|
||||
|
||||
<h2>Overview</h2>
|
||||
|
||||
<p>The DB module is a unified interface to database access.
|
||||
Database dialects is supported by custom database driver shards.
|
||||
Check <a href="https://github.com/manastech/crystal-sqlite3" target="_blank">manastech/crystal-sqlite3</a> for example.</p>
|
||||
|
||||
<p>Drivers implementors check <code><a href="DB/Driver.html">Driver</a></code> class.</p>
|
||||
|
||||
<p>DB manage a connection pool. The connection pool can be configured by <code>URI</code> query. See <code><a href="DB/Database.html">Database</a></code>.</p>
|
||||
|
||||
<h3>Usage</h3>
|
||||
|
||||
<p>Assuming <code>crystal-sqlite3</code> is included a sqlite3 database can be opened with <code><a href="DB.html#open%28uri%3AURI%7CString%29-class-method">#open</a></code>.</p>
|
||||
|
||||
<pre><code>db <span class="o">=</span> <span class="t">DB</span>.open <span class="s">"sqlite3:./path/to/db/file.db"</span>
|
||||
db.close</code></pre>
|
||||
|
||||
<p>If a block is given to <code><a href="DB.html#open%28uri%3AURI%7CString%29-class-method">#open</a></code> the database is closed automatically</p>
|
||||
|
||||
<pre><code><span class="t">DB</span>.open <span class="s">"sqlite3:./file.db"</span> <span class="k">do</span> <span class="o">|</span>db<span class="o">|</span>
|
||||
<span class="c"># work with db</span>
|
||||
<span class="k">end</span> <span class="c"># db is closed</span></code></pre>
|
||||
|
||||
<p>In the code above <code>db</code> is a <code><a href="DB/Database.html">Database</a></code>. Methods available for querying it are described in <code><a href="DB/QueryMethods.html">QueryMethods</a></code>.</p>
|
||||
|
||||
<p>Three kind of statements can be performed:</p>
|
||||
|
||||
<ol><li><code>Database#exec</code> waits no response from the database.</li><li><code>Database#scalar</code> reads a single value of the response.</li><li><code>Database#query</code> returns a ResultSet that allows iteration over the rows in the response and column information.</li></ol>
|
||||
|
||||
<p>All of the above methods allows parametrised query. Either positional or named arguments.</p>
|
||||

||||

|

</div>
|
||||
|
||||
<div class="doc"><p>The <code><a href="DB.html#mapping-macro">DB.mapping</a></code> macro defines how an object is built from a DB::ResultSet.</p>
|
||||
|
||||
<p>It takes hash literal as argument, in which attributes and types are defined.
|
||||
Once defined, <code><a href="DB/ResultSet.html#read%28type%3ADB%3A%3AMappable.class%29-instance-method">DB::ResultSet#read(t)</a></code> populates properties of the class from the
|
||||
result set.</p>
|
||||
|
||||
<pre><code class='language-crystal'><span class="k">require</span> <span class="s">"db"</span>
|
||||
|
||||
<span class="k">class</span> <span class="t">Employee</span>
|
||||
<span class="t">DB</span>.mapping({
|
||||
title: <span class="t">String</span>,
|
||||
name: <span class="t">String</span>,
|
||||
})
|
||||
<span class="k">end</span>
|
||||
|
||||
employees <span class="o">=</span> <span class="t">Employee</span>.from_rs(db.query(<span class="s">"SELECT title, name FROM employees"</span>))
|
||||
employees[<span class="n">0</span>].title <span class="c"># => "Manager"</span>
|
||||
employees[<span class="n">0</span>].name <span class="c"># => "John"</span></code></pre>
|
||||
|
||||
<p>Attributes not mapped with <code><a href="DB.html#mapping-macro">DB.mapping</a></code> are not defined as properties.
|
||||
Also, missing attributes raise a <code>DB::Exception</code>.</p>
|
||||
|
||||
<p>You can also define attributes for each property.</p>
|
||||
|
||||
<pre><code class='language-crystal'><span class="k">class</span> <span class="t">Employee</span>
|
||||
<span class="t">DB</span>.mapping({
|
||||
title: <span class="t">String</span>,
|
||||
name: {
|
||||
<span class="k">type</span>: <span class="t">String</span>,
|
||||
nilable: <span class="n">true</span>,
|
||||
key: <span class="s">"firstname"</span>,
|
||||
},
|
||||
})
|
||||
<span class="k">end</span></code></pre>
|
||||
|
||||
<p>Available attributes:</p>
|
||||
|
||||
<ul><li><em>type</em> (required) defines its type. In the example above, <em>title: String</em> is a shortcut to <em>title: {type: String}</em>.</li><li><em>nilable</em> defines if a property can be a <code>Nil</code>.</li><li><strong>default</strong>: value to use if the property is missing in the result set, or if it's <code>null</code> and <code>nilable</code> was not set to <code>true</code>. If the default value creates a new instance of an object (for example <code>[1, 2, 3]</code> or <code>SomeObject.new</code>), a different instance will be used each time a row is parsed.</li><li><em>key</em> defines which column to read from a reusltset. It defaults to the name of the property.</li><li><em>converter</em> takes an alternate type for parsing. It requires a <code>#from_rs</code> method in that class, and returns an instance of the given type.</li></ul>
|
||||
|
||||
<p>The mapping also automatically defines Crystal properties (getters and setters) for each
|
||||
of the keys. It doesn't define a constructor accepting those arguments, but you can provide
|
||||
an overload.</p>
|
||||
|
||||
<p>The macro basically defines a constructor accepting a <code><a href="DB/ResultSet.html">DB::ResultSet</a></code> that reads from
|
||||
it and initializes this type's instance variables.</p>
|
||||
|
||||
<p>This macro also declares instance variables of the types given in the mapping.</p></div>

