+
+`bq query --nouse_legacy_sql 'SELECT COUNT(*) FROM {{DATASET_NAME}}.{{TABLE_NAME}}'`
+
+- Run a parameterized query:
+
+`bq query --use_legacy_sql=false --parameter='ts_value:TIMESTAMP:2016-12-07 08:00:00' 'SELECT TIMESTAMP_ADD(@ts_value, INTERVAL 1 HOUR)'`
+

+
+`bq mk --location=US {{dataset_name}}.{{table_name}}`
+
+- List all datasets in a project:
+
+`bq ls --filter labels.{{key}}:{{value}} --max_results {{integer}} --format=prettyjson --project_id {{project_id}}`
+
+- Batch load data from a specific file in formats such as CSV, JSON, Parquet, and Avro to a table:
+
+`bq load --location={{location}} --source_format={{CSV|JSON|PARQUET|AVRO}} {{dataset}}.{{table}} {{path_to_source}}`
