Table 查询数据库表

public function testBaseUse(): void
{
    $connect = $this->createDatabaseConnectMock();
    $sql = <<<'eot'
        [
            "SELECT `test_query`.* FROM `test_query`",
            [],
            false
        ]
        eot;
    $this->assertSame(
        $sql,
        $this->varJson(
            $connect
                ->table('test_query')
                ->findAll(true)
        )
    );
}

Table 查询指定数据库的表

public function testWithDatabaseName(): void
{
    $connect = $this->createDatabaseConnectMock();
    $sql = <<<'eot'
        [
            "SELECT `test_query`.* FROM `test`.`test_query`",
            [],
            false
        ]
        eot;
    $this->assertSame(
        $sql,
        $this->varJson(
            $connect
                ->table('test.test_query')
                ->findAll(true),
            1
        )
    );
}

Table 查询数据库表，表支持别名

public function testWithAlias(): void
{
    $connect = $this->createDatabaseConnectMock();
    $sql = <<<'eot'
        [
            "SELECT `p`.* FROM `test`.`test_query` `p`",

                ->findAll(true),
            2
        )
    );

    $sql = <<<'eot'
        [
            "SELECT `test_query`.`title`,`test_query`.`body` FROM `test_query`",
            [],

                ->findAll(true)
        )
    );
}

Table 查询数据库表指定字段，字段支持别名

public function testWithFieldAlias(): void

    $sql = <<<'eot'
        [
            "SELECT `test_query`.`title` AS `t`,`test_query`.`name`,`test_query`.`remark`,`test_query`.`value` FROM `test`.`test_query`",

    $subSql = $connect->table('test_query')->makeSql(true);
    $sql = <<<'eot'
        [
            "SELECT `a`.* FROM (SELECT `test_query`.* FROM `test_query`) a",
            [],
            false
        ]
        eot;
    $this->assertSame(
        $sql,
        $this->varJson(
            $connect
                ->table($subSql.' as a')
                ->findAll(true)
        )
    );
}

Table 查询数据库表支持子查询,子查询可以为数据库查询对象

public function testSubIsSelect(): void
{
    $connect = $this->createDatabaseConnectMock();
    $subSql = $connect->table('test_query');
    $sql = <<<'eot'
        [
            "SELECT `bb`.* FROM (SELECT `test_query`.* FROM `test_query`) bb",
            [],
            false
        ]
        eot;
    $this->assertSame(
        $sql,
        $this->varJson(
            $connect
                ->table(['bb' => $subSql])
                ->findAll(true)
        )
    );
}

Table 查询数据库表支持子查询,子查询可以为数据库条件对象

public function testSubIsCondition(): void
{
    $connect = $this->createDatabaseConnectMock();
    $subSql = $connect->table('test_query')->databaseCondition();
    $sql = <<<'eot'
        [
            "SELECT `bb`.* FROM (SELECT `test_query`.* FROM `test_query`) bb",
            [],
            false
        ]
        eot;
    $this->assertSame(
        $sql,
        $this->varJson(
            $connect
                ->table(['bb' => $subSql])
                ->findAll(true)
        )
    );
}

Table 查询数据库表支持子查询,子查询可以为闭包

public function testSubIsClosure(): void
{
    $connect = $this->createDatabaseConnectMock();
    $sql = <<<'eot'
        [
            "SELECT `b`.* FROM (SELECT `test_query`.* FROM `test_query`) b",
            [],
            false
        ]
        eot;
    $this->assertSame(
        $sql,
        $this->varJson(
            $connect
                ->table(['b'=> function ($select) {
                    $select->table('test_query');
                }])
                ->findAll(true)
        )
    );
}

Table 查询数据库表支持子查询,子查询可以为闭包,未指定别名默认为自身

public function testSubIsClosureWithItSeltAsAlias(): void
{
    $connect = $this->createDatabaseConnectMock();
    $sql = <<<'eot'
        [
            "SELECT `guest_book`.* FROM (SELECT `guest_book`.* FROM `guest_book`) guest_book",
            [],
            false
        ]
        eot;
    $this->assertSame(
        $sql,
        $this->varJson(
            $connect
                ->table(function ($select) {
                    $select->table('guest_book');
                })
                ->findAll(true)
        )
    );
}

Table 查询数据库表支持子查询,子查询可以为闭包,还可以进行 join 查询

public function testSubIsClosureWithJoin(): void
{
    $connect = $this->createDatabaseConnectMock();
    $sql = <<<'eot'
        [
            "SELECT `test_query`.`remark`,`test_query_subsql`.`name`,`test_query_subsql`.`value` FROM (SELECT `test_query`.* FROM `test_query`) test_query INNER JOIN `test_query_subsql` ON `test_query_subsql`.`name` = `test_query`.`name`",
            [],
            false
        ]
        eot;
    $this->assertSame(
        $sql,
        $this->varJson(
            $connect
                ->table(function ($select) {
                    $select->table('test_query');
                }, 'remark')
                ->join('test_query_subsql', 'name,value', 'name', '=', Condition::raw('[test_query.name]'))
                ->findAll(true)
        )
    );
}