<h2>Overview</h2>
|
||||
|
||||
<p>Database driver implementors must subclass <code><a href="../DB/Connection.html">Connection</a></code>.</p>
|
||||
|
||||
<p>Represents one active connection to a database.</p>
|
||||
|
||||
<p>Users should never instantiate a <code><a href="../DB/Connection.html">Connection</a></code> manually. Use <code><a href="../DB.html#open%28uri%3AURI%7CString%29-class-method">DB#open</a></code> or <code>Database#connection</code>.</p>
|
||||
|
||||
<p>Refer to <code><a href="../DB/QueryMethods.html">QueryMethods</a></code> for documentation about querying the database through this connection.</p>
|
||||
|
||||
<h3>Note to implementors</h3>
|
||||
|
||||
<p>The connection must be initialized in <code>#initialize</code> and closed in <code>#do_close</code>.</p>
|
||||
|
||||
<p>Override <code><a href="../DB/Connection.html#build_statement%28query%29%3AStatement-instance-method">#build_statement</a></code> method in order to return a prepared <code><a href="../DB/Statement.html">Statement</a></code> to allow querying.
|
||||
See also <code><a href="../DB/Statement.html">Statement</a></code> to define how the statements are executed.</p>
|
||||
|
||||
<p>If at any give moment the connection is lost a DB::ConnectionLost should be raised. This will
|
||||
allow the connection pool to try to reconnect or use another connection if available.</p>

<h2>Overview</h2>
|
||||
|
||||
<p>Acts as an entry point for database access.
|
||||
Connections are managed by a pool.
|
||||
The connection pool can be configured from URI parameters:</p>
|
||||
|
||||
<ul><li>initial_pool_size (default 1)</li><li>max_pool_size (default 0 = unlimited)</li><li>max_idle_pool_size (default 1)</li><li>checkout_timeout (default 5.0)</li><li>retry_attempts (default 1)</li><li>retry_delay (in seconds, default 1.0)</li></ul></ul>
|
||||
|
||||
<p>It should be created from DB module. See <code><a href="../DB.html#open%28uri%3AURI%7CString%29-class-method">DB#open</a></code>.</p>
|
||||
|
||||
<p>Refer to <code><a href="../DB/QueryMethods.html">QueryMethods</a></code> for documentation about querying the database.</p>

<h2>Overview</h2>
|
||||
|
||||
<p>When a statement is to be executed in a DB that has a connection pool
|
||||
a statement from the DB needs to be able to represent a statement in any
|
||||
of the connections of the pool. Otherwise the user will need to deal with
|
||||
actual connections in some point.</p>

