IDTSDesigntimeComponent100.SetOutputColumnDataTypeProperties Method
Sets the data type properties of an IDTSOutputColumn100 object.
Assembly: Microsoft.SqlServer.DTSPipelineWrap (in Microsoft.SqlServer.DTSPipelineWrap.dll)
void SetOutputColumnDataTypeProperties( int lOutputID, int lOutputColumnID, DataType eDataType, int lLength, int lPrecision, int lScale, int lCodePage )
Parameters
- lOutputID
- Type: System.Int32
The ID of the IDTSOutput100 object.
- lOutputColumnID
- Type: System.Int32
The ID of the IDTSOutputColumn100 object.
- eDataType
- Type: Microsoft.SqlServer.Dts.Runtime.Wrapper.DataType
The DataType of the column.
- lLength
- Type: System.Int32
The length of the column.
- lPrecision
- Type: System.Int32
The total number of digits in the column for numeric data types.
- lScale
- Type: System.Int32
The number of digits of precision in the column for numeric data types.
- lCodePage
- Type: System.Int32
The code page of the column.
The parameters of this method are properties of the IDTSOutputColumn100 object that are individually read-only, and must be set by using this method. This method is required because the values of these properties depend on each other. It provides a mechanism for updating these properties at the same time and enables the component and the data flow task to enforce the dependencies. The eDataType parameter dictates the requirements of the other parameter values.
The following table lists the rules that must be adhered to when setting the data type properties of an output column.
