Is it possible to make a Partitioned table Non-partitioned in BigQuery? - google-bigquery

Question

Given there is a Partitioned table in BigQuery, is it possible to make it non-partitioned?

Answer 1

AFAIK there is no feature/function to unpartition a partitioned table. However, there's nothing stopping you doing a select * from partitioned_table and writing to results to a new (non-partitioned table). Using this approach you'll of course take a hit on cost.
Another way could be to export your table(s) to GCS and then load the exported file(s) back in. Loading doesn't cost anything, so you'd only pay for the brief amount of time the files are stored in GCS.

Is it possible to make a Partitioned table Non-partitioned in BigQuery?
It is possible!! Quick and Free ($0.00)
Step 1 - Create new non-partitioned table with exact same schema as your source table and no rows
#standardSQL
SELECT *
FROM `xxx.yyy.your_partitioned_table`
WHERE FALSE
run above with destination - xxx.yyy.your_new_NON_PARTITIONED_table
Step 2 - Invoke Copy job with WRITE_APPEND as a writeDisposition
Your copy config will look like below
{
"configuration": {
"copy": {
"sourceTable": {
"projectId": "xxx",
"datasetId": "yyy",
"tableId": "your_partitioned_table"
},
"destinationTable": {
"projectId": "xxx",
"datasetId": "yyy",
"tableId": "your_new_NON_PARTITIONED_table"
},
"createDisposition": "CREATE_IF_NEEDED",
"writeDisposition": "WRITE_APPEND"
}
}
}
Mission accomplished!
Note: Both steps are free of charge!
