This view contains confidential user information and should be accessed only by trusted data personnel with access to the restrictive user DBC password. For more information about the user DBC password, see Teradata® Vantage NewSQL Engine Security Administration, B035-1100.

The QryLogParamV view is populated if parameterized request logging is enabled with the PARAMINFO option for BEGIN/REPLACE QUERY LOGGING and this view (QryLogParamV)is included in a request.

For example:

SELECT QueryID, RowNum, ParamJSON from QryLogParam;

converts all the rows in DBQLParamTbl to JSON documents. The output is in CLOB format. To perform JSON operations on the data, use the QryLogParamJSON view instead.

For more information, see Teradata® Vantage SQL Data Definition Language Syntax and Examples, B035-1144.

ParamJSON

This column is generated by the TD_SYSFNLIB.TD_DBQLParam table operator function at runtime.
