Documentation
data DetailedQueryError Source
SQL query error. Reference: description of PQresultErrorField at http://www.postgresql.org/docs/devel/static/libpq-exec.html.
Constructors
| DetailedQueryError | |
Fields
| |
newtype QueryError Source
Simple SQL query error. Thrown when there is no PGresult object corresponding to query execution.
Constructors
| QueryError String |
Instances
newtype LibPQError Source
Internal error in libpq/libpqtypes library.
Constructors
| LibPQError String |
Instances
data ConversionError Source
Data conversion error. Since it's polymorphic in error type, it nicely reports arbitrarily nested conversion errors.
Constructors
| forall e . Exception e => ConversionError | |
Fields
| |
data ArrayItemError Source
Array item error. Polymorphic in error type
for the same reason as ConversionError.
Constructors
| forall e . Exception e => ArrayItemError | |
Fields
| |
Instances
data InvalidValue t Source
"Invalid value" error for various data types.
Constructors
| InvalidValue | |
Fields
| |
Instances
| Eq t => Eq (InvalidValue t) | |
| Ord t => Ord (InvalidValue t) | |
| Show t => Show (InvalidValue t) | |
| (Show t, Typeable * t) => Exception (InvalidValue t) | |
| Typeable (* -> *) InvalidValue |
data RangeError t Source
Range error for various data types.
Constructors
| RangeError | |
Instances
| Eq t => Eq (RangeError t) | |
| Ord t => Ord (RangeError t) | |
| Show t => Show (RangeError t) | |
| (Show t, Typeable * t) => Exception (RangeError t) | |
| Typeable (* -> *) RangeError |
data ArrayDimensionMismatch Source
Array dimenstion mismatch error.
Constructors
| ArrayDimensionMismatch | |
Fields
| |
data RowLengthMismatch Source
Row length mismatch error.
Constructors
| RowLengthMismatch | |
Fields
| |
data AffectedRowsMismatch Source
Affected/returned rows mismatch error.
Constructors
| AffectedRowsMismatch | |
Fields
| |
