ljluestc fe8ba5e35f fix(database/gdb): Resolve column ambiguity in GROUP BY/ORDER BY with MySQL JOIN (#4521 )

When using JOIN queries in MySQL with the `Group()` method, column names
in GROUP BY clauses become ambiguous if multiple tables contain columns
with the same name (commonly `id`). This results in MySQL errors like
"Column 'id' in group statement is ambiguous".

**Example Issue:**
```go
model := t.Ctx(ctx).Fields("t_inf_job.*, t_inf_job_attr.*").
    LeftJoin("t_inf_job_attr", "t_inf_job.id = t_inf_job_attr.job_id").
    Where(t.Columns().Deleted, 0)

// This would fail with "Column 'id' in group statement is ambiguous"
err = model.Group(t.Columns().Id).Scan(&jobs)
```


### **Key Changes**

1. **Modified function signature**: `Group(groupBy ...string)` →
`Group(groupBy ...any)` to support Raw SQL expressions
2. **Auto-prefixing logic**: When JOINs are detected (by checking for "
JOIN " in the tables string), unqualified column names are automatically
prefixed with the primary table name
3. **Preserved existing behavior**: Already qualified columns
(containing ".") and Raw expressions are handled as before
4. **Added comprehensive test**: `Test_Model_Group_WithJoin` verifies
the fix works correctly with JOIN queries

Database drivers

Powerful database drivers for package gdb.

Installation

Let's take mysql for example.

go get -u github.com/gogf/gf/contrib/drivers/mysql/v2
# Easy to copy
go get -u github.com/gogf/gf/contrib/drivers/clickhouse/v2
go get -u github.com/gogf/gf/contrib/drivers/dm/v2
go get -u github.com/gogf/gf/contrib/drivers/mssql/v2
go get -u github.com/gogf/gf/contrib/drivers/oracle/v2
go get -u github.com/gogf/gf/contrib/drivers/pgsql/v2
go get -u github.com/gogf/gf/contrib/drivers/sqlite/v2
go get -u github.com/gogf/gf/contrib/drivers/sqlitecgo/v2

Choose and import the driver to your project:

import _ "github.com/gogf/gf/contrib/drivers/mysql/v2"

Commonly imported at top of main.go:

package main

import (
	_ "github.com/gogf/gf/contrib/drivers/mysql/v2"

	// Other imported packages.
)

func main() {
	// Main logics.
}

Supported Drivers

MySQL/MariaDB/TiDB

import _ "github.com/gogf/gf/contrib/drivers/mysql/v2"

SQLite

import _ "github.com/gogf/gf/contrib/drivers/sqlite/v2"

cgo version

When the target is a 32-bit Windows system, the cgo version needs to be used.

import _ "github.com/gogf/gf/contrib/drivers/sqlitecgo/v2"

PostgreSQL

import _ "github.com/gogf/gf/contrib/drivers/pgsql/v2"

Note:

It does not support Replace features.
