为什么我不能在golang中使用多个参数我的sql查询有什么问题?
我有多个参数的问题,我不能用sql查询实现2个参数。我仍然得到错误,错误显示mssql:SequenceID附近的语法不正确。我的查询sql有什么问题,或者我的代码有什么问题为什么我不能在golang中使用多个参数我的sql查询有什么问题?,sql,database,go,Sql,Database,Go,我有多个参数的问题,我不能用sql查询实现2个参数。我仍然得到错误,错误显示mssql:SequenceID附近的语法不正确。我的查询sql有什么问题,或者我的代码有什么问题 package main import ( "database/sql" "fmt" _ "github.com/denisenkom/go-mssqldb" "github.com/gin-gonic/gin" "net/http" "time" ) func main

由于您的查询不包含任何占位符(
?
chars),因此QueryRow
不应该有其他arg。或许可以删除额外的参数:
db.QueryRow("select SequenceID, MobilePhone, Output, WillBeSentDate, SentDate, Status, DtmUpd from SMSblast2 where SequenceID IS NOT NULL AND MobilePhone IS NOT NULL").Scan[...]
1.永远不要通过连接字符串来建立查询。2.首先测试查询。3.阅读
QueryRow
的文档,思考MobilePhone在那里做什么。4.问一个人(这样效率更高)。谢谢你的建议。我试试看,但仍然会出现错误“mssql:靠近“?”的语法不正确。”
