6. data SqlBool

   beam-core	Database.Beam.Query

   Phantom type representing a SQL Tri-state boolean -- true, false, and unknown This type has no values because it cannot be sent to or retrieved from the database directly. Use isTrue_, isFalse_, isNotTrue_, isNotFalse_, isUnknown_, isNotUnknown_, and unknownAs_ to retrieve the corresponding Bool value.

7. fromPossiblyNullBool_ :: QGenExpr context be s (Maybe Bool) -> QGenExpr context be s SqlBool

   beam-core	Database.Beam.Query

   Convert a possibly NULL Bool to a SqlBool.

8. possiblyNullBool_ :: QGenExpr context be s SqlBool -> QGenExpr context be s (Maybe Bool)

   beam-core	Database.Beam.Query

   Retrieve a SqlBool value as a potentially NULL Bool. This is useful if you want to get the value of a SQL boolean expression directly, without having to specify what to do on UNKNOWN. Note that both NULL and UNKNOWN will be returned as Nothing.

9. sqlBool_ :: QGenExpr context syntax s Bool -> QGenExpr context syntax s SqlBool

   beam-core	Database.Beam.Query

   Convert a known not null bool to a SqlBool. See unknownAs_ for the inverse

10. defaultBoolOptions :: BoolOptions

    cpphs	Language.Preprocessor.Cpphs

    Default settings of boolean options.
