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.

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
