adding wildcard to generated string

[dessure]

What would be the best way to add a wildcard '%' to the beginning and end of each generated SQL for a back-end based on TextQueryBackend ?

Example - now I generate this :

SELECT
  *,
  sigma AS sigma_pre_flux
FROM
(
SELECT
  *,
  map(
  'rule3',
      map(
      'cr_1', (CommandLine ILIKE 'svchost.exe -k netsvcs' OR CommandLine ILIKE 'taskeng.exe',
)
) AS sigma
FROM process_telemetry_view
)

And I need this:

SELECT
  *,
  sigma AS sigma_pre_flux
FROM
(
SELECT
  *,
  map(
  'rule3',
      map(
      'cr_1', (CommandLine ILIKE '%svchost.exe -k netsvcs%' OR CommandLine ILIKE '%taskeng.exe%',
)
) AS sigma
FROM process_telemetry_view
)

Thanks!!
