SQL Server Abfrage mit Joins

Question

Ich habe 4 Tabellen in meiner Datenbank. Ich möchte eine einzelne Abfrage schreiben, die Tabellennamen zurückgibt, nein. Zeilen, Tabellengröße, Datum Tabelle wurde erstellt und geändert, wer war die Tabelle erstellt von.

Meine Datenbank:

CREATE TABLE Branch(
     Br_ID int IDENTITY(1,1) PRIMARY KEY, 
     Name varchar(255), 
     Desp varchar(255) 
); 

CREATE TABLE Region(
     R_ID int IDENTITY(1,1) PRIMARY KEY, 
     Name varchar(255), 
     Desp varchar(255) 
); 

CREATE TABLE Customer(
     Cust_ID int IDENTITY(1,1) PRIMARY KEY, 
     Name varchar(255), 
     Desp varchar(255) 
); 

CREATE TABLE Customer_Branch(
     Br_ID int FOREIGN KEY REFERENCES Branch(Br_ID) not null, 
     Cust_ID int FOREIGN KEY REFERENCES Customer(Cust_ID) not null, 
     PRIMARY KEY (Br_ID, Cust_ID) 
); 

INSERT INTO Branch (Name, Desp) 
VALUES ('xyz', 'headoffice');

Diese Abfrage wird Sollte die Arbeit mit SQL Server 2005 und höher arbeiten.

Sie können diese Abfrage ausführen und die Ausgabe überprüfen, die Sie entsprechend Ihren Anforderungen ändern können.

SELECT 
    t.NAME AS TableName, 
    i.name as indexName, 
    p.[Rows], 
    sum(a.total_pages) as TotalPages, 
    sum(a.used_pages) as UsedPages, 
    sum(a.data_pages) as DataPages, 
    (sum(a.total_pages) * 8)/1024 as TotalSpaceMB, 
    (sum(a.used_pages) * 8)/1024 as UsedSpaceMB, 
    (sum(a.data_pages) * 8)/1024 as DataSpaceMB 
FROM 
    sys.tables t 
INNER JOIN  
    sys.indexes i ON t.OBJECT_ID = i.object_id 
INNER JOIN 
    sys.partitions p ON i.object_id = p.OBJECT_ID AND i.index_id = p.index_id 
INNER JOIN 
    sys.allocation_units a ON p.partition_id = a.container_id 
WHERE 
    t.NAME NOT LIKE 'dt%' AND 
    i.OBJECT_ID > 255 AND 
    i.index_id <= 1 
GROUP BY 
    t.NAME, i.object_id, i.index_id, i.name, p.[Rows] 
ORDER BY 
    object_name(i.object_id) 

Ausgang:

SELECT 
    t.NAME AS TableName, 
    p.rows AS RowCounts, 
    SUM(a.total_pages) * 8 AS TotalSpaceKB, 
    CAST(ROUND(((SUM(a.total_pages) * 8)/1024.00), 2) AS NUMERIC(36, 2)) AS TotalSpaceMB, 
    SUM(a.used_pages) * 8 AS UsedSpaceKB, 
    CAST(ROUND(((SUM(a.used_pages) * 8)/1024.00), 2) AS NUMERIC(36, 2)) AS UsedSpaceMB, 
    (SUM(a.total_pages) - SUM(a.used_pages)) * 8 AS UnusedSpaceKB, 
    CAST(ROUND(((SUM(a.total_pages) - SUM(a.used_pages)) * 8)/1024.00, 2) AS NUMERIC(36, 2)) AS UnusedSpaceMB, 
    t.create_date AS [CreatedDate], 
    t.modify_date AS [ModifiedDate] 
FROM 
    sys.tables t 
INNER JOIN  
    sys.indexes i ON t.OBJECT_ID = i.object_id 
INNER JOIN 
    sys.partitions p ON i.object_id = p.OBJECT_ID AND i.index_id = p.index_id 
INNER JOIN 
    sys.allocation_units a ON p.partition_id = a.container_id 
LEFT OUTER JOIN 
    sys.schemas s ON t.schema_id = s.schema_id 
WHERE 
    t.NAME NOT LIKE 'dt%' 
    AND t.is_ms_shipped = 0 
    AND i.OBJECT_ID > 255 
GROUP BY 
    t.Name, s.Name, p.Rows,t.create_date,t.modify_date 
ORDER BY 
    t.Name 

Result for given query.
