SYMPTOMS
Properties for table columns in Data View show numeric codes under Data Type in the Column Properties dialog box. The Type field of the same dialog box displays the text version of the column type.



CAUSE
The ODBC API SQLGetTypeInfo returns these numbers. The return code is displayed without displaying the constant name for the SQL data type (SQL_CHAR, SQL_INTEGER, and so on).



RESOLUTION
Open the header file Sql.h, which lists the constant names for the SQL data type codes, in the MSDEV\include subdirectory. A partial list is given below: /* Standard SQL datatypes, using ANSI type numbering */ ..
 * 1) define SQL_CHAR                       1
 * 2) define SQL_NUMERIC                    2
 * 3) define SQL_DECIMAL                    3
 * 4) define SQL_INTEGER                    4
 * 5) define SQL_SMALLINT                   5
 * 6) define SQL_FLOAT                      6
 * 7) define SQL_REAL                       7
 * 8) define SQL_DOUBLE                     8
 * 9) define SQL_VARCHAR                    12



STATUS
Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. This problem has been fixed in Visual C++ version 5.0.



MORE INFORMATION
To reproduce the behavior, insert a SQL Server data source connecting to the pubs sample database:


 * 1) In the data source pane, open the authors table so that each column name is displayed.
 * 2) Display the properties page, pin it in place, and click the various column names.

Note: The data types are shown as 1, -7, 12, and perhaps others. These are the SQL type ids for the various SQL types. The type name is listed elsewhere in the properties page. Other tables show the same problem.
