I have to extract data daily from big query. There is a new table created daily with the timestamp in it.
for example [dw-bigquery:45234.ga_table_20170626]
I am using a context variable which receives the date from a table in YYYY-mm-dd format.
Following is my query.
select * from
'[dw-bigquery:45234.ga_table_' +TalendDate.formatDate("yyyyMMdd", context.load_date)+ ']'
I get an error for invalid assignment operator.
"select * from [dw-bigquery:45234.ga_table_" +TalendDate.formatDate("yyyyMMdd", context.load_date)+ "]"
because each string part must be enclosed between "" (don't know if you need ' and  for big query).
I was still getting errors.
So I made it more simple
"select * from [dw-bigquery:45234.ga_table_" +context.load_date+ "]"
When I run it does not recognise context variable and the table looks like following
