copied!<p>My solution would be to create a UDF that will parse the CSV data into a table variable. Then, in the SP, retrieve the CSV, pass it to the UDF, then run the query against the table variable.</p> <p>First, create a UDF to return a table from the CSV value (uses CHAR(13) to determine new lines, may need to be altered to work with your data):</p> <pre><code>CREATE FUNCTION [dbo].[fnParseCSV] (@InputString NVARCHAR(MAX), @Delimiter NCHAR(1) = ',') RETURNS @tbl TABLE (ID int, Val NVARCHAR(64)) AS BEGIN declare @singleLine nvarchar(max) declare @id int declare @val varchar(64) WHILE LEN(@InputString) > 0 BEGIN IF CHARINDEX(char(13), @InputString) > 0 BEGIN SELECT @singleLine = SUBSTRING(@InputString, 1, CHARINDEX(char(13), @InputString) - 1) IF CHARINDEX(@Delimiter, @singleline) > 0 BEGIN SELECT @id = convert(int, SUBSTRING(@singleline, 1, CHARINDEX(@Delimiter, @singleline) - 1)) SELECT @val = RIGHT(@singleline, LEN(@singleline) - CHARINDEX(@Delimiter, @singleline) ) INSERT INTO @tbl (id, val) values (@id, @val) END SELECT @InputString = RIGHT(@InputString, LEN(@InputString) - CHARINDEX(char(13), @InputString) ) END ELSE BEGIN IF CHARINDEX(@Delimiter, @inputString) > 0 BEGIN SELECT @id = convert(int, SUBSTRING(@inputString, 1, CHARINDEX(@Delimiter, @inputString) - 1)) SELECT @val = RIGHT(@inputString, LEN(@inputString) - CHARINDEX(@Delimiter, @inputString) ) INSERT INTO @tbl (id, val) values (@id, @val) END set @inputString = '' END END RETURN END </code></pre> <p>Then run the query against that output:</p> <pre><code>select * from dbo.fnParseCsv('123,val1' + char(13) + '456,val2' + CHAR(13) + '789,val3', ',') </code></pre>
