eDataType
Tipo: Microsoft.SqlServer.Dts.Runtime.Wrapper. . :: . .DataType
The DataType of the column.

lLength
Tipo: System. . :: . .Int32
The length of the column.

lPrecision
Tipo: System. . :: . .Int32
The total number of digits in the column for numeric data types.

Comentários

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.

DataType	Length	Scale	Precision	CodePage
DT_DECIMAL	0	Greater than 0 and less than or equal to 28.	0	0
DT_CY	0	0	0	0
DT_NUMERIC	0	Greater than 0 and less than or equal to 28 and less than Precision.	Greater than or equal to 1 and less than or equal to 38.	0
DT_BYTES	Greater than 0.	0	0	0
DT_STR	Greater than 0 and less than 8000.	0	0	Not 0, and a valid code page.
DT_TEXT	Greater than 0 and less than 8000.	0	0	Not 0, and a valid code page.
DT_WSTR	Greater than 0 and less than 4000.	0	0	0
