如何在 CREATE TABLE DDL 中添加列描述
How to add column description in CREATE TABLE DDL
我想向我在 BigQuery 中创建的 table 添加列描述。
当我尝试执行以下查询时:
CREATE TABLE mydataset.newtable (
x STRING(10) "denotes value of x",
y STRING(10) "denotes value of y",
z BIGNUMERIC(35) "denotes value of z"
) AS (SELECT x, y, z FROM table2)
我收到一个错误:
Syntax error: Expected ")" or "," but got string literal "denotes value of x"
我错过了什么?
根据 the documentation 这应该有效:
CREATE TABLE mydataset.newtable (
x STRING(10) OPTIONS(description="denotes value of x"),
y STRING(10) OPTIONS(description="denotes value of y"),
z BIGNUMERIC(35) OPTIONS(description="denotes value of z")
)
