[Seasar-user:16451] 【S2JDBC】タイプセーフのLIKE 〜 ESCAPE演算子を使用時に例外が発生

[Takeshi Motegi]

茂木です。

S2JDBCのタイプセーフを色々と試しているのですが、ちょっとあれっ？て
例外が発生しました。

以下の環境で、
・sa-struts-1.0.4-sp2.jar
・s2-framework-2.4.32.jar
・s2-extension-2.4.32.jar
・s2-tiger-2.4.32.jar
・s2jdbc-gen-0.9.3.jar
・hsqldb.jar（1.8.0.10）
・HSQLDB使用テーブル　→　HSQLDBのファイルを添付しました。

s2jdbc-genでgen-entityをターゲットにしてソースを自動生成しました。そして、
EmployeeServiceクラスに、タイプセーフのLIKE 〜 ESCAPE演算子を使用する
以下のメソッドを追加して実行しました。

public List<Employee> findByName() {
    return select().where( like(name(), "$_AbelCain", 
"$") ).getResultList();
}

ところが、↓のような例外が発生してしまいました。内容を見るとプレースホルダーに 

パラメータが渡っていないままにSQLを実行してしまっているようですが、使い方が何か
まずいのでしょうか？

致命的: サーブレット default のServlet.service()が例外を投げました
java.sql.SQLException: Invalid escape character in statement [select T1_.ID 
as C1_, T1_.NAME as C2_, T1_.JOB_TYPE as C3_, T1_.SALARY as C4_, 
T1_.DEPARTMENT_ID as C5_, T1_.ADDRESS_ID as C6_, T1_.VERSION as C7_ from 
EMPLOYEE T1_ where (T1_.NAME like ? escape ?)]
