Which operator can be used for comparison in USQL?

• A. BIN
• B. !=
• C. CONTAINS
• D. LIKE

Answer: (B)

In USQL, the operator used for comparison is the "!=" operator. This operator is employed to evaluate inequality between two values. When you want to determine if one value is not equal to another, the "!=" operator performs this function effectively, allowing for straightforward comparisons in queries. Using "!=" is particularly useful for filtering data sets where specific criteria must be met, excluding records that match a particular value. This type of comparison is essential in data processing, as it provides the means to refine results according to desired conditions. Other operators listed, while they serve different purposes in querying and data manipulation, do not perform simple value comparison. For instance, "CONTAINS" is used for string search operations, which checks if one string contains another substring, while "LIKE" is employed for pattern matching. The "BIN" operator, on the other hand, is more related to binary operations, rather than direct value comparison. Thus, the correct choice of "!=" reflects its role in establishing inequality between values in USQL.
