课程名称:T-SQL 培训与现实场景:交易技巧 课程概述: 此在线 T-SQL 培训课程涵盖了大量实际场景,这些场景是我多年来在 Microsoft SQL Server 技术上实践中获得的经验。我相信这个 Transact SQL 编程与开发的视频教程将加深参与者对 T-SQL 的理解,使其在处理现实情况时更加自信。课程不仅讲解了内容,还针对每个主题涵盖了现实生活中的应用场景。 主要内容包括: - 如何查看表的结构 - 在 SSMS 中创建自己的快捷方式 - 一次删除多个具有固定模式的表 - 执行 DML 操作时的指南 - 如何在 SSMS 中创建解决方案文件及其必要性 - 如何插入已删除的旧身份值行 - 如何重置表的身份 - 如何从表中删除重复记录 - 如何仅选择重复记录 - 使用递归 CTE 查询生成日期维度 - 如何将新更改合并到现有表中 - 存储过程的优势以及 BEGIN 和 COMMIT TRANSACTION 的不足之处 - 如何使用 SQL Server 查询生成运行总计或累积总计 - 如何将当前年份的销售与前一年进行比较 - 如何将当前年份的销售与商业年度开始以来的销售进行比较 - 如何在 SSMS 中的查询窗口之间切换不同的 SQL Server - 如何使用单个 SQL 脚本文件处理不同的 SQL Server - 使用表值存储过程减少往返次数 - SQL Server 中的分页使用 OFFSET-FETCH - SQL Server 中批处理的相关性 - 如何创建和存储自定义错误 - 编写存储过程的指南 主要主题包括: - 深入研究窗口函数 - 排名函数(Rank, Dense_Rank, Row_Number, NTile) - 聚合函数(Sum, Min, Max, Avg, Count) - 分析函数(Lead, Lag, First_Value, Last_Value) - 存储过程的输入参数、输出参数、默认参数及返回表值参数 - 公共表表达式及递归公共表表达式 - 同义词、身份列、事务处理 - 错误处理(Try…Catch) 本课程适合希望通过实践经验提升 T-SQL 技能的开发者,涵盖了实用的技巧与策略,以便在真实的工作环境中得心应手。
In this online T-SQL training course , a lot of real life scenarios are included which i learnt by practicing on Microsoft SQL Server Technology over the years. I believe this Transact SQL Programming & Development video tutorial will deepen the understanding on T-SQL developer and participant will feel more confident in handling real life scenarios. I have covered not only the course contents but also i have covered the real life situations for every topic. Real Life situations are as follow How to view the structure of a table How to create your own shortcuts in SSMS Dropping multiple tables in one go having a fixed pattern Guidelines while performing DML Operations How to create Solution File in SSMS and what is the need for it How to insert a row with old identity value which was deleted How to reset table identity How to delete duplicate records from a table How to select only duplicate records from a table How to produce Date Dimension using Recursive CTE Query How to Merge New Changes to an Existing Table What are the advantages of Stored Procedure BEGIN AND COMMIT TRANSACTION IS NOT SUFFICIENT How to produce running totals or cumulative totals using sql server query How to compare current year sales with the previous year sales How to compare current year sales since the start of the business year sales How to switch between different SQL Servers within a query window in SSMS How to use a single sql script file for different SQL Servers Reducing Roundtrips using Table Valued Stored Procedure Pagination in SQL Server using OFFSET-FETCH BEGIN AND COMMIT TRANSACTION IS NOT SUFFICIENT Relevance of Batch in SQL Server How to create and store customized errors Guidelines of writing a Stored Procedure Following are the major topics covered Deep dive into Window Functions Ranking Functions - (Rank, Dense_Rank Row_Number, NTile ) Aggregate Functions - (Sum,Min,Max,Avg,Count) Analytical Functions-(Lead , Lag, First_Value, Last_Value) Stored Procedures Input Parameters Output Parameters Default Parameters Return Table Valued Parameters Common Table Expressions Recursive Common Table Expressions Synonyms Identity Columns Transactions Raiserror/Throw Error Handling (Try….Catch)
