1、查询目标库中的所有表

SELECT
obj.name tablename, ---表名
schem.name schemname,  ---表所属的方案
idx.rows,  ---一共有几行数组
CAST
(
    CASE WHEN (SELECT COUNT(1) FROM sys.indexes WHERE object_id= obj.OBJECT_ID AND is_primary_key=1) >=1 
    THEN 1
    ELSE 0
    END 
AS BIT
) 
HasPrimaryKey  ---表是否有主键
from ZC_UAC.sys.objects obj 
INNER JOIN
ZC_UAC.dbo.sysindexes idx ON obj.object_id=idx.id and idx.indid<=1 
INNER JOIN
ZC_UAC.sys.schemas schem ON obj.schema_id=schem.schema_id
where type in(\'U\')
order by obj.name

 

2、查询目标库中所有的表和视图

SELECT
obj.name tablename, ---表名
schem.name schemname,  ---表所属的方案
CAST
(
    CASE WHEN (SELECT COUNT(1) FROM sys.indexes WHERE object_id= obj.OBJECT_ID AND is_primary_key=1) >=1 
    THEN 1
    ELSE 0
    END 
AS BIT
) 
HasPrimaryKey  ---表是否有主键
from ZC_UAC.sys.objects obj 
INNER JOIN
ZC_UAC.sys.schemas schem ON obj.schema_id=schem.schema_id
where type in(\'U\',\'V\')
order by obj.name
