The option(s) to resolve this Oracle error are: Rewrite your SELECT INTO statement so that only one row is returned. For example, if you tried to execute the following SQL statement: And there was more than one record in the suppliers table with the supplier_name of IBM, you would receive the ORA-01422 error message.In this case, it might be more prudent to create a cursor and retrieve each row if you are unsure of how many records you might retrieve.Almost all the functionality described here is common across all current Oracle Databases.However the documentation may describe some database features that are in specific Oracle Database versions, editions, or require additional database options or packs. There are more node-oracledb examples in the examples directory.When updating a Mysql table with identical values nothing's really affected so row Count will return 0. Perl below noted this is not always preferred behaviour and you can change it yourself since PHP 5.3.Just create your PDO object with fetch All()), which seems like a ridiculous waste of overhead and programming time. ON DUPLICATE KEY UPDATE statement is not an INSERT statement, row Count won't return the number or rows inserted or updated for such a statement.So what I need is a modified trigger that correctly handles multiple row inserts.
You can update one record, and you can delete one record.
The first parameter of the callback is an callback's error object will contain error information when the Promise chain fails.
If an invalid value is set for a property, then an error occurs.
That may not sound like too useful a thing now, but the MERGE statement represents a very powerful way to bring a database table into sync with an external source of data (such as a flat file feed from a remote system). The value for DEPTNO should be 50, DNAME should be “PROGRAMMING”, and LOC should be “BALTIMORE”.
The INSERT statement allows you to create new rows in database tables.
