使分页与 mssql 一起使用的问题

Question

我试图设置此分页 table，但由于某种原因，我现在收到此错误，它正在使用 MySQL，但当我将其切换到 MSSQL 时。我收到此错误：

Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[42000]: [Microsoft][SQL Server Native Client 11.0][SQL Server]Incorrect syntax near '`'.' in C:\inetpub\wwwroot\pagination\index.php:40 Stack trace:#0 C:\inetpub\wwwroot\pagination\index.php(40): PDOStatement->execute()#1 {main}thrown in C:\inetpub\wwwroot\pagination\index.php on line 40 Line 40 is near the Stmt2 execute.

Answer 1

我怀疑错误的原因是 mysql 用来引用属性名称的 ` 个字符。 MSSQL 使用 [ 和 ].

只需删除 ` 字符，只要不使用保留字作为 table 属性，它们就不是必需的。

编辑： 至于 LIMIT 问题：您可以使用 doctrine DBAL 库，一个简单的 PDO 包装器。核心语法与 PDO 语法相同，但你有像查询构建器这样的好特性： http://doctrine-dbal.readthedocs.org/en/latest/reference/query-builder.html

通过查询生成器，您可以使用 ->setFirstResult() 和 ->setMaxResults() 来模拟 mysql.

中的限制函数

但是如果您使用 SQL Server 2012+，@AaronBertrand 在上面的评论中写的内容（使用 OFFSET / FETCH）会容易得多。
