Specifies how a query can compare the columns in a table, including literal comparisons and column-to-column comparisons.
Contents
- allowedColumnComparisonColumns
-
The columns that a query can compare to another column, for example, in a join, a WHERE clause, a GROUP BY clause, or a window function. AWS Clean Rooms rejects a query that uses any other column in a column-to-column comparison. Specify an empty list to block column-to-column comparison on every column.
Type: Array of strings
Length Constraints: Minimum length of 1. Maximum length of 127.
Pattern:
[a-z0-9_](([a-z0-9_ ]+-)*([a-z0-9_ ]+))?Required: Yes
- allowedLiteralComparisonColumns
-
The columns that a query can compare to literal values, for example, in a WHERE clause. AWS Clean Rooms rejects a query that compares any other column to a literal value. Specify an empty list to block literal comparison on every column. You can't specify a column that you also use as an identity column in an aggregation threshold.
Type: Array of strings
Length Constraints: Minimum length of 1. Maximum length of 127.
