SQL VLOOKUP is not a standard feature in SQL databases, as it is more commonly seen in spreadsheet software like Microsoft Excel. However, in SQL databases, you can achieve similar functionality using JOIN statements to combine data from multiple tables based on a common key.

In a distributed database, the concept of VLOOKUP may still be applicable, but the implementation would depend on the specific database system being used and how data is distributed and stored across nodes. In a distributed database environment, data may be partitioned across multiple nodes, so querying data from multiple tables may involve querying data from different nodes and combining the results.

Overall, the concept of VLOOKUP can be applied in a distributed database environment, but it may require a different approach and implementation compared to traditional SQL databases.
