Parameters

  • lPrecision
    Type: System.Int32
    The total number of digits in the column.
  • lScale
    Type: System.Int32
    The number of decimal places (digits to the right of the decimal point) allowed in the column.
  • lCodePage
    Type: System.Int32
    The character set of the output column.

Implements

IDTSDesigntimeComponent100.SetOutputColumnDataTypeProperties(Int32, Int32, DataType, Int32, Int32, Int32, Int32)

Remarks

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.
