Question
A column named “Data” contains VARIANT data and stores values as follows:
{
"Employee": {
id: 100,
name: John,
location: "New York"
}
}
How will Snowflake extract the employee’s name from the column data?
A. Data:employee.name
B. DATA:employee.name
C. data:Employee.name
D. data:employee.name
Answer
D. data:employee.name
Explanation
In Snowflake, to extract a value from a VARIANT, OBJECT, or ARRAY column, you use the : operator. The column name and the key are case-sensitive. So, in this case, the column name is data and the key is employee.name. Therefore, data:employee.name is the correct way to extract the employee’s name from the column data.
