MySqlは、既存のテーブルのカラムと別のテーブルの別のルックアップを使用して新しいテーブルを作成します。

Question

データベースに2つのテーブル、つまりTable_1とTable_2があります。

Combined_tableという新しいテーブルに、Table_1とTable_2の情報を組み合わせる必要があります。

Table_1カラムの名前と値は、Combined_tableに直接コピーできます。

名前がService Descriptionの別の値からなる列を追加する必要があります。これはTable_2です。それぞれ異なる値は、Combined_tableに追加された列名になります。

これらの新しい追加列は、それぞれの値を正しい行に追加する必要があります。各行は、すべての表で利用可能なMSISDN列を介して識別できます。 Combined_tableがどのように見えるべきかの

Table_1

PHPを使用してテーブルを作成する方法はわかりません。 私はデータを作成して追加するための単一のMySQLリクエストを実行することを考えましたが、開始方法はわかりません。

アドバイスは非常に役に立ちます。あなたは列名（つまり、明確な説明を）知っている場合は、すでに、あなたは、テーブルを作成し、このようなSELECTクエリを書くことができます

Answer 1

：

SELECT MSISDN, Abar Date, Upgrd, Pack Code, Tariff, Avg Spend, SIM Number, 
(SELECT COALESCE(SUM(VALUE), 0) FROM Table_2 WHERE MSISDN = t1.MSISDN AND description = '100MB') AS 100MB, 
(SELECT COALESCE(SUM(VALUE), 0) FROM Table_2 WHERE MSISDN = t1.MSISDN AND description = 'Basic Data 9600') AS 'Basic Data 9600', 
(SELECT COALESCE(SUM(VALUE), 0) FROM Table_2 WHERE MSISDN = t1.MSISDN AND description = 'Basic Telephony') AS 'Basic Telephony', 
(SELECT COALESCE(SUM(VALUE), 0) FROM Table_2 WHERE MSISDN = t1.MSISDN AND description = 'Ebilling - Corporate CD Extract') AS 'Ebilling - Corporate CD Extract', 
(SELECT COALESCE(SUM(VALUE), 0) FROM Table_2 WHERE MSISDN = t1.MSISDN AND description = 'Unrestricted APN') AS 'Unrestricted APN' 
FROM Table_1 t1; 

あなたはこれらの列を持つテーブルを作成し、INSERT INTOを使用することができます。 SELECT構文

INSERT INTO table_3 
SELECT MSISDN, Abar Date, Upgrd, Pack Code, Tariff, Avg Spend, SIM Number, 
(SELECT COALESCE(SUM(VALUE), 0) FROM Table_2 WHERE MSISDN = t1.MSISDN AND description = '100MB') AS 100MB, 
(SELECT COALESCE(SUM(VALUE), 0) FROM Table_2 WHERE MSISDN = t1.MSISDN AND description = 'Basic Data 9600') AS 'Basic Data 9600', 
(SELECT COALESCE(SUM(VALUE), 0) FROM Table_2 WHERE MSISDN = t1.MSISDN AND description = 'Basic Telephony') AS 'Basic Telephony', 
(SELECT COALESCE(SUM(VALUE), 0) FROM Table_2 WHERE MSISDN = t1.MSISDN AND description = 'Ebilling - Corporate CD Extract') AS 'Ebilling - Corporate CD Extract', 
(SELECT COALESCE(SUM(VALUE), 0) FROM Table_2 WHERE MSISDN = t1.MSISDN AND description = 'Unrestricted APN') AS 'Unrestricted APN' 
FROM Table_1 t1; 

Answer 2

は、私は、ライブデータベーステーブルからあなたsugestionsといくつかの実際のデータを使用して、以下をコンパイルするために管理

ダルシャン

ありがとうございます。

が正常に動作し、一時テーブルを作成します。

CREATE table `infolog_SIMS` (`MSISDN` VARCHAR(50), `Abar Date` VARCHAR(50), `Term Date` VARCHAR(50), `Upgrd` VARCHAR(50), `Upgrd date` VARCHAR(50), `Pack Code` VARCHAR(50), `Tariff` VARCHAR(50), `Pack Desc` VARCHAR(50), `Avg Spend` VARCHAR(50), `Stat` VARCHAR(50), `SIM Number` VARCHAR(50)); 

その後一時テーブルを余分な列を追加し、また、正常に動作します::

