Hi,
You can use SQL statements, either interactively or within source code, to access and retrieve data that is stored in the database. You use the following statements for data manipulation:
select – Select the data to modify.
insert – Add one or more new records to a table.
update – Modify data in existing table records.
delete – Remove existing records from a table.
Before any data can be changed, you must use a select statement to select the data to update. The select forUpdate command selects records for update only. The insert, update, and delete statements perform operations on one record at a time. The array insert, insert_recordset, RecordInsertList, and update_recordset statements perform operations on multiple records at the same time.
