Lookup Component Error: Statement(s) Could Not Be Prepared.
Oct 8, 2007
Hi all,
I recieve an error when I use the Lookup component in SSIS that reads:
Statement(s) could not be prepared.
I'm using a SQL 2005 DB as the source which runs into a lookup table and is use to compare records with an SQL 2000 Database. I've created connection managers successfully to both these databases. When trying to use the results of an SQL Query for the lookup to the SQL 2000 database (which is a linked server) and I try to map the columns, the error pops up and exits out of the lookup properties Window
The details to the error read:
Program Location:
at Microsoft.SqlServer.Dts.Tasks.ExecuteSQLTask.Connections.SQLTaskConnectionOleDbClass.PrepareSQLStatement(String sql, Boolean bypassPrepare)
at Microsoft.DataTransformationServices.Design.DtsConnectionCommonControl.CheckSqlQuery()
I'm looking to use the results of this comparison to output in some form of a report. Ideas would be greatly appreciated!

Hello,
I am trying to get my mobilink aplication to synchronize with MS SQL Server 2000.
After getting rid of the global variable references I was using from ASA that the synchonization was failing on, it is now failing on the 8180 error.
I am not sure what it is not liking. I set the begin connection script to be blank as before it had "CREATE VARIABLE @UserID VARCHAR ( 128 )", as I found no easy way to delete the script sets with ISQL.
Microsoft says it has a hotfix for this particular error code, but I am not interested in calling their tech support line and paying to get it.
Any ideas?
The log from the Mobilink server says:

Hi,
I am getting this error in a Lookup component:
Error: 0xC020901E at Load_tblDelayfact, Lookup_DL_CODE [184]: Row yielded no match during lookup.
Error: 0xC0209029 at Load_tblDelayfact, Lookup_DL_CODE [184]: The "component "Lookup_DL_CODE" (184)" failed because error code 0xC020901E occurred, and the error row disposition on "output "Lookup Output" (186)" specifies failure on error. An error occurred on the specified object of the specified component.
Although the Lookup table is filled in with the following SELECT ststement:
SELECT DISTINCT DL_CODE, DL_COMMENT
FROM DL_Temp AS T1
WHERE NOT EXISTS(
SELECT * FROM DL_CODE AS T2
WHERE
T1.DL_CODE = T2.DL_CODE
AND
T1.DL_COMMENT = T2.DL_SENT_COMMENT
)
So there is no way that there is a record in DL_Temp (The data source) that does not exist in DL_CODE( the lookup table). Indded, I did serveral queries and tests to check that no such data exist and I found that no such record exists.
Please help me and tell me what can be the reason for this error. I used the same package on the same data yesterday and every thing went fine. Is that a bug that any of you faced before.
Thanks,
Aref

Hi,
Trying to get a particular SSIS is package working - while running the Package Installation wizard a package is reported with the following errors:
AcquireConnection method fails with error code 0xC0202009
Then Lookup fails validation and returns code 0xC020801C
The odd thing is the Lookup does not exist in the package, it did exist at one point but was deleted.
I have tried searching the XML and can't find any reference to the Lookup
Any suggestions appreciated...
Thanks,
John

Has anybody seen this issue already?
If you try to "enable memory restriction" from the Lookup component GUI you need to input both 32 and 64 bit size of maximum memory. However when clicking "OK" on the editor you get a message like :
TITLE: Microsoft Visual Studio
------------------------------
Error at Update Execution Logs [Lookup folder path 1 [4429]]: Failed to set property "MaxMemoryUsage64" on "component "Lookup folder path 1" (4429)".
------------------------------
ADDITIONAL INFORMATION:
Exception from HRESULT: 0xC0204006 (Microsoft.SqlServer.DTSPipelineWrap)
------------------------------
BUTTONS:
OK
------------------------------
You can only set the properties directly for mthe Properties window (F4).
I think this is a post SP1 bug in Visual studio designer...

