【问题描述】：
我有一个存储过程如下：
CREATE OR REPLACE PROCEDURE "SMEADM"."COPY_TABLE_WITH_FILTER"
(IN IN_SOURCE_TABLE_NAME VARCHAR(50), IN IN_DEST_TABLE_NAME VARCHAR(50), IN IN_WHERE_CONDITION VARCHAR(1024))
NOT DETERMINISTIC
LANGUAGE SQL
SPECIFIC SQL_SME_DATA_RETENTION
BEGIN
CALL SYSPROC.ADMIN_CMD('LOAD FROM (SELECT * FROM ' || IN_SOURCE_TABLE_NAME || ' WHERE ' || IN_WHERE_CONDITION || ' ) of cursor insert into ' || IN_DEST_TABLE_NAME || ' nonrecoverable');
END
@
这是我调用这个存储过程的java代码：
public void copyData(String srcTableName, String bakTableName, String dateColName, String sqlDateStr)
{
String sqlWhereFilter = " date(" + dateColName + ") < date('" + sqlDateStr + "')";
SimpleJdbcCall jdbcCall = new SimpleJdbcCall(this)
.withSchemaName("SMEADM")
.withProcedureName("COPY_TABLE_WITH_FILTER");
SqlParameterSource in = new MapSqlParameterSource()
.addValue("IN_SOURCE_TABLE_NAME", srcTableName)
.addValue("IN_DEST_TABLE_NAME", bakTableName)
.addValue( "IN_WHERE_CONDITION", sqlWhereFilter );
jdbcCall.execute(in);
}
在我的本地环境、SIT 环境和 UAT 环境中一切正常。
但我在生产环境中得到了SqlException。下面是我的堆栈跟踪：

我怀疑此异常是由我未授予 db 用户的某些访问权限引起的。因此，我尝试从 SIT 环境中的 db 用户中获取一些访问权限（例如加载数据库等），尝试遇到相同的异常。但是，在 SIT 中，我遇到了其他错误，这清楚地告诉我根本原因是什么，而不是错误代码 -3015
试图从 Google 获得一些提示但失败了。我想我错过了一些寻找根本原因的要点/步骤。请多多指教。

您的程序对 SQL 注入开放；当然，这样的事情需要动态 SQL，但您应该验证表名和列是否都是实际的列名和表名（可能来自存储过程中）。最好将日期参数作为实际日期类型传递（最好是新的
java.time库中的某些内容）。您可能想要显式设置并发级别。此外，如果可能，不要在 SQL 中将比较列强制转换为日期，因为这可能会导致系统忽略索引。
