  • UNKNOWN as the Datatype when generated(MS ACCESS) MyGeneration

    EntitySpaces Version # 2007.0.0528.0 MyGeneration Version # 1.2.0.7

     Hello,

    I am having  a problem generating my classes. This started yesterday when I added a column to my table. After I regenerate the class using GENERATED CLASSES MASTER(c#), all the datatype is set to UNKNOWN like:

         public virtual bool LoadByPrimaryKey(Unknown line2mapuid)
            {
                if(this.es.Connection.SqlAccessType == esSqlAccessType.DynamicSQL)
                    return LoadByPrimaryKeyDynamic(line2mapuid);
                else
                    return LoadByPrimaryKeyStoredProcedure(line2mapuid);
            }
       

    or
     

    public virtual bool LoadByPrimaryKey(esSqlAccessType sqlAccessType, Unknown line2mapuid)
            {
                if (sqlAccessType == esSqlAccessType.DynamicSQL)
                    return LoadByPrimaryKeyDynamic(line2mapuid);
                else
                    return LoadByPrimaryKeyStoredProcedure(line2mapuid);
            }

    I tried to regenerate class from other table that I did not alter and same thing. I get the UNKNOWN as the datatype.

    I encountered this before but due to a missing primary key on the table. On the generated class, all portions where it supposed to show the datatype, it shows v. I searched the forum and found related only to MySQL.  

    I tried uninstalling Mygeneration and EntitySpaces to no avail. Any help would be appreciated.

     Thanks

    -------------------------------

    Open MyGeneration Default Settings.
    Make sure Microsoft Access is selected in the Driver drop-down.
    Make sure Test Connection is successful.
    In the Language drop-down, select C# (not C# System Types).
    In the DbTarget drop-down, select OleDb.
    Make sure you are using the correct default files:
      C:\Program Files\MyGeneration\Settings\Languages.xml
      C:\Program Files\MyGeneration\Settings\DbTargets.xml
    Click OK.
    Click the MyMeta Browser icon (3rd from left).
    Click the MyMeta Properties icon (5th from right).
    In the MyMeta Browser, navigate down to one of your columns.
    In the Properties pane, is Language Type filled in?
      (They should be int, string, decimal, etc.)
