all_test

SQL

SELECT id,name,tel,zip,SUBSTRING(zip,1,3) AS zip1,SUBSTRING(zip,4,4) AS zip2
FROM all_test
ORDER BY id ASC;

結果

DispatchQueue #1

//0.02秒後に実行
DispatchQueue.main.asyncAfter(deadline: DispatchTime.now() + 0.02) {
    //処理
}

String extension #1

下記2つのテーブルをtelカラムでjoinしたい

all_test

sub_infos

SQL

SELECT a.id,a.name,a.tel,s.id AS sub_id,s.tel AS sub_tel
FROM all_test AS a
LEFT JOIN sub_infos AS s
ON FIND_IN_SET(a.tel,REPLACE(s.tel,'-',''))
ORDER BY id ASC;

結果

Array Extension #2

mutating func switchValue(_ index1:Int,index2:Int){
    let _index1:Int = (index1 < 0) ? self.count + index1 : index1
    let _index2:Int = (index2 < 0) ? self.count + index2 : index2
    let elm = self[_index1]
    self[_index1] = self[_index2]
    self[_index2] = elm
}
