120 \enum QSql::NumericalPrecisionPolicy |
|
121 |
|
122 This enum type describes at which precision levels numercial values are read from |
|
123 a database. |
|
124 |
|
125 Some databases support numerical values with a precision that is not storable in a |
|
126 C++ basic data type. The default behavior is to bind these values as a QString. |
|
127 This enum can be used to override this behavior. |
|
128 |
|
129 \value LowPrecisionInt32 Force 32bit integer values. In case of floating point numbers, |
|
130 the fractional part is silently discarded. |
|
131 \value LowPrecisionInt64 Force 64bit integer values. In case of floating point numbers, |
|
132 the fractional part is silently discarded. |
|
133 \value LowPrecisionDouble Force \c double values. |
|
134 \value HighPrecision The default behavior - try to preserve maximum precision. |
|
135 |
|
136 Note: The actual behaviour if an overflow occurs is driver specific. The Oracle database |
|
137 just returns an error in this case. |
