Question

我试图通过sqlplus将大于4000字符的XML文档插入到XMLType列中。

我收到错误：

ORA-01704: string literal too long

我正在遵循以下步骤：

注册架构：

BEGIN
-- Register the schema
DBMS_XMLSCHEMA.registerSchema('http://www.example.com/fvInteger_282.xsd',
'<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="FeatureVector">
<xs:complexType>
<xs:sequence>
<xs:element name="feature" type="xs:integer" minOccurs="282" maxOccurs="282"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>',
   TRUE, TRUE, FALSE);
END;
/

创建表格：

CREATE TABLE itest_xml_282 (
   id    NUMBER,
   fv  XMLTYPE)
   XMLTYPE fv STORE AS OBJECT RELATIONAL
      XMLSCHEMA "http://www.example.com/fvInteger_282.xsd"
      ELEMENT "FeatureVector";

插入XML文档：

INSERT INTO itest_xml_282 VALUES ( 1 , '<FeatureVector><feature>-1</feature><feature>18</feature><feature>21</feature><feature>-1</feature><feature>4</feature><feature>7</feature><feature>19</feature><feature>20</feature><feature>-31</feature><feature>-16</feature><feature>17</feature><feature>-3</feature><feature>21</feature><feature>14</feature><feature>50</feature><feature>22</feature><feature>-7</feature><feature>7</feature><feature>2</feature><feature>11</feature>
