I have a simple SQL query: SELECT * FROM test_table__csv_import_temp_joblist WHERE url ='https://www.example.com'

In phpMyAdmin, it works well and returns a result. In WP it returns nothing:

$sql        = "SELECT * FROM test_table__csv_import_temp_joblist WHERE url ='https://www.example.com'";
$res        = $wpdb->query( $sql );

What is the issue with my query?

$wpdb->last_query returns the right query. $wpdb->last_error returns nothing.

Many Thanks

Your problem is that you use query method of wpdb and if you read it’s docs:

The query function allows you to execute any SQL query on the WordPress database. It is best used when there is a need for specific, custom, or otherwise complex SQL queries. For more basic queries, such as selecting information from a table, see the other wpdb functions above such as get_results, get_var, get_row or get_col.

query  (string) The SQL query you wish to execute. This function returns an integer value indicating the number of rows affected/selected for SELECT, INSERT, DELETE, UPDATE, etc. For CREATE, ALTER, TRUNCATE and DROP SQL statements, (which affect whole tables instead of specific rows) this function returns TRUE on success. If a MySQL error is encountered, the function will return FALSE. Note that since both 0 and FALSE may be returned for row queries, you should be careful when checking the return value. Use the identity operator (===) to check for errors (e.g., false === $result), and whether any rows were affected (e.g., 0 === $result).

You’ll see that it’s not what you want.

If you want to get results of the query, you should use get_results method:

$res = $wpdb->get_results( $sql );
