Question

我正在创建一个智能列表，以便更好地查看报告。

我的问题是，当我在下面生成查询时，它会失败并出现此错误消息＆＃34;转换varchar值时转换失败＆＃39; Field2＆＃39;到数据类型int。＆＃34;

这是我的查询

SELECT * FROM (SELECT *, ROW_NUMBER() OVER (ORDER BY [SECCODE]) AS RowNumber 
FROM myDB.mySchema.myView 
WHERE [Field1]<[Field2]) tempTable WHERE [tempTable].[RowNumber]>=1 AND [tempTable].[RowNumber]<=100

Field2来自文本框。我尝试输入确切的字段名称但我仍然得到错误。

请帮忙。提前谢谢。

Answer 1

declare @v1 varchar(20);

select cast(@v1 as int)..


SELECT * FROM (SELECT *, ROW_NUMBER() OVER (ORDER BY [SECCODE]) AS RowNumber 
FROM myDB.mySchema.myView 
WHERE [Field1]<cast([Field2] as int) tempTable WHERE [tempTable].[RowNumber]>=1 AND [tempTable].[RowNumber]<=100

Answer 2

您是否尝试过使用cast或convert？

cast(varcharColumn as Int)或CONVERT(INT, varcharColumn)

将varchar值'[field]'转换为数据类型int时转换失败
