Next, LOOP AT GROUP BY can be used for grouping and determine the number of lines per group.ĭATA itab TYPE TABLE OF i WITH NON-UNIQUE KEY table_line.įINAL(rnd) = cl_abap_random_int=>create( seed = + sy-uzeit The internal table itab is sorted by its primary key in descending order, This sort direction can be overwritten after the addition BY for components listed individually here. Specified, the table is sorted in ascending order. To specify the sort direction explicitly as ascending or descending. The addition ASCENDING or DESCENDING can be used INTO TABLE flights STABLE BY cityfrom cityto. Stable sorting of the internal table flights by columns cityfrom cityto, whereby the order within this sorting with respect to carrid and connid is preserved. Multiple sorting of a table using the same sort key can produce a different order each time the table is sorted.If the addition STABLE is not specified, the order is not stable: Of lines that do not differ in the sort key remains unchanged in the sort. STABLE is used to achieve stable sorting, which means that the relative order Sorting Internal Tables with Secondary Keys.The hashed tableĬarriers is sorted by its primary key, that is by the column carrid. Simplest form of the statement SORT for internal tables. The system class CL_ABAP_ITAB_UTILITIESĬontains method VIRTUAL_SORT, which can be used to virtually sort a set of internal tables.A non-initial, invalid reference leads to a runtime error if it is involved in sorting. An internal table can only be sorted by valid or initial references. Rule is defined for non-initial invalid references. Here, it is important to note that no comparison Reference types but doing this is questionable. These can be used as an extension to the statement SORT if its sort criteria are not sufficient (see the Has the additions ASCENDING and DESCENDING for Sorting using SORT does not affect the assignment of lines to a secondary table index.Secondary table keys cannot be specified as sort keys.The standard key of a standard table can be empty.If the line type is structured, the table is sorted by all character-like and byte-like components.When using the primary table key, it should be noted that this key can be the standard key, which can also have unexpected consequences:.Standard key, makes a program difficult to understand and possibly unpredictable. Primary table key, which can itself, in standard tables, be defined implicitly as a It is best to specify an explicit sort key behind BY, if possible.Otherwise, the statement SORT is ignored for sorted tables. if an attribute of an object is specified as a component in the addition BY.if the addition BY is used to specify a different sort key as the initial part of the table key.The latter occurs in the following cases: If it is not determined until runtime that a sorted table is to be sorted, an uncatchable exception is raised if this action could modify the existing sorting. Sorted tables cannot be sorted using SORT and applying the statement SORT toīy the syntax. LOOP runs without the addition USING KEY. In both table categories, SORT specifies the order in which a subsequent This internal order was defined either by inserting lines into the internal table or by a previous sort using the statement SORT. In hashed tables, the internal order is modified.In standard tables, the primary table index is applied in accordance with the sort order.The addition STABLE can be used for stable sorting. The order can be different depending on the platform or when sorted multiple times. Keys is not preserved when they are sorted. Sorting is unstable by default, which means that the relative order of lines that do not differ in sort If this is known statically, the syntax check produces a warning. ![]() If the primary table key of a standard table isĮmpty, no sort takes place. Keys, the sort is prioritized according to the order of the key fields in the line type of the table. Key fields are specified in the table definition. The priority of the sort depends on the order in which the If no explicit sort key is specified using the addition BY, the internal table itab is sorted by the
