海外TECH	DEV Community	Nulls are equal in distinct but inequal in unique.	https://dev.to/nightbird07/nulls-are-equal-in-distinct-but-inequal-in-unique-52me	Nulls are equal in distinct but inequal in unique While developing ETL pipelines for a new data warehouse I encountered unexpected query results related to NULL values This prompted me to delve into the underlying SQL behavior to better understand the discrepancy In this article I aim to elucidate the contrasting treatment of NULLs by the DISTINCT and UNIQUE keywords I ll present examples based on my analysis of the data warehouse DISTINCT Treating Null as EquivalenceWhen I sought to explore the categories or ranges of values within a specific columnーlet s say the jobs columnーthe initial result appeared as follows doctor engineer null This outcome raised a question Does this mean that there is only a single NULL value My previous understanding of PostgreSQL led me to believe that NULL values are treated as distinct However when I meticulously counted the occurrences of NULL values in the jobs column using the query SELECT COUNT as nulljobs FROM jobs WHERE jobs IS NULL The result unveiled a surprising rows containing NULL values It seemed that DISTINCT treated NULL values as equivalent There could be a reasonable explanation for this behavior The DISTINCT operation is typically employed for visualization or categorization purposes Hence treating NULLs as distinct might not make practical sense However this raises the question of why NULLs are treated as distinct values in the first place This treatment is rooted in the concept of Three Valued Logic VL which consists of true false and unknown Crucially unknown is not equal to unknown in this context Keep in mind that the comparison unknown unknown doesn t hold To shed light on this consider that infinity infinity equals infinity This implies that unknown values can be aggregated into a single value or category UNIQUE Constraints Ensuring Uniqueness Among ColumnsThe behavior of NULL values under the UNIQUE constraint in PostgreSQL introduces interesting nuances UNIQUE constraints are particularly tailored for use with partial indexes In this specific context the interpretation of NULL values differs significantly Rather than serving as indicators of mean or central tendencies NULL values under UNIQUE constraints embody the distinctiveness of other non null values within a row As a result UNIQUE constraints do not revolve around the treatment of NULL values in isolation Instead they focus on preserving distinctions among values contained within individual rows To illustrate this point further let s consider a practical scenario involving a PostgreSQL database Suppose we have a table named employees with columns employee id and email We want to ensure that each email address in the email column is unique However NULL values should not interfere with this uniqueness requirement CREATE TABLE employees employee id serial PRIMARY KEY email VARCHAR UNIQUE Create a partial index to enforce uniqueness among non null idsCREATE UNIQUE INDEX unique email ON employees email WHERE email IS NOT NULL In this case PostgreSQL will enforce the UNIQUE constraint on the email column allowing multiple NULL values This aligns with the concept that the UNIQUE constraint is chiefly concerned with maintaining the distinctiveness of non null values For instance the following insertions are valid Valid insertionsINSERT INTO employees email VALUES john example com INSERT INTO employees email VALUES mary example com INSERT INTO employees email VALUES NULL However attempting to insert duplicate non null values would result in a violation of the UNIQUE constraint Invalid insertion due to violation of UNIQUE constraintINSERT INTO employees email VALUES john example com when you SELECT some info using the partial index already made with EXPLAIN it is performing an index scan EXPLAIN SELECT FROM employees WHERE email IS NOT NULL Summary and ConclusionSure I can help you write a summary and conclusion for your article Here is a possible way to end your article Summary and ConclusionDISTINCT allows duplicate NULLs in the result set as it considers NULLs as distinct values that represent unknown or missing data This behavior is based on the three valued logic of SQL where unknown is not equal to unknown UNIQUE constraints treat NULLs as equal as they enforce uniqueness among non null values in a column or a set of columns This behavior is useful for creating partial indexes that exclude NULL values from the index The difference between DISTINCT and UNIQUE has an impact on the query performance and data integrity as it affects how the data is filtered sorted and indexed Developers should be aware of this difference and use appropriate techniques to handle NULL values in their queries	2023-08-29 11:27:57
