memtrip / sqlking Goto Github PK

Hi Sam,

Have you got a simple example of a query involving a join between two tables?

Thanks,
Adrian

Hi Sam,

Everything is resolving, except for the Q class. Can you give me a quick rundown of what I should do to configure this?

Also, I had to add
compile 'com.memtrip.sqlking:common:1.0.4'" to my build.gradle, alongside
apt 'com.memtrip.sqlking:preprocessor:1.0.4' and
compile 'com.memtrip.sqlking:client:1.0.5'

Thanks!

Hi Sam,

What is the syntax for Foreign Key/Index annotation?

Regards,
Adrian

Hi Sam,

Have you considered adding an @PrimaryKey option to the annotations? Currently, AutoNumber of the PK is not supported. Is there a workaround for this perhaps?

Thanks,
Adrian

Hi,

I've just tried to update to the new version of SQLKing. It is completely different from the first version, and has several dependencies. One of them is the android-apt plugin, but I can't get gradle to recognise 'apt'.

Have you perhaps got a small demo project that implements a full SQLKing example?

Thanks in advance,
Adrian

Hi Sam,

I would like to be able to either ignore static members, or specifically to ignore one called "CREATOR".

This would allow for adding parcelable implementation to a Table.

Would this be possible?

I think it could be done without too much trouble, as follows in Column.Java:

`
private List assembleMembers(Element element) {
List columns = new ArrayList<>();

    if (element.getEnclosedElements() != null && element.getEnclosedElements().size() > 0) {
        for (Element childElement : element.getEnclosedElements()) {
            if (childElement.getKind().isField()) {
                **if (!childElement.getSimpleName().toString().equals("CREATOR")) {**
                    columns.add(new Column(childElement));
                }
            }
        }
    }

    return columns;
}`

Hi,

Any idea why I might be getting this error at line:

"import javax.annotation.processing.Filer;"

in the com.memtrip.sqlking.preprocessor.processor.validation.context package?

I've recently had to reinstall AS 2.1, perhaps that has something to do with it?

Many thanks,
Adrian

Hi Sam,

Q.java is being generated, but I can't seem to import it or get my app to see it. I'm using my local repository (with some changes). Common and Preprocessor are building and installing, as does the client (I have set the version on all modules to 1.1.2)

This is new behaviour, possibly prompted by recent updates to my Android Studio.

Do you have any suggestions?

Regards,
Adrian

Hi Sam, thanks a mill for the 1.0.6 release. I have a new problem now:

in one of my tables, I have the following:

`@Table
public class TblMapVisitor2Entry extends ScanTableBase implements Parcelable
{

@Column(index = true, foreign_key = "TblEntry")
private int     entry_fk;
@Column private int entry_reason;   // E_ENTRY_REASON

`
and it generates the following error:

error: [A @column with a foreign_key can only annotate a variable whose data type is annotated with @table]

What is the correct way to do this? Please note, that all of my tables extend from ScanTableBase, which looks like this:

`@Table
public class ScanTableBase
{
// Fields common to all tables
@column protected int id;
@column protected int synch_status;

@Column protected long        synch_date;       // Last good synch date
@Column protected boolean     deleted;
...
 }

`
Perhaps this is rocking the boat a bit?

Thanks,
Adrian

Hi Sam,

I'm getting the following error, and I can't see what is causing it, have you got any thoughts on this?

Caused by: java.lang.NullPointerException

Also, please can you give tell me what the annotation syntax is for setting up foreign keys and indexes?

Thanks,
Adrian

Hi Sam,

Is it possible to retrieve columns from tables that have been joined? Looking at the examples in the tests, it seems that only the root table columnset is returned.

eg. below, the return is of Class User, I can't see how to retrieve the Log columns.

        User[] users = Select .getBuilder()
                .join(innerJoin(Log.class, on("User.logId", "Log.id")))
                .execute(User.class, getSQLProvider());

Thanks,
Adrian

Hi Sam,

While trying to install the client locally (for release 1.1), I discovered the following in the client/build.gradle:

androidTestApt 'com.memtrip.sqlking:preprocessor:1.0.17'

After changing the version:

androidTestApt 'com.memtrip.sqlking:preprocessor:1.1'

The client now successfully builds.

JTYSK ;)

Hi Sam,

Just to let you know, I'm busy adding support for composite Foreign Keys and indexes, will issue a pull request shortly :)

Cheers,
Adrian

Hi Sam,

I've tried to model a 1-Many relationship, where I query a parent table joined to a child table, and expect to get a list or array of the child table returned as an object in the parent table record, but SQLKing does not support that yet.

Similar to that, where I have a self-referential table implementing a recursive hierarchy (which obviously also needs to return a list or array of it's own table type as a child, in the parent object.

Any chance of adding that soon?

Thanks,
Adrian

Hi Sam,

I'm getting an error on trying to execute a query with some nested joins. An SQLite exception is thrown as follows:

ERR: exMsg=no such column: TblMapVisitor2Entry.visitor_idINNER (code 1): ,
 while compiling: SELECT TblEntry.id,
 TblEntry.synch_status,
 TblEntry.synch_date,
.. (omitted for clarity).

The query code is:

        TblEntry[] entries =
            Select.getBuilder()
                .join (
                        innerJoin (
                                TblMapVisitor2Entry.class,
                                innerJoin (
                                          TblVisitor.class,
                                          on("TblVisitor.id", "TblMapVisitor2Entry.visitor_id"
                                          )
                                ),
                                on("TblMapVisitor2Entry.entry_id", "TblEntry.id")
                               ),
                      innerJoin (
                                TblMapVehicle2Entry.class,
                                innerJoin (
                                          TblVehicle.class,
                                          on("TblVehicle.id", "TblMapVehicle2Entry.visitor_id")
                                          )
                                )
                     )
                .orderBy(Q.TblEntry.ENTRY_DATE, OrderBy.Order.DESC)
                .limit(1, 10)
                .execute(TblEntry.class, ScanDB.sqlProvider);

It looks like a simple case of the INNER clause just not getting some whitespace in front of it. Can you help here?

Thanks,
Adrian

Hi Sam,

I have a table that has two FK's in it as follows:

public class TblMapVisitor2Entry extends BaseObservable implements Parcelable
    {
    @Column(index = true) private int       id;
    @Column private TblEntry   tblEntry;
    @Column private TblVisitor tblVisitor;

and in Q.Java, I get an error on duplicate symbols as follows:

      for (int i = 0; !cursor.isAfterLast(); i++) {
        com.thorburn.sanscan.scanDB.TblMapVisitor2Entry tblmapvisitor2entry =
            new com.thorburn.sanscan.scanDB.TblMapVisitor2Entry();

        com.thorburn.sanscan.scanDB.TblEntry tblentry = new com.thorburn.sanscan.scanDB.TblEntry();
        tblmapvisitor2entry.setTblEntry(tblentry);

        com.thorburn.sanscan.scanDB.TblVisitor tblvisitor =
            new com.thorburn.sanscan.scanDB.TblVisitor();
        tblmapvisitor2entry.setTblVisitor(tblvisitor);

        com.thorburn.sanscan.scanDB.TblEntry tblentry = new com.thorburn.sanscan.scanDB.TblEntry();
        tblmapvisitor2entry.setTblEntry(tblentry);

        com.thorburn.sanscan.scanDB.TblVisitor tblvisitor =
            new com.thorburn.sanscan.scanDB.TblVisitor();
        tblmapvisitor2entry.setTblVisitor(tblvisitor);

You can see that 'tblentry' and 'tblvisitor' variables are being declared twice. I have had a look at the preprocessor template source for Q.Java but can't see how it could be happening. I'm currently taking a shot at fixing it, but not having much success.

Please can you take a look?

Thanks,
Adrian
