We discuss each of them briefly: Using the SOUNDEX function: The SOUNDEX (string) function calculates the Soundex code for a string in SQL Server as follows: So we can use it easily in the SELECT statement and in the WHERE clause, as follows: The DIFFERENCE() function compares two different SOUNDEX values, and return the value of the integer.This value measures the degree that the SOUNDEX values match, on a scale of 0 to 4. A value of 0 indicates a weak or no similarity between the SOUNDEX values; 4 indicates that the SOUNDEX values are extremely similar, or even identical. It's worth noting that SQL Server exhibits some odd behavior here - although SQRT(VARP(expression)) is logically equivalent to STDEVP(expression), interestingly and I suspect due to rounding, truncation or arithmetic errors to do with SQRT, the two values are NOT identical when computed in SQL Server - they vary by a small amount. What this statement does is to find similar "sounding" names in the database by ignoring all vowels and converting the strings into four-digit codes where comparison can be made.

SOUNDEX('Wlliams') === 'W452' This means that we can allow users to search for misspellings on the last_name field by modifying the SQL query as follows: SELECT * FROM `people` where SOUNDEX(`last_name`) = SOUNDEX('Wlliams') Summary: in this tutorial, you will learn how to use the SQL Server DIFFERENCE() function to compare two SOUNDEX() values of two strings. ; forum discussion soundex clause - The MySQL Relational Database Training, … Thus is the reason for a SQL Server implementation of Double Metaphone: not everyone will need it at all, but there will be situations when it is the best, or only, option for a phonetic matching system. This value measures the degree that the SOUNDEX The solution, I soon discovered, was SQL Server's SOUNDEX statement. Comparing a column to NULL using the = operator is undefined. For example, you can use the COLLATE clause in a T-SQL SELECT statement to specify the collation to … The following String Soundex query shows you multiple ways to use this function.

Collation can also be applied to a character string expression to apply a collation cast. NULL is a special value that signifies 'no value'. The CASE statement goes through conditions and returns a value when the first condition is met (like an IF-THEN-ELSE statement). Note. Implicit type conversion of UDTs for system operators and functions, including SOUNDEX, is a Teradata extension to the ANSI SQL standard. Soundex - Experiments with SQL CLR. There are two books that have had such a profound effect on me. The Soundex Function returns the Soundex code value of a user-specified string expression. SQL Server LIKE operator overview.
