Question

我正在sql server中编写一个sql脚本，它根据数据创建动态表。我最初收到错误“对象名称'GBIPS-I-DB324D.CoreReferenceStaging.dbo.FinData2000_1'包含的最大前缀数量。最大值为2”。在运行原始查询时。 GBIPS-I-DB324D是链接服务器对象。

我尝试使用execute语句，现在在关键字“USE”附近收到错误语法错误。

原始查询

BEGIN
    set nocount on

declare @startYear int, @startQuarter int, @sql nvarchar(max), @tableName varchar(50);
set @startYear = 2000;
set @startQuarter = 1;
while(@startYear < 2018)
    begin
        set @startQuarter = 1;

        while(@startQuarter < 5)
        begin
            set @tableName = 'FinData' + cast(@startYear as varchar) + '_' + cast(@startQuarter as varchar);
            set @sql = '
                drop table [GBIPS-I-DB324D].[CoreReferenceStaging].[dbo].[' + @tableName + ']; 
                create table [GBIPS-I-DB324D].[CoreReferenceStaging].[dbo].[' + @tableName + '] ( calendarYear int, calendarQuarter int, companyid bigint not null, dataitemid bigint not null, dataitemvalue numeric(28,6), fiscalyear int, fiscalquarter int, periodenddate datetime, filingdate datetime, latestforfinancialperiodflag bit, latestfilingforinstanceflag bit );
                insert into [GBIPS-I-DB324D].[CoreReferenceStaging].[dbo].[' + @tableName + ']
                    select fp.calendarYear, fp.calendarQuarter, fp.companyid, fd.dataitemid, fd.dataitemvalue, fp.fiscalyear, fp.fiscalquarter, fi.periodenddate, fi.filingdate, fi.latestforfinancialperiodflag, fi.latestfilingforinstanceflag
                    from [Xpressfeed_dev].[dbo].[ciqFinPeriod] fp
                    inner join [Xpressfeed_dev].[dbo].[ciqFinInstance] fi on fi.financialPeriodId = fp.financialPeriodId
                    inner join [Xpressfeed_dev].[dbo].[ciqFinInstanceToCollection] fc on fc.financialInstanceId = fi.financialInstanceId
                    inner join [Xpressfeed_dev].[dbo].[ciqFinCollection] c on c.financialCollectionId = fc.financialCollectionId
                    inner join [Xpressfeed_dev].[dbo].[ciqFinCollectionData] fd on fd.financialCollectionId = c.financialCollectionId
                    where YEAR(fi.periodenddate) = ' + cast(@startYear as varchar) + ' and QUARTER(fi.periodenddate) = ' + cast(@startQuarter as varchar)
            EXEC sp_executesql @sql

            set @startQuarter += 1
        end
        set @startYear += 1;
    end
end

修改后的查询

 BEGIN
    set nocount on

declare @startYear int, @startQuarter int, @sql nvarchar(max), @tableName varchar(50);
set @startYear = 2000;
set @startQuarter = 1;
while(@startYear < 2018)
    begin
        set @startQuarter = 1;

        while(@startQuarter < 5)
        begin
            set @tableName = 'FinData' + cast(@startYear as varchar) + '_' + cast(@startQuarter as varchar);
            set @sql = '
             EXECUTE (USE CoreReferenceStaging;drop table [dbo].[' + @tableName + ']) AT [GBIPS-I-DB324D]
             EXECUTE (USE CoreReferenceStaging;create table [dbo].[' + @tableName + '] ( calendarYear int, calendarQuarter int, companyid bigint not null, dataitemid bigint not null, dataitemvalue numeric(28,6), fiscalyear int, fiscalquarter int, periodenddate datetime, filingdate datetime, latestforfinancialperiodflag bit, latestfilingforinstanceflag bit )) AT [GBIPS-I-DB324D]

                insert into [GBIPS-I-DB324D].[CoreReferenceStaging].[dbo].[' + @tableName + ']
                    select fp.calendarYear, fp.calendarQuarter, fp.companyid, fd.dataitemid, fd.dataitemvalue, fp.fiscalyear, fp.fiscalquarter, fi.periodenddate, fi.filingdate, fi.latestforfinancialperiodflag, fi.latestfilingforinstanceflag
                    from [Xpressfeed_dev].[dbo].[ciqFinPeriod] fp
                    inner join [Xpressfeed_dev].[dbo].[ciqFinInstance] fi on fi.financialPeriodId = fp.financialPeriodId
                    inner join [Xpressfeed_dev].[dbo].[ciqFinInstanceToCollection] fc on fc.financialInstanceId = fi.financialInstanceId
                    inner join [Xpressfeed_dev].[dbo].[ciqFinCollection] c on c.financialCollectionId = fc.financialCollectionId
                    inner join [Xpressfeed_dev].[dbo].[ciqFinCollectionData] fd on fd.financialCollectionId = c.financialCollectionId
                    where YEAR(fi.periodenddate) = ' + cast(@startYear as varchar) + ' and QUARTER(fi.periodenddate) = ' + cast(@startQuarter as varchar)
            EXEC sp_executesql @sql

            set @startQuarter += 1
        end
        set @startYear += 1;
    end
end

据我所知，＆＃39; USE＆＃39;使用链接服务器时无法使用语句。这不能回答你关于2的最大值的问题但是＆＃39;使用＆＃39;不是要走的路。当游戏中没有链接服务器时，您可以使用＆＃39; USE＆＃39;，但在执行DML操作的同一语句中构建use-statement。您必须使用动态SQL来处理具有副作用的动态SQL

对象名称包含的前缀数量超过最大数量。运行链接查询时最大值为2
