Start and end column positions (method L)

This radio button specifies that, for each table column, data is loaded according to start and end positions in the data file.

This radio button is selected and unavailable if the Nondelimited ASCII format (ASC) radio button on the File page is selected. Method L is the only method available for ASC files.

When this radio button is selected, the following fields are displayed in the Table column box:

Table column
Specifies the name of a column in the table that you are loading data into.

Include
Specifies whether data will be loaded into this table column. Possible values are Y (data will be loaded) or N (data will not be loaded).

Start position
Specifies the byte location in the load file of the beginning of the data column that you want loaded into the table column.

End position
Specifies the byte location in the load file of the end of the data column that you want loaded into the table column.

Null indicator
Specifies the data file column (by byte location) that contains the null indicator flag for the data being loaded into the table column. The default value is zero (0), specifying that the data column is not nullable (which means there will always be data to be loaded into this table column).

You can change the values of the Include, Start position, End position, and Null indicator fields by selecting a table column and clicking on Change. The Change window opens.
