  • 0

I am attempting to use a parametrized LIKE query with Python’s Sqlite library as below:

self.cursor.execute("select string from stringtable where string like '%?%' and type = ?", (searchstr,type))

but the ? inside of the wildcard is not being evaluated leaving me with this error:

"sqlite3.ProgrammingError: Incorrect number of bindings supplied. The current statement uses 1, and there are 2 supplied."

I also tried to use the tagged version of querying with:

like '%:searchstr%' and in the list having {"searchstr":searchstr...

but when I do that the query runs but never returns any results even though manually putting in "like '%a%'"... return hundreds of results as it should

any suggestions please?

    The quotes protect either ? or :name from being taken as a place-holder — they’re taken literally. You need to place the percent signs around the string you’re passing, and use the plain placeholder without quotes. I.e.:

    self.cursor.execute(
  "select string from stringtable where string like ? and type = ?",
  ('%'+searchstr+'%', type))

    Note that neither ? is in quotes — and that’s exactly as it should be for them to be taken as placeholders.
