我在Delphi 7中有一个项目,我TAdoQuery.ParseSql();用来加载参数.现在我在XE4中编译它,参数类型有时是错误的.这真的是ftInteger创造了ftSmallint.我该怎么做才能解决这个问题？我的数据库是SQL Server 2008 R2.

表定义:

   [Code] [nvarchar](50) NOT NULL, 
   [Name] [nvarchar](500) NOT NULL, 
CONSTRAINT [PK_tblTest] 
PRIMARY KEY CLUSTERED ( [sysId] ASC )
   WITH ( PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, 
          ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON ) 
   ON [PRIMARY] )
ON [PRIMARY]

样本数据:

INSERT INTO tblTest ( Code, Name ) VALUES ( 'a1', 'name1' )

德尔福代码:

ADOQuery.SQL.Text := 'SELECT * FROM tblTest …
