Question

I have string query in and pass @Date object to string. It is giving error. See below code.

Declare @MidDate datetime, @MaxDate datetime


set @qrysales_trans_unit_26wks ='update historical_result
    set sales_trans_unit_26wks = (      
            SELECT      
            SUM(sales_trans_unit)
            FROM reg_summary_rowno  WHERE  
            period_idx >= '+  @MidDate  // error 
            +' AND period_idx <'+  @MaxDate /error
            +' AND Client_id ='+ @Client_id
            +' and historical_result.[store_idx] = reg_summary_rowno.[store_idx]
            And [attributes] ='+  @attributes +')'

How to pass Datetime object in the proper way to string Query?

Answer 1

Try using two single quotes to escape quote marks so dates end up like: period_idx >= ‘@MidDate’

set @qrysales_trans_unit_26wks ='update historical_result
        set sales_trans_unit_26wks = (      
                SELECT      
                SUM(sales_trans_unit)
                FROM reg_summary_rowno  WHERE  
                period_idx >= '''+  @MidDate
                +''' AND period_idx <'''+  @MaxDate
                +''' AND Client_id ='+ @Client_id
                +' and historical_result.[store_idx] = reg_summary_rowno.[store_idx]
                And [attributes] ='+  @attributes +')'
