The td.debug.enable is a boolean option which enables the user to understand and debug the steps happening while a call is made.
The default value is FALSE.
Example
This example shows the system output when this option is set to TRUE.
- Set the option to TRUE.
> options(td.debug.enable = TRUE)
- Create tbl_teradata of the table 'computers_train1'. The system lists the steps while this call is made.
> computers_train1 <- tbl(con, "computers_train1") In db_query_fields.Teradata(src$con, from): db_query_fields(src$con, from): vars %||% db_query_fields(src$con, from): tbl_sql(c('teradata', 'dbi'), src = src, from = from, ...): tbl.src_Teradata(src_teradata(src), from, ...): tbl(src_teradata(src), from, ...): tbl.Teradata(con, 'computers_train1'): tbl(con, 'computers_train1'): [tdplyr - (TDR_E1001)] Ignoring query: [tdplyr - (TDR_E1001)] Describe Columns given query/table/view: computers_train1 >
In contrary, if this option is set to default value of FALSE, system runs the call without showing the steps.
- Set the options to FALSE.
> options(td.debug.enable = FALSE)
- Create tbl_teradata of the table 'computers_train1'. The system runs the call without showing the steps.
> computers_train1 <- tbl(con, "computers_train1") >
