[V4RB] Unable to delete rows

[Marco Bambini]

This is my table:

sql = "CREATE TABLE LOG ("
sql = sql + "SKU ULong NOT NULL UNIQUE INDEXED,"
sql = sql + "Username String(50,'ASCII'),"
sql = sql + "DateLog Date INDEXED,"
sql = sql + "TimeLog Time,"
sql = sql + "Value VarChar(1024,'ASCII')"
sql = sql + ");"
...

The following command has no effect (also typed in ViSQL):

Delete from LOG WHERE DateLog<=A_Correct_Date_Value

Is this a bug? I am using V4RB 1.9.7b5 with RB 4.5.3fc2 (Carbon version)
