Help regarding passing parameters in SQL and Lookup

Hi,

1) I am using exceute SQL tasks in my control flow. 3 variables have been defined at the package level.They are mapped to 3 parameters respectively in the Execute SQL task.

When I try using these parameters in SQL error is thrown.Query is not getting parsed.My connection is OLEDB. Target and source are in SQL Server.

Can anyone suggest a workaround?

2) Before loading my target I need to define a Lookup . My requirement is if say consumer key matches in fact table then update it else insert.

2 kinds of lookup are available in SSIS dataflow tools. Simple Lookup for exact matching and Fuzzy Lookup for matching based on probability.

Neither of it supports my requirement? Can i put a select and insert query directly in Lookup or will need to call it from a file as a stored procedure?

Please suggest a solution for this too.

Thanks in advance.

Aman Anand

It'd be alot easier to work out what's going on if you told us:

The full error message|||

Jamie,

Thanks for your reply. My query is mentioned below:

INSERT INTO AUD_PROCESS_CONTROL
(LOAD_ID, MASTER_SEQ_ID, PROCESS_START_TIME, PROCESS_END_TIME, SOURCE_RECORD_COUNT, LOAD_RECORD_COUNT,
UPDATE_RECORD_COUNT, FAIL_RECORD_COUNT, EXTRACT_FROM_DATE_TIME, EXTRACT_TILL_DATE_TIME, LOAD_CONTROL_STATUS)
VALUES (1, ?, GETDATE(), GETDATE(), ?, ?, 0, 0, GETDATE(), GETDATE(), 'LR')

Audit table is being maintained to keep track of ETL parameters.

MASTER_SEQ_ID

SOURCE_RECORD_COUNT and

LOAD_RECORD_COUNT

are the 3 variables defined as int32 and the scope is at package level.

They are mapped to 3 parameters which are also defined with datatype as int.

error is something like it says unable to parse the parameters in the query!

will look at the links mentioned in your reply.

thanks again.

Aman

I meant to copy and paste the error message!

But regardless, you should be able to achieve this using an expression. The links I provided earlier will help.

Jamie,

Sorry for not copy pasting the error before here goes the entire stuff.

INSERT INTO AUD_PROCESS_CONTROL
(LOAD_ID, MASTER_SEQ_ID, PROCESS_START_TIME, PROCESS_END_TIME, SOURCE_RECORD_COUNT, LOAD_RECORD_COUNT,
UPDATE_RECORD_COUNT, FAIL_RECORD_COUNT, EXTRACT_FROM_DATE_TIME, EXTRACT_TILL_DATE_TIME, LOAD_CONTROL_STATUS)
VALUES (1, @.P_MASTER_SEQ_ID, GETDATE(), GETDATE(), @.P_SOURCE_RECORD_COUNT, @.P_LOAD_RECORD_COUNT, 0, 0, GETDATE(), GETDATE(), 'LR')

Error:

TITLE: SQL Task

The query failed to parse. Must declare the scalar variable "@.P_MASTER_SEQ_ID".

Variables have been defined as int64 and while mapping them to parameters datatype has been given as Long.

Aman

Again, try using an expression.

Sometimes it works even though the parser says opposite

Another solution is to build the complete query in a varaible

Turn Evaluate as an expression to True and build it like

"SELECT Dato, Kurs from [" + @.[User::Kurstype] + "$] WHERE (NOT (Kurs IS NULL))"

Hi,

Thanks for your invaluable replies jamie and cgpl.

I tried another workaround for my problem. Used ADO.NET connection manager for the query which was posing problems and passed the parameters as @.P_......,

Now this issue has been sorted.

Thanks again.

Aman
