(这个答案随着 OP 提供了更多代码而演变.这是最终的简化答案！)

wordpress dbDelta 函数会分解它在 ';' 上给出的字符串，该字符串位于您的 JSON 中.您需要做的是将您的查询分成一个数组，然后将其传递给 dbDelta.

The wordpress dbDelta function explodes the string it is given on ';', which is inside your JSON. What you need to do is separate your queries into an array, and pass that to dbDelta instead.

$sql1=array();
$sql1[]="insert into....";
$sql1[]="insert into....";

dbDelta($sql1);
