Question

我使用robotframework DatabaseLibrary，JayDeBeApi，MS SQL Server JDBC驱动程序设置了机器人框架测试，并且连接成功。但是我得到 SQLServerException：当运行任何sql时，当AutoCommit模式设置为＆＃34; true＆＃34; 时，无法调用回滚操作。

我尝试通过添加＆＃34; autoCommit = false＆＃34;来关闭AutoCommit。在jdbc连接url上或添加＆＃34; SET IMPLICIT_TRANSACTIONS ON＆＃34;在SQL语句中，甚至在SQL Server Management Studio上检查SET IMPLICIT_TRANSACTIONS ANSI选项，但是没有任何运气。

这是robotframework maven插件设置

的pom.xml

    <groupId>org.robotframework</groupId>

    <version>1.4.5</version>

这是我在运行机器人测试时遇到的错误

Test Prepare Data :: Reset Data...        | FAIL |
DatabaseError: com.microsoft.sqlserver.jdbc.SQLServerException: Cannot invoke a rollback operation when the AutoCommit mode is set to "true".

我在这方面采取的一个重大解决方案是修改robotframework DatabaseLibary connection_manager.py，并在jaydebeapi连接上将autoCommit设置为false，如下面的 self._dbconnection.jconn.setAutoCommit（False），但我希望知道比如果有更好的解决方案。

{your python virtualenv} /site-packages/DatabaseLibrary/connection_manager.py

import ConfigParser
from robot.api import logger

class ConnectionManager(object):
    """
    Connection Manager handles the connection & disconnection to the database.
    """




    def connect_to_database_using_custom_params(self, dbapiModuleName=None, db_connect_string=''):
        """
        Loads the DB API 2.0 module given `dbapiModuleName` then uses it to 
        connect to the database using the map string `db_custom_param_string`.

        Example usage:
        | # for psycopg2 |
        | Connect To Database Using Custom Params | psycopg2 | database='my_db_test', user='postgres', password='s3cr3t', host='tiger.foobar.com', port=5432 |

        | # for JayDeBeApi | 
        | Connect To Database Using Custom Params | JayDeBeApi | 'oracle.jdbc.driver.OracleDriver', 'my_db_test', 'system', 's3cr3t' |
        """
        db_api_2 = __import__(dbapiModuleName)

        db_connect_string = 'db_api_2.connect(%s)' % db_connect_string

        self._dbconnection = eval(db_connect_string)
        self._dbconnection.jconn.setAutoCommit(False)

Answer 1

前段时间我也确实遇到过这个问题，但是我记得它在url中使用了autocommit（例子来自我的解决方案）：

Connect To Database Using Custom Params    jaydebeapi     'net.sourceforge.jtds.jdbc.Driver', ['jdbc:jtds:sqlserver://${DB_HOST}:${DB_PORT}/${database};autocommit=false','${DB_USER}','${DB_PASSWORD}'],${jdbcDriver}

但不幸的是，它不能用于oracle，我必须像你一样修改库。

Answer 2

您还可以在DatabaseLibrary实例中将autocommit设置为false：

Connect To Database Using Custom Params    jaydebeapi    'oracle.jdbc.driver.OracleDriver', 'jdbc:oracle:thin:@oracle.database.com:1234/foo', ['username_here', 'password_here'], '${CURDIR}/databasedrivers/ojdbc8.jar'
${DatabaseLibrary}    Get library instance    DatabaseLibrary
Evaluate    $DatabaseLibrary._dbconnection.jconn.setAutoCommit(False)

Robotframework + JayDeBeApi + SQLServer提供SQLServerException：当AutoCommit模式设置为＆＃34; true＆＃34;
