in参数化sql查询中的运算符

Question

我想从一个使用参数化sql查询的集合中搜索一个特定的值，不管它是什么，或者不是这个的SQL查询

Answer 1

据我所知，prepareStatement不能使用逗号分隔的IN()子句列表。 您可以使用以下简单的内容：

private static final domainListPlaceHolder =  "<DOMAINS_LIST>";

String sql = "select p.DEALER_NAME from DEALER_PROFILE as p,DEALER_DOMAIN as d,
DELER_PROFILE_DOMAIN as pd where d.DOMAIN_ID = pd.DOMAIN_ID 
and d.DOMAIN_NAME IN (<DOMAINS_LIST>) and pd.DEALER_ID= p.DEALER_ID";

// build a comma delimited String from your array (each domain wrapped with ''), called domainList

String sqlToRun = sql.replace(domainListPlaceHolder, domainList);
