can anybody help me to write the following MS-SQL sp to MySQL sp,
use of this:
CREATE PROCEDURE sp_InputWork
#_DelimitedString nvarchar(MAX)
AS
BEGIN
SET NOCOUNT ON;
DECLARE #_DataRow nvarchar(MAX)
DECLARE #_DescriptionOfWorkDone nvarchar(MAX)
DECLARE #_TemporaryStorage nvarchar(MAX)
DECLARE #_QTY int
DECLARE #_Total int
DECLARE #_CurrentField int
WHILE CHARINDEX(';', #_DelimitedString) > 0
BEGIN
SET #_DataRow = CAST(SUBSTRING(#_DelimitedString, 0, CHARINDEX(';', #_DelimitedString)) AS nvarchar(MAX))
SET #_CurrentField = 1
WHILE CHARINDEX(',', #_DataRow) > 0
BEGIN
SET #_TemporaryStorage = CAST(SUBSTRING(#_DataRow, 0, CHARINDEX(',', #_DataRow)) AS nvarchar(MAX))
IF #_CurrentField = 1
SET #_QTY = CAST(#_TemporaryStorage AS int)
IF #_CurrentField = 2
SET #_DescriptionOfWorkDone = #_TemporaryStorage
IF #_CurrentField = 3
SET #_Total = CAST(#_TemporaryStorage AS int)
SET #_DataRow = SUBSTRING(#_DataRow, CHARINDEX(',', #_DataRow) + 1, LEN(#_DataRow))
SET #_CurrentField = #_CurrentField + 1
END
INSERT INTO tblWorkDone (QTY, DescriptionOfWorkDone, Total) VALUES (#_QTY, #_DescriptionOfWorkDone, #_Total)
SET #_DelimitedString = SUBSTRING(#_DelimitedString, CHARINDEX(';', #_DelimitedString) + 1, LEN(#_DelimitedString))
END
END
I have changed the SP to Mysql
BEGIN
DECLARE _DataRow VARCHAR(21000);
DECLARE _DescriptionOfWorkDone VARCHAR(21000);
DECLARE _TemporaryStorage VARCHAR(21000) ;
DECLARE _QTY int;
DECLARE _Total int;
DECLARE _CurrentField int;
WHILE INSTR(_DelimitedString, ';') >0 DO
SET _DataRow = CAST(SUBSTRING(_DelimitedString, 1, INSTR(_DelimitedString,';' )) AS CHAR);
SET _CurrentField = 1;
WHILE INSTR(_DataRow,',' ) > 0 DO
SET _TemporaryStorage = CAST(SUBSTRING(_DataRow, 1, INSTR(_DataRow,',' )-1) AS CHAR);
IF _CurrentField = 1 then
SET _QTY = CAST(_TemporaryStorage AS UNSIGNED);
end if;
IF _CurrentField = 2 then
SET _DescriptionOfWorkDone = _TemporaryStorage;
end if;
IF _CurrentField = 3 then
SET _Total = CAST(_TemporaryStorage AS UNSIGNED) ;
end if;
SET _DataRow = SUBSTRING(_DataRow, INSTR( _DataRow,',') + 1, LENGTH(_DataRow));
SET _CurrentField = _CurrentField + 1;
END while;
INSERT INTO tblWorkDone (QTY, DescriptionOfWorkDone, Total) VALUES (_QTY, _DescriptionOfWorkDone, _Total);
SET _DelimitedString = SUBSTRING(_DelimitedString, INSTR(_DelimitedString,';' ) + 1, LENGTH(_DelimitedString));
END WHILE;END

This is my Procure when i execute this Procedure whith input call TestExampl2_SP('a,m,n,x,y,z') i am getting notexistString ='x,y,z' but insetd of this i want result row wise i.e i have to split by comma
like this :
**value**
x
y
z
please suggest me how i will implement this .
You can follow below code to split string in sql.
