ABAP_BASIC_FORM_2 OPEN CURSOR [WITH HOLD] dbcur FOR SELECT result FROM source [[FOR ALL ENTRIES IN itab] WHERE sql_cond] [GROUP BY group] [HAVING group_cond] [ORDER BY sort_key]. ABAP Addition ... WITH HOLD What does it do? This statement opens a FOR, and associates a cursor variable dbcur with this database cursor. The result set of the selection can be read with the statement FETCH. dbcur expects a declared variable with the specific predefined cursor. A database cursor dbcur that has already been opened cannot be opened again. A line of the result set is always assigned to an opened database cursor as a cursor position. After the OPEN CURSOR statement, the database cursor is positioned in front of the first line of the result set. After FOR, the syntax of a SELECT statement can be entered which contains all the additions of the normal SELECT statement, except for INTO and APPENDING. In the addition result, the addition SINGLE also cannot be used after SELECT. Only a limited number of database cursors can be open at the same time. An open database cursor can be closed using the statement CLOSE CURSOR. In addition, an open database cursor is closed for a database commit or a database rollback. If a cursor variable dbcur of an open database cursor is assigned to another cursor variable or passed as a parameter, the latter is associated with the same database cursor at the same position. A cursor variable of an open database cursor can also be passed to procedures that have been called externally, to enable the database cursor to be accessed from there. Latest notes: We do not recommend that you assign cursor variables to each other, but rather set them exclusively using the statements OPEN CURSOR and CLOSE CURSOR. If write accesses are made on a database table for which a database cursor is open, the results set is database-specific and undefined. Avoid this kind of parallel access if possible. ABAP Addition What does it do? If the addition WITH HOLD is specified, the Native SQL. Latest notes: The addition WITH HOLD is ignored by implicit database commits, by commits produced by the statement COMMIT WORK, or by any rollbacks that always close the database cursor. A Native SQL database commit can be performed using the DB_COMMIT function module, for example. WITH HOLD angegeben ist, dürfen in der INTO FETCH keine LOB-Handles erzeugt werden. Return to menu
