从java中插入到CLOB类型时的ORA-01461字符串

我将java String类型映射到ibatis sql配置文件中的CLOB类型，并在我使用此配置插入记录时遇到ORA错误。当字符串的长度为4000个字符或更少时，这似乎工作文件。为了测试出长字符串，我创建了一个字段中包含5000个字符的随机字符串（DATA_CODE和SCHEMA_CODE）。从java中插入到CLOB类型时的ORA-01461字符串

我的SQL文件看起来像：

<parameterMap class="map" id="map"> 
<parameter property="QUERY_HASH" javaType="java.math.BigDecimal" jdbcType="NUMBER" /> 
<parameter property="LOCATION" javaType="java.lang.String" jdbcType="VARCHAR2" /> 
<parameter property="HOST_NAME" javaType="java.lang.String" jdbcType="VARCHAR2" /> 
<parameter property="SERVER_PORT" javaType="java.lang.String" jdbcType="VARCHAR2" /> 
<parameter property="DATA_CODE" javaType="java.lang.String" jdbcType="CLOB" /> 
<parameter property="SCHEMA_CODE" javaType="java.lang.String" jdbcType="CLOB" /> 
<parameter property="CREATED" javaType="java.util.Date" jdbcType="DATE" /> 
</parameterMap> 
<insert id="INSERT__QUERY_CACHE" parameterClass="map"> 
    <![CDATA[ 
    INSERT INTO "QUERY_CACHE" (query_hash, location, host_name, server_port, data_code, schema_code, created) 
    SELECT #QUERY_HASH#, #LOCATION#, #HOST_NAME#, #SERVER_PORT#, #DATA_CODE#, #SCHEMA_CODE#, #CREATED# FROM DUAL WHERE NOT EXISTS (SELECT * FROM 
    SAVRO_CONN_QUERY_CACHE WHERE query_hash = #QUERY_HASH# and location=#LOCATION# and host_name = #HOST_NAME# and server_port = #SERVER_PORT#) 
    ]]> 
</insert>

和我的Java代码：

Map<String, Object> iterMap = new HashMap<String, Object>(); 
iterMap.put("QUERY_HASH", key); 
iterMap.put("LOCATION", cacheEntry.className); 
iterMap.put("HOST_NAME", hostName); 
iterMap.put("SERVER_PORT", serverPort); 
////// junk string - START 
StringBuilder builder = new StringBuilder(); 
builder.append("5000 chars string"); 
builder.append(RandomStringUtils.random(5000)); 
iterMap.put("DATA_CODE", builder.toString()); 
iterMap.put("SCHEMA_CODE", builder.toString()); 
//// junk string - END 
iterMap.put("CREATED", new Date(System.currentTimeMillis())); 
insert(QRY__INSERT, iterMap);

异常跟踪是：

我们使用iBATIS 2.3.4春季3.3 我在其他文章搜索类似的问题，但我找不到他们的线索。任何线索请..

显然有没有简单的方法来从Java插入大的值在Oracle中，因为JDBC驱动程序没有原生支持Reader和InputStream。这是在SO的另一个主题： Java: How to insert CLOB into oracle database

我使用iBATIS。我想出了一个方法来与ibatis一起做。参考我的答案。 – sandeep

我在做insert into .. select if not exists。我的要求是仅当数据不存在于表中时才插入数据。它的工作

拆分此之后分成两个单独的查询 - 一个用于选择，一个是插入。
因为，我反正发送一个map参数，我删除了paramMap xml。

附加CLOB查询在XML

<insert id="INSERT__QUERY_CACHE" 
parameterClass="Map"> 
<![CDATA[ 
INSERT INTO "QUERY_CACHE" (query_hash, location, host_name, server_port, data_code, schema_code, created) 
values (#QUERY_HASH#, #LOCATION#, #HOST_NAME#, #SERVER_PORT#, #DATA_CODE:CLOB#, #SCHEMA_CODE:CLOB#, sysdate) 
]]> 
</insert> 

<select id="SELECT__FROM_CACHE" resultClass="int"> 
<![CDATA[ 
SELECT count(0) as CNT FROM QUERY_CACHE WHERE query_hash = #QUERY_HASH# and location=#LOCATION# and host_name = #HOST_NAME# and server_port = #SERVER_PORT# 
]]> 
</select>

在Java中指定参数时，

Map<String, Object> selectMap = new HashMap<String, Object>(); 
selectMap.put("QUERY_HASH", key); 
selectMap.put("LOCATION", cacheEntry.className); 
selectMap.put("HOST_NAME", hostName); 
selectMap.put("SERVER_PORT", serverPort); 

Integer count = (Integer) queryForObject(QRY__SELECT_FROM_CACHE, selectMap); 
if(count == 0) { 
    Map<String, Object> iterMap = new HashMap<String, Object>(); 
    iterMap.put("QUERY_HASH", key); 
    iterMap.put("LOCATION", cacheEntry.className); 
    iterMap.put("HOST_NAME", hostName); 
    iterMap.put("SERVER_PORT", serverPort); 
    iterMap.put("DATA_CODE", cacheEntry.dataCode); 
    iterMap.put("SCHEMA_CODE", cacheEntry.schemaCode); 
    insert(QRY__INSERT, iterMap); 
}
