sql - HSTMT、UCHAR、SDWORD在ODBC日志中的含义

Question

我的 ODBC 日志中有以下行:

(场景:pgAdmin4，在另一个名为 System Administration 的应用程序中通过 ODBC32 使用 PostgreSQL 服务器)

System Admi 6a0-6f8 ENTER SQLExecDirect 
        HSTMT               0x00630718
        UCHAR *             0x036B29C0 [      63] "create table new (npages integer, ifnds integer, ifnid integer)"
        SDWORD                    63

我需要知道HSTMT、UCHAR* 和SDWORD 的含义。旁边的数字是什么意思？

来自文章Everything You Want To Know About ODBC Tracing

In the trace log, you’ll see the data type of the handle being SQLHANDLE, HENV / SQLHENV, HDBC / SQLHDBC, HSTMT / SQLHSTMT. This value is unique to the particular series of items being called. You can search in the trace log for this handle number and each call made on the handle will be shown. This allows you to pick out only the calls in the trace log that are relevant to your error message. Keep in mind, some applications may create multiple handles. For example, your application may execute three statements consecutively with each residing on a different statement handle.