Hi!
If I'm running a DTS with 2 connections(flat file source and SQL table destination) and a Data Driven Query Task, and then I get an error message saying "Stataments sould not be prepared. Line 2: Invalid syntax near "."
Which code should I look for the error? The message says Line 2 but i don't know where to look.

Hi,I'm running SQL Profiler on an SQL Server 2000 database. I see that onestored procedure gets repeatedly executed having a handle of '1'. Thisquery takes a long time to complete.How do I find what the text of the stored procedure is? I cant see anyhandle being created (using sp_prepare) with an id of '1' in theprofiler. Is there any way to force the server to re-prepare allstatements so that I can see the statement text and its preparation inSQL Profiler?Cheers,Birju

Hello,I have a table which contains some nullable columns. I want to write asingle query, which can be prepared (ie. prepared statement), that canhandle null or non-null values for the where clause. Is this possiblein a standard-conforming manner?The simple for of the query is this:SELECT * FROM <table> WHERE <column> = <value>But when the value to be matched on is NULL, the syntax of the querymust change to be:SELECT * FROM <table> WHERE <column> IS <value>In the second case <value> is NULL.I know one option might be to change the ANSI NULL handling option,but I am loathe to do this (I have five RDBMS's to support, not justMSSSQL).I thought I might have been able to cheat using an IN clause to makethe SQL consistent, but no luck.ThanksKevin

I have an application which uses ODBC to insert, update, delete records in an MSSQL DB. The application uses prepared statements and keeps the odbc statement handles to execute the same statement multiple times.
This application works fine until triggers are introduced. The triggers are pretty simple and take the inserted, updated record and insert this information into another table.
If we change the application to not re-use the prepared statement handle, by closing the statement handle after each execute, it also works fine. (However, this results in bad performance.)
The error message is: "[ODBC SQL Server Driver]Connection is busy with results for another hstmt". If anyone has any information on this, I would greatly appreciate the help!!!
Thank you.

Hello Folks,
I have a problem with a prepared statement against SS2005 SP2 that I do not fully understand. I have a query that is prepared and executed from a java application that looks similar to this:
SELECT TOP 1 str.ID FROM bigtable1 big1
LEFT OUTER JOIN bigtable2 big2
ON (big1.ID = big2.ID)
LEFT OUTER JOIN htable h ON (big2.HID = h.HID AND h.DIRECTSW=1)
WHERE big1.ID IN (SELECT ID FROM ltable WHERE LID IN(SELECT
LID FROM LAS WHERE LASID = ? )) AND big2.COMPLID <> 2 AND big2.COMPLID <> 3
AND ISNULL(big2.date1, big2.date2) BETWEEN ? AND ?
When run as a prepared statement this runs in about 27 seconds. When run under the query component of Management Studio it runs in about 1 second. Before each run I am clearing the buffers and the prepared statement cache. When running these I have looked at the execution plan from profiler and they both look the same. If I change the
WHERE big1.ID IN (SELECT ID FROM ltable WHERE LID IN(SELECT
LID FROM LAS WHERE LASID = ? ))
to INNER JOIN it runs ~1 second in both environments.
Any pointers would be welcome to explain the disrepency.
Thanks, Mark

Hi,
I am facing a problem while using pepared statement for inserting data in MS-Access db.
Code Snippet
private const String CONN_STR = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\Temp\TestDb.mdb";
conDatabase.Open(CONN_STR, "", "", -1);
String sQuery = "INSERT INTO " + sTableName +

cmdPrepStmnt.ActiveConnection = conDatabase;
cmdPrepStmnt.CommandText = sQuery;
cmdPrepStmnt.CommandType = CommandTypeEnum.adCmdText;
cmdPrepStmnt.Prepared = true;
int iCount = 0;
foreach (FileInfo f in fInfo)
{
Console.WriteLine("Adding File " + ++iCount + " of " + fInfo.Length + "; " + f.Name);
Parameter p1 = cmdPrepStmnt.CreateParameter("@FileName", ADODB.DataTypeEnum.adVarWChar, ParameterDirectionEnum.adParamInput, 255, f.FullName);
Parameter p3 = cmdPrepStmnt.CreateParameter("@IsCopied", ADODB.DataTypeEnum.adBoolean, ParameterDirectionEnum.adParamInput, 10, false);
Parameter p5 = cmdPrepStmnt.CreateParameter("@Size", ADODB.DataTypeEnum.adInteger, ParameterDirectionEnum.adParamInput, 10, f.Length);

