Hi,
Can you give some sample data for the field


>Here's an unusual question (or at least this seems unusual to me):
>
>I have a VFP table that contains (among other things) a character field containing the values 0-50 as well as the values A-Z.
>
>In this client's data, A-Z represents quantifiable values less than zero, even though this field is a character field in the table.
>
>Assuming the table name is "mytable" and the character field I am referring to is named "myfield", If I wanted to select all records where myfield contains a "value" less than "D" for example, how would I do so? I can't change the structure of the table, etc (tons of legacy data) and if I run a select statement such as:
>
>Select * from mytable where myfield < "2"
>
>then I obviously get records back where myfield = "12", "19", etc (since the data is stored as a character, "12" is seen as less than "2", etc). Using VAL() on the field in advance doesn't work as part of the SQL-Select statement.
