How do I count how many times a word appears in SQL?
T-SQL doesn’t provide a built-in function to count the number of times a particular string appears within another string, so to find out how many times a word appears in a row, you have to build your own count function. SQL Server 2000 lets you create this kind of user-defined function (UDF).

COUNT(*) or COUNT(1) The difference is simple: COUNT(*) counts the number of rows produced by the query, whereas COUNT(1) counts the number of 1 values. In general, you should always use COUNT(*).

Which is faster COUNT (*) or COUNT 1?
