Compares two expressions (a comparison operator). When you compare nonnull expressions, the result is TRUE if the left operand has a value higher than the right operand; otherwise, the result is FALSE.

Syntax
Greater_Than_Operator :=                                                                                 
    expression '>' expression.

Semantics of Syntax Elements

  • expression
    Is any valid expression. Both expressions must have implicitly convertible data types.

Return Type

Boolean.

Examples

  • The examples can be executed in Visual Studio with the Azure Data Lake Tools plug-in.
  • The scripts can be executed locally. An Azure subscription and Azure Data Lake Analytics account is not needed when executed locally.

Greater Than with Numeric and Temporal Types

@somePeople = 
    SELECT * FROM 
        ( VALUES
        (1, "Noah",    100, (int?)10000, new DateTime(2012,05,31)),
        (2, "Sophia",  100, (int?)15000, new DateTime(2012,03,19)),