cmdPrepStmnt.Parameters.Append(p5);
cmdPrepStmnt.Execute(out objAffected, ref obj, 0);
}
Code Snippet
FileName is coming as blank in db, while in debug mode i can see that it is being set with a proper filename. The other 2 params are inserting fine.
The FileName field is set as Text field with width length 255, and the incoming data is always shorter than 255 chars. The insertion happens without any errors/exceptions. I have also tried replacing the data for filename with a string like "Test", still it is inserting blank string.
Please help.

I have written a routine to search a unique record using prepared statement. Its my first sql coding with c++.
I am not using / importing any dlls.
I connect+allocs handels , then use SQLPrepare(StmtHandle, SQLStmt,SQL_NTS); to generate a guery.
I have written bind parameters and sqlexecute +sqlFetch in a loop and loop gets executed till ESC key is pressed.
First time when I bind paramaters using SQLBindParameter it works perfect.
When loop gets executed secondtime onwards, it gives an error.
SQLState: 24000 [ODBC Client Interface]Invalid cursor state.
If I open connection, handles, and prepared starement in same loop, THEN it gives correct record without 24000 error.
I want the advantage of prepared staement. So I do not want to close and open connection and prepare statement every time.
Have I missed any step?
Where & when I should code the cursor type? Any specific libraries I need to link?
Thanks

I need to use a modified SQL statement for a lookup component. It has an escape clause in it and this causes error:
select * from dbo.typecustomer where ? like '%'+type_subtype +'%'
ESCAPE '_'
Is this is a bug? Any help will be greatly appreciated.

Has anyone seen this strange behaviour?
I have a package which loads the fact data from Stage into Warehouse database. This packages normally handles early arriving facts. In that package I use lookup to check the dims which exists, and where they don't I populate the dimension and use the surrogate key to load the facts. This works fine.
I had a request to load 7 years worth of historical data. Instead of re-writing the package I took the package which handles early arriving facts and deleted the section which handles early arriving facts. I knew all the dimensions already exists and I don€™t want to hinder the performance when I load millions of rows. During testing I found something very interesting.
If you have configured error path in the lookup component and removed the error path later, the package will NOT fail (won't produce error) even if the lookup can't find matching values.
Correct Behaviour Example 1:
[1] Stage fact table has 2 records, with product code 1 and 2.
[2] Warehouse Product table has only product code 1.
[3] Source - Lookup - Destination in the data flow task. Error port on lookup is not configured.
[4] From source we read 2 records, and the package will fail at lookup as it can't find Product Code 2.
Correct Behaviour Example 2:
[1] Stage fact table has 2 records, with product code 1 and 2.
[2] Warehouse Product table has only product code 1.
[3] Source - Lookup - Destination in the data flow task. Error port on lookup is configured to go to RowCount.
[4] From source we read 2 records, and the package will run successfully. It will put one record into warehouse table and send the invalid record into RowCount.
Incorrect Behaviour Example 3:
[1] Stage fact table has 2 records, with product code 1 and 2.
[2] Warehouse Product table has only product code 1.
[3] Source - Lookup - Destination in the data flow task. Delete the configured error port from lookup.
[4] From source we read 2 records, and the package will run successfully. It will put one record into warehouse table and discard the other.
My understanding if the error port is NOT configured as shown in example 2, it should fail as shown in example 1.
Am I missing a point or is this suppose to be a correct behaviour or is it a bug?
Thanks

Hi,
i am doing a lookup to insert new records when the lookup has failed.
this works perfectly normally. however when my recordset has a name-column of type string with width 5 and my lookup-table has a name-column of char(20) the lookup will always fail and henc always inserting new records although the name "foo" should match.
is there a workaround for this, or do the compare-columns always have to be of the same type/length ?

