## Changing Data in Database Tables
### Using [`INSERT`](https://help.sap.com/doc/abapdocu_cp_index_htm/CLOUD/en-US/index.htm?file=abapinsert_dbtab.htm)
### Using INSERT
- Inserts one or more rows into a database table specified.
- The rows to be inserted are taken from a structure, an internal table, or the result set of an embedded subquery.
- As mentioned above, structures and internal tables from which to insert content should be specified as host variables (with `@`) or host
expressions (with `@( ... )`).
- The system fields `sy-subrc` (0 = single row or all rows inserted successfully, 4 = row not or not all rows inserted) and `sy-dbcnt` (number of rows that are inserted) are set.
- More information: [`INSERT`](https://help.sap.com/doc/abapdocu_cp_index_htm/CLOUD/en-US/index.htm?file=abapinsert_dbtab.htm)
