我有一个varchar(1000)列声明为包含所有数字的字段,如下所示。我想执行以下脚本。我需要这个工作
Declare @PostalCode varchar(1000)=0 set @PostalCode ='7005036,7004168,7002314,7001188,6998955' Select hl.* From CountryLocation cl INNER JOIN refPostalCodes pc ON pc.PostalCode = hl.PostalCode where pc.Postalcode in (@PostalCode) and pc.notDeleted = 1
看来您想使用sp_executesql:
Declare @PostalCode varchar(1000)=0 set @PostalCode ='7005036,7004168,7002314,7001188,6998955' declare @sql nvarchar(4000) //didn't count the chars... select @sql = N'Select hl.* From CountryLocation cl INNER JOIN refPostalCodes pc ON pc.PostalCode = hl.PostalCode where pc.Postalcode in (' + @PostalCode + ') and pc.notDeleted = 1' exec sp_executesql @sql
以这种方式编码时,您需要 非常注意 SQL注入。
