longtext

mysql转oracle数据库时，若表中存在long型字段（length>=4096），读取表数据有时会报错“java.sql.SQLException: 流已被关闭” 。 debug之后发现是因为数据库表中存在longtext 类型的数据，oracle没有这种类型。oracle有个等价的类型，叫clob。可参考 StackOverflow上的介绍 。因此将该字段改为clob类型的就OK了。 用注解的方式： @Entity public class domain { @Column(length = 4096) private String richText; } 改为 public class domain { @Lob @Basic(fetch = FetchType.LAZY) @Column(columnDefinition = "CLOB", nullable = true) private String richText; } 来源： oschina 链接： https://my.oschina.net/u/875046/blog/129288

One of my entities Machinery has got a String property called notes . JPA 2-Hibernate generates the schema for me, in my case the RDBMS is a MySQL. notes is created as a VARCHAR(255) column, which is right. Users begin to create records and all works perfectly, but then some users get the infamous Data too long for column "notes" error. That field hasn't enough room for user's machinery notes! Ok, no problem. Let's change the schema! So, I open my entity class and change my property to: @Column(length=1000000) @Lob private String notes; By the way, my persistence.xml declares: <property name=

Unfortunatelly I am not able to make ellipsize for EditText works. Is even possible to put three dots at the end of the text when the text is too long? It is working perfectly for TextiView but not for EditText.

What is the disadvantage to using a MySQL longtext sized field when every entry will fit within a mediumtext sized field? The reason I am asking is because I have some longtext sized fields and recently realized they are much too large, but then struggled with motivating myself to make the minute change because "what's the harm?" hence the question. mu is too short The only storage size difference is the number of bytes allocated for the "how many bytes is this field" number. From the fine manual : TINYTEXT L + 1 bytes, where L < 2^8 TEXT L + 2 bytes, where L < 2^16 MEDIUMTEXT L + 3 bytes,

I'm trying to store a String which contains HTML in a MySQL database using Longtext data type. But it always says "You have an error in your SQL syntax". I tried to store a normal String and it works. Update : This is the query: st.executeUpdate("insert into website(URL,phishing,source_code,active) values('" + URL + "','" + phishingState + "','" + sourceCode + "','" + webSiteState + "');"); I'm using Java. Strings in a SQL query are -usually- surrounded by singlequotes. E.g. INSERT INTO tbl (html) VALUES ('html'); But if the HTML string itself contains a singlequote as well, it would break the
