<p style='margin-top:0;margin-bottom:10px;'>For Oracle databases, Hibernate maps 'text' datatype to the LONG column type, which shouldn't be used anymore (please see <a href="http://docs.oracle.com/cd/B28359_01/server.111/b28318/datatype.htm#CNCPT1831">http://docs.oracle.com/cd/B28359_01/server.111/b28318/datatype.htm#CNCPT1831</a>).</p>
<p style='margin-top:0;margin-bottom:10px;'>For example, the following GORM domain class will be mapped to a table with a 'content' column of type LONG:</p>
<div class="code panel" style="border-width: 1px;"><div class="codeContent panelContent">
<pre class="code-java">class Message
{
<span class="code-object">String</span> content
<span class="code-keyword">static</span> mapping = {
content type: 'text'
}
}</pre>
</div></div>
<p style='margin-top:0;margin-bottom:10px;'>Additionally, if there is more than one 'text' column, creation of the table will result in "ORA-01754: a table may contain only one column of type LONG", e.g. for the following class:</p>
<div class="code panel" style="border-width: 1px;"><div class="codeContent panelContent">
<pre class="code-java">class Message
{
<span class="code-object">String</span> content
<span class="code-object">String</span> other
<span class="code-keyword">static</span> mapping = {
content type: 'text'
other type: 'text'
}
}</pre>
</div></div>
<p style='margin-top:0;margin-bottom:10px;'>The correct behavior would be to create columns of type CLOB. This is not a Grails issue, because the 'text' type is passed to Hibernate and Grails relies on Hibernate in this case. </p>
<p style='margin-top:0;margin-bottom:10px;'>Using CLOB instead of LONG can be achieved on the application level by adding 'clob' sqlType as a workaround, like in the following example:</p>
<div class="code panel" style="border-width: 1px;"><div class="codeContent panelContent">
<pre class="code-java">class Message
{
<span class="code-object">String</span> content
<span class="code-object">String</span> other
<span class="code-keyword">static</span> mapping = {
content type: 'text', sqlType: 'clob'
other type: 'text', sqlType: 'clob'
}
}</pre>
</div></div>
<p style='margin-top:0;margin-bottom:10px;'>but it's only a workaround and doesn't resolve this problem at the source.</p>
<p style='margin-top:0;margin-bottom:10px;'>The default behavior of Hibernate can prevent tables from being created (ORA-0175) and causes creation of tables with a deprecated column type.</p>
