• aws_athena_cloudtrail_ddl.sql - AWS Athena DDL to setup up integration to query CloudTrail logs from Athena
• bigquery_*.sql - Google BigQuery scripts:
  • bigquery_billing_*.sql - billing queries for GCP usage eg. highest cost services, most used GCP products, recent charges etc.
  • bigquery_info_*.sql - information schema queries for datasets, tables, columns, partitioning, clustering etc.
• mysql_*.sql:
  • MySQL / MariaDB queries for DBA investigating + performance tuning
  • mysql_info.sql - summary overview, useful to debug your mysql.user table auth effects
    • (shows intended USER() vs actual CURRENT_USER())
  • tested on MySQL 5.5, 5.6, 5.7, 8.0 and MariaDB 5.5, 10.x
• postgres_*.sql:
  • PostgreSQL queries for DBA investigating + performance tuning
  • postgres_info.sql - big summary overview, recommend you start here
  • tested on PostgreSQL 8.4, 9.x, 10.x, 11.x, 12.x, 13.x

• bigquery_*.sql - Google BigQuery scripts:
  • bigquery_billing_*.sql - billing queries for GCP usage eg. highest cost services, most used GCP products, recent charges etc.
  • bigquery_info_*.sql - information schema queries for datasets, tables, columns, partitioning, clustering etc.
  • analytics/bigquery_*.sql - ecommerce queries and BigQuery ML machine learning classification logistic regression models and purchasing predictions
  • for more BigQuery examples, see Data Engineering demos

You can quickly test the PostgreSQL / MySQL scripts using postgres.sh / mysqld.sh / mariadb.sh in the DevOps Bash tools repo, which boots a docker container and drops straight in to a mysql / psql shell with this directory mounted at /sql and used as $PWD for fast easy sourcing eg.

postgres:

\i /sql/postgres_query_times.sql 

mysql:

source /sql/mysql_sessions.sql 

or just

\i postgres_query_times.sql 

\. mysql_sessions.sql 

since the $PWD is set to /sql for convenience.

• .psqlrc - advanced PostgreSQL psql client config
• psql.sh - quickly connect to PostgreSQL with command line switches inferred from environment variables
• mysql.sh - quickly connect to MySQL / MariaDB with command line switches inferred from environment variables
• postgres.sh - one-touch PostgreSQL, boots docker container and drops you in to psql shell. Version can be given as an argument
• mysqld.sh / mariadb.sh - one-touch MySQL / MariaDB, boots docker container and drops you in to mysql shell. Version can be given as an argument
• postgres_foreach_table.sh / mysql_foreach_table.sh - execute templated SQL queries/statements against all or a subset of tables
• postgres_tables_row_counts.sh / mysql_tables_row_counts.sh - get row counts for all or a subset of tables
• sqlcase.pl - autocases your SQL code
  • I use this a lot and call it via hotkey configured in my .vimrc
  • there are *case.pl specializations for most of the major RDBMS and distributed SQL systems, even several NoSQL systems, using each one's language specific keywords
• Hive & Impala SQL:
  • beeline.sh - quickly connect to Hive, auto-determines HiveServer2 address, Kerberos & SSL options, ZooKeeper quorum
  • impala_shell.sh - quickly connect to Impala, auto-determines a Hadoop worker node address and Kerberos options (can use an environment variable for a Load Balancer setup)
  • hive_foreach_table.sh / impala_foreach_table.sh - execute templated SQL queries/statements against all or a subset of tables
  • hive_tables_row_counts.sh / impala_tables_row_counts.sh - get row counts for all or a subset of tables
  • hive_tables_column_counts.sh / impala_tables_column_counts.sh - get the column counts for big tables in Hive / Impala
  • hive_tables_metadata.sh / impala_tables_metadata.sh / hive_tables_locations.sh / impala_tables_locations.sh - get Hive / Impala metadata for all or a subset of tables, eg. Location to determine where the external tables data is being stored (HDFS / S3 paths)
