本文档详细介绍了Redshift和MaxCompute之间SQL语法的异同。这篇文档有助于加快sql任务迁移到MaxCompute。由于Redshift和MaxCompute之间语法存在很多差异,因此我们需要修改Redshift上编写的脚本,然后才能在MaxCompute中使用,因为服务之间的SQL方言不同。 2.迁移前RedShift于MaxCompute的各项对比差异 ...
主要区别 2.1.3复合表达式 2.1.4条件比较 2.1.5DDL语法 主要差异: 1.MaxCompute不支持主键自增和PRIMARY KEY 2.指定默认值default]不支持使用函数 3.decimal指定默认值不支持-1 2.1.6DML语法差异 2.1.7内建函数对比 其他未列出的redshift函数不支持。
