参数

• lOutputID
  The ID of the IDTSOutputColumn90 object.

• lOutputColumnID
  The ID of the IDTSOutputColumn90 object.

• eDataType
  The DataType to assign to the column.

• lLength
  The length of the column.

• lPrecision
  The total number of digits in the column.

• lScale
  The number of decimal places (digits to the right of the decimal point) allowed in the column.

• lCodePage
  The character set of the output column.

备注

The data type properties of an output column are dependent on each other and require that specific rules be followed based on the DataType of the column. This method enables a component to enforce these rules by setting all of the properties at once.

The following table lists the rules that apply 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 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
