IDTSOutputColumn100.SetDataTypeProperties(DataType, Int32, Int32, Int32, Int32) IDTSOutputColumn100.SetDataTypeProperties(DataType, Int32, Int32, Int32, Int32) IDTSOutputColumn100.SetDataTypeProperties(DataType, Int32, Int32, Int32, Int32) Method

Definition

Sets multiple data type properties of an IDTSOutputColumn100 object simultaneously.

public:
 void SetDataTypeProperties(Microsoft::SqlServer::Dts::Runtime::Wrapper::DataType eDataType, int lLength, int lPrecision, int lScale, int lCodePage);
[System.Runtime.InteropServices.DispId(114)]
public void SetDataTypeProperties (Microsoft.SqlServer.Dts.Runtime.Wrapper.DataType eDataType, int lLength, int lPrecision, int lScale, int lCodePage);
Public Sub SetDataTypeProperties (eDataType As DataType, lLength As Integer, lPrecision As Integer, lScale As Integer, lCodePage As Integer)
Parameters
eDataType
DataType DataType DataType

The DataType of the column.

lLength
Int32 Int32 Int32

The length of the column.

lPrecision
Int32 Int32 Int32

The total number of digits of the output column.

lScale
Int32 Int32 Int32

The number of decimal places of the output column.

lCodePage
Int32 Int32 Int32

The character set of the output column.

Remarks

The parameters of this method are individual read-only properties of the IDTSOutputColumn100 object whose values are set by using this method. The method is required because the values of these properties are dependent on each other. This method provides a mechanism for updating these properties atomically, allowing the data flow to enforce the dependencies. The eDataType parameter is used to determine the other checks to perform on the parameter values.

The following table shows the requirements that are enforced when setting the data type properties of an output column.

DataType Length Scale Precision CodePage
DT_DECIMAL Not enforced Greater than or equal to 0, and less than or equal to 28. Not enforced Not enforced
DT_NUMERIC Not enforced Greater than or equal to 0, and less than or equal to 38, and less than or equal to the specified precision. Greater than or equal to 1, and less than or equal to 38. Not enforced
DT_BYTES Greater than 0, and less than or equal to 8000. Not enforced Not enforced Not enforced
DT_DBTIME2

DT_DBTIMESTAMP2

DT_DBTIMESTAMPOFFSET
Not enforced. Greater than or equal to 0, and less than or equal to 7. Not enforced. Not enforced.
DT_STR Greater than 0 and less than or equal to 8000. Not enforced Not enforced Not 0.
DT_TEXT Not enforced Not enforced Not enforced Not 0.
DT_WSTR Greater than 0 and less than or equal to 4000. Not enforced Not enforced Not enforced
