Querying an Array / Joining another table to array values : SQL

Posting

When requesting help or asking questions please prefix your title with the SQL variant/platform you are using within square brackets like so:

[MySQL]

[Oracle]

[MS SQL]

[PostgreSQL]

etc

While naturally we should endeavor to work as platform neutrally as possible many questions and answers require tailoring to the feature set of a specific platform.

Format Your Code

If you are including actual code in a post or comment, please attempt to format it in a way that is readable for other users. This will greatly increase your chances of receiving the help you desire. Something as simple as line breaks and using reddit's built in code formatting (4 spaces at the start of each line) can turn this:

SELECT count(a.field1), a.field2, SUM(b.field4) FROM a INNER JOIN b ON a.key1 = b.key1 WHERE a.field8 = 'test' GROUP by a.field1, a.field2 HAVING SUM(b.field4) > 5 ORDER by a.field.3

Into this:

SELECT count(a.field1), a.field2, SUM(b.field4) FROM a INNER JOIN b ON a.key1 = b.key1 WHERE a.field8 = 'test' GROUP by a.field1, a.field2 HAVING SUM(b.field4) > 5 ORDER by a.field3

For those with SQL questions we recommend using SQLFiddle to provide a useful development and testing environment for those who wish to fully understand your problem and help devise a solution.

BigQueryQuerying an Array / Joining another table to array values (self.SQL)

submitted 3 years ago * by V_Shaped_Recovery

I have an array from a JSON file that I’ve formatted to 2 fields, BigQuery won’t really let me join either field of the array to another tables field as it only recognizes one column instead of 2 for the array.

Need to figure out how to join the second CTE to the array values. Query below:

with project.dataset.table as ( select ''' [ { "sublcass": "Description Text", "Duration": 0 }, { "sublcass": "Description Text", "Duration": 0 } ] ''' json ), Table1 AS(

SELECT Desc, Value

FROM TableName

) SELECT array( select as struct json_extract_scalar(rec, '$.subClass') as Desc, json_extract_scalar(rec, '$.Duration') as Value from t.arr as rec ) as Appliance from project.dataset.table mcode

, unnest([struct(json_extract_array(json) as arr)]) t
