Void Initialization

Data type VOID initialization can only be applied to scalars. Creating a vector of VOID type is not supported.

x=NULL;
typestr x;
// output
VOID

take(NULL, 4);
// output
Not allowed to create void vector

Adding a NULL column to a table is not supported.

t = table(rand(10,10) as x)
addColumn(t, `col1, VOID)
// output
Invalid data type: 0
t[`col1]=NULL
// output
Not allowed to create void vector

You can use select with NULL to generate a table with VOID column.

tmp=select *, NULL from t
typestr(tmp[`NULL])
VOID VECTOR
