SQL查询通过php脚本成功执行但不更新数据库

Question

就像标题所说，当通过php脚本执行我的查询时，它运行成功，但没有更新数据库。

直接在 SSMS 中执行查询，它可以 100% 工作并更新记录。它曾经可以工作，但今天它停止工作了，我不知道是什么导致了这个问题。

数据库中的所有列都是 VARCHAR 值。 下面是查询和 PHP 执行块

try {
    odbc_exec(CONNECTION, $SQL_ORDERS_INSERT);
    echo "LOCAL ORDERS ADDED<br><br>";
    odbc_free_result($ORDER_ADD);
catch (\Throwable $th) {
    echo $th->getMessage();
}

SQL 查询字符串已添加到变量

$SQL_ORDERS_INSERT

:

    INSERT INTO dbo.ORDERS (ORDER_NUMBER, TRANSACTION_TYPE, TRANSPORTER_CODE, SUPPLIER_CODE, SOURCE_CODE, CLIENT_CODE,

Answer 1

$SQL_ORDERS_INSERT 太长。 PHP 仅支持 256 个字符的字符串集。
