SYMPTOMS
When the Visual FoxPro ODBC driver is used to create a numeric field of width 5 with decimal 2, the driver adds two places to the width in order to ensure that the length is of sufficient size. Two positions are added to compensate for the sign and decimal that is normally included in the length in native Visual FoxPro.



CAUSE
When a table is created with a numeric field, the decimal point and sign are counted in the width by Visual FoxPro. However, the ODBC standards do not specify how the decimal and sign should be specified when creating a table.



STATUS
This behavior is by design.



Steps to Reproduce Behavior
 Create a datasource named temp that is set up for free tables and that points to the C:\Temp directory.  Run the following program: h=SQLCONNECT("temp","","") ?SQLEXEC(h,"CREATE TABLE ztest (nfield N(5,2))") ?SQLDISCONNECT(h) USE c:\temp\ztest MODIFY STRUCTURE 

Notice that the width is 7 instead of 5. The width was increased by two.
