IDTSOutputColumn100.SetDataTypeProperties Method (DataType, Int32, Int32, Int32, Int32)
Applies To: SQL Server 2016 Preview
Sets multiple data type properties of an IDTSOutputColumn100 object simultaneously.
Namespace: Microsoft.SqlServer.Dts.Pipeline.Wrapper
Assembly: Microsoft.SqlServer.DTSPipelineWrap (in Microsoft.SqlServer.DTSPipelineWrap.dll)
Syntax
[DispIdAttribute(114)]
void SetDataTypeProperties(
DataType eDataType,
int lLength,
int lPrecision,
int lScale,
int lCodePage
)
[DispIdAttribute(114)]
void SetDataTypeProperties(
DataType eDataType,
int lLength,
int lPrecision,
int lScale,
int lCodePage
)
[<DispIdAttribute(114)>]
abstract SetDataTypeProperties :
eDataType:DataType *
lLength:int *
lPrecision:int *
lScale:int *
lCodePage:int -> unit
<DispIdAttribute(114)>
Sub SetDataTypeProperties (
eDataType As DataType,
lLength As Integer,
lPrecision As Integer,
lScale As Integer,
lCodePage As Integer
)
Parameters
eDataType
Type: Microsoft.SqlServer.Dts.Runtime.Wrapper.DataTypeThe DataType of the column.
lLength
Type: System.Int32The length of the column.
lPrecision
Type: System.Int32The total number of digits of the output column.
lScale
Type: System.Int32The number of decimal places of the output column.
lCodePage
Type: System.Int32The 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.
