VB.NET - 通过ODBC连接插入/删除

Question

我通过ODBC连接连接到AS/400。当我尝试从文件中插入和删除时，出现了古怪的错误。首先，我发现构造查询stirng格式是这样的：

"DELETE FROM <library>.<filename> WHERE <field> = <value>" 

因此，基于这一点，我写了这个：

"DELETE FROM RM#AVLIB.AV90909JWB WHERE MBR_NUM = " & mbr_num 

它扔约不顺心删除错误，奇怪的是，但我得到了它的消失，如果我完全去除库：

"DELETE FROM AV90909JWB WHERE MBR_NUM = " & mbr_num 

我猜它只是不喜欢的#符号，没有图书馆，因为我的默认librar工作y和我在这里使用的是一样的。但现在我得到我的INSERT一个错误，说：

ERROR [22003] [微聚焦] [RUMBA数据存取] [S1023934]数值超出范围。 SQLCODE = -420

经过我传递的所有值后，我没有看到任何比字段长度更长的值，所以我不确定这是从哪里来的。

这里是我的代码，因为它位于现在：

delQry = "DELETE FROM AV90301JWB WHERE MBR_CD = '" & MBR_CD & "' AND LOC_CD = '" & LOC_CD & "' AND PRP_ITM = '" & PRP_ITM & "'" 
pushQry = "INSERT INTO AV90301JWB (" & _

有谁看到我丢失的东西还是有关于如何找到我的问题的任何想法？

谢谢！

Answer 1

在标识符逸出无效字符或逃脱其冲突使用一个保留关键字是把它放在双引号标识符的标准ANSI SQL方式：

DELETE FROM "RM#AVLIB".AV90909JWB WHERE ... 

---

显然的值之一您正在插入或者您在where子句中使用的内容超出了为该列定义的范围。例如。如果列已定义为NUMERIC(2)，则不能插入100。

此外，我强烈建议你，而不是使用字符串连接命令参数：见https://*.com/a/2092851/880990
