f2s_esql_get_row

Applies to: Oracle, MS SQL, MySql/MariaDB, PostgreSQL Drivers

Syntax

f2s_esql_get_row {variant[]} [using {variant}]

Parameter

Description

Boolean variable

Optional Boolean variable to indicate the success or failure of the command

variant

Optional variant type variable that will receive a statement interface

Description

This command is used to fetch the current row returned by the associated SQL statement into a variant value.

The optional “using” syntax allows you to pass around the interface created by this command. The variable passed MUST be a variant. This allows for multiple statements to be active concurrently in some cases. If you use the “using” syntax, it must be used on all subsequent commands. Mixing the using syntax is not supported. So for instance, if you plan on having multiple statements active concurrently, all active statements must make use of the using syntax.

Note that the columns are fetched in the order that the SQL statement generates them, so the variables must follow the same order.

Error Codes

Error Message

25006

There is no active result set to advanced on for this statement.
