This is the more standardized method for concatenation in Teradata enterprise systems. As per the Teradata manual, this operator-based concatenation is the more preferred way of concatenation. As with CONCAT() function the concatenation operator is also used for the concatenation of two strings are numeric values. The symbol is used for concatenation. More than one concatenation inputs can be passed to these operators whereas the output of the concatenation function is always a single value returned. Teradata allows the capability of making the concatenation operation to happen not only by means of pipe operator but it can also be performed by means of the exclamatory operator !!. Even though an exclamatory operator can be used for this purpose it is not considered as a standardized symbol of concatenation as per Teradata manuals. We can discuss these different operators used for concatenation in Teradata systems in the below-listed examples.
