SELECT INTO Statements
You can use the SELECT INTO statement to export formatted data to a file.
Data Export with an SQL Query
The following query exports data into a file formatted in comma-separated values (CSV):
boolean ret = stat.execute("SELECT Type, DatasetName INTO "csv://c:/Schemas.txt" FROM "Schemas" WHERE ProjectId = 'bigquery-public-data'"); System.out.println(stat.getUpdateCount()+" rows affected");You can specify other file formats in the URI. The following example exports tab-separated values:
Statement stat = conn.createStatement(); boolean ret = stat.execute("SELECT * INTO "Schemas" IN 'csv://filename=c:/Schemas.csv;delimiter=tab' FROM "Schemas" WHERE ProjectId = 'bigquery-public-data'"); System.out.println(stat.getUpdateCount()+" rows affected");
