Question

我正在尝试修改此查询，以便为数据库中的每个表提供行计数，其中表包含“Archive”列，总行数以及“Archive = 1”的行数。我已经完成了第一部分，但我的第二部分是大脑放屁。

SELECT sc.name +'.'+ ta.name TableName,SUM(pa.rows) RowCnt
 FROM sys.tables ta
 INNER JOIN sys.partitions pa ON pa.OBJECT_ID = ta.OBJECT_ID
 INNER JOIN sys.schemas sc ON ta.schema_id = sc.schema_id
 WHERE ta.is_ms_shipped = 0 AND pa.index_id IN (1,0)
 AND OBJECT_NAME(pa.object_id) IN 
 (
       --Criteria 1
   SELECT iq.TABLE_NAME
   FROM INFORMATION_SCHEMA.COLUMNS iq
   WHERE COLUMN_NAME LIKE '%Archive%'
 )
GROUP BY sc.name,ta.name
ORDER BY SUM(pa.rows) DESC

提前感谢您的任何帮助或建议。

这有点令人讨厌，但希望这会奏效：

create table #result 
(
    schemaName sysname, tableName sysname, recordCount bigint, archiveCount bigint, sqlCommand nvarchar(max)
)
alter table #result add primary key clustered (schemaName, tableName)

insert #result (schemaName, tableName, recordCount, archiveCount, sqlCommand)
SELECT sc.name, ta.name, 0, 0, 'update r set sqlCommand=null, recordCount=cnt, archiveCount=arch from #result r inner join 
(select ' + quotename(sc.name,'''') + ' schemaName, ' + quotename(ta.name,'''') + ' tableName, count(1) cnt, count(case' +
   (SELECT
        ' when ' + QUOTENAME(c2.name) + ' = 1 then 1' 
        FROM sys.columns c2
        WHERE c2.object_id = ta.object_id
        and c2.name like '%Archive%'
        and c2.system_type_id = 56 --int
        FOR XML PATH(''), TYPE
   ).value('.','varchar(max)')
   + ' else null end) arch from ' + QUOTENAME(sc.name) + '.' + QUOTENAME(ta.name) + ') x on x.schemaName=r.schemaName and x.tableName=r.tableName' 
FROM sys.tables ta
INNER JOIN sys.schemas sc 
    ON sc.schema_id = ta.schema_id
INNER JOIN sys.columns c
    ON c.object_id = ta.object_id
WHERE ta.is_ms_shipped = 0 
and c.name like '%Archive%'
and c.system_type_id = 56 --select name, system_type_id from sys.types where name='int'
GROUP BY sc.name,ta.object_id,ta.name

declare @sql nvarchar(max)
select @sql = sqlCommand from #result where sqlCommand is not null
while @sql is not null
begin
    print @sql
    exec(@sql)
    set @sql = null
    select @sql = sqlCommand from #result where sqlCommand is not null
end

select * from #result

数据库表行计数列值为True
