FETCH Short Reference
ABAP_SYNTAX FETCH NEXT CURSOR dbcur INTO$|APPENDING ....
What does it do? The AB-SQL statement FETCH takes the rows requested by the INTO or APPENDING addition from the result set of the database cursor linked with the cursor variable dbcur from the current cursor position and assigns them to the data objects specified there. The cursor variable dbcur must be a host variable declared with the special predefined data type cursor, which was opened with the statement OPEN CURSOR or that was assigned an open cursor. Otherwise, a catchable exception of the class CX_SY_OPEN_SQL_DB is raised. The syntax and meaning of the addition INTO or APPENDING are the same as the identically named additions of the SELECT statement, with the exception that no inline declarations can be made there without the addition NEW and no LOB handles can be created. BEGIN_SECTION SAP_INTERNAL_HINT LOB Handles will be supported in a later release but not for WITH HOLD. END_SECTION SAP_INTERNAL_HINT If non-table-like data objects are specified after INTO, one row is extracted. If an internal table is specified after INTO or APPENDING, either all rows are extracted or as many as specified in the addition PACKAGE SIZE. The statement FETCH moves the position of the database cursor that is linked with dbcur by the number of extracted rows to the next row to be extracted. If the last row of the result set was extracted in a FETCH statement, each subsequent FETCH statement in which dbcur is linked with the same database cursor sets sy-subrc to 4, without affecting the data objects specified after INTO or APPENDING. System Fields The statement FETCH sets the values of the system fields sy-subrc and sy-dbcnt. sy-subrcMeaning 0At least one row was extracted from the result set. 4No row was extracted. After every row extraction, the statement FETCH sets sy-dbcnt to the number of rows extracted so far from the relevant result set. If an overflow occurs because the number or rows is greater than 2,147 ,483,647, sy-dbcnt is set to -1. If no row can be extracted, sy-dbcnt is set to 0.
