Overview

Builders

Insert Builder

package main

import (
  "fmt"
  . "github.com/go-the-way/sg"
)

func main() {
  builder := InsertBuilder().
    Table(T("table_person")).
    Column(C("col1"), C("col2")).
    Value(Arg(100), Arg(200))
  fmt.Println(builder.Build())
  // Output:
  // INSERT INTO table_person (col1, col2) VALUES (?, ?) [100 200]
}

Delete Builder

package main

import (
	"fmt"
	. "github.com/go-the-way/sg"
)

func main() {
	builder := DeleteBuilder().
		Delete(T("t1.*")).
		From(As(C("table1"), "t1"), As(C("table2"), "t2")).
		Where(AndGroup(Gt("t1.col1", 100), Gt("t2.col2", 200)))
	fmt.Println(builder.Build())
	// Output:
	// DELETE t1.* FROM table1 AS t1, table2 AS t2 WHERE ((t1.col1 > ?) AND (t2.col2 > ?)) [100 200]
}

Update Builder

package main

import (
	"fmt"
	. "github.com/go-the-way/sg"
)

func main() {
	builder := UpdateBuilder().
		Update(As(T("table_person"), "t")).
		Join(LeftJoin(As(T("table_a"), "ta"), On(C("t.col1 = ta.col1")))).
		Set(SetEq("col1", 100), SetEq("col2", 200)).
		Where(AndGroup(Eq("a", 100), Eq("b", 200)))
	fmt.Println(builder.Build())
	// Output:
	// UPDATE table_person AS t LEFT JOIN table_a AS ta ON (t.col1 = ta.col1) SET col1 = ?, col2 = ? WHERE ((a = ?) AND (b = ?)) [100 200 100 200]
}

Select Builder

package main

import (
	"fmt"
	. "github.com/go-the-way/sg"
)

func main() {
	builder := SelectBuilder().
		Select(C("a"), C("b")).

		Join(LeftJoin(As(T("table_a"), "ta"), On(C("ta.col1 = tb.col1")))).
		Where(AndGroup(Eq("a", 100), Eq("b", 200))).
		OrderBy(DescGroup(C("a"), C("b")))
	fmt.Println(builder.Build())
	// Output:
	// SELECT a, b FROM table_person LEFT JOIN table_a AS ta ON (ta.col1 = tb.col1) WHERE ((a = ?) AND (b = ?)) ORDER BY a DESC, b DESC [100 200]