<h2>Overview</h2>
|
||||
|
||||
<p>Methods to allow querying a database.
|
||||
All methods accepts a <code>query : String</code> and a set arguments.</p>
|
||||
|
||||
<p>Three kind of statements can be performed:</p>
|
||||
|
||||
<ol><li><code><a href="../DB/QueryMethods.html#exec%28query%2C%2Aargs%29-instance-method">#exec</a></code> waits no record response from the database. An <code><a href="../DB/ExecResult.html">ExecResult</a></code> is returned.</li><li><code><a href="../DB/QueryMethods.html#scalar%28query%2C%2Aargs%29-instance-method">#scalar</a></code> reads a single value of the response. A union of possible values is returned.</li><li><code><a href="../DB/QueryMethods.html#query%28query%2C%2Aargs%29-instance-method">#query</a></code> returns a <code><a href="../DB/ResultSet.html">ResultSet</a></code> that allows iteration over the rows in the response and column information.</li></ol>
|
||||
|
||||
<p>Arguments can be passed by position</p>
|
||||
|
||||
<pre><code>db.query(<span class="s">"SELECT name FROM ... WHERE age > ?"</span>, age)</code></pre>
|
||||
|
||||
<p>Convention of mapping how arguments are mapped to the query depends on each driver.</p>
|
||||
|
||||
<p>Including <code><a href="../DB/QueryMethods.html">QueryMethods</a></code> requires a <code>prepare(query) : <a href="../DB/Statement.html">Statement</a></code> method that is not expected
|
||||
to be called directly.</p>
|
||||

<h2>Overview</h2>
|
||||
|
||||
<p>The response of a query performed on a <code><a href="../DB/Database.html">Database</a></code>.</p>
|
||||
|
||||
<p>See <code><a href="../DB.html">DB</a></code> for a complete sample.</p>
|
||||
|
||||
<p>Each <code><a href="../DB/ResultSet.html#read-instance-method">#read</a></code> call consumes the result and moves to the next column.
|
||||
Each column must be read in order.
|
||||
At any moment a <code><a href="../DB/ResultSet.html#move_next%3ABool-instance-method">#move_next</a></code> can be invoked, meaning to skip the
|
||||
remaining, or even all the columns, in the current row.
|
||||
Also it is not mandatory to consume the whole <code><a href="../DB/ResultSet.html">ResultSet</a></code>, hence an iteration
|
||||
through <code><a href="../DB/ResultSet.html#each%28%26block%29-instance-method">#each</a></code> or <code><a href="../DB/ResultSet.html#move_next%3ABool-instance-method">#move_next</a></code> can be stopped.</p>
|
||||
|
||||
<p><strong>Note:</strong> depending on how the <code><a href="../DB/ResultSet.html">ResultSet</a></code> was obtained it might be mandatory an
|
||||
explicit call to <code>#close</code>. Check <code><a href="../DB/QueryMethods.html#query%28query%2C%2Aargs%29-instance-method">QueryMethods#query</a></code>.</p>
|
||||
|
||||
<h3>Note to implementors</h3>

||||

||||
<ol><li>Override <code><a href="../DB/ResultSet.html#move_next%3ABool-instance-method">#move_next</a></code> to move to the next row.</li><li>Override <code><a href="../DB/ResultSet.html#read-instance-method">#read</a></code> returning the next value in the row.</li><li>(Optional) Override <code><a href="../DB/ResultSet.html#read%28type%3ADB%3A%3AMappable.class%29-instance-method">#read(t)</a></code> for some types <code>t</code> for which custom logic other than a simple cast is needed.</li><li>Override <code><a href="../DB/ResultSet.html#column_count%3AInt32-instance-method">#column_count</a></code>, <code><a href="../DB/ResultSet.html#column_name%28index%3AInt32%29%3AString-instance-method">#column_name</a></code>.</li></ol>

<h1>crystal-db</h1>
|
||||
|
||||
<p>Common db api for crystal. You will need to a specific driver to access a database.</p>
|
||||
|
||||
<ul><li><a href="https://github.com/crystal-lang/crystal-sqlite3" target="_blank">sqlite</a></li><li><a href="https://github.com/crystal-lang/crystal-mysql" target="_blank">mysql</a></li></ul>
|
||||
|
||||
<h2>Installation</h2>
|
||||
|
||||
<p>Add this to your application's <code>shard.yml</code>:</p>
|
||||
|
||||
<pre><code class='language-yaml'>dependencies:
|
||||
db:
|
||||
github: crystal-lang/crystal-db</code></pre>
|
||||
|
||||
<h2>Usage</h2>
|
||||
|
||||
<p>Since this is an abstract db api, it's usage is through a concrete database driver.</p>
