Error message
Table name processing failed :
What it means
Thrown by DynamicTableNameJsqlParserInnerInterceptor when table-name rewriting fails at both layers: JSqlParser could not process the SQL (or produced an UnsupportedStatement whose fallback also failed), the parent DynamicTableNameInnerInterceptor regex/AST-based processing threw, and ignoreException is false (default). It wraps the last underlying exception, so the real cause (usually a JSQLParser parse error) is in the cause chain.

Solutions
- Inspect the wrapped cause (e.getCause()) to find the exact JSqlParser error position and fix the SQL syntax
- Set ignoreException=true on the interceptor so unparseable SQL passes through unrewritten (accepting that the table name is not replaced for that statement)
- Since shouldFallback defaults to true, verify the failure is a genuine parse error in the parent too; if the parent's TableNameParser fails on a false positive, simplify the SQL
- Extract vendor-specific statements out of the intercepted mapper so the interceptor never sees them
Example fix
// before DynamicTableNameJsqlParserInnerInterceptor interceptor = new DynamicTableNameJsqlParserInnerInterceptor(handler); // after (tolerate unparseable SQL, skip rewriting for it) DynamicTableNameJsqlParserInnerInterceptor interceptor = new DynamicTableNameJsqlParserInnerInterceptor(handler); interceptor.setIgnoreException(true);
Defensive patterns
Strategy: try-catch
Validate before calling
// Pre-parse SQL before it reaches the dynamic-table-name interceptor
try {
Statement st = JsqlParserGlobal.parse(sql);
if (st instanceof UnsupportedStatement) {
LOGGER.warn("SQL unsupported by JSqlParser, will fall through: {}", sql);
}
} catch (Exception e) {
throw new IllegalArgumentException("SQL unparseable by JSqlParser: " + sql, e);
} Type guard
static boolean isParseableByJsqlParser(String sql) {
try { JsqlParserGlobal.parse(sql); return true; }
catch (Exception e) { return false; }
} Try / catch
try {
return mapper.insertSpecialDialectSql(entity);
} catch (MybatisPlusException e) {
if ("Table name processing failed : ".equals(e.getMessage())) {
// either route around the interceptor or log & set ignoreException=true
LOGGER.error("Dynamic table name rewrite failed", e.getCause());
throw e;
}
throw e;
} Prevention
- Keep intercepted SQL within JSqlParser-supported dialect syntax
- Consider interceptor.setIgnoreException(true) in environments where unparseable SQL must still run
- Always inspect getCause() — the real JSqlParser error position is there, not in the message
When it happens
Trigger: Executing SQL that JSqlParser cannot parse (vendor-specific syntax like clickhouse/pg extensions, malformed SQL) or an UnsupportedStatement while a DynamicTableNameJsqlParserInnerInterceptor is in the interceptor chain, with default settings (shouldFallback=true already tried, ignoreException=false).
Common situations: Dialect-specific SQL (e.g. PostgreSQL 'RETURNING', MySQL hints, stored procedure calls) routed through dynamic table name rewriting; after upgrading mybatis-plus/jsqlparser where previously-parsed syntax now fails; custom SQL built by string concatenation that is not valid SQL.
