IDTSOutputColumn90.SetDataTypeProperties Method

SQL Server 2005

Sets multiple data type properties of an IDTSOutputColumn90 object simultaneously.

Namespace: Microsoft.SqlServer.Dts.Pipeline.Wrapper
Assembly: Microsoft.SqlServer.DTSPipelineWrap (in microsoft.sqlserver.dtspipelinewrap.dll)

[DispIdAttribute(114)] 
void SetDataTypeProperties (
	[InAttribute] DataType eDataType,
	[InAttribute] int lLength,
	[InAttribute] int lPrecision,
	[InAttribute] int lScale,
	[InAttribute] int lCodePage
)
/** @attribute DispIdAttribute(114) */ 
void SetDataTypeProperties (
	/** @attribute InAttribute() */ DataType eDataType, 
	/** @attribute InAttribute() */ int lLength, 
	/** @attribute InAttribute() */ int lPrecision, 
	/** @attribute InAttribute() */ int lScale, 
	/** @attribute InAttribute() */ int lCodePage
)
DispIdAttribute(114) 
function SetDataTypeProperties (
	eDataType : DataType, 
	lLength : int, 
	lPrecision : int, 
	lScale : int, 
	lCodePage : int
)

Parameters

eDataType

The DataType of the column.

lLength

The length of the column.

lPrecision

The total number of digits of the output column.

lScale

The number of decimal places of the output column.

lCodePage

The character set of the output column.

The parameters of this method are individual read-only properties of the IDTSOutputColumn90 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 dependencies that are enforced when setting the data type properties of an output column.
