我如何转换这从TSQL到MYSQL？(How do I convert this from TSQL

我想设置一个日期查找表在此： http://www.techrepublic.com/blog/datacenter/simplify-sql-server-2005-queries-with-a-dates-table/326但笔者使用T-SQL，而不是MySQL的。

我创建了表，但现在我试图让它来填充。 笔者有这样的：

创建表的语法：

CREATE TABLE DateLookup
 (
     DateKey INT PRIMARY KEY,
     DateFull DATETIME,
     CharacterDate VARCHAR(10),
     FullYear CHAR(4),
     QuarterNumber TINYINT,
     WeekNumber TINYINT,
     WeekDayName VARCHAR(10),
     MonthDay TINYINT,
     MonthName VARCHAR(12),
     YearDay SMALLINT,
     DateDefinition VARCHAR(30),
     WeekDay TINYINT,
     MonthNumber TINYINT
 )






DECLARE @Date DATETIME
 SET @Date = '1/1/1900'     

 WHILE @Date < '1/1/2100'
 BEGIN
     INSERT INTO DateLookup
     (
         DateKey, DateFull, FullYear,
         QuarterNumber, WeekNumber, WeekDayName,
         MonthDay, MonthName, YearDay,
         DateDefinition,
                CharacterDate,
                WeekDay,
                MonthNumber
     )
     SELECT
         CONVERT(VARCHAR(8), @Date, 112), @Date, YEAR(@Date),
         DATEPART(qq, @Date), DATEPART(ww, @Date), DATENAME(dw, @Date),
         DATEPART(dd, @Date), DATENAME(mm, @Date), DATEPART(dy,@Date),
               DATENAME(mm, @Date) + ' ' + CAST(DATEPART(dd, @Date) AS CHAR(2)) + ',   
           ' + CAST(DATEPART(yy, @Date) AS CHAR(4)),
           CONVERT(VARCHAR(10), @Date, 101),
           DATEPART(dw, @Date),
           DATEPART(mm, @Date)

     SET @Date = DATEADD(dd, 1, @Date)
 END

我已经删除了所有的@符号，和它看起来像它可能不喜欢日期作为变量名，但一直没能得到它的运行。

BEGIN
  DECLARE dateInsert DATETIME
     SET dateInsert = "1900-01-01"
     WHILE dateInsert < "2100-01-01" DO

         INSERT INTO DateLookup
         (
             DateKey, DateFull, FullYear,
             QuarterNumber, WeekNumber, WeekDayName,
             MonthDay, MonthName, YearDay,
             DateDefinition,
                    CharacterDate,
                    WeekDay,
                    MonthNumber
         )
         SELECT
             CONVERT(VARCHAR(8), dateInsert, 112), dateInsert, YEAR(@dateInsert),
             DATEPART(qq, dateInsert), DATEPART(ww, dateInsert), DATENAME(dw, dateInsert),
             DATEPART(dd, dateInsert), DATENAME(mm, dateInsert), DATEPART(dy,dateInsert),
                   DATENAME(mm, dateInsert) + ' ' + CAST(DATEPART(dd, dateInsert) AS CHAR(2)) + ',   
               ' + CAST(DATEPART(yy, dateInsert) AS CHAR(4)),
               CONVERT(VARCHAR(10), dateInsert, 101),
               DATEPART(dw, dateInsert),
               DATEPART(mm, dateInsert)

         SET dateInsert = DATEADD(dd, 1, dateInsert)
     END WHILE;
END;

编辑：我想这个应用程序： http://sourceforge.net/projects/tsql2mysql/ ，但它似乎没有任何我的机器上运行。

编辑：失败接近“声明dateInsert DATETIME SET dateInsert =‘1900-01-01’，而”带或不带@符号，有或无日期被更名为dateInsert。

我试图消除“设置dateInsert =”语句并在声明的末尾添加默认为“1900-01-01”替换，但是这是一个没有去。

我试着单双quores，似乎并没有有所作为。

Answer 1:

从文档： DECLARE is permitted only inside a BEGIN ... END compound statement and must be at its start, before any other statements.

这里的东西更接近。 你需要理清语法CONVERT这是在MySQL不同。

DELIMITER $$
CREATE PROCEDURE test()
BEGIN
    DECLARE dateInsert DATETIME;
     SET dateInsert = '1900-01-01';
     WHILE dateInsert < '2100-01-01' DO
        BEGIN
             INSERT INTO DateLookup
             (
                 DateKey, DateFull, FullYear,
                 QuarterNumber, WeekNumber, WeekDayName,
                 MonthDay, MonthName, YearDay,
                 DateDefinition,
                        CharacterDate,
                        WeekDay,
                        MonthNumber
             )

             SELECT
                 CONVERT(VARCHAR(8), dateInsert, 112), dateInsert, YEAR(@Date),
                 DATEPART(qq, dateInsert), DATEPART(ww, dateInsert), DATENAME(dw, dateInsert),
                 DATEPART(dd, dateInsert), DATENAME(mm, dateInsert), DATEPART(dy,@Date),
                       DATENAME(mm, dateInsert) + ' ' + CAST(DATEPART(dd, dateInsert) AS CHAR(2)) + ',   
                   ' + CAST(DATEPART(yy, dateInsert) AS CHAR(4)),
                   CONVERT(VARCHAR(10), dateInsert, 101),
                   DATEPART(dw, dateInsert),
                   DATEPART(mm, dateInsert)

             SET dateInsert = DATEADD(dd, 1, dateInsert)
        END
     END WHILE;
END $$

Answer 2:

更改日期YYYY-MM-DD格式：

DECLARE dateInsert DATETIME
 SET dateInsert = '1900-01-01'

 WHILE dateInsert < '2100-01-01'

....
