SSIS Assignment 4: CSV to SQL #Hadling Null #Duplicate Records #Archive #File System Task #For Each Loop #Aggregate Transformation
(In Case Assignment database is not created): Create Database Assignment;
Use Assignment;
Create Table [Operation_Survey]
(
survey_id int primary key,
descr varchar(255),
industry varchar(50),
level int,
size varchar(50),
line_code varchar(50),
value int
);
create Table [Audit]
(
id int identity(1,1),
execution_id varchar(50) not null,
package_name varchar(100) not null,
start_time datetime not null,
end_time datetime not null,
src_count int ,
dest_count int ,
status varchar(20) not null
);
CREATE TABLE [Operation_bad_data](
[survey_id] [varchar](50) NULL,
[descr] [varchar](255) NULL,
[industry] [varchar](50) NULL,
[level] [varchar](50) NULL,
[size] [varchar](50) NULL,
[line_code] [varchar](50) NULL,
[value] [varchar](50) NULL
);
Task 1: Load data (Unique records) from CSV to SQL Server Table [Operation_Survey], with primary key constraint.
Load Null and Duplicate records in another table [Operation_bad_data] for further analysis of that data.
Task 2: Try the above logic with multiple sources (Flat file Files with same metadata), using For Each Loop.
Task 3: Archieving the flat files, once data is loaded to the tables.
Task 4: Use a sequence container and drag ur tasks so created in Task 1 to Task 3, and do manual auditing checking the status of the task.
Hint: Use [Audit] as a auditing table. Create Variables execution_id int, src_count int, dest_count int, execution_end_date datetime (expression: getdate()),execution_strt_date datetime (expression: getdate())
Use 'select Coalesce(max(execution_id)+1,1) from dbo.audit' to load (max id + 1) from audit table in execute SQL Task and place it above sequence container and ouput as single row and map variable (execution_id 0)
Drag one more Execute SQL Task, after first excecute sql task above sequence container and go to expressions:sql satatemet source
"Insert into dbo.[Audit] (execution_id, package_name, start_time, end_time, src_count, dest_count, status)
values ("+ (DT_WSTR, 5) @[User::Execution_Id]+","+@[System::PackageName]+" , CAST('"+(DT_WSTR, 30) @[User::execution_strt_date] +"' AS DATETIME) ,'','','', 'Started')"
Drag two execute sql task at the end of sequence container - one with precendence constraint (line connecting sequence container and task) as success and another one for failure.
For success: "UPDATE dbo.Audit
SET end_time = CAST('"+(DT_WSTR, 30) @[User::execution_end_date] +"' AS DATETIME),src_count = "+ (DT_WSTR, 10) @[User::src_count] +",
dest_count = "+ (DT_WSTR, 10) @[User::dest_count] +",status = 'Completed'
where execution_id ="+ (DT_WSTR, 10) @[User::Execution_Id]
For failure:"UPDATE dbo.Audit
SET end_time = CAST('"+(DT_WSTR, 30) @[User::execution_end_date] +"' AS DATETIME),status = 'Failed'
where execution_id ="+ (DT_WSTR, 10) @[User::Execution_Id]
