我使用robotframework DatabaseLibrary、JayDeBeApi、MS SQL Server JDBC 驱动程序设置robotframework 测试并成功连接。但是，当运行任何 sql 时，当 AutoCommit 模式设置为“true”时，我得到SQLServerException：无法调用回滚操作。

我尝试通过在 jdbc 连接 url 上添加“autoCommit=false”或在 sql 语句中添加“SET IMPLICIT_TRANSACTIONS ON”甚至检查 SQL Server Management Studio 上的 SET IMPLICIT_TRANSACTIONS ANSI 选项来关闭 AutoCommit，但这些尝试都没有运气。

这是robotframework maven插件设置

pom.xml

这是我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".

我对此所做的一个激进的解决方案是修改robotframework DatabaseLibary connection_manager.py，将jaydebeapi连接上的autoCommit设置为false，如下面的self._dbconnection.jconn.setAutoCommit(False)，但如果有的话，我希望知道比这更好的解决方案。

{你的 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)

您还可以在 DatabaseLibrary 实例中设置 autocommit 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)

前段时间我也遇到过这个问题，但我记得它与 url 中的自动提交一起工作（来自我的解决方案的示例）：

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，它不适用于 oracle，我不得不像你一样修改库。
