Rebuild all table indexes for database

USE 'database_name' --Enter the name of the database you want to reindex 
 
DECLARE @TableName varchar(255) 
DECLARE TableCursor CURSOR FOR 
SELECT table_name FROM information_schema.tables 
WHERE table_type = 'base table' 

OPEN TableCursor 

FETCH NEXT FROM TableCursor INTO @TableName 
WHILE @@FETCH_STATUS = 0 
BEGIN 
DBCC DBREINDEX('TableName',' ',90) 
FETCH NEXT FROM TableCursor INTO @TableName 
END 
 
CLOSE TableCursor 
DEALLOCATE TableCursor 

Check if table exists before adding or removing it

IF OBJECT_ID('dbo. MyTable_Name', 'U') IS NOT NULL
DROP TABLE MyTable_Name

IF OBJECT_ID('dbo. MyTable_Name', 'U') IS NOT NULL
CREATE TABLE MyTable_Name(
TheDateTime datetime NOT NULL,
Name nvarchar(64) NOT NULL,
Data varbinary(MAX) NOT NULL)
