SQL CLOB 是 内置类型,它将字符大对象 (Character Large Object) 存储为数据库表某一行中的一个列值。默认情况下, 驱动程序使用 SQL locator(CLOB) 实现 Clob 对象,这意味着 CLOB 对象包含一个指向 SQL CLOB 数据的逻辑 指针而不是数据本身。Clob 对象在它被创...

通常,Oracle JDBC驱动会确保 oracle.sql.CLOB 实例可以无缝地用作 java.sql.CLOB,因为 oracle.sql.CLOB 实现了 java.sql.CLOB 接口。这意味着在大多数情况下,你不需要显式地进行类型转换。 直接转换: 如果你的代码中有一个 oracle.sql.CLOB 对象,并且你需要将它作为 java.sql.CLOB 使用,你可以直接将 oracle...

I first reported my problem on StackOverflow as question thinking it was a usage problem on how to merge into oracle with a CLOB column ( https://stackoverflow.com/questions/77100531/jooq-how-to-merge-with-oracle-clob-column-fitting-into-a-string ) but now I have spent some more thoughts...
Open a CLOB in the indicated mode. SQLXMLtoSQLXML() Returns an object which impements java.sql.SQLXML with content take from this Clob. SQLXMLtoSQLXML(StringschemaURL) Returns an object which impements java.sql.SQLXML with content taken from this Clob. ...
