There are no differences in the declarations of local variables, cursors, temporary tables, but on both platforms the order of declaration is important.

在局部变量、游标和临时表的声明方面，两种平台没什么差别，但在这两种平台上，声明的顺序却很重要。

youdao

The declaration clause contains declarative statements that declare local and global variables to be used in subsequent clauses.

声明部分包含声明语句，它们声明后续子句中使用的局部和全局变量。

Also as the name says, implicitly typed local variable, you cannot use var for field declaration or constant variables, therefore following declarations will both produce a compiler error.

故名思意，“隐式类型局部变量”将无法用于域变量或常量的声明中，否则将导致编译错误。
