... FOR ALL ENTRIES IN @itab WHERE ... col operator @itab-comp ...


If the addition FOR ALL ENTRIES is specified in front of the language element WHERE of the statement SELECT of a main query, the components comp of the internal table itab specified here can be used within sql_cond on the right side of comparisons of a relational operator in comparisons with a column col. The specified component comp must be compatible with the column col. The internal table itab can have a structured or an elementary row type. For an elementary row type, the pseudo component table_line must be specified for comp. The name of the host variable dbcur should be prefixed with the escape character @.

The entire logical expression sql_cond is evaluated for each individual row of the internal table itab. The results set of the SELECT statement is the union set of the results sets produced by the individual evaluations. Rows that appear in duplicate are removed from the results set automatically. If the internal table itab is empty, the entire WHERE condition is ignored and all rows from the database are placed in the results set.

The logical expression sql_cond of the WHERE condition can comprise multiple logical expressions using AND and OR. However, if FOR ALL ENTRIES is specified, there must be at least one comparison with a column of the internal table itab that can be specified statically or dynamically.

The following restrictions apply when using the addition FOR ALL ENTRIES with other additions:


In all other cases, SAP buffering is used and the addition FOR ALL ENTRIES can be a more efficient alternative to join expressions.


Gets all flight data for a specified departure city. The relevant airlines and flight numbers are first passed to an internal table entry_tab, which is evaluated in the WHERE condition of the subsequent SELECT statement. This selection could also be carried out in a single SELECT statement by using a join in the FROM clause. Make sure that the table entry_tab is not initial before the SELECT statement is executed using FOR ALL ENTRIES.
