AS array_length:Names the function's output for easy reference, showing that this order contains three items. The example's output would be a single integer value representing the number of elements in the array. In this case, the array [1, 2, 3] has three components. This indicates that...
UNNEST: This function is used to expand an array into a set of rows. It takes an array column and returns a row for each element in the array. array_column:This is the name of the column that contains array data. AS element: This assigns an alias (element) to each element in the ...
While this data is very operable in its current form, we highly recommend using Array or Object Nodes to parse the data. BigQuery does also include the schema object in the response, so you can also verify that your data matches the schema. Step 5: Using your Data in BigQuery...
BREAKING CHANGE Previously when polling a BigQuery Job the Node.js client would check for the presence of the errors field when trying to determine if the job suceeded. We have since changed this logic to instead check for the errorResult field. This is significant because the errors array ...

Repeated— The field contains an array of values of the specified data type instead of a single value. Hands-on BigQuery After defining the absolute basics one should know before getting started with BigQuery, we will now set up a small BigQuery project using Node.js.Since this is an article...
column_options: advanced: an array of options for columns name: column name type: BigQuery type such as BOOLEAN, INTEGER, FLOAT, STRING, TIMESTAMP, DATETIME, DATE, and RECORD. See belows for supported conversion type. boolean: BOOLEAN, STRING (default: BOOLEAN) long: BOOLEAN, INTEGER, ...
you should verify the value of every row to ensure that the data type for each column is correct. For example, it is possible that a column contains integers except for a handful of rows that have floats. If so, then it’s quite likely that the autodetect will detect the column as be...

You can also just add single fields in the customDbIndexes, so if you look below the on-chain field amount1Out is not indexed so an index will not be automatically created but without an index it will be very slow so just add it in the array of customDbIndexes. "decodeAbiItems": [...
