Unlike any other database, Netezza nzsql supports the pattern matching. You can search for the string by matching particular patterns. The Netezza LIKE statement expression is most commonly used in pattern matching. The Netezza LIKE statement returns true if the string contained in the set if strings or table columns that are represented by the […]
If you ever wondered how to verify how similar or different strings are. The Netezza SQL language supports two Netezza fuzzy string search functions: Levenshtein Edit Distance and Damerau-Levenshtein Edit Distance. You can perform the fuzzy search with help of these functions. Basically, Netezza fuzzy string search function supports a search in a form of […]
System uses the Netezza GENERATE STATISTICS command to generate information about each column proportion of the duplicate,and maximum and minimum values.
You can use Netezza hash function to encode the data by transforming the input into a hash code or hash values. If you use the hash function, no two inputs have same hash values. The hash algorithm is designed to minimise the collision (two inputs having same hash value). You can use the hash function […]
