Use this Snap to combine the incoming SQL queries and add an a UNION ALL or UNION DISTINCT SQL operator between them. The UNION ALL SQL operator is used to combine the result of two or more SQL SELECT statements. The UNION DISTINCT SQL operator does the same and removes duplicate rows.
This Snap also allows you to preview the result of the output query. You can validate the modified query using this preview functionality.
Prerequisites
- Two or more SQL SELECT queries.
- The source tables in the SQL SELECT statements must have the same number of columns.
- The column data types of each of the source tables also need to match.
