Table name processing failed :

Error message

Table name processing failed : 

What it means

Thrown by DynamicTableNameJsqlParserInnerInterceptor (jsqlparser 4.9 module) when table-name rewriting failed and no recovery was possible: the handler first tries a fallback via the parent interceptor's processTableName, and if that also throws (or fallback is disabled and ignoreException is false) the original exception is rethrown wrapped in MybatisPlusException. It marks the end of the plugin's recovery chain.

Solutions

1. Inspect the wrapped cause (MybatisPlusException wraps the original) to see whether the failure is parse-related or a TableNameHandler bug.
2. If the SQL is valid but unsupported by jsqlparser 4.9, move to the mybatis-plus-jsqlparser-5.0 support module (newer parser) or simplify the statement.
3. Enable ignoreException=true on the interceptor to let un-parseable SQL pass through unchanged when rewriting is best-effort.
4. Fix a throwing TableNameHandler so it never raises for expected table names.

Example fix

// before
DynamicTableNameJsqlParserInnerInterceptor p = new DynamicTableNameJsqlParserInnerInterceptor();
// default: any failure aborts the statement

// after
DynamicTableNameJsqlParserInnerInterceptor p = new DynamicTableNameJsqlParserInnerInterceptor();
p.setIgnoreException(true); // pass SQL through when rewrite fails

try {
    mapper.selectList(wrapper);
} catch (MybatisPlusException e) {
    if (String.valueOf(e.getMessage()).contains("Table name processing failed")) {
        Throwable cause = e.getCause();
        log.error("dynamic table rewrite failed, cause: {}", cause == null ? e : cause);
    }
}

When it happens

Trigger: Executing SQL the configured jsqlparser 4.9 parser cannot parse (unusual syntax, dialect-specific constructs) while rewriting dynamic table names; the plugin's own handling threw 'unsupported', super.processTableName(sql) also failed, and ignoreException=false (default).

Common situations: Complex SQL (window functions, CTEs, vendor-specific hints) supported by the DB but not by the pinned jsqlparser 4.9 parser; mismatch between the jsqlparser runtime on the classpath and the support module version; a TableNameHandler throwing from user code.
