代码的简单解释:
1、先通过SearchID获得表QueryUnit里面的TastID
Select @AccountId=account_id,@TastID=Tast_ID from QueryUnit Where Search_id = @SearchID;
2、然后根据TastID去找Unit表及UnitExt、Unit_Input表里的数据后并创建一个临时表##TemUnit
SELECT unit.Unit_ID ,Unit.TJCode,UnitCode,UnitName,pUnitName'+@FieldName+',Unit_Input.Input_ID
into ##TemUnit FROM Unit INNER JOIN
UnitExt ON Unit.Unit_ID = UnitExt.Unit_ID INNER JOIN
Unit_Input ON Unit.Unit_ID = Unit_Input.Unit_ID where Unit_Input.Tast_id='+@TastID+'');
用exec运行：
@FieldName等于
,unitExt.s1,unitExt.s2,unitExt.s3,unitExt.s4,unitExt.s5,unitExt.s6,unitExt.s7,
unitExt.s8,unitExt.s9,unitExt.s10,unitExt.s11,unitExt.s12,unitExt.s13,unitExt.s14,
unitExt.s15,unitExt.s16,unitExt.s17,unitExt.s18,unitExt.s19,unitExt.s20,
unitExt.s21,unitExt.s22'
------------------------------------------------------------------------
SELECT unit.Unit_ID ,Unit.TJCode,UnitCode,UnitName,pUnitName'+@FieldName+',Unit_Input.Input_ID
into ##TemUnit FROM Unit INNER JOIN
UnitExt ON Unit.Unit_ID = UnitExt.Unit_ID INNER JOIN
Unit_Input ON Unit.Unit_ID = Unit_Input.Unit_ID where Unit_Input.Tast_id='+@TastID+'');
3、根据SearchID来获得表QueryUnit中的Reporttype字段的数据。
select @Reporttype = ReportType from QueryUnit Where Search_id = @SearchID; --内外网
根据Reporttype字段来判断是外网还是内网中的数据。
如果Reporttype=1为内网数据表，否则为外网数据表。ReportName为表名
if(@Reporttype = 1)
Select @ReportName='ReportData_'+CAST(Report_id AS char(5)) from ReportTast where Tast_id=@TastID;
else
Select @ReportName='ReportOutData_'+CAST(Report_id AS char(5)) from ReportTast where Tast_id=@TastID;
4、同时根据TastID去找表 及Unit_Input的数据后并创建一个临时表##TemIndicatorData.
SELECT T1.input_id,T1.RowNo,T1.colNo,T1.DataValue into ##TemIndicatorData
FROM '+@ReportName+' T1 INNER JOIN
Unit_Input ON T1.Input_ID = Unit_Input.Input_ID
Where Tast_id='+@TastId+'
5、动态生成一组新的SQL字符串。

select
@s1 = @s1+',['
+rtrim(RowNo)+'_'+rtrim(colNo)+']=max(case when RowNo='
+rtrim(RowNo)+' and colNo='+rtrim(colNo)+' then DataValue end)'

select

from
##TemIndicatorData
where
RowNo>20 and RowNo<=30
group by

order by
RowNo,colNo;
---------------------------------------------------------------------------

set @s4 = '';
select

order by

set @s6 = '';
select
@s6 = @s6+',['
+rtrim(RowNo)+'_'+rtrim(colNo)+']=max(case when RowNo='

from
##TemIndicatorData
where
RowNo>50 and RowNo<=60
group by
RowNo,colNo
order by
RowNo,colNo;
----------------------------------------------------------------------------------
S7:
set @s7 = '';
select
@s7 = @s7+',['
+rtrim(RowNo)+'_'+rtrim(colNo)+']=max(case when RowNo='
+rtrim(RowNo)+' and colNo='+rtrim(colNo)+' then DataValue end)'
from
##TemIndicatorData
where
RowNo>60 and RowNo<=70
group by
RowNo,colNo
order by
RowNo,colNo;
--------------------------------------------------------------------------------------------
S8:
set @s8 = '';
select
@s8 = @s8+',['
+rtrim(RowNo)+'_'+rtrim(colNo)+']=max(case when RowNo='
+rtrim(RowNo)+' and colNo='+rtrim(colNo)+' then DataValue end)'
from
##TemIndicatorData
where
RowNo>70 and RowNo<=80
group by
RowNo,colNo
order by
RowNo,colNo;
---------------------------------------------------------------------------------------
S9:
set @s9 = '';
select
@s9 = @s9+',['
+rtrim(RowNo)+'_'+rtrim(colNo)+']=max(case when RowNo='
+rtrim(RowNo)+' and colNo='+rtrim(colNo)+' then DataValue end)'
from

