Re: How to use SQL to select data by binary pattern

select * from myfile where land(lw9,x'0000001f')=x'00000013'

The LAND() scalar function performs a logical on the field. So with a bitmask of x'1f' (which is 11111 binary) the LAND will return only the rightmost 5 bits of the lw9 field. If those bits are set to x'00000013' (binary 10011) then you know the rightmost bits of the field are 10011.

If the DDS of myFile is as below:

A R RECDHDR
A LW9 4H

Is there a way to query this file where the last 5 bits of LW9 binary
pattern is = 10011?
