compileQuery :: DynamicSQLQuery -> (Query, [Action]) Source #
compileQueryWithRenamer :: Renamer -> DynamicSQLQuery -> (Query, [Action]) Source #
camelCaseRenamer :: Renamer Source #
Default renamer used by DataSync.
Transforms JS inputs in camelCase to snake_case for the database
and DB outputs in snake_case back to camelCase
unmodifiedRenamer :: Renamer Source #
Renamer that does not modify the column names
renameField :: Renamer -> Field -> Field Source #
When a Field is retrieved from the database, it's all in snake_case. This turns it into camelCase
compileQueryMapped :: DynamicSQLQuery -> (Query, [Action]) Source #
mapColumnNames :: (Text -> Text) -> DynamicSQLQuery -> DynamicSQLQuery Source #
Used to transform column names from camelCase to snake_case
compileSelectedColumns :: SelectedColumns -> Action Source #
compileCondition :: ConditionExpression -> (Query, [Action]) Source #
compileOperator :: ConditionOperator -> Query Source #
