+## Description
+
+I encounter the ORA-01764 "String literal too long" error in Oracle when saving text data using RadEditor. The database column is of type `VARCHAR2`, and the text size, including HTML markup, exceeds the 4000-byte limit allowed for `VARCHAR2` columns in SQL statements. Even though the visible text is smaller, the error occurs due to the inclusion of HTML tags and formatting generated by RadEditor.
+
+## Cause
+
+The ORA-01764 error is caused when the data being inserted or updated exceeds the 4000-byte limit set for `VARCHAR2` columns in Oracle. The limit applies to the total size of the content, including HTML tags and formatting, not just the visible text.
+
+## Solution
+
+### Option 1: Use CLOB for Large Text Content
+
+1. Change the database column type from `VARCHAR2` to `CLOB`.
+2. CLOB columns can store large text content without the 4000-byte restriction.
+3. Modify the SQL statements and data access code to handle CLOB data types.
+
+### Option 2: Restrict Content Size in RadEditor
+
+1. Set the `MaxHtmlLength` property in RadEditor to 4000 or less to prevent exceeding the database limit.
+
+```asp.net
+<telerik:RadEditor ID="RadEditor1" runat="server" MaxHtmlLength="4000" />
+```
+
+2. Note that this limit includes all HTML markup, not just plain text.
+
+### Properties for Limiting Content
+
+- `MaxHtmlLength`: Restricts the total length of the HTML content, including tags.
+- `MaxTextLength`: Restricts the plain text length, excluding HTML tags.
+
+These properties enforce size limitations before the data reaches the database.
