  1. Whitelist the following IP addresses for your cluster:
  • ~Main Cluster: {% dropdown-button name="main" %}

{% dropdown-body name="main" %}

Due to the limitations of the ```ORDER BY``` clause in Azure SQL, you must be careful with the choice of breakdowns such as ```text``` and ```ntext```, as it will become more expensive due to the ```CAST``` operation (e.g, for ```text``` type, we’ll cast it to ```text -> varchar(max)```). Please carefully consider the performance implications and potential alternatives before including these breakdowns in your extraction.


How to extract data from Azure SQL

Step 1 - Select table

  1. Select a table from the schema you specified during authorization.
  1. Click Continue to proceed to the next step.

Step 2 - Match

  1. Enter your Data Table name. Remember, you can't change this later.
  2. Select Sync historical data period. This setting allows you to extract historical data from the selected date range during the initial data extraction.
  1. Configure your Extraction scheduling. Allows you to set how often your data is extracted to Improvado storage.
  1. Select the columns you need to import. By default, all columns are selected.
  1. Check the column type. Each column in a data table can be assigned a String, Number, or Date type.
  2. ~The date column is a unique date-key in the database and should be singular. You have the flexibility to choose from a wide range of date formats for this column.
  3. ~If you have column with numeric values that you don't want to include in your calculations, change the type from Number to Text.

  1. The Skip rule allows you to exclude empty rows and rows with specific values in a selected column:
  2. ~Default to 'Do Not Skip': Ensures all data is initially included.
  3. ~Multi-Select Options: Combine 'Skip: empty' and 'Skip: value' for targeted exclusions. Selecting 'Do Not Skip' disables other skip options.
  4. ~Custom Rule addition: Add one custom rule; the form is disabled afterward to maintain focus
  5. ~Custom Rule deletion:  Hover over and click on the red-highlighted basket icon next to the rule to exclude it.

Usage Note: the component is designed for straightforward value-based selections and does not support complex expressions like '<10'.

  1. Click on the Import N columns button to continue.
