SQL BIND

SQL BIND links a Q parameter to a table column. The SQL
commands FETCH, UPDATE, and INSERT evaluate this binding
(assignment) during data transfer between the result set and the
NC program.
An SQL BIND command without a table name or column name
cancels the binding. At the latest, the binding is terminated at the end
of the NC program or subprogram.
Programming notes:
Program any number of bindings with SQL BIND...,
before using the FETCH, UPDATE, or INSERT
commands.
During the read and write operations, the control
considers only those columns that you have specified
by means of the SELECT command. If you specify
columns without a binding in the SELECT command,
then the control interrupts the read or write operation
with an error message.
Parameter no. for result: Define Q parameter for
binding to the table column
Database: column name: Define table name and
table column (separate with . )
