# pdsql

*pdsql* use PowerDNS [generic sql](https://github.com/PowerDNS/pdns/tree/master/pdns/backends/gsql) as backend.

Use [jinzhu/gorm](https://github.com/jinzhu/gorm) to handle database, support many database as gorm dose.

## Syntax

~~~ txt

pdsql   {

    # enable debug mode

    debug [db]

    # create table for test

    auto-migrate

}

~~~

## Install Driver

pdsql need db driver for dialect, to install a driver you need to add import in plugin.cfg, like

~~~ txt

pdsql_mysql:github.com/jinzhu/gorm/dialects/mysql

pdsql_sqlite:github.com/jinzhu/gorm/dialects/sqlite

~~~

pdsql_mysql and pdsql_sqlite are meaningless, choose to prevent duplicated.

## Examples

Start a server on the 1053 port, use test.db as backend.

~~~ corefile

test.:1053 {

    pdsql sqlite3 ./test.db {

        debug db

        auto-migrate

    }

}

~~~

Prepare data for test.

~~~ bash

# Insert records for wener.test

sqlite3 ./test.db 'insert into records(name,type,content,ttl,disabled)values("wener.test","A","192.168.1.1",3600,0)'

sqlite3 ./test.db 'insert into records(name,type,content,ttl,disabled)values("wener.test","TXT","TXT Here",3600,0)'

~~~

When queried for "wener.test. A", CoreDNS will respond with:

~~~ txt

;; QUESTION SECTION:

;wener.test.			IN	A

;; ANSWER SECTION:

wener.test.		3600	IN	A	192.168.1.1

~~~

When queried for "wener.test. ANY", CoreDNS will respond with:

~~~ txt

;; QUESTION SECTION:

;wener.test.			IN	ANY

;; ANSWER SECTION:

wener.test.		3600	IN	A	192.168.1.1

wener.test.		3600	IN	TXT	"TXT Here"

~~~

### Wildcard

~~~ bash

# domain id 1

sqlite3 ./test.db 'insert into domains(name,type)values("example.test","NATIVE")'

sqlite3 ./test.db 'insert into records(domain_id,name,type,content,ttl,disabled)values(1,"*.example.test","A","192.168.1.1",3600,0)'

~~~

When queried for "first.example.test. A", CoreDNS will respond with:

~~~ txt

;; QUESTION SECTION:

;first.example.test.		IN	A

;; ANSWER SECTION:

first.example.test.	3600	IN	A	192.168.1.1

~~~

## TODO

* [x] support wildcard record
