To represent an AND relationship between two or more fields on a QBE (Query By Example) grid, you should place the criteria on separate lines.

Question

BlackTom AI · Accepted Answer

Consider the statement about representing an AND relationship in a QBE (Query By Example) grid. 
Option 1: True. The claim says you should place criteria on separate lines to achieve an AND relationship between fields. In many QBE implementations, placing criteria on the same row but in different fields represents an AND condition across those fields, whereas placing criteria on separate rows typically represents an OR condition between the rows. Therefore, this option misstates how QBE typically encodes AND logic, making it incorrect. 
Option 2: False. This option aligns with the common behavior of QBE grids: to express an AND relationship across different fields, you place each field's criterion on the same row (i.e., on the same horizontal line) corresponding to the same query row, so the criteria are combined with AND. When criteria are placed on separate rows, the rows are treated as alternative conditions, effectively producing an OR relationship between them, not AND. 
In summary, the intuitive rule is that AND is represented by keeping criteria on the same row across fields, whereas separate rows invoke OR between the rows, which contradicts the statement in Option 1. 
Thus, Option 1 is incorrect because it reverses how AND is typically implemented in a QBE grid, and Option 2 correctly reflects the standard interpretation of rows and columns in QBE for combining criteria.
