![]() For example, I ran the above example statements against the Application.Cities table with more than 37,000 records in WideWorldImporters database and obtained the actual execution plan. Large strings like varcher(max) and nvarchar(max) are not accepted.Īs mentioned above in the comparison, performance wise, using LIKE will be slower compared to CONTAINS. Pattern used for comparison is a string which can have a maximum of eight thousand bytes. Since wildcards can be used only at the end, performance should be faster as it can use indexes like the full-text index. Performance may be slower if you use wildcards at the beginning of the pattern as it may not be able to use any of the indexes. ![]() The wildcard asterisk (*) will work only if it is used at the end of the word or phrase. Example: ‘%Some Phrase%’, ‘_ome Phrase’, ‘ome Phrase’, ‘Some P%’, etc. The wildcard characters can be used in different places of the pattern as needed. The only wildcard character which can be used is asterisk (*). You can use regular characters or wildcard characters like %, _, and in a pattern It performs full-text search only on full-text indexed columns. It does not need the column to be indexed. ![]() LIKE is an operator which is used to find whether a character string matches a specified pattern.ĬONTAINS is a predicate which can be used to search for a word, prefix of a word, a word near another word, synonym of a word, etc. WHERE CONTAINS (CityName, '"Xenia" or "Yale"') WHERE CityName LIKE 'Xenia' OR CityName LIKE 'Yale'
