Convenient SQL for monitoring Postgres database health. This repository is inspired by commands from Heroku's pg_extras repository.
You can run a script using
-f option. For example:
$ psql postgres -f sql/cache_hit_rate.sql
It also works with aliases you have setup with
$ alias psql_my_db="psql -h my_db.com -d my_db -U admin" $ psql_my_db -f sql/cache_hit_rate.sql
You can also copy/paste any of the SQL in the
sql/ directory and run with the Postgres client of your choice.
Pull requests for bug fixes, improvements, or new SQL are always welcome!
SQL stands for Structured Query Language. SQL is a scripting language expected to store, control, and inquiry information put away in social databases. The main manifestation of SQL showed up in 1974, when a gathering in IBM built up the principal model of a social database. The primary business social database was discharged by Relational Software later turning out to be Oracle.
Models for SQL exist. In any case, the SQL that can be utilized on every last one of the major RDBMS today is in various flavors. This is because of two reasons:
1. The SQL order standard is genuinely intricate, and it isn’t handy to actualize the whole standard.
2. Every database seller needs an approach to separate its item from others.
Right now, contrasts are noted where fitting.

When working in the SQL Server, we may have to check some other databases other than the current one which we are working. In that scenario we may not be sure that does we have access to those Databases?. In this article we discuss the list of databases that are available for the current logged user in SQL Server

Define: SQL [pron. “sequel”] – stands for Structured Query Language (SQL), used by databases to model and manage tabular/relational datasets; a set of standardized Data Definition Language (DDL) functions to create tables, views, and define relational schema models, and Data Manipulation Language (DML) to query, insert, and modify data in the tables.
*Read-only select queries are technically part of its Data Query Language (DQL) group. Still, operationally, many refer to it as DML because it can do more than read-only queries.
