QSqlQuery for ms access database

[SGaist]

Can you write an example query that currently works for that use case ?

@sgaist
As i mentioned this one :

    QSqlQuery  query ;
    query.prepare("SELECT * FROM names where name like ? ");
    query.addBindValue(st);

It works but i should write entire word i want to write a part of record in my case name record and it update QTableView

What I am asking for is an example without binding that is working. Once we have that it should be easier to come with a solution.

Hi, the use of % instead of * is the right way. The * is only for using it directly on ms access query.

WHat version of ms access are you using? could you post a screenshot of your database/table?

@behruz-montazeri said in QSqlQuery for ms access database:

@sgaist
I have no idea.

Something like "SELECT * FROM names where name like '%foo%'" to confirm that one is working properly.

@sgaist
Yes that works.Then what should be inside the % % instead of foo for binding ???
what about binding ??

[RonaldViscarraL]

try this:

QSqlQuery  query ;
query.prepare("SELECT * FROM names where name like '%?%'" );
query.addBindValue("a");

I tested in Qt using access both 32 bits, this code works for me:

QString st = "a";
query->prepare("SELECT * FROM names WHERE name LIKE ?;");

QString criteria("%" + st + "%");
query->addBindValue(criteria);
