Question

在我的ColdFusion 11网站（使用SQL Server 2008 R2）中，以下cfquery引发了上述错误：

<cfquery name="deleteGrantModificationItems" datasource="#dsource#">
  DELETE col_key FROM myTable
  WHERE col_key = <cfqueryPARAM value = "#appkey#" CFSQLType = "CF_SQL_VARCHAR">
</cfquery>

当我运行sql profiler来捕获查询时，我得到：

Declare @p1 int
Set @p1=NULL
exec sp_prepexec @p1 output,N'@P1 varchar(8000)',N'DELETE col_key FROM myTable
WHERE col_key = @P1 ','000000001644'
select @p1

当我在查询分析器中运行上述内容时，出现以下错误：

Msg 208, Level 16, State 1, Line 1
Invalid object name 'col_key'.
Msg 8180, Level 16, State 1, Procedure sp_prepexec, Line 1
Statement(s) could not be prepared.

我一直无法找到错误原因。

您遇到语法错误，因为您应该使用DELETE FROM table_name ...，如：

<cfquery name="deleteGrantModificationItems" datasource="#dsource#">
  DELETE FROM myTable
  WHERE col_key = <cfqueryPARAM value = "#appkey#" CFSQLType = "CF_SQL_VARCHAR">
</cfquery>

DELETE doc：

[WITH [，... n]] DELETE

[TOP（表达）[PERCENT]]

[FROM]

[Macromedia] [SQLServer JDBC驱动程序] [SQLServer]无效的对象名称＆＃39; column_name＆＃39;
