Comparison Operators

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:

Operator	Meaning
=	Equal to.
>	Greater than.
<	Less than.
>=	Greater than or equal to.
<=	Less than or equal to.
<>	Not equal to.
!=	Not equal to.
^=	Not 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.
