600 \ h really waste your look at basic grammar and then rely on his own idea to build a library to play

CodePudding user response:

It takes step by step to learn, basic, direct data analysis, it's not bullshit

CodePudding user response:

600/h really waste, if you really want to play the SQL from scratch, that doesn't necessarily

T-sql part is the general, basically all databases are supported, details may be slightly different, but basically identical

To understand the create database, create table, and then understand the select, update, delete, understand the drop, understand the alter

To understand all kinds of the join, all kinds of the apply, query the seeds, various aggregation function and group

Basically, daily development will be enough

CodePudding user response:

After completing the foundation study, they need to be transferred into your actual environment, after all, each database software extension instructions are different

After understanding the database stored procedure, the system function, trigger, queue auxiliary complete development

Understanding index, paging, full text search, execution plan, optimize the database

Understand the disaster recovery, load balance,,,,

Anyway, it basically no head, always have room for improvement