group by

order by

-----------------------------------------------------------------------------------------
S10:
set @s1 = ' select input_id '+@s1;
set @s10 =@s10+' into ##TemIndicator from ##TemIndicatorData group by input_id order by input_id ';
------------------------------------------------------------------------------------------------------------------------
运行上面程序：
exec(@s1+@s2+@s3+@s4+@s5+@s6+@s7+@s8+@s9+@s10);
上面的程序运行时等同下面程序：（查询##TemIndicatorData表并临时创建一个临时表TemIndicator）
select input_id,[1_1]=max(case when RowNo=1 and colNo=1 then DataValue end),
[1_2]=max(case when RowNo=1 and colNo=2 then DataValue end),

exec(@AllSql+@Where);

--select @where;
代码的简单解释:
1、先通过SearchID获得表QueryUnit里面的TastID
Select @AccountId=account_id,@TastID=Tast_ID from QueryUnit Where Search_id = @SearchID;
2、然后根据TastID去找Unit表及UnitExt、Unit_Input表里的数据后并创建一个临时表##TemUnit
SELECT unit.Unit_ID ,Unit.TJCode,UnitCode,UnitName,pUnitName'+@FieldName+',Unit_Input.Input_ID
into ##TemUnit FROM Unit INNER JOIN
UnitExt ON Unit.Unit_ID = UnitExt.Unit_ID INNER JOIN
Unit_Input ON Unit.Unit_ID = Unit_Input.Unit_ID where Unit_Input.Tast_id='+@TastID+'');
用exec运行：
@FieldName等于
,unitExt.s1,unitExt.s2,unitExt.s3,unitExt.s4,unitExt.s5,unitExt.s6,unitExt.s7,
unitExt.s8,unitExt.s9,unitExt.s10,unitExt.s11,unitExt.s12,unitExt.s13,unitExt.s14,
unitExt.s15,unitExt.s16,unitExt.s17,unitExt.s18,unitExt.s19,unitExt.s20,
unitExt.s21,unitExt.s22'
------------------------------------------------------------------------
SELECT unit.Unit_ID ,Unit.TJCode,UnitCode,UnitName,pUnitName'+@FieldName+',Unit_Input.Input_ID
into ##TemUnit FROM Unit INNER JOIN
UnitExt ON Unit.Unit_ID = UnitExt.Unit_ID INNER JOIN
Unit_Input ON Unit.Unit_ID = Unit_Input.Unit_ID where Unit_Input.Tast_id='+@TastID+'');
3、根据SearchID来获得表QueryUnit中的Reporttype字段的数据。
select @Reporttype = ReportType from QueryUnit Where Search_id = @SearchID; --内外网
根据Reporttype字段来判断是外网还是内网中的数据。
如果Reporttype=1为内网数据表，否则为外网数据表。ReportName为表名
if(@Reporttype = 1)
Select @ReportName='ReportData_'+CAST(Report_id AS char(5)) from ReportTast where Tast_id=@TastID;
else
Select @ReportName='ReportOutData_'+CAST(Report_id AS char(5)) from ReportTast where Tast_id=@TastID;
4、同时根据TastID去找表 及Unit_Input的数据后并创建一个临时表##TemIndicatorData.
SELECT T1.input_id,T1.RowNo,T1.colNo,T1.DataValue into ##TemIndicatorData
FROM '+@ReportName+' T1 INNER JOIN
Unit_Input ON T1.Input_ID = Unit_Input.Input_ID
Where Tast_id='+@TastId+'
5、动态生成一组新的SQL字符串。
S1:
select
@s1 = @s1+',['
+rtrim(RowNo)+'_'+rtrim(colNo)+']=max(case when RowNo='
+rtrim(RowNo)+' and colNo='+rtrim(colNo)+' then DataValue end)'
from
##TemIndicatorData
where
RowNo<=10
group by
RowNo,colNo
order by
RowNo,colNo;
--------------------------------------------------------------------------
S2:
set @s2 = '';
select
@s2 = @s2+',['
+rtrim(RowNo)+'_'+rtrim(colNo)+']=max(case when RowNo='
+rtrim(RowNo)+' and colNo='+rtrim(colNo)+' then DataValue end)'
from
##TemIndicatorData
where
RowNo>10 and RowNo<=20
group by
RowNo,colNo
order by
RowNo,colNo;
--------------------------------------------------------------------------
S3:
set @s3 = '';
select
@s3 = @s3+',['
+rtrim(RowNo)+'_'+rtrim(colNo)+']=max(case when RowNo='
+rtrim(RowNo)+' and colNo='+rtrim(colNo)+' then DataValue end)'
from
##TemIndicatorData
where
RowNo>20 and RowNo<=30
group by
RowNo,colNo
order by
RowNo,colNo;
---------------------------------------------------------------------------
S4:
set @s4 = '';
select
@s4 = @s4+',['