CREATE FUNCTION SplitString
(
#Input NVARCHAR(MAX),
#Character CHAR(1)
)
RETURNS #Output TABLE (
Item NVARCHAR(1000)
)
AS
BEGIN
DECLARE #StartIndex INT, #EndIndex INT
SET #StartIndex = 1
IF SUBSTRING(#Input, LEN(#Input) - 1, LEN(#Input)) <> #Character
BEGIN
SET #Input = #Input + #Character
END
WHILE CHARINDEX(#Character, #Input) > 0
BEGIN
SET #EndIndex = CHARINDEX(#Character, #Input)
INSERT INTO #Output(Item)
SELECT SUBSTRING(#Input, #StartIndex, #EndIndex - 1)
SET #Input = SUBSTRING(#Input, #EndIndex + 1, LEN(#Input))
END
RETURN
END
And check using
SELECT Item FROM dbo.SplitString('Apple,Mango,Banana,Guava', ',')
I want to convert the following funciton creation to work in MySql
CREATE FUNCTION dbo.DistinctList
(
#List VARCHAR(MAX),
#Delim CHAR
)
RETURNS
VARCHAR(MAX)
AS
BEGIN
DECLARE #ParsedList TABLE
(
Item VARCHAR(MAX)
)
DECLARE #list1 VARCHAR(MAX), #Pos INT, #rList VARCHAR(MAX)
SET #list = LTRIM(RTRIM(#list)) + #Delim
SET #pos = CHARINDEX(#delim, #list, 1)
WHILE #pos > 0
BEGIN
SET #list1 = LTRIM(RTRIM(LEFT(#list, #pos - 1)))
IF #list1 <> ''
INSERT INTO #ParsedList VALUES (CAST(#list1 AS VARCHAR(MAX)))
SET #list = SUBSTRING(#list, #pos+1, LEN(#list))
SET #pos = CHARINDEX(#delim, #list, 1)
END
SELECT #rlist = COALESCE(#rlist+',','') + item
FROM (SELECT DISTINCT Item FROM #ParsedList) t
RETURN #rlist
END
I found this function at http://blog.sqlauthority.com/2009/01/15/sql-server-remove-duplicate-entry-from-comma-delimited-string-udf/
I don't know why people have down graded my question.
Anyway I was able to come up with the answer.
Delimiter //
CREATE FUNCTION DistinctList
(
List TEXT,
Delim CHAR
)
RETURNS
TEXT
BEGIN
DECLARE list1 TEXT;
DECLARE Pos INT;
DECLARE rList TEXT;
DROP TEMPORARY TABLE IF EXISTS ParsedList;
Create temporary table if not exists ParsedList
(
Item VARCHAR(60)
) ENGINE=MEMORY;
SET list = CONCAT(list, Delim);
SET pos = length(SUBSTRING_INDEX(list, delim, 1));
WHILE (pos > 0) DO
SET list1 = SUBSTRING(list, 1, pos);
IF list1 <> '' THEN
INSERT INTO ParsedList VALUES (list1);
END IF;
SET list = SUBSTRING(list, pos+2);
SET pos = length(SUBSTRING_INDEX(list, delim, 1));
END WHILE;
SELECT GROUP_CONCAT(DISTINCT Item) FROM ParsedList INTO rlist;
RETURN rlist;
END//

I have a strange problem with the following SP:
CREATE PROCEDURE [dbo].[Manufacturer_GetProductsCountByManufacturedId]
(
#ManufacturerIds NVARCHAR(MAX) = '',
#ExcludeType INT
)
AS
BEGIN
DECLARE #ManufacturerId NVARCHAR(MAX)
DECLARE #GoodManufacturerIds NVARCHAR(MAX) = ''
DECLARE #result BIGINT
DECLARE #pos INT
DECLARE #len INT
SET #GoodManufacturerIds = ''
SET #pos = 0
SET #len = 0
WHILE CHARINDEX(',', #ManufacturerIds, #pos + 1)>0
BEGIN
-- Split
SET #len = CHARINDEX(',', #ManufacturerIds, #pos+1) - #pos
SET #ManufacturerId = SUBSTRING(#ManufacturerIds, #pos, #len)
-- Check
SELECT TOP 1 #result = p.ProductId
FROM [MYDB].[dbo].[Product] p
INNER JOIN [MYDB].[ProductTyping].[TypedProductFieldValue] tpfv ON tpfv.ProductId = p.ProductId
WHERE ManufacturerId = #ManufacturerId
AND tpfv.ProductTypeId <> #ExcludeType
IF #result > 0
SET #GoodManufacturerIds = #GoodManufacturerIds + #ManufacturerId + ','
SET #pos = CHARINDEX(',', #ManufacturerIds, #pos+#len)+1
END
-- Last comma kaputt
SET #GoodManufacturerIds = LEFT(#GoodManufacturerIds, LEN(#GoodManufacturerIds) - 1)
RETURN #GoodManufacturerIds
END
Basically I have to split a string with comma-separated values and for each on those values, I execute a query and put the result in another comma-separated string.
