COLUMN_NAME_EX

Represents a binding on the rowset to the specific column in the rowset. Similar to COLUMN_NAME, except that this macro also takes data type, size, precision, scale, column length, and column status.

COLUMN_NAME_EX(pszName, wType, nLength, nPrecision, nScale, data, length, status )

Parameters

• pszName
  [in] A pointer to the column name. The name must be a Unicode string. You can accomplish this by putting an 'L' in front of the name, for example: L"MyColumn".

• wType
  [in] The data type.

• nLength
  [in] The data size in bytes.

• nPrecision
  [in] The maximum precision to use when getting data and wType is DBTYPE_NUMERIC. Otherwise, this parameter is ignored.

• nScale
  [in] The scale to use when getting data and wType is DBTYPE_NUMERIC or DBTYPE_DECIMAL.

• data
  [in] The corresponding data member in the user record.

• length
  [in] The variable to be bound to the column length.

• status
