![]() ![]() Cause: Illegal assignment to the LOOP-Reference in the core of the loop.Cause: Illegal Conversion of the LOOP-Field symbol in the core of the loop.The following loop deletes all lines of an internal table since - through the short form of theĭELETE statement - the current first line is always deleted. PARAMETERS p_name TYPE scarr-carrname DEFAULT '*'.ĭATA: scarr_tab TYPE SORTED TABLE OF scarr The contents of the current row for the outer loop are analyzed in the WHERE-condition for the inner loop. Garbage Collector, as long as the loop is not completed. The respective object cannot be deleted from the Possible changes of the reference variable do not have an effect on the loop. Is processed completely at the table referenced at entry. If you specify the internal table itab through a REFRESH, SORT and all types of assignments to itab are not allowed. LOOP using statements that access the entire table. Within classes, you cannot change table itab in the statement block of the This affects sy-tabix in the subsequent loop pass. If you delete lines in front of the current line, the internal loop counter is decreased by one withĮach deleted line. If you insert lines in front of the current line, the internal loop counter is increased by one withĮach inserted line. ![]() If you delete lines behind the current line, the deleted lines will no longer be processed in the subsequent loop passes. If you insert lines behind the current line, these new lines will be processed in the subsequent loop passes. If you insert or delete lines in the statement block of a LOOP, this will have the following effects: The system fields sy-tfill and sy-tleng are also supplied with data. Is reset to the value it had before the loop was entered, and the following applies sy-subrc: The LOOP ATstatement sets system field sy-tabix to the table index of the current table line for If no appropriate lines are found or if the internal table is blank, the loop is not run at all. The loop continues to run until all the table lines that meet condititionĬond have been read or until it is exited with a statement. In the table, and in the sort sequence following use of the SORT statement. The lines are processed in the sequence in which they were inserted The lines are read by ascending table index. The sequence in which the lines are read depends on the table type: To exit processing of the statement block, you can use the statements described in Section leave loops. Result determines when and where the line contents are read.ĮNDLOOP is executed once for each line. ![]() You can either read all the lines or specify conditionsĬond to restrict which lines to read. Statement reads lines from internal table itab sequentially. If an internal table has the same name as a database table, a statement like this accesses the internal table.Statements define a loop around a statement block. The statement DELETE FROM dbtab has the statement DELETE FROM itab with identical syntax. The number of rows that can be deleted from the tables of a database within aĭatabase LUW is limited, since a database system can only manage a limited amount of locks and data in the rollback area. SAP ABAP - Deleting Internal Tables - TutorialsPoint WebThe delete operation is performed on the basis of a default key that could be taken from the work. Isolation level defines whether the deleted data can be read into otherĭatabase LUWs before or only after the database commit.ĭatabase lock until the next database commit or rollback. Until that point, they can still be undone using a The rows are deleted permanently from the database table in the nextĭatabase commit. If an overflow occurs because the number or rows is greater than 2,147,483,647, sy-dbcnt is set to -1. The statement DELETE sets sy-dbcnt to the number If no conditions were specified, no rows were deleted, since the database table was already empty. In the second part, you're performing a READ TABLE on a standard table (itab). When an internal table in source wasĭeclared, not all of the specified rows were deleted. select from bseg into corresponding fields of itab for all entries in itbkpf where bukrs itbkpf-bukrs and belnr itbkpf-belnr and gjahr itbkpf-gjahr. When a WHERE condition or a work area in source If no conditions were declared, all rows were deleted. ![]() The declaration of an internal table in source, all declared rows were deleted or the internal table is empty. When a work area in source was declared, the declared row was deleted. When the WHERE condition was declared, at least one row was deleted. The statement DELETE sets the values of the system fields sy-subrc and sy-dbcnt. The rows that are to be deleted are declared either in a WHERE condition The statement DELETE deletes one or more rows from the database table or SAP NetWeaver AS ABAP Release 750, ©Copyright 2016 SAP AG. ![]()
