When reading data in the cursor in Pro * C in batches, note: when reading data in the cursor in batches at the last time, the data is retrieved to hostarray, and sqlca. sqlcode is set to 1403 (no_data_found ). If you determine sqlca. sqlcode immediately after fetch, the last data may not be retrieved. The insurance method is to define the number of last read records for a variable record: If (sqlca.

pointer and read the current record. Use the fetch statement to forward the cursor pointer to a record and read the current record in the buffer to the variable. The fetch statement is usually used in a cyclic structure. The fetch statement is executed cyclically to retrieve rows in the result set one by one for processing. In many databases, the cursor pointer can be easily understood at any step in any direction, not just forward the cursor pointer to a row.Fetch 4. Close the cursor. Close t

Problem: when using an implicit cursor like select into from tablename, if no data is found, an error in the ora-01403 is reported. Each time an explicit cursor is used, it is very troublesome to open the value. An experienced instructor suggested using aggregate functions like max min to avoid exceptions caused by select into and the trouble of using cursors each time. Efficiency and feasibility tests: ① Temporary table Create table edu. TEST(ID NUMBER NULL)TABLESPACE EDUCATIONNOLOGGINGPCTFREE
