我通常用PHP / MySQL编写代码但是这个项目必须使用MSSQL。
以下逻辑适用于MySQL,但因为在MSSQL设置中,限制是一个更复杂的查询,当我想追加查询时会导致问题。我已经玩弄了查询,试图弄清楚它应该如何,但无法使它工作。请帮忙。
//get all products for shopkeeper
if($limit == 0) {
$prod_qry = "SELECT id, productName FROM products WITH(NOLOCK) WHERE shopkeeper = '$this->shopkeeper'";
}
if($limit > 0) {
$prod_qry = "SELECT * FROM ( SELECT id, productName, ROW_NUMBER() OVER (ORDER BY id) as row FROM products WITH(NOLOCK) WHERE shopkeeper='$this->shopkeeper' ) a WHERE row > $start and row <= $limit";
}
if($hidden == 1) {
$prod_qry .= " AND Hidden !='1'";
}
if($rating != 0) {
$prod_qry .= " AND rating > '$rating'";
}
*的 修改 * 我想通了,修改了以下代码:
$prod_qry = "SELECT * FROM ( SELECT id, productName, ROW_NUMBER() OVER (ORDER BY id) as row FROM products WITH(NOLOCK) WHERE shopkeeper='$this->shopkeeper'" ;
if($hidden == 1) {
$prod_qry .= " AND Hidden !='1'";
}
if($rating != 0) {
$prod_qry .= " AND rating > '$rating'";
}
$prod_qry .= ") a ";
if($limit > 0) {
$prod_qry .= " WHERE row > $start and row <= $limit";
}
