The set statement is used to write a specified value into all the cells in any given column, or to copy values from one column to another.






If the keyword word to is used then column ColName will be updated using the constant value specified in Value.

If the word as is used then the values in the column SrcColName will be copied into column ColName.

If = is used then the expression is evaluated and the column values are set to the result. For a complete list of functions that can be used in an expression please refer to the list of functions in the article about the if statement

The ColName argument must identify an existing column. The modified column will be in the default DSET unless it is a fully qualified column name.

If the overwrite option is disabled, then only cells with blank values will be updated with the new value.


Set the column called Flag in the default DSET to a value of 0:

set Flag to 0

Set the column called Flag to be the value in the column status:

set Flag as status

Set the column called DiskTier to the 4th character in the existing value of that column

set DiskTier = @SUBSTR([DiskTier],4,1)

Set the column called Flag in the DSET custom.dataset to a value of Pending:

set custom.dataset.Flag to Pending

Set the column Flag to free if the rate column contains a value of 0:

where ([rate] == 0) {
    set Flag to free

Fill any blank values in the column username in the DSET Azure.usage to Unknown :

option overwrite = no
set Azure.usage.username to Unknown
