How the informatica server sorts the string values in Rank transformation?

Question

I have a SQL transformation with 2 ports. I want to insert the value of these ports to a table, however I am getting an error from sqlError port.

Below is the query I am writing in the source qualifier:

INSERT INTO A values (~QC_CODE~,(~QUERY_STRING~));

The QUERY_STRING port contains a sql statement which is executed on Teradata and results have to be inserted in the table A.

If I replace the first port in the above query with a constant value, I get correct results. Below is the query that gives correct result:

INSERT INTO A values ('1',(~QUERY_STRING~));

Answer 1

When the informatica server runs in the ASCII data movement mode it sorts session data using Binary sort order. If you configure the session to use a binary sort order, the informatica server calculates the binary value of each string and returns the specified number of rows with the highest binary values for the string.
