SQL error on DBInput - how to debug?

[Anonymous]

Hi!

I get a SQL error message when running a query with context variables.  I have tried to figure out what the syntax error is but I can't reproduce it manually, when replacing the context variables by hand and runs the query it works in SQL server. So how can I get my query with context variables replaced with values? I tried globalMap in a tJava but only get Null back. See below. What can I do to get the query that Talend sends to Sql server?

Can you share the query?

Hi,

    I believe you are not populating value to one of your context variables. One trick will be to print the whole query using tjava and see the output query. It would be also ideal to check the big query part by part so that you can corner the problematic area quickly.
