推荐答案
您可能正在寻找只选择所需列的查询,如下所示:
You might just be looking for a query which selects only the columns you want, something like this:
$sql = "Select name as organization, status from $DB_TBLName";
而不是以下内容,它将选择所有列:
instead of the following, which selects all columns:
$sql = "Select * from $DB_TBLName";
请注意,我使用别名将name
列的名称更改为organization
.
Note that I used an alias to change the name of the name
column to organization
.
