Functions ¶
func AVG ¶
func AVG(col interface{}) exp.SQLFunctionExpression
Creates a new AVG sql function
AVG("a") -> AVG("a") AVG(I("a")) -> AVG("a")
Example ¶
ds := goqu.From("test").Select(goqu.AVG("col")) sql, args, _ := ds.ToSQL() fmt.Println(sql, args) sql, args, _ = ds.Prepared(true).ToSQL() fmt.Println(sql, args)
Output: SELECT AVG("col") FROM "test" [] SELECT AVG("col") FROM "test" []
Example (As) ¶
sql, _, _ := goqu.From("test").Select(goqu.AVG("a").As("a")).ToSQL() fmt.Println(sql)
Output: SELECT AVG("a") AS "a" FROM "test"
Example (HavingClause) ¶
ds := goqu. From("test"). Select(goqu.AVG("a").As("avg")). GroupBy("a"). Having(goqu.AVG("a").Gt(10)) sql, args, _ := ds.ToSQL() fmt.Println(sql, args) sql, args, _ = ds.Prepared(true).ToSQL() fmt.Println(sql, args)
Output: SELECT AVG("a") AS "avg" FROM "test" GROUP BY "a" HAVING (AVG("a") > 10) [] SELECT AVG("a") AS "avg" FROM "test" GROUP BY "a" HAVING (AVG("a") > ?) [10]
func And ¶
func And(expressions ...exp.Expression) exp.ExpressionList
A list of expressions that should be ANDed together
And(I("a").Eq(10), I("b").Eq(11)) //(("a" = 10) AND ("b" = 11))
Example ¶
ds := goqu.From("test").Where( goqu.And( goqu.C("col").Gt(10), goqu.C("col").Lt(20), ), ) sql, args, _ := ds.ToSQL() fmt.Println(sql, args) sql, args, _ = ds.Prepared(true).ToSQL() fmt.Println(sql, args)

func C ¶
func C(col string) exp.IdentifierExpression

An Identifier can represent a one or a combination of schema, table, and/or column.
C("column") -> "column" //A Column C("column").Table("table") -> "table"."column" //A Column and table C("column").Table("table").Schema("schema") //Schema table and column C("*") //Also handles the * operator

Set an error on the dataset if one has not already been set. This error will be returned by a future call to Error or as part of ToSQL. This can be used by end users to record errors while building up queries without having to track those separately.
func (*InsertDataset) ToSQL ¶
func (id *InsertDataset) ToSQL() (sql string, params []interface{}, err error)
Generates the default INSERT statement. If Prepared has been called with true then the statement will not be interpolated. See examples. When using structs you may specify a column to be skipped in the insert, (e.g. id) by specifying a goqu tag with `skipinsert`
type Item struct{ Id uint32 `db:"id" goqu:"skipinsert"` Name string `db:"name"` }
rows: variable number arguments of either map[string]interface, Record, struct, or a single slice argument of the accepted types.
Errors:
- There is no INTO clause
- Different row types passed in, all rows must be of the same type
- Maps with different numbers of K/V pairs
- Rows of different lengths, (i.e. (Record{"name": "a"}, Record{"name": "a", "age": 10})
- Error generating SQL
Example ¶
type item struct { ID uint32 `db:"id" goqu:"skipinsert"` Address string `db:"address"` Name string `db:"name"` } insertSQL, args, _ := goqu.Insert("items").Rows( item{Name: "Test1", Address: "111 Test Addr"}, item{Name: "Test2", Address: "112 Test Addr"}, ).ToSQL() fmt.Println(insertSQL, args) insertSQL, args, _ = goqu.Insert("items").Rows( goqu.Record{"name": "Test1", "address": "111 Test Addr"}, goqu.Record{"name": "Test2", "address": "112 Test Addr"}, ).ToSQL() fmt.Println(insertSQL, args) insertSQL, args, _ = goqu.Insert("items").Rows( []item{ {Name: "Test1", Address: "111 Test Addr"}, {Name: "Test2", Address: "112 Test Addr"}, }).ToSQL() fmt.Println(insertSQL, args) insertSQL, args, _ = goqu.From("items").Insert().Rows( []goqu.Record{ {"name": "Test1", "address": "111 Test Addr"}, {"name": "Test2", "address": "112 Test Addr"}, }).ToSQL() fmt.Println(insertSQL, args)
Output: INSERT INTO "items" ("address", "name") VALUES ('111 Test Addr', 'Test1'), ('112 Test Addr', 'Test2') [] INSERT INTO "items" ("address", "name") VALUES ('111 Test Addr', 'Test1'), ('112 Test Addr', 'Test2') [] INSERT INTO "items" ("address", "name") VALUES ('111 Test Addr', 'Test1'), ('112 Test Addr', 'Test2') [] INSERT INTO "items" ("address", "name") VALUES ('111 Test Addr', 'Test1'), ('112 Test Addr', 'Test2') []

ToSQL() fmt.Println(insertSQL) insertSQL, _, _ = goqu.Insert("test"). Cols("a", "b", "c"). Vals([]interface{}{"a1", "b1", "c1"}). Vals([]interface{}{"a2", "b2", "c2"}). Vals([]interface{}{"a3", "b3", "c3"}). ToSQL() fmt.Println(insertSQL)
Output: INSERT INTO "test" ("a", "b", "c") VALUES ('a1', 'b1', 'c1'), ('a2', 'b2', 'c2'), ('a3', 'b3', 'c3') INSERT INTO "test" ("a", "b", "c") VALUES ('a1', 'b1', 'c1'), ('a2', 'b2', 'c2'), ('a3', 'b3', 'c3')
