ScalikeJDBC SQLSyntax Extension

ScalikeJDBC SQLSyntax Extension: eq/ne/like with ignore case, and escape clause.

Case insensitivity

SQLSyntax	SQL
sqls.ieq(column.title, "abc")	LOWER(title) = LOWER('abc')
sqls.ine(column.title, "abc")	LOWER(title) <> LOWER('abc')
sqls.ilike(column.title, "%abc%")	LOWER(title) LIKE LOWER('%abc%')
sqls.notILike(column.title, "%abc%")	LOWER(title) NOT LIKE LOWER('%abc%')

Escaping operands with the LIKE predicate

SQLSyntax	SQL
sqls.like(column.title, "%#%0D#%0A%").escape("#")	title LIKE '%#%0D#%0A%' ESCAPE '#'
sqls.notLike(column.title, "%#%0D#%0A%").escape("#")	title NOT LIKE '%#%0D#%0A%' ESCAPE '#'
sqls.ilike(column.title, "%#%0D#%0A%").escape("#")	LOWER(title) LIKE LOWER('%#%0D#%0A%') ESCAPE '#'
sqls.notILike(column.title, "%#%0D#%0A%").escape("#")	LOWER(title) NOT LIKE LOWER('%#%0D#%0A%') ESCAPE '#'

Examples

import com.github.roundrop.scalikejdbcext.sqlsyntax._

// eq with ignore case
val name = "alice"
val alice: Option[Member] = withSQL {
  select.from(Member as m).where(sqls.ieq(m.name, name))
}.map(rs => Member(rs)).single.apply()
// --> select m.id as i_on_m, ... from members m where LOWER(m.name) = LOWER('alice');

// like with ignore case
val s = "b"
val q = scalikejdbc.LikeConditionEscapeUtil.contains(s) // "b" => "%b%"
val b: Seq[Member] = withSQL {
  select.from(Member as m).where(sqls.ilike(m.name, q))
}.map(rs => Member(rs)).list.apply()
// --> select m.id as i_on_m, ... from members m where LOWER(m.name) like LOWER('%b%');

// use escape clause
val escapeChar = "#"
val util = scalikejdbc.LikeConditionEscapeUtil(escapeChar)
val s = "_100%"
val q = util.endsWith(s)  // "_100%" => "%#_100#%"
val x: Seq[Member] = withSQL {
  select.from(Member as m).where(sqls.like(m.name, q).escape(escapeChar))
}.map(rs => Member(rs)).list.apply()
// --> select m.id as i_on_m, ... from members m where m.name like '%#_100#%' ESCAPE '#';
