I am giving this query to bot:

give me race from dm table where usubjid is 01_002199.

to form SQL query as:

Select race from dm where usubjid = ‘01_002199’

but its forming as: Select race from dm where usubjid = ‘2199’

My config file is like this:

pipeline:

  • name: WhitespaceTokenizer
  • name: RegexFeaturizer
  • name: RegexEntityExtractor
  • name: LexicalSyntacticFeaturizer
  • name: CountVectorsFeaturizer

  • name: RulePolicy
  • name: UnexpecTEDIntentPolicy max_history: 5 epochs: 100
  • name: TEDPolicy max_history: 5 epochs: 100 constrain_similarities: true

can someone help me why ‘01_00’ is ignored even though i have regex in place( \d{2}[-_*]\d{6}) which allows this value.
