STRING function [String]

Concatenates one or more strings into one large string.

STRING( string-expression [, ... ])
  • string-expression   The string to be evaluated.

    If only one argument is supplied, it is converted into a single expression. If more than one argument is supplied, they are concatenated into a single string.


Numeric or date parameters are converted to strings before concatenation. The STRING function can also be used to convert any single expression to a string by supplying that expression as the only parameter.

If all parameters are NULL, STRING returns NULL. If any parameters are non-NULL, then any NULL parameters are treated as empty strings.
