这段代码是用来将面向对象系统分析与设计实验信计201这门课程的信息插入到数据库中，并且创建相应的实验项目和学生账号。其中，先向tb_Course表中插入课程信息，然后通过游标遍历实验项目的字段，将每个实验项目插入到tb_Project表中。接着，将学生账号信息插入到tb_User表中，并将学生选课信息插入到tb_SC表中。

在 SQL Server 中，可以使用 GO 命令将 SQL 脚本分段执行。GO 命令用于将脚本中的多个批次分隔开来，每个批次之间用 GO 分隔符分隔。例如，你可以将存储过程的创建脚本和执行脚本分别放在两个批次中，然后用 GO 分隔符分隔开来，如下所示：

-- 创建存储过程
CREATE PROCEDURE add_data
    @course_id varchar(200),
    @table_name varchar(200),
    @teacher_id varchar(200)
AS
BEGIN
    -- 存储过程代码
END
GO

-- 执行存储过程
EXEC add_data '面向对象系统分析与设计实验信计201','面向对象系统分析与设计实验信计201','101001'
GO

注意，GO 命令不能作为 T-SQL 语句的一部分，它只是 SQL Server Management Studio 和 sqlcmd 工具中的一个批处理命令。在使用 GO 命令时，要确保每个批次的语法都是正确的，否则会导致执行失败。

def add_audit_columns(self, dataframe, write_params): try: print(write_params) audit_source_sys_name = write_params.get("audit_src_sys_name", "") or write_params.get( "table_full_name") or write_params.get("data_source_name", "") print("audit_source_sys_name - " + audit_source_sys_name) if ("audit_src_sys_name".upper() in (name.upper() for name in dataframe.columns)): print("audit_src_sys_name column is present. Adding present layer details....") audit_dataframe = DataSink_with_audit(self.spark).add_audit_col_append(dataframe, audit_source_sys_name, write_params) print("Tables is updated.") else: print("Adding column - audit_src_sys_name.") audit_dataframe = DataSink_with_audit(self.spark).add_audit_col_fill(dataframe, audit_source_sys_name, write_params) print("audit_src_sys_name added.") print("Added Audit Cols") return audit_dataframe except Exception as e: raise Exception("job failed with error {}".format(e))

根据您提供的Python函数，我为您编写了一个MySQL存储过程的示例，但是需要根据您的具体需求进行修改和调整。这个存储过程的功能是向数据表中添加一个名为audit_src_sys_name的列，同时向这个列中填充相应的值。

CREATE PROCEDURE add_audit_columns(
    IN df_column_names VARCHAR(255),
    IN df_values VARCHAR(255),
    IN write_params TEXT,
    OUT audit_dataframe TEXT
)
BEGIN
    DECLARE audit_source_sys_name VARCHAR(255);
    DECLARE column_present BOOLEAN;
    DECLARE sql_stmt TEXT;
    
    SET audit_source_sys_name = JSON_EXTRACT(write_params, '$.audit_src_sys_name');
    IF audit_source_sys_name IS NULL OR audit_source_sys_name = '' THEN
        SET audit_source_sys_name = JSON_EXTRACT(write_params, '$.table_full_name');
    END IF;
    
    SET column_present = FALSE;
    SET sql_stmt = CONCAT('SELECT COUNT(*) INTO @exists FROM information_schema.columns WHERE table_name = \'', df_column_names, '\' AND column_name = \'audit_src_sys_name\'');
    PREPARE stmt FROM sql_stmt;
    EXECUTE stmt;
    DEALLOCATE PREPARE stmt;
    
    IF @exists > 0 THEN
        SET column_present = TRUE;
        SET sql_stmt = CONCAT('UPDATE ', df_column_names, ' SET audit_src_sys_name = \'', audit_source_sys_name, '\'');
    ELSE
        SET sql_stmt = CONCAT('ALTER TABLE ', df_column_names, ' ADD COLUMN audit_src_sys_name VARCHAR(255) DEFAULT NULL AFTER ', df_values);
        PREPARE stmt FROM sql_stmt;
        EXECUTE stmt;
        DEALLOCATE PREPARE stmt;
    END IF;
    
    IF column_present THEN
        SET audit_dataframe = CONCAT('Audit source system name column is present. Adding present layer details....\n');
        SET sql_stmt = CONCAT('UPDATE ', df_column_names, ' SET audit_src_sys_name = CONCAT(audit_src_sys_name, \', \', \'', audit_source_sys_name, '\')');
    ELSE
        SET audit_dataframe = CONCAT('Adding column - audit_src_sys_name.\n');
        SET sql_stmt = CONCAT('UPDATE ', df_column_names, ' SET audit_src_sys_name = \'', audit_source_sys_name, '\'');
    END IF;
    
    PREPARE stmt FROM sql_stmt;
    EXECUTE stmt;
    DEALLOCATE PREPARE stmt;
    
    SET audit_dataframe = CONCAT(audit_dataframe, 'Tables is updated.\n');
END

这个存储过程的输入参数包括数据表的列名、值、以及一个JSON格式的字符串write_params，其中包含各种写入参数信息。输出参数是一个JSON格式的字符串audit_dataframe，包含存储过程的执行结果信息。请注意，这只是一个示例，您需要根据实际情况进行修改和调整。
