Use comparison operators to compare character or numeric strings, manipulate data, and return a TRUE (1) or FALSE (0) value.
The following table lists the comparison operators in the transformation language:
Greater than or equal to.
Use the greater than (>) and less than (<) operators to compare numeric values or return a range of rows based on the sort order for a primary key in a particular port.
When you use comparison operators in an expression, the operands must be the same datatype. For example, the expression 123.4 > ‘123’ is not valid because the expression compares a decimal with a string. The expressions 123.4 > 123 and ‘a’ != ‘b’ are valid because the operands are the same datatype.
If you compare a value to a null value, the result is NULL.
If a filter condition evaluates to NULL, the Integration Service returns NULL.
