java - LIKE 的谓词错误

Question

int sixteen = 16;
String full="%"+sixteen+"%";
conn = PervasiveUtil.loadDriver();
stmt = conn.prepareStatement("SELECT BKAR_INV_SONUM "
                           + " FROM BKARINV "
                           + " WHERE BKAR_INV_SONUM > 150000 "
                           + " AND BKAR_INV_SONUM LIKE ?"
                           + " ORDER BY BKAR_INV_SONUM DESC");
stmt.setString(1, full);
rs = stmt.executeQuery();

此代码产生错误：

java.sql.SQLException: [LNA][Pervasive][ODBC Engine Interface]Error in predicate: BKAR_INV_SONUM LIKE ? 

BKAR_INV_SONUM 类型在数据库中是 int。这会影响我的准备语句吗？我应该使用setInt()而不是setString()吗？
