SQL how to decompose strings according to the specified delimiter, for this problem, this article details the corresponding analysis and solution, hoping to help more small partners who want to solve this problem find a simpler and easier way.

If you have a string eg: "sun,star,moon,clouds" and you want to break this string into elements [sun] [star] [moon] [clouds] in MS SQL according to the given delimiter ',' how do you do that? To do this, create a Function with the following code: Copy the code with the following code: CREATE FUNCTION [dbo]. [Split_StrByDelimiter](@String VARCHAR(8000), @Delimiter CHAR(1)) RETURNS @temptable TABLE (items VARCHAR(8000)) AS BEGIN DECLARE @idx INT DECLARE @slice VARCHAR(8000) SELECT @idx = 1 IF len(@String)0) INSERT INTO @temptable(Items) VALUES(@slice) SET @String = RIGHT(@String,len(@String) - @idx) IF len(@String) = 0 break END RETURN END

Examples: If SELECT * FROM dbo.Split_StrByDelimiter ('sun,star,moon,clouds',',') returns sun star moon clouds in the above code deformation, returns how many elements copied code is as follows: CREATE FUNCTION [dbo]. [GetCount_Split_StrByDelimiter](@String VARCHAR(8000), @Delimiter CHAR(1)) RETURNS INT AS BEGIN DECLARE @temptable TABLE (items VARCHAR(8000)) DECLARE @SplitCount INT DECLARE @idx INT DECLARE @slice VARCHAR(8000) SELECT @idx = 1 IF len(@String)0) INSERT INTO @temptable(Items) VALUES(@slice) SET @String = RIGHT(@String,len(@String) - @idx) IF len(@String) = 0 break END SET @SplitCount=(SELECT COUNT(*) FROM @temptable) RETURN @SplitCount END

Example SELECT dbo.GetCount_Split_StrByMinimiter ('sun,star,moon, clouds',',') Returns 4
