pdo_sqlsrv: how to recognize if fetch “false” is an error or empty recordset?

由 寵の児 提交于 2020-01-06 07:10:19
问题 The fetch method returns false both if the recordset is empty and if there is an actual error. The method described here allows you to easily recognize what is happening: ensure that PDO fetch method result "false" is a error or empty result It works well with pdo_mysql, however pdo_sqlsrv throws an error even when the recordset is empty. Is this the intended behaviour? Is it possible to avoid those errors? EDIT: the error is "There are no more rows in the active result set" and it is

问题 I've been scratching my head over this code for a couple of hours....

PDO binding fails with PostgreSQL window function parameters

由 微笑、不失礼 提交于 2020-01-06 06:11:22
问题 I have to perform a SELECT query on a PostgreSQL database usign the OVER() window function. It allows to get either the range of selected rows specified through the OFFSET and LIMIT values, or the number of total rows the query would get without the limit: SELECT DISTINCT *, COUNT(id) OVER() AS results_num FROM ( SELECT id, name, surname FROM users WHERE children > 1 ORDER BY id ) AS x OFFSET 0 ROWS FETCH NEXT 10 ROWS ONLY; To develop a paging method I need to set offset and limit dynamically

PDO and caching, how to implement it in a database class?

由 痴心易碎 提交于 2020-01-06 04:36:14
问题 When using PDO and MySQL, is there any benefit in caching results that I know I am going to be using multiple times on the same page? Or does PDO / MySQL automatically handle this sort of thing? And if I should do it myself, should I store the actual results from a query, or could I just store the PDOStatements in a cache and reuse them? Of course I could store any result I know I'm going to use multiple times on a page in a variable, but it just seems cleaner to let my database class handle
