources in a results set in a join expression. The following applies to entries specified on the left side and on the right side:. The priority in which nested join expressions are evaluated is specified by the position of the ON conditions. Join expressions of this type can be enclosed in parentheses,. This is optional. Explicitly specified parentheses must match the parentheses specified implicitly by the ON conditions. See Multiple Joins. In a single results set, an inner join joins the columns of the rows in the results set of the left side with the columns of the rows in the results set of the right side. See Inner and Outer Joins. The outer join creates the same results set as the inner join.

See Multiple Joins. Pooled and cluster tables cannot be joined using join expressions.

Sometimes it is necessary to combine two SQL data sources into one result set, consisting of columns of both data sources. This is called a join. As an example, when reading flight connections, it can be necessary to read details on the flight carrier, too, for example, the name of the carrier. The rows of the result set are determined by the join type and by join conditions between columns of the data sources. The join conditions start with keyword ON and define relations between columns of the data sources.

Notes Explicit parentheses can be used in nested join expressions to stress the parentheses specified by the ON conditions and are recommended for readability. Unknown 25 March at Also this inner join will fetch the data from the tables if the record is available in all the tables that you are joining. The syntax check is performed in strict mode for SP05 in the following cases: Not all comparisons of an ON condition contain a column from a data source specified on the right side as an operand. Join expressions of this type can be enclosed in parentheses,. Explicitly specified parentheses must match the parentheses specified implicitly by the ON conditions. This is because the join condition is evaluated fully in the database and no ABAP type conversion takes place beforehand. Path expressions cannot be used. An inner join or a cross join between two individual data sources is commutative. Join expressions bypass SAP buffering.

In the case of multiple consecutive joins, a join expression and not a database source is on the right side of a join expression. A join expression can therefore be nested recursively. Example Join the columns carrid , carrname , and connid of the database tables scarr and spfli using a left outer join. However, databases generally offer fewer conversion options than ABAP. Join the columns carrid , carrname , and connid of the database tables scarr and spfli using a left outer join. So if it is not available in one of the tables, the data will not be fetched. Subqueries cannot be used. A join expression can be specified for join on both sides. Read more. The function coalesce can be used to replace zero values created due to an external join with other values or the result of expressions. Path expressions cannot be used. Inner join.
