使用更新查询更新 sqlite table 中的值时出现问题

Question

我正在我的 swift 项目 中实施 sqlite 并使用 update query 我正在更新来自 table 的一些 value 但我收到 语法错误 我不是确定为什么我收到 error.

更新代码

 let updateStatementString = "UPDATE CreateInspDrawingDetail SET edit_file_name = \(self.imgbase64!) WHERE property_id = \(property_ID!) AND properties_drawings_id = \(self.drawingID!)"
 var updateStatement: OpaquePointer? = nil
 if sqlite3_prepare_v2(db, updateStatementString, -1, &updateStatement, nil) == SQLITE_OK {
        if sqlite3_step(updateStatement) == SQLITE_DONE {
               print("Successfully updated row.")
        } else {
               print("Could not update row.")
        }
      } else {
            print("UPDATE statement could not be prepared")
      }
      sqlite3_finalize(updateStatement)

我收到 语法错误，如下所示

near "/": syntax error UPDATE statement could not be prepared

我的查询有什么问题请告诉我

试试这个

let updateStatementString = "UPDATE CreateInspDrawingDetail SET edit_file_name = '\(self.imgbase64!)' WHERE property_id = '\(property_ID!)' AND properties_drawings_id = '\(self.drawingID!)';"
 var updateStatement: OpaquePointer? = nil
 if sqlite3_prepare_v2(db, updateStatementString, -1, &updateStatement, nil) == SQLITE_OK {
        if sqlite3_step(updateStatement) == SQLITE_DONE {
               print("Successfully updated row.")
        } else {
               print("Could not update row.")
        }
      } else {
            print("UPDATE statement could not be prepared")
      }
      sqlite3_finalize(updateStatement)
