Hi,
1.
I am using C_API for accessing data from MYSQL.
2.
mysql_query() function returns the following values:
0 if the query is successful
-1 if the query fails.
3.
At the same time mysql-C_API documentation specifies
that it returns a non zero number if query is a
failure.Does the function return any other values
other than -1 if the query fails?
4.
If I use the mysql_query() for INSERT or UPDATE
statements I am facing the following problem:
If the database column value I am trying to update is
the same as the the value already existing in the
database,then the mysql_query() returns 0 and the
mysql_affected_rows() returns zero.
It will be good if mysql_query either returns -1 for
this case as the value being updated is same as that
of existing one.
Regards,
Ravi
