instead of using the getFullYear which by the way the output in an integer type which I think causing the sql select snap to haywire 🙂 you can use concat

e.g.
‘abc_’.concat(Date.now().toLocaleDateString({‘format’:‘yyyy’}))

or if you want to stick with the getFullYear() try to cast it as string

‘abc_’ + Date.now().getFullYear().toString()

    I saw this write up from a Postgesql update snap, I wonder if this applies to all database type snaps ?

    Do you mind putting a pipeline parameter and test it? If this can be allowed from the pipeline parameter then you can use an expression library and put the function there

    sample of expression file content
    {
    ‘getDynamicTableName’ : (table_prefix = “abc_”) => table_prefix.concat(Date.now().getFullYear().toString())
    }

    then set the expression file in the pipeline and invoke the method in the SQL select snap under table name

    e.g lib.extender.getDynamicTableName()

    The values can be passed using the pipeline parameters but not the upstream parameter
