Its best to include samples to keep the experts from guessing, so I will try to save them some troubles.Ĭapture 'aug' or 'July' or 'JUNE' as whole words if followed by: 1-space, 1-hyphen, 0-or-1 space, and a 1-or-2 digit word. Im no ideas what should be captured, so Im guessing that it should include alternates like.Įxcept that both \W* are redundant since they allow 0-occurrences, so they dont alter any matched text. Texto_Retorno = replace_u_Accents.Replace(Texto_Retorno, " u") Texto_Retorno = replace_o_Accents.Replace(Texto_Retorno, " o") Texto_Retorno = replace_i_Accents.Replace(Texto_Retorno, " i") Texto_Retorno = replace_e_Accents.Replace(Texto_Retorno, " e") Texto_Retorno = replace_a_Accents.Replace(Texto_Retorno, " a") replace_u_Accents = new ( " ", .Compiled) replace_o_Accents = new ( " ", .Compiled) replace_i_Accents = new ( " ", .Compiled) replace_e_Accents = new ( " ", .Compiled) Or an anti-pattern can be achieved by using the LIKE .Regex replace_a_Accents = new ( " ", .Compiled) Such an anti-pattern can involve the creation of a dynamic SQL string in the application layer or in Transact-SQL. The preceding STRING_SPLIT usage is a replacement for a common anti-pattern. They can use following query: SELECT ProductId, Name, Tags WHERE 'clothing' IN (SELECT value FROM STRING_SPLIT(Tags, ',')) įind products with two specified tags (clothing and road): SELECT ProductId, Name, Tagsĭevelopers must create a query that finds articles by a list of IDs. To find products with a single tag (clothing): SELECT ProductId, Name, Tags SELECT value as tag, COUNT(*) AS ĭevelopers must create queries that find articles by keywords. Users must create a report that shows the number of products per each tag, ordered by number of products, and to filter only the tags with more than two products. The order of the output may vary as the order is not guaranteed to match the order of the substrings in the input string. Product table has a column with comma-separate list of tags shown in the following example: ProductIdįollowing query transforms each list of tags and joins them with the original row: SELECT ProductId, Name, value Split comma-separated value string in a column Condition RTRIM(value) '' will remove empty tokens. STRING_SPLIT will return empty string if there is nothing between separator. Parse a comma-separated list of values and return all non-empty tokens: DECLARE NVARCHAR(400) = 'clothing,road,touring,bike' In a practice run, the preceding SELECT returned following result table: valueĮxamples A. If the input string is NULL, the STRING_SPLIT table-valued function returns an empty table.Īs an example, the following SELECT statement uses the space character as the separator: SELECT value FROM STRING_SPLIT('Lorem ipsum dolor sit amet.', ' ') You can filter out any rows that contain the empty substring by using the WHERE clause ( WHERE value ''). Empty substrings are treated the same as are plain substrings.

You can override the final sort order by using an ORDER BY clause on the SELECT statement ( ORDER BY value).Ġx0000 ( char(0)) is an undefined character in Windows collations and cannot be included in STRING_SPLIT.Įmpty zero-length substrings are present when the input string contains two or more consecutive occurrences of the delimiter character. The order is not guaranteed to match the order of the substrings in the input string. STRING_SPLIT outputs a single-column table whose rows contain the substrings. STRING_SPLIT inputs a string that has delimited substrings, and inputs one character to use as the delimiter or separator. The length of the return type is the same as the length of the string argument. Returns nvarchar if any of the input arguments are either nvarchar or nchar. Returns a single-column table whose rows are the substrings. Is a single character expression of any character type (for example, nvarchar(1), varchar(1), nchar(1), or char(1)) that is used as separator for concatenated substrings. Is an expression of any character type (for example, nvarchar, varchar, nchar, or char). To view Transact-SQL syntax for SQL Server 2014 and earlier, see Previous versions documentation.
