我怎样才能将这个sql server存储过程的等价物写入mysql？

Question

我的sql server的存储过程代码是：

ALTER procedure [dbo].[MasterReport_SP]
(@masterReportRecNo bigint)
AS
DECLARE @updateDateCriteria varchar (500)
DECLARE @spCriteria varchar (3000)
DECLARE @sqlCommand1 varchar(3000)
DECLARE @sqlCommand2 varchar(3000)
DECLARE @sqlCommand3 varchar(3000)
DECLARE @transNo varchar (50)



BEGIN TRY


if @underwriterState = ''
begin
set @underwriterState = null
end

Set @totalEndtPremium = 0

Set @sqlCommand1 = ''

if @updateDateCriteria is NOT NULL
begin
if @underwriterState is NOT NULL
    begin
    Set @sqlCommand1 = 'DECLARE transDetails Cursor for Select policyNumber, policyTerm from trans'
    end
else
    begin
    Set @sqlCommand1 = 'DECLARE transDetails Cursor for Select policyNumber, policyTerm, policyIssueDate from trans'
    end
end

IF @sqlCommand1 is NOT NULL
BEGIN
    EXEC (@sqlCommand1)
    OPEN transDetails
    FETCH NEXT FROM transDetails INTO @policyNumber, @policyTerm, @policyIssueDate, @transactionNo
    WHILE @@FETCH_STATUS = 0
        BEGIN
            Print @policyNumber
            Set @systemCalcPremium = 0
            Set @premium = 0

        end;

由于这条线，我面临问题： 设置@sqlCommand1 =＆＃39; DECLARE transDetails Cursor for select policyNumber，policyTerm from trans＆＃39; 。因为mysql不允许这样做。是否有任何替代此行MySQL的。
