Are you using the same statement object ? if so, it cannot work. Do you use OCI_Commit() ? If not, nothing will be committed !

Question
I'm trying to execute 2 queries (SELECT AND UPDATE). Select works, but update doesn't make any changes. What am I doing wrong?
Here some code:
OCI_Statement* st;
OCI_Resultset* rs;
query[0] ='\0';
//cn is connection
st = OCI_StatementCreate(cn);
sprintf (query, "SELECT ..");
printf (query);
OCI_ExecuteStmt(st, query);
rs = OCI_GetResultset(st);
//this works
while (OCI_FetchNext(rs)){
}
query[0] ='\0';
//query is correct; it does updates in the console
sprintf(query, "update vqc set vqc_u = 'J' where vqc_id >= 1 and vqc_id <= 12" );
//fails
//neither
OCI_ExecuteStmt(st, query);
//nor
OCI_Prepare(st, query);
OCI_Execute(st);
printf (query);
La solution
