List of desired output columns, in desired order
Note that the final output will be the intersection of all enabled features and all columns in the list. Therefore, only columns associated with enabled features will actually appear in the output.
Likewise, removing columns from this list may effectively disable features, even if they are turned on
Each element in this list must be one of the valid output column names. Names must be delimited by square brackets. White space, formatting, and additional characters are allowed, as long as the list
contains exact matches of delimited valid column names.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value | [dd%][session_id][sql_text][sql_command][login_name][wait_info][tasks][tran_log%][cpu%][temp%][block%][reads%][writes%][context%][physical%][query_plan][locks][%] |

Valid column choices:
session_id, physical_io, reads, physical_reads, writes, tempdb_allocations,
tempdb_current, CPU, context_switches, used_memory, physical_io_delta,
reads_delta, physical_reads_delta, writes_delta, tempdb_allocations_delta,
tempdb_current_delta, CPU_delta, context_switches_delta, used_memory_delta,
tasks, tran_start_time, open_tran_count, blocking_session_id, blocked_session_count,
percent_complete, host_name, login_name, database_name, start_time, login_time
Note that column names in the list must be bracket-delimited. Commas and/or white space are not required.
| Alias | |

If set to a non-blank value, the script will attempt to insert into the specified destination table. Please note that the script will not verify that the table exists, or that it has the correct
schema, before doing the insert. Table can be specified in one, two, or three-part format
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value |
If set to 1, no data collection will happen and no result set will be returned; instead, a CREATE TABLE statement will be returned via the @schema parameter, which will match the schema of the result
set that would be returned by using the same collection of the rest of the parameters. The CREATE TABLE statement will have a placeholder token of <table_name> in place of an actual table name.

Specifies output type. Valid options for this parameter are 'DataSet', 'DataTable', 'DataRow', 'PSObject'. Default is 'DataRow'.

| Default Value | DataRow |
| Accepted Values | DataSet,DataTable,DataRow,PSObject |
By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value | False |