Need to ask three questions regarding this component I am creating programatically:
1) How do you select "Modify the SQL statement" programatically.
2) How do you change the actual sql.
3) How do you add a parameter, also programatically.
I have manged to select "Enable memory restriction" by using
instance.SetComponentProperty("CacheType", 2);
but can't add a paramater and modify sql statement. Have used
instance.SetComponentProperty("SqlCommand", statement); and
instance.SetComponentProperty("SqlCommandParam", statement);
with no luck. Any ideas, have searched the web but found nothing.
Thanks.

Let's say I've a dimension with over 20 million rows. During my ETL, I need to replace the business keys with all the surrogate keys from this large dimension. The logic choice is to use the Lookup component. But does the Lookup component load all the 20 million rows into the memory? For a large dimension surrogate key lookup, what is the typical approach? TIA.

i am using a lookup component to do a typical SCD. Compare the Natural keys and if they are the same -- REdirect the rows and do whatever, If not present -- means the Error Rows -- redirect and do whatever.
WHen I use the component to do a Historical Load (which means -- there are no rows are in the Destination table) and put the Memory to Partial Cache -- the Data Flow STalls after about 46,000 rows, it just doesnt complete after that. But the moment I switch it to Full Cache -- it flows -- But Partial is what I am supposed to be using -- keeping in mind -- the Incremental Loads. Why does the component stall ?
I had used Partial Cache in an earlier project -- with a 18 Million Row Table --(albeit for incremental load) and it worked fine (though is was slow -- but tleast it worked) -- but now I am trying to load just 300,000 rows but it stalls.
I am using a 2GB RAM machine -- and set the Memory to 750 MB/500 MB nothing worked
I tried two different machines -- same thing happened.
Any insight will be appreciated.

Is it possible to reuse a Lookup component which is configured with Full chaching?
My requirement is as follows....
A input file have 2 columns called CurrentLocation and PreviousLocation. In the dataflow, values of these two columns needs to be replaced with values from a look up table called "Location".
In my package i have added two LookUp components which replaces values of CurrentLocation and PreviousLocation with the values available in the table "Location". Is there any way to reuse the cache of first lookup component for second column also?

Hi,
I am facing a problem with Lookup component in SSIS. I need to lookup from a transaction table for getting some info, But when im trying to implement the same, the Pre-Execute step itself got failed saying like,
€œ[DTS.Pipeline] Information: The buffer manager failed a memory allocation call for 524264 bytes, but was unable to swap out any buffers to relieve memory pressure. 9467 buffers were considered and 5956 were locked. Either not enough memory is available to the pipeline because not enough are installed, other processes were using it, or too many buffers are locked.
[Tracer [19717]] Error: A buffer could not be locked. The system is out of memory or the buffer manager has reached its quota.
[DTS.Pipeline] Error: component "Tracer" (19717) failed the pre-execute phase and returned error code 0xC020204B.€?
Component Tracer is the Look up. Tracer is having around 6.5 mil records. Is there any way to allocate more buffers thru buffer manager? Or is there any alternative to solve this problem? FYI, the hard disk free space is more than 250 GB.
Thanks in advance.

I'm working with an existing package that uses the fuzzy lookup transform. The package is currently working; however, I need to add some columns to the lookup columns from the reference table that is being used.
It seems that I am hitting a memory threshold of some sort, as when I add 3 or 4 columns, the package works, but when I add 5 columns, the fuzzy lookup transform fails pre-execute:
Pre-Execute
Taking a snapshot of the reference table
Taking a snapshot of the reference table
Building Fuzzy Match Index
component "Fuzzy Lookup Existing Member" (8351) failed the pre-execute phase and returned error code 0x8007007A.
These errors occur regardless of what columns I am attempting to add to the lookup list.
I have tried setting the MaxMemoryUsage custom property of the transform to 0, and to explicit values that should be much more than enough to hold the fuzzy match index (the reference table is only about 3000 rows, and the entire table is stored in less than 2MB of disk space.
Any ideas on what else could be causing this?

