在Databricks SQL 中,從 Databricks Runtime 12.2 開始,這個子句已被取代。 您應該將表格值生成器函數作為table_reference來使用。 語法 LATERAL VIEW [ OUTER ] generator_function ( expression [, ...] ) [ table_identifier ] AS column_identifier [, ...] ...
In SQL, a view is a virtual table based on the result-set of an SQL statement. A view contains rows and columns, just like a real table. The fields in a view are fields from one or more real tables in the database. You can add SQL statements and functions to a view and present...
2. We can use a single SQL query to accomplish what we want. Notice that we treat the inline view exactly the same as we treat a table. Comparing Query 2 and Query 3, we see that the only difference is that we replace the temporary table name in Query 2 with the inline view stat...
TABLE_SCHEMA nvarchar(128) 包含基表的架构的名称。 重要说明:查找对象架构的唯一可靠的方式是查询 sys.objects 目录视图。 TABLE_NAME sysname 用作视图基础的基表。 另请参阅 系统视图 (Transact-SQL) 信息架构视图 (Transact-SQL) sys.sql_dependencies (Transact-SQL) sys.objects (Transact-SQL) sys.views...
Hive必会SQL语法Explode 和 Lateral View 在业务系统中是存贮在非关系型数据库中,用json存储的概率比较大,直接导入hive为基础的数仓系统中,就需要经过ETL过程解析这类数据,explode与lateral view在这种场景下大显身手。 本文转载自微信公众号「Java大数据与数据仓库」,作者刘不二。转载本文请联系Java大数据与数据仓库...
