Store array of bytes in a table column

Posted by RVR on September 11, 2024 at 3:29 pm

I have a table like t:([] k:symbol$(); v:byte$()). The size of column v is 1 here. As per the documentation this corresponds to JAVA Byte. How can we store a byte array Byte[]?

q does not have a type for lists of lists so you use the generic untyped list ()
```
q)tab:([] bytesCol:())
q)`tab insert enlist (0x0021;0x0002232)
0 1
q)tab
bytesCol
----------
0x0021
0x00002232
q)meta tab
c       | t f a
--------| -----
bytesCol| X
q)type tab`bytesCol
0h
```
