我需要将以下SQL Server存储过程转换为MySQL。我是MySQL的新手。
CREATE PROC InsertGenerator
(@tableName varchar(100)) as
--Declare a cursor to retrieve column specific information
--for the specified table
DECLARE cursCol CURSOR FAST_FORWARD FOR
SELECT column_name,data_type FROM information_schema.columns
WHERE table_name = @tableName
OPEN cursCol
DECLARE @string nvarchar(3000)
--for storing the first half
--of INSERT statement
DECLARE @stringData nvarchar(3000)
--for storing the data
--(VALUES) related statement
DECLARE @dataType nvarchar(1000) --data types returned
--for respective columns
SET @string='INSERT '+@tableName+'('
SET @stringData=''
DECLARE @colName nvarchar(50)
FETCH NEXT FROM cursCol INTO @colName,@dataType
IF @@fetch_status<>0
begin
print 'Table '+@tableName+' not found, processing skipped.'
close curscol
deallocate curscol
return
END
WHILE @@FETCH_STATUS=0
BEGIN
IF @dataType in ('varchar','char','nchar','nvarchar')
BEGIN
SET @stringData=@stringData+'''''''''+
isnull('+@colName+','''')+'''''',''+'
END
ELSE
if @dataType in ('text','ntext')
--if the datatype
--is text or something else
BEGIN
SET @stringData=@stringData+'''''''''+
isnull(cast('+@colName+' as varchar(2000)),'''')+'''''',''+'
END
ELSE
IF @dataType = 'money' --because money doesn't get converted
--from varchar implicitly
BEGIN
SET @stringData=@stringData+'''convert(money,''''''+
isnull(cast('+@colName+' as varchar(200)),''0.0000'')+''''''),''+'
END
ELSE
IF @dataType='datetime'
BEGIN
SET @stringData=@stringData+'''convert(datetime,''''''+
isnull(cast('+@colName+' as varchar(200)),''0'')+''''''),''+'
END
ELSE
IF @dataType='image'
BEGIN
SET @stringData=@stringData+'''''''''+
isnull(cast(convert(varbinary,'+@colName+')
as varchar(6)),''0'')+'''''',''+'
END
ELSE
--presuming the data type is int,bit,numeric,decimal
BEGIN
SET @stringData=@stringData+'''''''''+
isnull(cast('+@colName+' as varchar(200)),''0'')+'''''',''+'
END
SET @string=@string+@colName+','
FETCH NEXT FROM cursCol INTO @colName,@dataType
END

http://dev.mysql.com/doc/refman/5.0/en/stored-routines-syntax.html 此链接包含有关在MySql中创建存储过程和函数的文档。你有相当多的代码,所以它可能会降到1和6的另外6个。

您可以使用以下步骤将其转换为MySQL。
在SQL Server中,存储过程的参数声明为
例如:
CREATE PROCEDURE Strproc_example( @strBillingPeriodID VarChar(200), @result int OUT)
在MySQL中它是
CREATE PROCEDURE Strproc_example( v_strBillingPeriodID VarChar(200), OUT v_result int)
在SQL Server中有As
个关键字。在MySQL
然后在SQL Server语句后面加一个分号进行转换 进入MySQL语句。
