查询数据.select

Testing Is Documentation

tests/Database/Read/SelectTest.php

Uses

<?php
use Tests\Database\DatabaseTestCase as TestCase;

select 查询指定 SQL

public function testBaseUse(): void
{
    $connect = $this->createDatabaseConnectMock();
    $sql = <<<'eot'
        [
            "select *from test where id = ?",
            [
                1
            ],
            false
        ]
        eot;
    $this->assertSame(
        $sql,
        $this->varJson(
            $connect
                ->sql()
                ->table('test')
                ->select('select *from test where id = ?', [1])
        )
    );
}

select 直接查询

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

select 查询支持闭包

public function testSelectClosure(): void
{
    $connect = $this->createDatabaseConnectMock();
    $sql = <<<'eot'
        [
            "SELECT `test`.* FROM `test` WHERE `test`.`id` = :test_id",
            {
                "test_id": [
                    1
                ]
            },
            false
        ]
        eot;
    $this->assertSame(
        $sql,
        $this->varJson(
            $connect
                ->sql()
                ->table('test')
                ->select(function ($select) {
                    $select->where('id', 1);
                }),
            2
        )
    );
}

select 查询支持 \Leevel\Database\Select 对象

public function testSelectObject(): void
{
    $connect = $this->createDatabaseConnectMock();
    $sql = <<<'eot'
        [
            "SELECT `test`.* FROM `test` WHERE `test`.`id` = :test_id",
            {
                "test_id": [
                    5
                ]
            },
            false
        ]
        eot;
    $select = $connect
        ->table('test')
        ->where('id', 5);
    $this->assertSame(
        $sql,
        $this->varJson(
            $connect
                ->sql()
                ->select($select),
            3
        )
    );
}
