Dear Friend If we use an INSERT commandEach time a new row is inserted into the table.... If the table has 4 fields and we insert a row with 2 values....the other two fields are automatically given NULL values ..Provided those fields are not identity columns. And We cannot Use WHERE clause in a direct insert command.. SO it is better to use UPDATE command incase of partial input where we can specify the particular row with some identity.. EXAMPLE update table2 set fldLength=10 and fldSize=25 where fldName=filename.Name Al d best wit prayers Satisa....
