Cl-Batis does not support DDL.
If you want to use DDL, use do-sql.
(do-sql session "truncate table product")
There are two type of methods.
updateselectwhen use (cl-syntax:use-syntax :annot), @update and @select can be used.
@update ("insert into product (id, name, price) values (:id, :name, :price)")
(defsql register-product (id name price))
@update ("update
product "
(sql-set
(sql-cond (not (null name))
" name = :name, ")
(sql-cond (not (null price))
" price = :price "))
(sql-where
" id = :id "))
(defsql update-product (id name price))
@select ("select name, price from product where id = :id")
(defsql search-product (id))
@select ("select id, name, price from product"
(sql-where
(sql-cond (not (null name))
" and name = :name ")
(sql-cond (not (null price_low))
" and price >= :price_low ")
(sql-cond (not (null price_high))
" and price <= :price_high "))
" order by id ")
(defsql filter-product (name price_low price_high))
@select
("select * from product where "
(sql-cond (not (null price))
" price = :price")
(sql-cond (not (null valid_flag))
" and valid_flag = :valid_flag"))
(defsql search-by-price (price valid_flag))
In dynamic condition, if sql-cond returns nothing, you would end up with SQL that looked like this:
select * from product where
This would fail. And, if only the second condition was met, you would end up with SQL that looked like this:
select * from product where
and valid_flag = '1'
This would also fail.
So, cl-batis provides SQL-WHERE function.
@select
("select * from product"
(sql-where
(sql-cond (not (null price))
" price = :price")
(sql-cond (not (null valid_flag))
" and valid_flag = :valid_flag ")))
(defsql search-by-product (price valid_flag))
The SQL-WHERE knows to only insert WHERE if there is any condition.
Furthermore, if that content begins with AND or OR, strip it off.
@update
("update product"
(sql-set
(sql-cond (not (null price))
" price = :price, ")
(sql-cond (not (null name))
" name = :name "))
(sql-where
" id = :id "))
(defsql update-product-info (id price name))
There is a similar solution for dynamic update statements called SQL-SET.
The SQL-SET knows to strip last comma off.
(update-one *session* register-product :id 1 :name "NES" :price 14800)
(select-one *session* search-product :id 1)
-> (:|name| "NES" :|price| 14800))

## Usage
### create session
“‘common-lisp
;; with CL-DBI connection
(defparameter *conn-dbi* (dbi:connect :mysql
:database-name "batis"
:username "nobody"
:password "nobody"))
(defparameter *session* (create-sql-session *conn-dbi*))
;; with CL-DBI-Connection-Pool
(defparameter *conn-pool* (dbi-cp:make-dbi-connection-pool :mysql

;; direct
(defparameter *session* (create-sql-session :mysql

:password "nobody"))
“‘
### how to do DDL
Cl-Batis does not support DDL.
If you want to use DDL, use ‘do-sql‘.
“‘common-lisp
(do-sql session "truncate table product")
“‘
### Define SQL
There are two type of methods.
- ‘update‘
- ‘select‘
when use ‘(cl-syntax:use-syntax :annot)‘, ‘@update‘ and ‘@select‘ can be used.
#### update
“‘common-lisp
@update ("insert into product (id, name, price) values (:id, :name, :price)")
(defsql register-product (id name price))
@update ("update
product "
(sql-set
(sql-cond (not (null name))
" name = :name, ")
(sql-cond (not (null price))
" price = :price "))
(sql-where
" id = :id "))
(defsql update-product (id name price))
“‘
#### select
“‘common-lisp
@select ("select name, price from product where id = :id")
(defsql search-product (id))
@select ("select id, name, price from product"
(sql-where
(sql-cond (not (null name))
" and name = :name ")
(sql-cond (not (null price_low))
" and price >= :price_low ")
(sql-cond (not (null price_high))
" and price <= :price_high "))
" order by id ")
(defsql filter-product (name price_low price_high))
“‘
#### where, set
“‘common-lisp
@select
("select * from product where "
(sql-cond (not (null price))
" price = :price")
(sql-cond (not (null valid_flag))
" and valid_flag = :valid_flag"))
(defsql search-by-price (price valid_flag))
“‘
In dynamic condition, if ‘sql-cond‘ returns nothing, you would end up with SQL that looked like this:
“‘SQL
select * from product where
“‘
This would fail.
And, if only the second condition was met, you would end up with SQL that looked like this:
“‘SQL
select * from product where
and valid_flag = ’1’
“‘
This would also fail.
So, ‘cl-batis‘ provides ‘SQL-WHERE‘ function.
“‘common-lisp
@select
("select * from product"
(sql-where
(sql-cond (not (null price))
" price = :price")
(sql-cond (not (null valid_flag))
" and valid_flag = :valid_flag ")))
(defsql search-by-product (price valid_flag))
“‘
The ‘SQL-WHERE‘ knows to only insert ‘WHERE‘ if there is any condition.
Furthermore, if that content begins with ‘AND‘ or ‘OR‘, strip it off.
“‘common-lisp
@update
("update product"
(sql-set
(sql-cond (not (null price))
" price = :price, ")
(sql-cond (not (null name))
" name = :name "))
(sql-where
" id = :id "))
(defsql update-product-info (id price name))
“‘
There is a similar solution for dynamic update statements called ‘SQL-SET‘.
The ‘SQL-SET‘ knows to strip last comma off.
### Execute
#### update
“‘common-lisp
(update-one *session* register-product :id 1 :name "NES" :price 14800)
“‘
#### select
“‘common-lisp
(select-one *session* search-product :id 1)
-> (:|name| "NES" :|price| 14800))
“‘
“‘common-lisp
(select-list *session* filter-product :price_low 20000)
->((:|id| 2 :|name| "SNES" :|price| 25000)
(:|id| 3 :|name| "MEGA DRIVE" :|price| 21000)
(:|id| 4 :|name| "PC Engine" :|price| 24800)))
“‘
### transaction
“‘common-lisp
(commit *session*)
(rollback *session*)
“‘
### release session
“‘common-lisp
