Stitch QA Queries

The SQL Segment Editor is an optional interface that allows you to build an attribute profile with SQL. Start with a SELECT statement that returns the Amperity ID, and then apply a series of WHERE statements to define one (or more) attribute groups that match specific conditions and values.

Add queries

Queries may be authored using the Visual Query Editor or the SQL Query Editor. Click Create and then select the query editor to open. Queries that are already created have an icon that shows from which query editor they were authored. All queries must be activated before they can run as part of a scheduled workflow.

To add a SQL query

  1. From the Queries tab click Create, and then select SQL Query. This opens the SQL Query Editor.

  2. Under Database, select a database. The Customer 360 database is selected by default.

  3. Define the query against the selected database.

  4. Click Run Query and debug any issues that may arise.

  5. Click Activate.

Semantic values

Use regular expressions to create additional fields based on semantic values and to clean up semantic values, as necessary.

To keep only alphabetical characters

  REGEXP_REPLACE(AddressLine1, '(\s*)([^a-zA-Z0-9])', '')
FROM Customer360

To replace characters after + symbol

,REGEXP_REPLACE(LOWER(email), '\+(.*?)\@', '@') AS email

To keep characters before @ symbol

,SPLIT(REGEXP_REPLACE(LOWER(email), '\+(.*?)\@', '@'), '@')[1] AS email_username

To keep characters after @ symbol

,REPLACE(LOWER(email), SPLIT(REGEXP_REPLACE(LOWER(email), '\+(.*?)\@', '@'), '@')[1], '') AS email_domain

To clean up semantic values

,REGEXP_REPLACE(LOWER(phone), '[^0-9]+', '') AS phone
,REGEXP_REPLACE(LOWER(address), '[.]+', '') AS address
,REGEXP_REPLACE(LOWER(address2), '[.]+', '') AS address2
,REGEXP_REPLACE(LOWER(city), '[^a-zA-Z]+', '') AS city
,REGEXP_REPLACE(LOWER(state), '[^a-zA-Z]+', '') AS state
