Obtains an attribute from the last parse or extract function.
Category: | Data Quality |
Returned data type: | Character |
Note: | The returned value is a token value from the parse or extract function. Returns true if the token value is found or false if not. |
DQ.TOKENVALUE(<token string, output string>)
token string
returns true if the token is found and false if the token is not found
output string
a string that represents the value for that token
The DQ.TOKENVALUE function is used to retrieve an extraction or parse result value. The first parameter is the token name. It returns the attribute stored in that token in the second parameter. It returns true on success and false on failure (for example, if the token was not found). This function will follow a parse or extract function.
