Description
The GdaRepetitiveStatement object allows one to specify a statement to be executed several times using different variables' values sets for each execution. Using the object has almost no interrest at all if the statement to be executed several times has no parameter.
Use the gda_connection_repetitive_statement_execute() method to execute the repetitive statement.

GdaRepetitiveStatement *
gda_repetitive_statement_new (GdaStatement *stmt);
Creates a new GdaRepetitiveStatement object which, when executed, will execute stmt
once for all
the values set which will have been defined using gda_repetitive_statement_append_set().
Use gda_connection_repetitive_statement_execute() to actually execute it.