The aim is to eliminate error characters from within the firstname, lastname, address etc. fields by doing a lookup of an ASCII code reference table and making an InStr() type comparison.
I cannot find a way of opening the reference data set from withing the transform.
Regards
Tim

I am using a lookup component in a SSIS data flow. The lookup is a select to a foxpro table. THe lookup works fine with full cache selected. I cannot get the lookup to work with a partial or no cache. I have the latest Foxpro OLE DB driver installed which I understand to support paramaterized queries. Has anyone had success with using cached lookup to Foxpro? Does anyone know how to set the lookup properties of sqlcommand and sqlcommandparam? I am unable to find any examples in BOL or on the web.
Here are some details. IF I go with "use a table or a view" option with the default cache query I get initialization errors
[lkp_lab_worst_value [6170]] Error: An OLE DB error has occurred. Error code: 0x80040E14. An OLE DB record is available. Source: "Microsoft OLE DB Provider for Visual FoxPro" Hresult: 0x80040E14 Description: "Command contains unrecognized phrase/keyword.".
In the advanced editor I see
SQLCommand set to
"select * from `kcf`"
and SQLCommandParam set to
"select * from
(select * from `kcf`) as refTable
where [refTable].[patkey] = ? and [refTable].[dayof_stay] = ? and [refTable].[modifier] = ? and [refTable].[kcf_code] = ? and [refTable].[source] = ? and [refTable].[kcf_time] = ?"
I believe the above error is because Foxpro V7 does not support the inner subselect . In addition the query contains CRLF without a continuation character (";").
If I remove the CRLF in the sqlcommandparam query, using the advanced editor, I get this design time error "OLE D error occurred while loading column metadata. Check the sqlcommand and sqlcommandparam properties". The designer requires both properties to be set, its unclear to me how the interact.
I cannot find any examples in BOL or on the web on how to set these 2 properties. Can someone give me a few guidelines?
I can get past the design errors by changing sqlcommandparam to a plain select that is VFP 7 compatible ( I removed the subselect and the square brackets):
select * from kcf as refTable where refTable.patkey = ? and refTable.dayof_stay = ? and refTable.modifier = ? and refTable.kcf_code = ? and refTable.source = ? and refTable.kcf_time = ?
But then I get a runtime error
[lkp_lab_worst_value [6170]] Error: An OLE DB error has occurred. Error code: 0x80040E46. An OLE DB record is available. Source: "Microsoft OLE DB Provider for Visual FoxPro" Hresult: 0x80040E46 Description: "One or more accessor flags were invalid.".
[lkp_lab_worst_value [6170]] Error: OLE DB error occurred while binding parameters. Check SQLCommand and SqlCommandParam properties.
Any idea on what I should try next ?

I have an Excel file which contains some data. I want to load that into a SQL server Table. Here are my conditions :
1. If the table doesn't have any matching records from the Excel file, then my DFT should load the data from that Excel to the Dest Table.
2. If the table has even one or more matching records, then the DFT should not process at all, instead I should send an email to the business stating that there are some matching records and hence the package is not process...ed.
P.S. If i use Lookup, I have two matching and non-matching output. which will process the non matching records into the table and matching can be redirected to any flat/Excel file. But i don't want to do this. I just want to lookup the Sql Server table and excel.
It'll be good if there is an additional option in the Lookup "Fail component on matching records".

Hi there,
I'm trying to modify the SQL statement of a Lookup Transformation.
In my DataSet I have 2 columns A, B - I join against a table on columns A and B by
But I only want to match on column B - where column A doesn't match. (I'm looking for duplicate values of B)
So I've tried modifying the SQL statement to:
select * from
(select * from [dbo].[LookupTable]) as refTable
where [refTable].[ColumnB] = ? and [refTable].[ColumnA] <> ?
(The paremeter mapping takes care of itself).
Anyway, it seems sometimes I'm returning rows where it HAS matched on ColumnA.
I'm I on the right track here?
Cheers,
dave.

