CALL STATEMENT

我的收藏

这里只有在使用 Spark 中使用 Iceberg SQL 扩展 时，存储过程才可用。
语法
CALL expression
参数
expression：函数表达式。
示例
CALL catalog_name.`system`.procedure_name(arg_name_2 => arg_2, arg_name_1 => arg_1)
﻿
#当按位置传递参数时，如果它们是可选的，则只能省略结束参数。
CALL catalog_name.system.procedure_name(arg_1, arg_2, ... arg_n)
﻿
#将当前快照设置为db.sample1：
CALL catalog_name.system.set_current_snapshot('db.sample', 1)
更多使用
Spark Procedures。
