Parameters for damex_describeValExp
| Parameter | Type | Description |
| INPUT | ||
| hValExp | long | The value expression handle. |
| OUTPUT | ||
| piType | xo_int | The type of the value expression: |
| piFuncType | xo_int | The type of the set function can be a bitwise OR of the following values: |
| phLeftValExp | long | The handle to the left value expression. This value is set only when the val expression type is one of the following: |
| phRightValExp | long | The handle to the right value expression. This value is set only when the value expression type is one of the following: |
| phVal | long | The handle to the value. This value is set only when the value expression type is SQL_VAL_EXP_VAL. Use damex_describeVal to get the details of the value. |
| phScalarValExp | long | The handle to the scalar value. This value is set only when the value expression type is SQL_VAL_EXP_SCALAR. Use damex_describeScalarValExp to get the details of the scalar method. Use damex_getFirstValExp and damex_getNextValExp to navigate the argument list returned by damex_describeScalarValExp. |
| RETURN | ||
