+# SQL-Helper-Files
+
+PostgreSQL helper files for psql, for include via `\ir helper/....` in SQL files.
+
+This helper files contains mostly command for setting permissions.
+
+## Documentation, Usage
+
+Common usage is to set some psql variables before include; some variables are usually global, others local for each call.
+
+
+### Global variables:
+
+
+```
+--   Name               Value
+-- -------------------------------------------
+\set schema             my_project
+\set db                 my_projectau
+
+\set user_prefix        my_project
+                     
+\set owner              :user_prefix _owner
+\set default_reader     :user_prefix _reader
+\set default_updater    :user_prefix _updater
+\set default_inserter   :user_prefix _inserter
+```
+
+
+### Local variables
+
+Usually you have to set `table` or `function` to the name of the current table or function. Grant scripts include call of revoke scripts!
+
+```
+\set table   last_created_table
+\ir  helper/20-grant-default-reader.sql
+```
