pass a property to JDBC post processor in Jmeter

Solution 1:

Either just go for __P() function like:

${__P(some_id,)}

or use the correct syntax for the __groovy() function like:

${__groovy(props.get('some_id'),)}

If you're uncertain regarding proper syntax for this or that function - consider using the Function Helper Dialog
