Oracle Bulk Insert: Fast Methods Explained
There are two methods for executing batch inserts in Oracle.
- Perform bulk insertions using the INSERT INTO SELECT statement.
INSERT INTO table_name (column1, column2, column3)
SELECT value1, value2, value3 FROM source_table;
This method is suitable for selecting data from another table and inserting it into the target table.
- Use the INSERT ALL statement for bulk insertion:
INSERT ALL
INTO table_name (column1, column2, column3) VALUES (value1, value2, value3)
INTO table_name (column1, column2, column3) VALUES (value4, value5, value6)
SELECT * FROM dual;
This method is suitable for inserting multiple data rows into the target table at once.
Batch insertion can significantly improve the efficiency of inserting data and reduce the overhead of database operations, regardless of the method used.
