This will launch SQL Server Import and Export Wizard On Object Explorer window right click on database on context menu follow menu options Tasks > Export Data.
Launch SQL Server Management Studio and connect to source SQL Server database. When using COPY command with this role, S3 service validates the incoming request for authorization to read CSV file in target bucket.Īfter the SQL command is commited the new entries can be displayed by executing SQL Select query on Redshift database table.Īs a second example, I want to show how SQL Server database developers can export table data as CSV file.Īnd how Amazon Redshift SQL developers can use COPY command with "EXPLICIT_IDS" option to import data with Identity values from AWS S3 bucket. On AWS Management Console, if you open Amazon Redshift service dashboard and list Clusters created in that region, when you select the target Redshift cluster and click on Manage IAM Roles button, you will be able to assign or display the IAM role attached to that Redshift cluster. The file path information is as follows " s3://bucketname/full-filename-path"Īn important parameter for the COPY command is the IAM_ROLE which enables Amazon Redshift AWS service to reach and read files in S3 bucket. In the COPY command from parameter indicates the address of the file in S3 bucket. Since the file format is CSV in SQL COPY command I used the csv file format option.Īdditionally, since the exported data is saved with header line which contains the column names of the data, I used ignoreheader option with line number as 1
Now Amazon Redshift SQL developers can launch their favorite SQL Editor and execute following COPY command on target Redshift databaseįrom 's3://kodyaz-redshift-data-transfer/ActivityID.csv' You can use AWS Management Console for the file upload. Since my data includes only numeric values, during CSV file creation I did not choose a specific encoding and directly saved the file as CSV (Comma delimeted) (*.csv) file.Īfter data file in csv format is created upload file to an Amazon S3 bucket.
When the data that you want to transfer or insert into Amazon Redshift table is listed as output of the SELECT query on SQL Server Management Studio, right click on on context menu choose option " Save Results As." Inserting IDENTITY column values with COPY command requires additional parameter EXPLICIT_IDSīut for this Redshift SQL COPY command sample, database developers will not require this option.įirst, I query table data using SELECT command to enable you to see the data structure too.Īlthough this is not a must, let's continue like this. Please note that the table does not have IDENTITY column. For the sake of simplicity our first example will be based on a simple SQL Server database table with one column.