今

ALTER TABLE `infolog_SIMS` ADD COLUMN `100MB` VARCHAR(50) NOT NULL, ADD COLUMN `Basic Data 9600` VARCHAR(50) NOT NULL, ADD COLUMN `Basic Telephony` VARCHAR(50) NOT NULL, ADD COLUMN `Ebilling Corporate CD Extract` VARCHAR(50) NOT NULL, ADD COLUMN `LTE` VARCHAR(50) NOT NULL, ADD COLUMN `MMS Standard` VARCHAR(50) NOT NULL, ADD COLUMN `Unrestricted APN` VARCHAR(50) NOT NULL, ADD COLUMN `My Meg 0` VARCHAR(50) NOT NULL, ADD COLUMN `SMS Mobile Originating` VARCHAR(50) NOT NULL, ADD COLUMN `Caller Identity FREE` VARCHAR(50) NOT NULL, ADD COLUMN `Promotional My Gig 1 24 Months` VARCHAR(50) NOT NULL, ADD COLUMN `MyMeg 30 Mobile Internet Bundle` VARCHAR(50) NOT NULL, ADD COLUMN `15MB` VARCHAR(50) NOT NULL, ADD COLUMN `SPNwww.infolog.co.za` VARCHAR(50) NOT NULL, ADD COLUMN `Make Nat. Int. Roam Calls` VARCHAR(50) NOT NULL, ADD COLUMN `Outgoing Bar` VARCHAR(50) NOT NULL; 

値を持つそれぞれの行のために追加します：

SELECT *, (SELECT `Value` FROM `Infolog_temp_VAS` WHERE `Dialling No` = `t1`.`MSISDN` AND `Service Description` = '100MB') AS '100MB', (SELECT `Value` FROM `Infolog_temp_VAS` WHERE `Dialling No` = `t1`.`MSISDN` AND `Service Description` = 'Basic Data 9600') AS 'Basic Data 9600', (SELECT `Value` FROM `Infolog_temp_VAS` WHERE `Dialling No` = `t1`.`MSISDN` AND `Service Description` = 'Basic Telephony') AS 'Basic Telephony', (SELECT `Value` FROM `Infolog_temp_VAS` WHERE `Dialling No` = `t1`.`MSISDN` AND `Service Description` = 'Ebilling Corporate CD Extract') AS 'Ebilling Corporate CD Extract', (SELECT `Value` FROM `Infolog_temp_VAS` WHERE `Dialling No` = `t1`.`MSISDN` AND `Service Description` = 'LTE') AS 'LTE', (SELECT `Value` FROM `Infolog_temp_VAS` WHERE `Dialling No` = `t1`.`MSISDN` AND `Service Description` = 'MMS Standard') AS 'MMS Standard', (SELECT `Value` FROM `Infolog_temp_VAS` WHERE `Dialling No` = `t1`.`MSISDN` AND `Service Description` = 'Unrestricted APN') AS 'Unrestricted APN', (SELECT `Value` FROM `Infolog_temp_VAS` WHERE `Dialling No` = `t1`.`MSISDN` AND `Service Description` = 'My Meg 0') AS 'My Meg 0', (SELECT `Value` FROM `Infolog_temp_VAS` WHERE `Dialling No` = `t1`.`MSISDN` AND `Service Description` = 'SMS Mobile Originating') AS 'SMS Mobile Originating', (SELECT `Value` FROM `Infolog_temp_VAS` WHERE `Dialling No` = `t1`.`MSISDN` AND `Service Description` = 'Caller Identity FREE') AS 'Caller Identity FREE', (SELECT `Value` FROM `Infolog_temp_VAS` WHERE `Dialling No` = `t1`.`MSISDN` AND `Service Description` = 'Promotional My Gig 1 24 Months') AS 'Promotional My Gig 1 24 Months', (SELECT `Value` FROM `Infolog_temp_VAS` WHERE `Dialling No` = `t1`.`MSISDN` AND `Service Description` = 'MyMeg 30 Mobile Internet Bundle') AS 'MyMeg 30 Mobile Internet Bundle', (SELECT `Value` FROM `Infolog_temp_VAS` WHERE `Dialling No` = `t1`.`MSISDN` AND `Service Description` = '15MB') AS '15MB', (SELECT `Value` FROM `Infolog_temp_VAS` WHERE `Dialling No` = `t1`.`MSISDN` AND `Service Description` = 'SPNwww.infolog.co.za') AS 'SPNwww.infolog.co.za', (SELECT `Value` FROM `Infolog_temp_VAS` WHERE `Dialling No` = `t1`.`MSISDN` AND `Service Description` = 'Make Nat. Int. Roam Calls') AS 'Make Nat. Int. Roam Calls', (SELECT `Value` FROM `Infolog_temp_VAS` WHERE `Dialling No` = `t1`.`MSISDN` AND `Service Description` = 'Outgoing Bar') AS 'Outgoing Bar' FROM `Infolog_temp_SDR` `t1`; 

の場合Valueフィールドの一部がNULLを返します。エラーテーブルはInfolog_temp_VASテーブルに存在しません。 NULLをNOに変更するためにserviceが存在しない場合は、IF条件を追加することは可能ですか？

これは実際の挿入コマンドではなく、選択部分のみです。
