het kan soms voorkomen dat de UDT’s van SAP corrupt raken. Om hiervan zeker te zijn, kunnen een aantal controle queries en ook “opruim queries” uitgevoerd worden:
/*1) UDT is defined but does not exist.*/
select TableName from OUTB
where not exists (
select 1 from sysobjects where xtype=’U’ and name=’@’+TableName
)
/*2) UDF is not registered.*/
select * from sysobjects where [name] like ‘@%’ and name not in
(select ‘@’+tablename from outb
union all
select ‘@’+logtable from outb where logtable is not null) and xtype=’U’
/*3) UDF is defined on an unregistered UDT.*/
select T0.TableID from CUFD T0 where left(T0.TableID,1)=’@’ and
not exists (select 1 from OUTB T1 where ‘@’ +T1.TableName =
T0.TableID or ‘@’+T1.LogTable= T0.TableID)
/*4) UDF is defined but does not exist.*/
select TableID, AliasID from CUFD where not exists (
select t0.name, t1.name
from sysobjects t0 inner join syscolumns t1
on t0.xtype=’U’ and t0.id=t1.id
where t0.name=TableID and t1.name=’U_’+AliasID)
and TableID not in (‘BTNT’, ‘OIBT’, ‘OSRI’, ‘SRNT’)
/*5) UDF valid values are defined for non-existing UDF.*/
select TableId, FieldID from UFD1 T
where not exists (
select 1 from CUFD where TableId=T.TableId and FieldID=T.FieldID
)
/*6) UDF definition does not match actuality.*/
select T1.UDF, T0.nvarchar_size as ‘act_size’, T1.nvarchar_size as ‘def_size’ from (
select T2.name + ‘.’ + T3.name as ‘UDF’, T3.length/2 as ‘nvarchar_size’ from sysobjects T2 inner join syscolumns T3 on T2.id=T3.id where T2.xtype=’U’ and T3.xtype in
(select xtype from systypes where name=’nvarchar’)
) T0
inner join (
select tableid + ‘.U_’ + aliasid as ‘UDF’, editsize as ‘nvarchar_size’
from cufd where typeid=’A’ and editsize>1
) T1
on T0.UDF=T1.UDF
where T0.nvarchar_size>T1.nvarchar_size
/*7a) UDF contains extra spaces in field TableID in User-fields description CUFD table.*/
select * from CUFD
where datalength(TableID)<>LEN(TableID)
and ascii(SUBSTRING (TableID, LEN(TableID)+1, 1)) =32
/*7b) UDF contains extra spaces in field AliasID in User-fields
description CUFD table*/
select * from CUFD
where datalength(AliasID)<>len(AliasID)
and ascii(SUBSTRING (AliasID, LEN(AliasID)+1, 1)) =32
/*8) UDF exists but is not defined*/
select T1.name, T0.name from sys.columns T0 join sys.objects T1 on T0.object_id = T1.object_id
left join CUFD T2 on T2.TableID = T1.name and (‘U_’ + T2.AliasID) = T0.name
where T1.type = ‘U’ and T0.name like ‘U/_%’ escape ‘/’
and (‘U_’ + T2.AliasID) is null
and (T0.name !=’U_NAME’ and T1.name not in (‘OUSR’, ‘AUSR’))
/*************************** Update Query with description: ***************************/
/*1)Below query will delete all users defined tables which are defined but not exist in SQL Server.*/
delete OUTB where ‘@’+TableName not in (
select name from sysobjects where xtype=’U’)
/* 2 ) We recommend to remove the tables displayed by the query from the database directly in the database interface. Please consider this solution according to your customization. */
/*3) Below query will delete all users defined fields which are defined on an unregistered UDT.*/

Just neediness to utter your article is as surprising. The clarity in your post is just outstanding and i can feign you’re an practiced on this subject. Fine with your permission allow me to grab your feed to keep positive to date with helpful post. Thankfulness a million and please have in stock resting on the enjoyable work.
