Inserting One or Multiple Rows into a Table from Oracle in Python

Summary: in this tutorial, you will learn how to use the Python cx_Oracle API to insert data into a table from an Oracle Database.

Inserting a single row into the table

The following code illustrates how to insert a new row into the billing_headers table:

import cx_Oracle import config as cfg from datetime import datetime def insert_billing (billing_date, amount, customer_id, note) : “”” Insert a row to the billing_headers table :param billing_date: :param amount: :param customer_id: :param note: :return: “”” sql = ( ‘insert into billing_headers(billing_date, amount, customer_id, note) ‘ ‘values(:billing_date,:amount,:customer_id,:note)’ ) try : with cx_Oracle.connect(cfg.username, cfg.password, cfg.dsn, encoding=cfg.encoding) as connection: with connection.cursor() as cursor: cursor.execute(sql, [billing_date, amount, customer_id, note]) connection.commit() except cx_Oracle.Error as error: print( ‘Error occurred:’ ) print(error) if __name__ == ‘__main__’ : insert_billing(datetime.now(), 1200 , 1 , None ) Code language: Python ( python )

In the insert_billing() function:

First, construct an insert statement that inserts a new row into the billing_headers table. This insert statement uses the named bind variables.

Second, connect to the Oracle Database with the information provided by the config.py module:

If you have not followed the previous tutorial, you can create the config.py module with the following code:

username = ‘OT’ password = ‘‘ dsn = ‘localhost/pdborcl’ port = 1512 encoding = ‘UTF-8’ Code language: Python ( python )

Third, create a Cursor object from the Connection object and execute the insert statement.

Finally, commit the transaction by using the Connection.commit() method:

connection.commit() Code language: Python ( python )

The following function call inserts a new row into the billing_headers table:

insert_billing(datetime.now(), 1200 , 1 , None ) Code language: Python ( python )

After executing the program, you can query the billing_headers table using any Oracle client tool such as SQL*Plus and SQL Developer.

SELECT * FROM billing_headders; Code language: SQL (Structured Query Language) ( sql )

It worked as expected.

Inserting multiple rows into the table

If you want to insert multiple rows into a table once, you can use the Cursor.executemany() method.

The Cursor.executemany() is more efficient than calling the Cursor.execute() method multiple times because it reduces network transfer and database load.

The following code illustrates how to insert multiple rows into the billing_headers table:

import cx_Oracle import config as cfg from datetime import datetime def insert_billings (billings) : “”” insert multiple billings :param billings: a list of billings :return: “”” sql = ( ‘insert into billing_headers(billing_date, amount, customer_id, note) ‘ ‘values(:billing_date,:amount,:customer_id,:note)’ ) try : with cx_Oracle.connect(cfg.username, cfg.password, cfg.dsn, encoding=cfg.encoding) as connection: with connection.cursor() as cursor: cursor.executemany(sql, billings) connection.commit() except cx_Oracle.Error as error: print( ‘Error occurred:’ ) print(error) if __name__ == ‘__main__’ : billing_docs = [ (datetime.now(), 1000 , 1 , None ), (datetime.now(), 1500 , 2 , None ), (datetime.now(), 1700 , 3 , None ), ] insert_billings(billing_docs) Code language: Python ( python )

Here are the contents of the billing_headers table after executing the program:

SELECT * FROM billing_headders; Code language: SQL (Structured Query Language) ( sql )

In this tutorial, you have learned how to use the cursor.execute() and Cursor.executemany() methods to insert one or more rows into a table in the Oracle Database.

Python(파이썬)과 Oracle(오라클) 연동-CRUD

1. oracle(오라클)에서 테이블 생성

CREATE TABLE SAMPLE( COL01 VARCHAR2(20), COL02 VARCHAR2(20), COL03 VARCHAR2(20) CONSTRAINT SAMPLE_PK PRIMARY KEY (COL01) );

2. select

import cx_Oracle conn = cx_Oracle.connect(‘사용자이름/비밀번호@localhost:1521/xe’) cs = conn.cursor() –cursor => 쿼리문에 의해 반환되는 결과값을 저장하는 메모리 공간 rs = cs.execute(“select col01,col02,col03 from sample”) for record in rs: print(record[0]) cs.close() conn.close()

3. insert

import cx_Oracle conn = cx_Oracle.connect(‘사용자이름/비밀번호@localhost:1521/xe’) cs = conn.cursor() sql = “insert into sample (col01,col02,col03) values (:1,:2,:3)” cs.execute(sql,(‘3′,’3′,’3’)) –execute => sql문 실행 print(cs.rowcount) cs.close() conn.commit() conn.close()

4. update

import cx_Oracle conn = cx_Oracle.connect(‘사용자이름/비밀번호@localhost:1521/xe’) cs = conn.cursor() sql = “update sample set col02 = :1 , col03 = :2 WHERE col01=:3” cs.execute(sql,(‘3′,’3′,’1’)) # cs.rowcount : java에서의 cnt print(cs.rowcount) cs.close() conn.commit() conn.close()

5. delete

import cx_Oracle conn = cx_Oracle.connect(‘사용자이름/비밀번호@localhost:1521/xe’) cs = conn.cursor() sql = “delete from sample where col01=:1” cs.execute(sql,(‘1’)) print(cs.rowcount) cs.close() conn.commit() conn.close()

Insert values to the oracle table using python cx_oracle Session Pool

I can see two problems with your code.

The first is that you are not calling cursor.execute correctly. You are creating a tuple in the line

sql=(“insert into exm(id,name) values(:1, :2)”, rows)

which you then pass to

cursor.execute(sql)

This has the same effect of running the following line (note the extra parentheses):

cursor.execute((“insert into exm(id,name) values(:1, :2)”, rows))

when you really want to run this line, which doesn’t have the extra parentheses:

cursor.execute(“insert into exm(id,name) values(:1, :2)”, rows)

I would recommend that you instead set sql to just the SQL string to run against the database, and pass rows to cursor.execute separately.

sql=”insert into exm(id,name) values(:1, :2)” cursor.execute(sql, rows)

The second problem is that you seem to want to insert multiple rows at the same time. You hint at this by naming your variable rows and assigning a 1-element list of tuples to it. To insert multiple rows at the same time, you need to use cursor.executemany , not cursor.execute :
