Question

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
