In SQL a null value is undefined or inapplicable or the field has no value assigned or defined. It is not equal to zero or space. Zero is a number and space is a character. Null is undefined value.

If a table field is null you see a value like null when you run a query which fetches data from that table.

If you want to see only specific columns you have to issue the sql command like this [GENERIC FORMAT] SELECT column1,column2 from TABLENAME column1 & column2 are column names in the table. SELECT PlotID,TreeTagNumber from trees; This command displays only PlotID and TreeTagNumber from above table. The output will be like this +------------------------------------OUTPUT------------------------------------------+ PlotID TreeTagNumber 110 461 110 462 110 465 110 466 110 467 110 468 110 469 110 470 110 471 110 472 +-------------------------------------------+------------------------------------------+
