1. Declare cursor first - It will select all the record
available in the filed 'ADMIN'
c/exec sql
c+ declare cr1 cursor for
c+ select ADMIN from EMPLOYEE
c/end-exec
2. Open the cursor - its like seting the pointer on the
first record
c/exec sql
c+ open cr1
c/end-exec
3. Fetch the cursor - its like reading the records in the
cursor. NAME is the field defined in the program which
attributs are same as per field ADMIN.
c/exec sql
c+ fetch cr1 into :name
c/end-exec
This code u can execute in Do loop to read all the records.
The complete coding would look like this
c/exec sql
c+ fetch cr1 into :name
c/end-exec
C dow sqlcod <>100
C
C name dsply
c/exec sql
c+ fetch cr1 into :name
c/end-exec
C enddo
