SQL Syntax

The SQL syntax for a client function is:

{? = call client_function(?, ?,...)} 

Use the first parameter marker ("?") only when the first parameter is an output parameter.

The following code example invokes a client function when the first parameter is an output parameter:

{? = call ifx_lo_open(?, ?, ?)}

The following code example invokes a client function when the first parameter is not an output parameter:

{call ifx_lo_create(?, ?, ?, ?)}
