PLS-00115: this PRAGMA must follow the declaration of 'string'

PLS-00115: this PRAGMA must follow the declaration of 'string'
Cause: The pragma refers to a PL/SQL object that was not declared or is not within the scope of the reference. Identifiers must be declared before they are used in a pragma; forward references are not allowed.
Action: Check the spelling and declaration of the identifier. Also confirm that the declaration is placed correctly in the block structure.

.原因: pragma是指未声明或不在引用范围内的PL / SQL对象。标识符必须在使用pragma之前被声明; 不允许转发参考。,
.操作:检查标识符的拼写和声明。同时确认声明在块结构中正确放置。,
