JDBC Insert property code 

--------------------------------------

# JDBC Connection string (Oracle, Mysql, H2, etc.)
jdbc.connect.url=jdbc:sqlserver://servername:port;databaseName=dbname

# JDBC login username
jdbc.username=user

#JDBC login password
jdbc.password=password

# Use INSERT queries to export your data into database
# Use the INSERT IGNORE command rather than the INSERT command. If a record doesn't
# duplicate an existing record, then SQL inserts it as usual. If the record is a
# duplicate, then the IGNORE keyword tells SQL to discard it silently without generating an error.
# Use the REPLACE command rather than the INSERT command. If the record is new, it is inserted
# just as with INSERT. If it is a duplicate, the new record replaces the old one.
# SQL query example
jdbc.query=insert into anaplan.dbo.py_sales (REGION, PY_SALES) values (?,?)

# -----NEW PARAMETER----
# JDBC parameters for parametrized SQL write in {jdbc.query} above.
# NOTE: The number of parameters must be equal to the number of parameters provided in the {jdbc.query} above.
# The parameter names must match column names from Anaplan export action.
# The JDBC parameters below will be mapped starting from left to right to the '?' in {jdbc.query} above.
# In this example, the exported data has columns names column1 and column2. These will be mapped
# starting from left to right to each of the '?' above.
jdbc.params="Sales Region","PY_Sales"

the above values are not original just i changed . please find the error which i am getting it  . please help me