Hello All,
Below is a simple Select statement performing a Lookup into a SQL database and returning the columns (associated with the Row) in to Cells on an eForm. The issue I have is there are 42 rows (which go up and down) and do not feel like writing 42 select statements.
select RiskDescriptor, RiskImpactLowDescriptor, RiskImpactMediumDescriptor, RiskImpactHighDescriptor
from [Risk Descriptors]
where [RiskDescriptor ID] in (1)
order by [RiskDescriptor ID];
<<1@Cell104>>
<<2@Cell105>>
<<3@Cell106>>
<<4@Cell107>>
I would like to add a loop, adding 1 to the RiskDescriptor ID and 4 to the Cells. So on second pass in the loop:
RiskDescriptor ID = 2
<<1@Cell108>>
<<2@Cell109>>
<<3@Cell110>>
<<4@Cell111>>
Third pass in the loop:
RiskDescriptor ID = 3
<<1@Cell112>>
<<2@Cell113>>
<<3@Cell114>>
<<4@Cell115>>
and so on.
The Until portion of the loop can be hardcode (42 in this example) but would rather use an EOL or Query the DB for the total number of RiskDescriptor ID. This way when the DB changes (ID's go up or down) the SQL Statement does not need to be notified.
It is a JDBC call from within the eForm.
I would appreciate any help on how to format a loop in a SQL Statement

Hello,
I have a package that has a data lfow task. this task imports data from a db2 database (using the IBM Ole DB provider fro db2) and adds it to sql server database table. This package was created on the server. then though version control (using TFS source control) I check out the package on my local machine. and when I open the package I get the foll 3 errors.
Error 1 Validation error. Import Account Num from BMGP_BDR: DTS.Pipeline: The component metadata for "component "DataReader Source" (1113)" could not be upgraded to the newer version of the component. The PerformUpgrade method failed.
Error 2 Error loading BMAG Download Xref Tables - bmag.dtsx: Microsoft.SqlServer.Dts.Pipeline.ComponentVersionMismatchException: The version of component "DataReader Source" (1113) is not compatible with this version of the DataFlow. [[The version or pipeline version or both for the specified component is higher than the current version. This package was probably created on a new version of DTS or the component than is installed on the current PC.]] at Microsoft.SqlServer.Dts.Pipeline.ManagedComponentHost.HostCheckAndPerformUpgrade(IDTSManagedComponentWrapper90 wrapper, Int32 lPipelineVersion)

Hi,
I have a package which reads an Access file from a folder. My connection manager to this file is .NET providers for OledbMicrosoft Jet 4.0 OLE DB Provider.
Package works from my computer. But when I execute it on the server as a SQL Agent job, I get
The component metadata for "component "DataReader Source" (1) could not be upgraded to the newer version of the component. The PerformUpgrade method failed.
I copied the mdb file to a folder on the server which my packages have no problem reading data from.
My packages run under the same domain account as defined in proxies.
Appreciate a help.

I am using the lookup transform with the following settings:
Reference table: Use results of an SQL query. The query retrieves the surrogate key and four business key columns from a dimension table which contains a few thousand rows.
Columns: business keys in the incoming data are mapped to the business keys in the reference table, and the surrogate key is looked up from the reference table.
Advanced: Enable memory restriction is OFF (and the other items on the Advanced tab are greyed out).
I assumed that this means that the lookup transform would cache all of the rows in the SQL query, and then perform the lookups against this cache. This is the behaviour that I saw when I was running the package in my local environment in the BIDS debugger.
However, a colleague was doing some profiling on our production database server, and noticed that the lookup transform is instead issuing a single SQL query for each row of input. Our production ETL server has many GBs of free RAM available (way more than enough to cache the contents of the lookup table in memory), and given that memory restriction is disabled, I don't understand why the lookup transform is behaving in this fashion. Does anyone have an explanation for this? I'm probably misunderstanding a key concept here.
Thanks,
Greg
