如何在Google电子表格的Google App脚本中将数组传递到查询字符串中

Question

I have a script that will take a query in the form of a string variable (named sql ) and pull data from BigQuery to a Google Spreadsheet. Something like below:

var sql = "SELECT field1, field2 FROM table";
var queryResults;

try {
var queryRequest = BigQuery.newQueryRequest();
queryRequest.setQuery(sql).setTimeoutMs(100000).setUseLegacySql(false);
queryResults = BigQuery.Jobs.query(queryRequest, projectNumber);
}

Now, I want to create an array variable and pass it to the sql query string. When I pass the array as a variable like below, it didn't work: Google SpreadSheet gave me an error:

GoogleJsonResponseException: Unrecognized name: becca at [1:1088]
("becca" is the first value of my array)

var array = ['a','b','c']
var sql = "SELECT field1 FROM UNNEST("+array+") AS field1";

It only worked when I manually hard code the array of strings, like below:

var sql = "SELECT field1 FROM UNNEST(['a','b','c']) AS field1";

However my array is supposed to be dynamic so manually hard coding it is not an option. How do I pass it as a variable then?

Answer 1

you are passing the array type in the string format which will create a problem. you need to convert the array variables in such array formatted string format.

var arrStr=arr.join("','");
"SELECT field1 FROM UNNEST(['"+arrStr+"']) AS field1"
