+# QueryBuilder
+
+## Requirements
++ PHP 8+ (Should work with 7+, but haven't tested it).
++ `Psr\Container\ContainerInterface` implementation like [`php-di/php-di`](https://packagist.org/packages/php-di/php-di).
+
+## Installation
+
+```composer.json```
+```
+{
+    ...
+    "repositories": [
+        {
+            "type": "git",
+            "path": "https://git.provm.cl/ProVM/query_builder.git"
+        }
+    ],
+    "require": {
+        ...
+        "provm/query_builder": "^1.0",
+        ...
+    },
+    ...
+}
+```
+
+## Setup
+
+```
+$container->set(ProVM\Concept\Database\Query\Select::class, function(Psr\Container\ContainerInterface $container) {
+    return $container->get(ProVM\Database\Query\MySQL\Select::class);
+});
+$container->set(ProVM\Concept\Database\Query\Insert::class, function(Psr\Container\ContainerInterface $container) {
+    return $container->get(ProVM\Database\Query\MySQL\Insert::class);
+});
+$container->set(ProVM\Concept\Database\Query\Update::class, function(Psr\Container\ContainerInterface $container) {
+    return $container->get(ProVM\Database\Query\MySQL\Update::class);
+});
+$container->set(ProVM\Concept\Database\Query\Delete::class, function(Psr\Container\ContainerInterface $container) {
+    return $container->get(ProVM\Database\Query\MySQL\Delete::class);
+});
+```
+
+## Usage
+
+QueryBuilder
+```
+include_once 'vendor/autoload.php';
+$qb = new QueryBuilder();
+
+$query = $qb->select(<*columns>);
+$query = $qb->insert(<table>);
+$query = $qb->update(<table>);
+$query = $qb->delete(<table>);
+```
+
+### Queries
+
+#### Select
+`SELECT <columns> FROM <table>[ JOIN <table2> ON <table>.<column_1> = <table2>.<column_2>][ WHERE <expr1>[ AND|OR <expr2>]][ GROUP BY <column1>[, <column2>]][ HAVING <expr1>[ AND|OR <expr2>]][ ORDER BY <column1> ASC|DESC[, <column2> ASC|DESC]]`
+
+Mysql also include `[ LIMIT <limit>[ OFFSET <offset>]]`
+```
+$query = $qb->select(); // use '*' for columns
+or
+$query = $qb->select()->select(['id', 'column1',]);
+or
+$query = $qb->select(['id', 'column1',]);
+
+$query->from('table1');
+$query->joins([['table2', 'table1.column1 = table2.column21'],]);
+$query->where(['table2.column22 = 10',]);
+$query->groupBy(['table1.column1',]);
+$query->having(['table1.column1 < 10',]);
+$query->orderBy(['table2.column22',]);
+$query->limit(10, 10);
+```
+
+#### Insert
+`INSERT INTO <table>[ (<columns>)]`
+with two options
+`<select query>` or
+` VALUES (<values>)`
+```
+$query = $qb->insert('table');
+
+$query->columns(['column1',]);
+$query->values(['value1',];
+or
+$query->select($select_query);
+```
+
+#### Update
+`UPDATE <table> SET <column1> = <value1>[, <column2> = <value2>][ WHERE <expr1>[ AND|OR <expr2>]]`
+```
+$query = $qb->update('table');
+$query->set([['column1', 10],]); or $query->set([['column' => 'column1', 'value' => 10],]);
+$query->where(['column2 = 10', ]);
+```
+
+#### Delete
+`DELETE FROM <table> WHERE <expr1>[ AND|OR <expr2>]`
+```
+$query = $qb->delete('table');
+$query->where(['column1 = 10',]);
+```
+
+
+Pass the query to a string
+```
+$str = $query->build();
+or
+$str = "{$query}";
+```