+rtrim(RowNo)+'_'+rtrim(colNo)+']=max(case when RowNo='
+rtrim(RowNo)+' and colNo='+rtrim(colNo)+' then DataValue end)'
from
##TemIndicatorData
where
RowNo>30 and RowNo<=40
group by
RowNo,colNo
order by
RowNo,colNo;
-----------------------------------------------------------------------------
S5:
set @s5 = '';
select
@s5 = @s5+',['
+rtrim(RowNo)+'_'+rtrim(colNo)+']=max(case when RowNo='
+rtrim(RowNo)+' and colNo='+rtrim(colNo)+' then DataValue end)'
from
##TemIndicatorData
where
RowNo>40 and RowNo<=50
group by
RowNo,colNo
order by
RowNo,colNo;
---------------------------------------------------------------------------------
S6:
set @s6 = '';
select
@s6 = @s6+',['
+rtrim(RowNo)+'_'+rtrim(colNo)+']=max(case when RowNo='
+rtrim(RowNo)+' and colNo='+rtrim(colNo)+' then DataValue end)'
from
##TemIndicatorData
where
RowNo>50 and RowNo<=60
group by
RowNo,colNo
order by
RowNo,colNo;
----------------------------------------------------------------------------------
S7:
set @s7 = '';
select
@s7 = @s7+',['
+rtrim(RowNo)+'_'+rtrim(colNo)+']=max(case when RowNo='
+rtrim(RowNo)+' and colNo='+rtrim(colNo)+' then DataValue end)'
from
##TemIndicatorData
where
RowNo>60 and RowNo<=70
group by
RowNo,colNo
order by
RowNo,colNo;
--------------------------------------------------------------------------------------------
S8:
set @s8 = '';
select
@s8 = @s8+',['
+rtrim(RowNo)+'_'+rtrim(colNo)+']=max(case when RowNo='
+rtrim(RowNo)+' and colNo='+rtrim(colNo)+' then DataValue end)'
from
##TemIndicatorData
where
RowNo>70 and RowNo<=80
group by
RowNo,colNo
order by
RowNo,colNo;
---------------------------------------------------------------------------------------
S9:
set @s9 = '';
select
@s9 = @s9+',['
+rtrim(RowNo)+'_'+rtrim(colNo)+']=max(case when RowNo='
+rtrim(RowNo)+' and colNo='+rtrim(colNo)+' then DataValue end)'
from
##TemIndicatorData
where
RowNo>80 and RowNo<=90
group by
RowNo,colNo
order by
RowNo,colNo;
-----------------------------------------------------------------------------------------
S10:
set @s1 = ' select input_id '+@s1;
set @s10 =@s10+' into ##TemIndicator from ##TemIndicatorData group by input_id order by input_id ';
------------------------------------------------------------------------------------------------------------------------
运行上面程序：
exec(@s1+@s2+@s3+@s4+@s5+@s6+@s7+@s8+@s9+@s10);
上面的程序运行时等同下面程序：（查询##TemIndicatorData表并临时创建一个临时表TemIndicator）
select input_id,[1_1]=max(case when RowNo=1 and colNo=1 then DataValue end),
[1_2]=max(case when RowNo=1 and colNo=2 then DataValue end),
[2_1]=max(case when RowNo=2 and colNo=1 then DataValue end),
[2_2]=max(case when RowNo=2 and colNo=2 then DataValue end),
[11_1]=max(case when RowNo=11 and colNo=1 then DataValue end),
[11_2]=max(case when RowNo=11 and colNo=2 then DataValue end),
[12_1]=max(case when RowNo=12 and colNo=1 then DataValue end),
[12_2]=max(case when RowNo=12 and colNo=2 then DataValue end),
[21_1]=max(case when RowNo=21 and colNo=1 then DataValue end),
[21_2]=max(case when RowNo=21 and colNo=2 then DataValue end),
[22_1]=max(case when RowNo=22 and colNo=1 then DataValue end),
[22_2]=max(case when RowNo=22 and colNo=2 then DataValue end),
[31_1]=max(case when RowNo=31 and colNo=1 then DataValue end),
[31_2]=max(case when RowNo=31 and colNo=2 then DataValue end),
[32_1]=max(case when RowNo=32 and colNo=1 then DataValue end),
[32_2]=max(case when RowNo=32 and colNo=2 then DataValue end)
into ##TemIndicator
from ##TemIndicatorData group by input_id order by input_id