If I send these values as stored procedure parameters, ("5220,3008,1561,2678," and 5) I got an error, "Unable to cast nvarchar values '5220,3008,1561,2678' to type int".
BUT If I built in those values in the stored procedure as:
DECLARE #ManufacturerId NVARCHAR(MAX)
DECLARE #GoodManufacturerIds NVARCHAR(MAX) = ''
DECLARE #result BIGINT
DECLARE #pos INT
DECLARE #len INT
-- test
DECLARE #ManufacturerIds NVARCHAR(MAX) = ''
DECLARE #ExcludeType INT
SET #ManufacturerIds = '5220,3008,1561,2678,13715,5047,'
SET #ExcludeType = 5
SET #GoodManufacturerIds = ''
SET #pos = 0
SET #len = 0
WHILE CHARINDEX(',', #ManufacturerIds, #pos + 1)>0
BEGIN
-- Split
SET #len = CHARINDEX(',', #ManufacturerIds, #pos+1) - #pos
SET #ManufacturerId = SUBSTRING(#ManufacturerIds, #pos, #len)
-- Check
SELECT TOP 1 #result = p.ProductId
FROM [MYDB].[dbo].[Product] p
INNER JOIN [MYDB].[ProductTyping].[TypedProductFieldValue] tpfv ON tpfv.ProductId = p.ProductId
WHERE ManufacturerId = #ManufacturerId
AND tpfv.ProductTypeId <> #ExcludeType
IF #result > 0
SET #GoodManufacturerIds = #GoodManufacturerIds + #ManufacturerId + ','
SET #pos = CHARINDEX(',', #ManufacturerIds, #pos+#len)+1
END
-- Last comma kaputt
SET #GoodManufacturerIds = LEFT(#GoodManufacturerIds, LEN(#GoodManufacturerIds) - 1)
RETURN #GoodManufacturerIds
Everything works fine and I got my new string.
I dunno where the error could be in the first procedure, any hints?
I found the error, I was using RETURN but RETURN is for integer values and in this case mine is a string, so putting SELECT make everything works fine.
I have write one function but getting this error Not allowed to return a result set from a function

You want to assign the result of a query to a variable, but in fact you're just selecting. That's why MySQL's complaining.
You have to change this
SELECT p_KeyValue = ListName + '.' + Value
FROM ListsTable
WHERE EntryID = p_ParentID LIMIT 1 ;
to
SELECT CONCAT(ListName, '.', `Value`)
INTO p_KeyValue
FROM ListsTable
WHERE EntryID = p_ParentID LIMIT 1 ;
And you should add an ORDER BY. A LIMIT without ORDER BY doesn't make sense, since there's no guaranteed order in a relational database.
Mysql complains about SELECT statement in your function,
probably it understands SELECT p_KeyValue = ListName + '.' + Value as comparison
change it to
SELECT CONCAT(ListName, '.', Value) INTO p_KeyValue
Mysql cursor fetches only first row and when it has fetched the second row the row_not_found variable is set to false and cursor close.
Please look into below SP:
