sqlarray and sqlite [message #54819]

Hi everyone,

I've been looking over the example for sqlite and these forums, and basically I want to bind my table to the array... When I try to code this, I get "not defined" errors, and I am not seeing where in the example these things were defined other than the schema. I'm lost as to where to move forward here, before adding query functions etc.

My schema:

TABLE (tbl_customers)
	INT	(id) NOT_NULL PRIMARY_KEY AUTO_INCREMENT
	STRING (name, 150) NOT_NULL
	STRING (email, 150)
	STRING (contact, 150)
	STRING (address, 150)
	STRING (city, 50)
	STRING (state, 20)
	STRING (zip, 10)
	INT (taxable) NOT_NULL
END_TABLE

My include file:

sqlinclude.h:
#ifndef _Invoices_sqlinclude_h_
#define _Invoices_sqlinclude_h_
#include <SqlCtrl/SqlCtrl.h>
#include <plugin/sqlite3/Sqlite3.h>

#define SCHEMADIALECT <plugin/sqlite3/Sqlite3Schema.h>
#define MODEL "Invoices/Tables/Invoices.sch"
#include <Sql/sch_header.h>

#endif

customers.h:
#ifndef _Invoices_customers_h_
#define _Invoices_customers_h_
#include "Invoices/sqlinclude.h"
struct CustomersWindow : WithCustomersWindowLayout<TopWindow> {
public:
	CustomersWindow();
	void Paint(Draw& w) {
        w.DrawRect(GetSize(), Color(204, 255, 255)); // <= enter your background color here
     }
};
	

#endif

In my layout I have ITEM(SqlArray, CustArray, LeftPosZ(436, 656).TopPosZ(28, 420))

And my cpp code:

#include "Invoices.h"
#include "customers.h"

CustomersWindow::CustomersWindow() {
	CtrlLayout(*this, "Customers");
	
	CustArray.SetTable(tbl_customers);
	
	CustArray.AddKey(id);
	// CustArray.Join(BOOK_ID, book); // joins id from other db to this id
	CustArray.AddColumn(name, "Name"); // .SetConvert(DateIntConvert());
	CustArray.AddColumn(email, "Email"); // .SetConvert(DateIntConvert());
	CustArray.AddColumn(contact, "Phone");
	CustArray.AddColumn(address, "Address");
	CustArray.AddColumn(city, "City");
	CustArray.AddColumn(state, "State");
	CustArray.AddColumn(zip, "Zip");
	CustArray.AddColumn(taxable, "Taxable?");
	CustArray.ColumnWidths("50 50 20 50 20 15 10 2");
	CustArray.SetOrderBy(id);
	// CustArray.WhenBar = THISBACK(BorrowMenu);
	// CustArray.WhenLeftDouble = THISBACK(EditBorrow);
	CustArray.GoEndPostQuery();
}

None of the ids from the schema are recognized, so I have to declare the table another way?
Thank you all for the guidance...

Jim

Additional info: My original app has a customerstable.cs definition file (converted to c):

struct customersTable
{
	int id;
	String name;
	String email;
	String contact;
	String address;
	String city;
	String state;
	String zip;
	int taxable;
};

Do I need something like this here?
Thanks.

Ok - In the upper left of Upp, I right click and add packages Sql, SqlCtrl, and plugin/sqlite3... and in customers I add this line:
SqlId tbl_customers("tbl_customers"), id("id"), name("name"), email("email"), contact("contact"), address("address"), city("city"), state("state"), zip("zip"), taxable("taxable");

That replaces my table structure, and the code compiles without a problem. Next up, getting the table to show up in the sql array with a query I think...

Last post of the evening, I promise Wink

I now have my table populated with values, not sure if this is the best way (I'm a newb at this after all) but here's the working code:

#include "Invoices.h"
#include "customers.h"

#define SCHEMADIALECT <plugin/sqlite3/Sqlite3Schema.h>
#include "Sql/sch_source.h"


CustomersWindow::CustomersWindow() {
	String DBFile;
	String configfile = ConfigFile();
	CtrlLayout(*this, "Customers");
	
	if(FileExists(configfile))
	{
        VectorMap<String, String> cfg = LoadIniFile(configfile);
        DBFile = cfg.Get("DBFile", Null);
	}
	else 
	{
		Exclamation("Can't find DB");
	}
	SQL;
	Sqlite3Session sqlite3;
	if(!sqlite3.Open(DBFile)) {
		Exclamation("Can't create or open database file\n");
		return;
	}
	SQL = sqlite3;
	SqlId tbl_customers("tbl_customers"), id("id"), name("name"), email("email"), contact("contact"), address("address"), city("city"), state("state"), zip("zip"), taxable("taxable");

	CustArray.SetTable(tbl_customers);
		
	CustArray.AddKey(id);
	// CustArray.Join(BOOK_ID, book); // joins id from other db to this id
	CustArray.AddColumn(name, "Name"); // .SetConvert(DateIntConvert());
	CustArray.AddColumn(email, "Email"); // .SetConvert(DateIntConvert());
	CustArray.AddColumn(contact, "Phone");
	CustArray.AddColumn(address, "Address");
	CustArray.AddColumn(city, "City");
	CustArray.AddColumn(state, "State");
	CustArray.AddColumn(zip, "Zip");
	CustArray.AddColumn(taxable, "Taxable?");
	CustArray.ColumnWidths("40 40 20 50 20 15 10 5");
	CustArray.SetOrderBy(id);
	
	Sql sql(sqlite3);
	sql.Execute("select * from tbl_customers");


	while(sql.Fetch())
		CustArray.Add(sql);
	// CustArray.WhenBar = THISBACK(BorrowMenu);
	// CustArray.WhenLeftDouble = THISBACK(EditBorrow);
	CustArray.GoEndPostQuery();
}

Good night all ...

If you add '_' to .sch definition

TABLE_ (tbl_customers)
	INT_	(id) NOT_NULL PRIMARY_KEY AUTO_INCREMENT
	STRING_ (name, 150) NOT_NULL

it will make it produce SqlId constants that you are defining in the constructor. However, populating global namespace with such variables would not be a good idea, that is why standard in U++ is upppercase for sql constants to minimize name clashes.

Also struct customersTable is in fact produced by .sch mechanism as S_customersTable too and you can fetch it from the table, insert it etc... It is not needed, but sometimes handy.

Ok, I've modded the files per Mirek's suggestions, but I keep hitting a wall here Sad

Sad

I get the error:
/home/james/upp/MyApps/Invoices/UI/customers.cpp (33): error: use of undeclared identifier 'CUSTOMERS'; did you mean 'CUSTOMERID'?

So, I change:
CustArray.SetTable(CUSTOMERS, CUST_ID);

CustArray.SetTable(S_CUSTOMERS, CUST_ID);

And I get:

	STRING_ (STATE, 20)
	STRING_ (ZIP, 10)
	INT_ (TAXABLE) NOT_NULL
END_TABLE

All caps, as suggested, and changed some ids to make all unique.

Obviously I have a mistake (mistakes?) here somewhere but I can't seem to find them? Any (more) help would be appreciated Smile

Thanks y'all Smile

EDIT: I just realized that I didn't add _ to TABLE... Fixed it Smile

Your .sch creates

SqlId CUSTOMERS("CUSTOMERS");

struct S_CUSTOMER {
.....
};

SetTable obviously needs CUSTOMERS as parameter....

Additional suggestion: CustArray is SqlArray, right? In that case it is better to leave fetching the data to

CustArray.Query();

You can also add where condition e.g.:

CustArray.Query(EMAIL == "smith@email.com");

Sql sql(sqlite3);

You do need to specify the session here, as you have assigned a global default session by

SQL = sqlite3;

And it is better to avoid text SQL commands with SqlExp:

	sql.Execute("select * from CUSTOMERS");

sql * SelectAll().From(CUSTOMERS);

see https://www.ultimatepp.org/src$Sql$SqlExp_en-us.html

This way your commands get at least partially checked by C++ compiler and more importantly it avoids SQL injection problem.

Yes, I caught that and had corrected it, thank you...

That URL is perfect - I missed that in my searches obviously... I was wondering how to do more as in my c#:

        public bool Delete(customersTable dc)
        { ...
                //SQL Query to Delete Data from database
                string sql = "DELETE FROM CUSTOMERS WHERE CUST_ID=@id";

                //SQL command to pass the value
                SQLiteCommand cmd = new SQLiteCommand(sql, conn);
                //Passing the value
                cmd.Parameters.AddWithValue("@id", dc.CUST_ID);
                //Open DB Connection
                conn.Open();
                //integer variable
                int rows = cmd.ExecuteNonQuery();
                if(rows>0) //Success
                {
...

Thank you again Smile

Yeah, thats crazy, compared to

SQL * Delete(CUSTOMERS).Where(CUST_ID == id);

I see that now LOL but I keep getting an xmessage fatal error, invalid memory access when I change

sql.Execute("select * from CUSTOMERS");
to
sql * SelectAll().From(CUSTOMERS);

And then run the program...

Not enough context to figure that out.

However, in case of crashes, usually the fastest route is to run it in debugger (just press F5), then investigate backtrace. You can even copy it (in Debug/Copy backtrace of all threads) and send here.

I do not see apparent reason in the code posted. One suspicios line is

SQL;

which should normally do nothing, but would crash if you have assigned a session prior to constructor and that session was meanwhile destroyed.

If you can .zip the whole package and post here, I am glad to investigate further.

BTW, you do not need to do that SelectAll query here if you are using SqlArray::Query (that one does its own select).

Thank you for looking at this and for all your help, Mirek...

I've stripped things down to the main and one (customers) module, with a few support files, and everything is compiling and running without error now.

For curiosity's sake, I'm putting the current zip here. And again, I wish I'd found this site a long time ago!

I realize that I've been going about this all wrong...
I've been trying to do a 1 - 1 conversion from my c# code to the c++ and U++... That's wrong thinking.

I need to embrace the U++, so I went back to the examples, and am using the book borrowing app. I've come up with the following code:

#include "customers.h"
#define MODEL <Invoices/Tables/Invoices.sch>
#include <Sql/sch_source.h>

#undef MODEL
class AddCustomer : public WithCustomerAddLayout<TopWindow> {

		AddCustomer();

Now, when I run this, it gets to line 109:
SQL * Select(CUST_ID).From(CUSTOMERS).Where(CUST_ID == idNum);

And gives me an invalid memory access with:

I may have fixed my own problem, and found my mistake... in my code, I was using sql statements to generate the global SQL in the customers module. I needed to move those to the main line. So here's tne new code for anyone looking:

#main.cpp
#include "Invoices.h"

#define MODEL "Invoices/Tables/Invoices.sch"
#include <Sql/sch_schema.h>
#undef MODEL

//	bar.Sub(t_("Transactions"), THISFN(TransactionsMenu));
//	bar.Sub(t_("Reports"), THISFN(ReportsMenu));
	bar.Sub(t_("Management"), THISFN(ManagementMenu));
	bar.Add(t_("Exit"), THISFN(Close));
}
/*

	listinvoiceswin.Open(this); });
	bar.Add(t_("List Line Items"), [=]{ if(!listlineitemswin.IsOpen())
	listlineitemswin.Open(this); });
}

{
	bar.Add(t_("Income / Sales Tax"), [=]{ if(!taxreportwin.IsOpen()) taxreportwin.Open(this); });
	bar.Add(t_("Income / Sales Tax by Customer"), [=]{ if(!taxbycustomerwin.IsOpen()) taxbycustomerwin.Open(this); });

I have looked through the code and I am impressed, you got it almost all right in really record time!

Some tidbits:

	SQL * Select(dlg.ctrls).From(LINEITEMS).Where(LINEITEM_ID == idNum);

Using SQL for Select with Fetch loop is possible but not quite recommended (mostly on past experience, I have shoot my leg several times here Smile

Smile

. The problem is that very often your Fetch loop will call some routine and that routine will use SQL for something else (e.g. Update or another Select) and that will erase the current resultset... Better declare Sql sql and fetch from this.

Note that usage like SQL % Select ... (selecting single value from single line, no fetching) is still fine.

Value ConvLineItemCls::Scan ( const Value &q ) const

I see that you have not used it afterwards, but anyway... Scan is supposed to convert from "display" format - usually text - to Value. Your usage seems exactly opposite. I guess it should have been Format here (format from Value to usually text).

SQL & ::Insert(LINEITEMS)

Sql::operator& is deprecated. It makes the statment throw exception, but that approach was not quite as useful as it seemed. Use * and test for error aftewards...

I have eliminated the need for the line item convert functions, and cleaned up more code in lineitems & createinvoice Smile

Thank you!

I'm keeping github updated, https://github.com/phoenixjim/Invoices - easy access for all.

I think you should get your Values right....

StrDbl(arrayLineItems.GetColumn(i,2).ToString())

This is really not how we meant it Smile

Smile

In general, GetColumn returns Value and if you have put double into ArrayCtrl or SqlArray, it will return double Value back. So normally above should be something like

(double)arrayLineItems.GetColumn(i,2);

Also

 	SQL * Select(CUST_ID, CUSTNAME).From(CUSTOMERS);
 	while (SQL.Fetch())
 	{
 		cbCustomers.Add(~SQL[CUST_ID], ~SQL[CUSTNAME]);
 	}

operator~ in this context converts perfectly good typed Value into String. Probably not something I would do to CUST_ID.

if (txtPrice.GetData().IsNull()) return;

You can just write IsNull(txtPrice). Instead of GetData, consider using operator~ (that in U++ has general meaning something like "other value representation").

arrayLineItems.AddColumn("Description", 80);
....
(DESCRIPTION, arrayLineItems.GetColumn(i,1).ToString())

Sometimes it is worth providing IDs even if you are not directly dealing with SQL, leads to cleaner code

arrayLineItems.AddColumn(DESCRIPTION, "Description", 80);
....
(DESCRIPTION, arrayLineItems.GetColumn(i,DESCRIPTION))

(ToString here is not needed as well as AFAIK it is already String).

	SQL * Select(TAXABLE).From(CUSTOMERS).Where(CUST_ID == idNum);
	SQL.Fetch();
	optCustTaxable.Set(SQL[0]);

As this is pretty common code, there is a shortcut:

	optCustTaxable.Set(SQL % Select(TAXABLE).From(CUSTOMERS).Where(CUST_ID == idNum));

arrayLineItems.AddColumn(DESCRIPTION, "Description", 80);

(DESCRIPTION, arrayLineItems.GetColumn(i,DESCRIPTION))

Only one issue when I implement these, I keep getting:

102	if (optCustTaxable.Get() == true && arrayLineItems.GetColumn(i, ISTAXABLE)  == 1) {
103	     taxable = round((double)arrayLineItems.GetColumn(i, PRICE) * (double)arrayLineItems.GetColumn(i, QTY), 2);

/home/james/upp/MyApps/Invoices/UI/CreateInvoice.cpp (102): error: no viable conversion from 'Upp::SqlId' to 'int'
/home/james/upp/MyApps/Invoices/UI/CreateInvoice.cpp (103): error: no viable conversion from 'Upp::SqlId' to 'int'
...
/home/james/upp/MyApps/Invoices/UI/CreateInvoice.cpp (171): error: no viable conversion from 'Upp::SqlId' to 'int'

Every GetColumn call in the code generates this error?
